Advantages And Functions Of Pencil Ignition Coils

　　Now cars have entered many families, and when everyone starts the car, it is the ignition coil that works. Next, the editor will take you to understand what the pencil ignition coils do, and what advantages they pencil ignition coils have.

　　Pencil ignition coils are to "combine two into one" the high-voltage ignition wire and the ignition coil. Reduce energy loss, enhance combustion, and improve fuel efficiency. Each cylinder is assigned an ignition coil, and the ignition coil is directly installed on the top of the spark plug to reduce electromagnetic radiation and improve the working stability of the onboard electronic device. This ignition method uses camshaft sensors and cylinder knock sensors to achieve precise ignition. It is suitable for engines with any number of cylinders, especially for engines with 4 valves per cylinder.

　　Because the spark plug and ignition coil combination can be installed in the middle of the double overhead camshaft (DOHC), the clearance space is fully utilized. Due to the cancellation of distributors and high-voltage lines, the energy conduction loss and leakage loss are extremely small, and there is no mechanical wear the ignition coil and spark plug of each cylinder are assembled and wrapped with a metal sleeve (iron-clad) outside, which greatly reduces electromagnetic interference and ensures inductance. . It can guarantee the normal operation of the engine electronic control system. On the high-speed gasoline engine of modern automobiles, the ignition system controlled by the microprocessor has been adopted, also known as the digital electronic control ignition system. This ignition system consists of three parts: a microcomputer (computer), various sensors, and an ignition actuator.

　　The ignition coil is an indispensable part of the car, otherwise, the car will not start. Now the most common ignition coils are pencil ignition coils, which are used in most cars.
