Hitachi Ignition Coil

A crank sensor is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters.

An ignition coil (also called a spark coil) is an induction coil in an automobile’s ignition system that transforms the battery’s voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel.

The material of the pressure valve uses a silicon rubber. Silicon rubber has the characteristic of being resistant to heat. It has higher temperature durability of 100℃ and more than other synthetic rubbers such as NBR and EPDM which were conventionally used.
