Choosing the right spark plug for your engine is essential. In the section below you will find more information to help you choose the right product for your car and understand the importance of certain technological features.

How does a spark plug work?

Gasoline engines have spark plugs, diesel engines have glow plugs, this is the first point. On gasoline engines, the ignition system is external: during the compression cycle, the combustion of the compressed air-fuel mixture is triggered by an electric spark produced by the spark plug.

The spark plug generates this spark

Created by the high voltage produced by the ignition coil. It gushes between the electrodes. A flame front extends from the spark and propagates through the combustion chamber until all the mixture is burned. The heat released increases the temperature. There is then a rapid increase in the pressure in the cylinder, and the piston is pushed down. The movement is transmitted by the connecting rod to the crankshaft; this drives the vehicle through the clutch, the gearbox gears, and the drive shafts.

Requirements of spark plugs

For the engine to run smoothly, be powerful and environmentally friendly, the cylinder must contain the right amount of fuel/air mixture, and the high-energy ignition spark must come out precisely between the electrodes at the predetermined time. This is why spark plugs must meet the most stringent performance requirements: they must provide a powerful ignition spark for hours of driving at high speeds and in accordion traffic conditions. They must guarantee a completely reliable ignition even at -20 ° C. State-of-the-art spark plugs provide low-emission combustion and optimum fuel utilization. Champion candles are designed and manufactured from high-quality materials to consistently meet these extreme requirements.

EACH CHAMPION ® IGNITION CANDLE IS CONSISTING OF FIVE MAIN ELEMENTS

Current candles incorporate a resistor that suppresses radio disturbances.

  1. The base is a threaded metal hex (extruded steel) that seals the combustion chamber and allows the installation and removal of the candle. Each spark plug has a particular thermal index.
  2. The insulation avoids grounding of the high secondary voltage of the coil to any other place that is not between the electrodes, and it transmits the heat released by the combustion process to the cylinder head (and to the cooling circuit ).
  3. The central and ground electrodes determine the position of the spark in the combustion chamber. The gap is the distance between the center electrode and the ground electrode (s). This is the distance that the ignition spark must travel.
  4. Finally, the connection tip connects the spark plug to the ignition system.

Its life depends on its parts

The performance and life of the spark plug are determined by the characteristics of each of its parts. It is a fact. To offer you the most complete range of spark plugs, Champion uses many parts. Their use is the result of technological development and serves to ensure the lifetime that the intrinsic characteristics of these parts can guarantee. In a nutshell, the different elements that make up the spark plug have, each in their own way, an impact on the life cycle and the performance of the product. Champion indicates the technical characteristics and parts of each product on its packaging so that you have all the useful information you need to choose the right candle for your application.
