The cylinder is the component of the engine where combustion occurs. The combustion in the cylinder is what powers the car. The engine block is normally produced from cast iron or aluminum. Depending on the type of car, an engine may have as few as two cylinders to up to as many as 12 (the Bugatti Chiron has a 16 cylinder engine!). A misfiring cylinder can create a proportional loss of power. For example, if one cylinder misfires in a four-cylinder engine, the vehicle will lose 25 percent of its power.
