Introduction And Advantages Of Pencil Ignition Coils?

　　As the name implies, pencil ignition coils are ignition coils shaped like a pen.

　　Pencil ignition coils integrate high-voltage ignition wire and ignition coil trigger module, which reduces energy loss, improves combustion and improves 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 gap 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, and the ignition coil and spark plug of each cylinder are assembled and wrapped with a metal sleeve (clad iron), which greatly reduces electromagnetic interference and ensures inductance.

　　It can guarantee the normal operation of the engine's electronic control system.

　　In terms of structure, pencil ignition coils make the structure of the engine more concise, without a single ignition coil, but in terms of performance, pencil ignition coils enable each cylinder to be equipped with a separate ignition coil, so that the ignition between each cylinder is independent of each other, can better ensure the ignition energy, avoid mutual interference, and make full use of the gap space.

　　Advantages of pencil ignition coils

　　The pen-type ignition coil has high ignition energy, more stable performance, and is convenient for EFI control. It is easy to use, install, and maintain. It also integrates some optimized control circuits to make ignition control better.

　　Electromagnetic interference is greatly reduced.

　　In addition, pencil ignition coils are an integrated ignition control module and ignition coil, suitable for sequential independent ignition of multiple cylinders, which can reduce costs and facilitate maintenance.

　　The pencil ignition coils integrate the ignition coil and the trigger module and are suitable for sequential ignition engines. Compared with group ignition, it is easier to calibrate and control, and the ignition energy is high.
