Candele a valore termico e conversione by Vespa, Lambretta

Candele by scooter Vespa, Lambretta & Co.

L'universo personale delle candele di Heiko era abbastanza piccolo e semplice:

  • Original engines: BOSCH W5CC
  • Accordatura della luce: BOSCH W4CC
  • In terms of ambiguity: BOSCH W3CC
  • ea volte anche: BOSCH W2CC

Per lui è semper stato so, ma purtroppo da qualche tempo il suo universo è andato in pezzi, perché le candele BOSCH hanno cessato di esistere. Anche se siamo stati ancora in grado di assicurarci un grande stock di BOSCH W3CC. Aggiuntivo, perché abbiamo anche grandi alternative. Ma lavorano in modo diverso ei valori sono diversi ... Motivo sufficiente per affrontare l'argomento delle candele. Trova there Scooter Center la nostra vasta gamma di Candles bypower on dei principali producers spark

The filo della candela

Le candele sono avvitate nella testa del cilindro e sono available in vari diametrie e lunghezze. Le filettature abituali sono M10, M12 and M14.

  • Le Vespe e le Lambrette classic he hanno una filettatura M14.
  • I motori moderni, i motori a quattro tempi ei più recenti motori a due tempi con iniezione di carburante usano candele più piccole come M10 o M12.

Le lunghezze abituali del filetto sono 19 mm (filetto lungo) e 12,7 mm (filetto corto), quindi fate attenzione alla lunghezza corretta della candela e seguite le istruzioni del produttore. Una candela troppo lunga può danneggiare il pistone perché sporge troppo nella camera di combustione, e una candela troppo corta può provocare una perdita di potenza, se il motore si avvia. Ricordate che una combustione poco pulita porterà senza dubbio alla rapida formazione di residui nella camera di combustione, che potrebbero causare danni al motore Long thread short thread spark plug correct length

Value termico

Il valore termico è decided per la resistenza alla fatica termica della candela e per il suo effetto autopulente. Per questo motivo, si fa una distance tra le cosiddette candele fredde e calde. Una candela fredda This means that the engine has a higher temperature than the camera of combustion, so the engine has a higher power in relation to all the cylinders. Una candela calda, d'altra parte, è usata nei motori di produione con un basso carico. Questo tipo di candela raggiunge rapidamente una temperatura elevata, il che significa che la fuliggine che si accumula sulla candela brucia bene. La resistenza alla temperatura è ottenuta con isolanti di diverso design, una candela fredda può dissipare molta temperatura attraverso la testa del cilindro; con una candela fredda, proprio questo viene evitato. Il valore termico non ha niente a che vedere con la resistenza o le prestazioni di una candela. Una candela fredda in un motore freddo (debole) diventa grassa o fuligginosa e può rompersi senza danneggiare il motore stesso. Una candela calda in un motore da corsa brucia e danneggia il motore, di solito gravemente. The valore termico di una candela non è standardizzato. Ogni produttore ha il suo codice:

  • NGK da freddo a caldo = 10-9-8-7-7-6
  • Bosch da freddo a caldo = 2-3-4-5-6
  • DENSO da freddo a caldo = 37-34-31-27-24-22-20-20-16-14

Il materiale dell'elettrodo

Si usano rame, platino, argento o anche iridio. Il rame è il più comune, seguito dall'argento e dal platino. A causa dei prezzi elevati dei metalli preziosi, le candele sono anche più costose delle loro controparti in rame. Gli elettrodi all'iridio estremamente sottili (Ø = 0,6mm) hanno una tensione di accensione più alta e la diffusione del fronte di fiamma nella camera di combustione è migliorata.

Fate attention alla ceramica!

La testa isolante della candela è fatta di ceramica ed è chiaro che la forza bruta non deve essere usata qui. Le candele devono essere maneggiate con cura ed è meglio non farle cadere, inoltre devono essere protette dall'umidità. Usare una key for candles with a rubber insert Spark plug terms values ​​data

Torment è la coppia di serraggio di una candela?

Se it impostato too short, c'è il rischio di perdita di compressione e di surriscaldamento. Anche possibile che l'isolante o l'elettrodo centrale si rompa a causa delle vibrazioni. Se la coppia di serraggio è troppo alta, la candela potrebbe rompersi. L'alloggiamento può anche allungarsi o torcersi. Le zone di dissipazione del calore sono disturbate, c'è il rischio di surriscaldamento e fusione degli elettrodi e persino di danni al motore. I fabbricanti raccomandano una torque wrench for the 'professional installation di una candela. Siccome sappiamo che quasi nessuno lo fa e che non è nemmeno adatto alla Lambretta, si potrebbe, per esempio, seguire la seguente regola generale: Stringere a mano = avvitare a mano e poi stringere di un quarto o mezzo giro con la chiave della candela. La nostra nuova chiave per candele bgm: protegge la candela e ha un magnets per non bruciarsi le dita quando si toglie la candela.

COUNCIL: Puoi pullire the candle with one spazzola metallica Finely lasting the montaggio and the smontaggio.

Imagine della candela

Puoi anche usare l 'image of a candle According to the conclusion of the corretta combustion of the engine. PERFECT: The candle is “fulva”, the motor of the Bruce is perfect. SKINNY: Se la candela è troppo luminosa - bianca, è troppo calda, forse il carburatore è troppo magro o l'accensione è regolata male. FAT (ricco): If you have a black candle and a sparkling light, the motor will work like a rock Spark plug candle picture brown white black lean fat?

Connectore della candela

Nel caso di un connettore per candele, bisogna prestare attenzione al fatto che sia usato con o senza nipplo per candele / dado SAE. The cappuccio della candela è also una parte esposta al calore e alle vibrazioni, quindi dovrebbe essere controllato regolarmente e sostituito se necessario. Un buon cappuccio per candele costa solo pochi euro, il che è un buon investimento. CONSIGLIO: Tengo semper una seconda spina e un cavo di accensione nei miei attrezzi.

Bujías valuable thermico y conversion para motonetas Vespa, Lambretta

spark plugs for scooters Vespa, Lambretta & Co.

The universal personal de bujías de Heiko era bastante pequeño y sencillo:

  • Original engine: BOSCH W5CC
  • Sintonización de la luz: BOSCH W4CC
  • Sintonización ambiciosa: BOSCH W3CC
  • ya veces también: BOSCH W2CC

Así ha sido siempre para él, pero por desgracia, desde hace algún tiempo su universo se desmoronó, ya que las bujías BOSCH dejaron de existir. Aunque, todavía pudimos asegurar and gran stock de BOSCH W3CC. Adicional, porque también tenemos grandes alternativas. Pero funcionan de forma diferente y los valores son otros… Razón suficiente para abordar the tema de las bujías.

in Scooter Center nuestra variada offerta de plugs of the main manufacturers. spark

The rose of the bujia

Las bujías se enroscan en la culata y hay bujías available in varios diametros y longitudes. Las roscas habituales are M10, M12 and M14.

  • The classic Vespas and Lambrettas tienen una rosca M14.
  • Los motores modernos, los de cuatro tiempos y los más nuevos de dos tiempos con inyección de combustible utilizan las bujías más pequeñas como M10 or M12.

Las longitudes de rosca habituales son de 19 mm (rosca larga) y de 12,7 mm (rosca corta), por lo que se debe prestar atención a la longitud correcta de la bujía y seguir las instrucciones del fabricante. Una bujía demasiado larga puede dañar el pistón porque sobresale demasiado en la cámara de combustión y una bujía demasiado corta seguramente tendrá una pérdida de potencia, si es que el motor arranca. Recordemos que una combustión poco limpia provocaría sin duda la rápida formación de residuos en la cámara de combustión, lo que podría causar daños en el motor. Long thread short thread spark plug correct length

Thermal value

El valor thermico it decides para la resistencia a la fatiga thermica de la bujía, así como para su efecto de autolimpieza. Por ello, se distinction between las llamadas bujías frías y calientes.

Una bujia fria It para motors that desarrollan una temperatura muy alta en la cámara de combustión, normalmente motors que tienen mucha potencia en relación a su cilindrada. En cambio, una bujía caliente se utiliza en motores de production con poca carga. First tipo de bujía alcanza rápidamente una temperatura elevada, lo que significa que el hollín que se acumula en la bujía se quema bien. La resistencia a la temperatura se consigue con aislantes de distinto diseño, una bujía fría puede disipar mucha temperatura a través de la culata; con una bujía fría, se evita precisamente esto. El valor térmico no tiene nada que ver con la resistencia o el rendimiento de una bujía. Una bujía fría en un motor frío (débil) se engrasa o se llena de hollín y puede romperse sin dañar el propio motor. Una bujía caliente en un motor de carreras se quema y daña el motor, normalmente de forma grave. El valor térmico de una bujía no está estandarizado.

Cada fabricante tiene su propio code:

  • NGK de frío a caliente = 10-9-8-7-6
  • Bosch de frío a caliente = 2-3-4-5-6
  • DENSO de frío a caliente = 37-34-31-27-24-22-20-16-14

The material of the electrodo

En este caso se utiliza cobre, platino, plata o incluso iridio. El cobre es el más común, seguido de la plata y el platino. Debido a los elevados precios de los metales preciosos, las bujías son también más caras que sus homólogas de cobre. Los electrodos de iridio extremadamente finos (Ø = 0,6mm) are used una tensión de encendido más alta y la propagación del frente de llama en la cámara de combustión mejora.

¡Ten precaución con la ceramica!

The head is made of ceramic and is clear and can not be used by the brutal force. Las bujías deben manipularse con cuidado y es mejor no dejarlas caer, y también deben protectorse de la humedad.

¿Cuál es el par de apriete de una bujía?

Si se ajusta too low, Existe el riesgo de pérdida de compresión y sobrecalentamiento. También es posible que se rompa el aislante o el electrodo central debido a las vibraciones.

If Torque es demasiado alto, la bujía puede romperse. La carcasa también puede estirse o retorcerse. Las zones de disipación de calor están alteradas, el riesgo de sobrecalentamiento y fusión de los electrodos existe, e incluso de daños en el motor. Los fabricantes recomiendan una torque wrench for professional installation de una bujía. Como sabemos que casi nadie lo hace y que ni siquiera sirve para la Lambretta, podrias seguir, por ejemplo, la siguiente regla general:

Apretar a mano = enroscar a mano y luego apretar de un cuarto a media vuelta con la llave de bujías. Nuestra nueva llave de bujías bgm: protect the bujía y tiene un imán para que no se queme los dedos al quitar la bujía.

TIP: Puede limpiar las bujías con un wire brush fino durante el montaje y el desmontaje.

Imagen de la bujía

You can also use the picture of a spark plug para sacar concludes sobre la correcta combustión de su motor.

PERFECT: If you buy it “cervatillo”, your motor is perfect.

LEAN (pobre): Si la vela es demasiado brillante - blanca, está demasiado caliente, posiblemente el carburador está demasiado pobre o el encendido está mal ajustado.

FAT (rica): Si tiene una bujía negra y con hollín, the motor está funcionando demasiado rico. Spark plug candle picture brown white black lean fat?

Connector de bujías

En el caso de un conector de bujía, debe prestar atención a si se utiliza con o sin boquilla de bujía / tuerca SAE. El capuchón de la bujía también es una pieza que está expuesta al calor ya las vibraciones, por lo que debe revisarse regularmente y sustituirse si es necesario. Un buen tapón de bujía solo cuesta unos pocos euros, lo cual es una buena inversión.

CONSEJO: Siempre tengo un segundo enchufe y cable de encendido en misramientas.

Spark plugs heat rate and conversion scooter Vespa, Lambretta

Spark plugs for Lambretta, Vespa & others scooters

My personal spark plug universe is quite small and simple:

  • Original engines: BOSCH W5CC
  • Light tuning: BOSCH W4CC
  • Ambitious tuning: BOSCH W3CC
  • and sometimes even: BOSCH W2CC

That's the way it has always been for me and unfortunately it can't stay that way, because for quite some time now my universe has been crumbling! BOSCH - spark plugs are not existing anymore for a while. Exception: We could still secure a large stock of BOSCH W3CC. But no reason for me to have the world collapsing, as of course there are alternatives. But they are called differently and the smaller value is warm instead of cold ... Reason enough to take on the subject of spark plugs. In our Scooter Center shop you get sparkplugs from all leading manufacturers. spark

Spark plugs thread

Spark plugs are screwed into the spark plug thread of the cylinder head. And they are available in various diameters and lengths. The most common threads are M10, M12 and M14. Classic Vespa and Lambretta sizes are M14 thread. Modern engines, four-stroke and newer two-stroke engines with fuel injection use the smaller plugs with M10 or M12. The common thread lengths are 19mm (long thread) and 12.7mm (short thread). You should pay attention to the correct length of the spark plug and follow the manufacturer's or kit's supplier instructions. A spark plug that is too long can damage the piston as it protrudes too far into the combustion chamber, a spark plug that is too short will certainly have a loss of power if the engine starts at all. However, an unclean combustion would certainly cause residue to quickly form in the combustion chamber, which can cause engine damage or poor running.

Long thread short thread spark plug correct length

Heat value

The heat value is decisive for the thermal fatigue strength of the spark plug and its self-cleaning effect. A distinction is therefore made between so-called cold and hot spark plugs. A cold spark plug is for engines that develop a very high combustion chamber temperature, usually engines that have a lot of power in relation to their capacity. A hot plug, on the other hand, is used in lightly loaded production engines. This type of plug quickly reaches a high temperature, which means that the soot on the plug burns off easily. The temperature resistance is achieved by differently designed insulators. A cold plug can give off a lot of temperature via the cylinder head, while a cold plug strongly inhibits exactly this. The heat rating has nothing to do with the strength or performance of a spark plug. A cold plug in a cold (weak) engine will oil or soot and can break without damaging the engine itself. A hot spark plug in a racing engine will burn up and damage it, usually severely. The heat value of a spark plug is not standardized. Each manufacturer has its own code here.

  • NGK from cold to hot = 10-9-8-7-6
  • Bosch from cold to hot = 2-3-4-5-6
  • DENSO from cold to hot = 37-34-31-27-24-22-20-16-14

The material of the electrode

Copper, platinum, silver or even iridium are used here. Copper is the most common, followed by silver and platinum. Due to the high prices for the precious metals, the spark plugs are also correspondingly more expensive than their copper counterparts. The material is ultimately of interest almost only for wear, only the extremely thin iridium electrodes (Ø = 0.6mm) have a higher ignition voltage, the spread of the flame front in the combustion chamber is improved.

The ceramic plug!

The insulator head of the spark plug is made of ceramic. Clearly, one should not work here with brute force. Spark plugs should be handled carefully and better not be dropped, they should also be protected from moisture. Use a spark plug wrench with rubber inserts. Spark plug terms values ​​data

What is the tightening torque of a spark plug?

If it is set too low, there is a risk of compression losses and overheating. A fracture of the insulator or center electrode as a result of vibrations is also conceivable. If the torque is set too high, the spark plug may break off. The housing can also stretch or twist. The heat dissipation zones are disturbed, and there is a risk of overheating and fusion of the electrodes, or even engine damage. Manufacturers recommend a torque wrench for the Proper installation of a spark plug. Since we know that hardly anyone does this and it doesn't fit at all on the Lambretta, for example, you could follow the following rule of thumb: Hand-tight = tighten by hand and then tighten with the spark plug wrench another quarter to helped a turn. Our new bgm spark plug wrench: protects the spark plug and with magnet so that you do not burn your fingers when removing the plug. TIP: You can clean spark plugs with a fine wire brush after removal.

Spark plug image

You can also use a spark plug image to draw conclusions about the correct combustion of your engine. PERFECT: If the plug is “fawn”, your engine will burn perfectly. LEAN: If the candle is too bright - white, then it is too hot, possibly the carburetor is too lean or the ignition is set incorrectly. RICH: If you have a black, sooty spark plug, then the engine is running too well.

With a spark plug cap, you should pay attention to whether it is used with or without a spark plug nipple / SAE nut. A spark plug cap is also a part that is exposed to heat and vibration and should be checked regularly and replaced if necessary. Good spark plug cap Costs only a few euros, which is a good investment. TIP: I always have a second plug including an ignition cable in my tool.

The heat value is decisive for the thermal fatigue strength of the spark plug and its self-cleaning effect. A distinction is therefore made between so-called cold and hot spark plugs.
A cold candle is for engines that develop a very high combustion chamber temperature, usually these are engines that have a lot of power measured by their cubic capacity. A hot candle, on the other hand, is used in lightly loaded series engines. This type of candle quickly reaches a high temperature, which means that the soot that accumulates on the candle burns away well.
The temperature resistance is achieved through differently designed insulators. A cold candle can give off a lot of temperature through the cylinder head, with a cold candle this is exactly what is prevented. The calorific value has nothing to do with the strength or performance of a spark plug. A cold candle in a cold (weak) engine becomes oily or sooty and can break without damaging the engine itself.
