small, low fuel consumption. The disadvantage is still required high voltage and spark plug
connector, these places is very easy to go wrong.
4）Single Ignition System (CPC)and Integrated ignition system (COP)
Each cylinder has a separate ignition coil, is today's most advanced ignition system.
This ignition system is divided into two types: Single Ignition System (CPC), integrated
ignition system (COP). Integrated ignition system integrated ignition coil in the spark plug,
single ignition system is connecting ignition coil to spark plug with a high voltage wire.
5）Ignition principle
▲The electronic ignition
The electronic ignition system collect information related to the engine with a set of
sensors, such as speed, cooling temperature and engine load, etc. Position sensor and
speed sensor is the most important information required for the ignition system, the
information from the wheel sensors or camshaft sensor. Ignition control module calculates
ignition time and charging time based on the collected information, If a sensor is not
working properly, it will cause the output signal is incorrect, so modern control module
have to check whether the signal sent by the sensor is authentic, when there are
untrusted signal, it may not output any signal. Ignition control module output signal can not
directly drive the ignition coil, have to amplify by ignition amplifier. In fact, ignition amplifier
is mounted in ignition coil generally ， in this case the primary ignition signal is
undetectable；Or mounted in the ignition control module，in this case the ignition control
module output signal is undetectable. Thus, detecting engine fault and performance
through the secondary ignition signal is important.
