Working method

 

NC ignition voice
 

In the high-speed gasoline engine of modern automobile, the ignition system controlled by microprocessor, also known as digital electronic control ignition system, has been adopted. The ignition system consists of microcomputer (computer), various sensors and ignition actuator.

In fact, in modern engines, gasoline injection and ignition subsystems are controlled by the same ECU and share a group of sensors. The sensors are basically the same as those in the electronic gasoline injection system, such as crankshaft position sensor, camshaft position sensor, throttle position sensor, intake manifold pressure sensor, deflagration sensor, etc. The deflagration sensor is a very important sensor dedicated to electronic ignition (especially the engine with exhaust turbocharger). It can monitor whether the engine deflagration and the degree of deflagration. As a feedback signal, it can make the ECU command to realize ignition in advance, so that the engine will not deflagration and can obtain high combustion efficiency.

According to the structure, the digital electronically controlled ignition system (ESA) is divided into distributor type and non distributor type (DLI). The distributor type electronic ignition system uses only one ignition coil to generate high voltage, and then the distributor ignites the spark plugs of each cylinder in turn according to the ignition sequence. Since the on-off work of the primary coil of the ignition coil is undertaken by the electronic ignition circuit, the distributor has cancelled the breaker device and only plays the function of high-voltage power distribution.

 

Two cylinder ignition

 

Two cylinder ignition mode means that two cylinders share one ignition coil, so this ignition mode can only be used on engines with even number of cylinders. On a 4-cylinder engine, when the pistons of two cylinders approach TDC at the same time (one is compression and the other is exhaust), the two spark plugs share the same ignition coil and ignite at the same time. At this time, one is effective ignition and the other is invalid ignition. The former is in the mixture of high pressure and low temperature, and the latter is in the exhaust gas of low pressure and high temperature, Therefore, the resistance between the two spark plug electrodes is completely different, and the energy generated is also different, resulting in much greater energy for effective ignition, accounting for about 80% of the total energy.

 

Separate ignition

 

The separate ignition mode is to assign an ignition coil to each cylinder, and the ignition coil is directly installed on the top of the spark plug, which also eliminates the high-voltage wire. This ignition mode realizes accurate ignition through camshaft sensor or monitoring cylinder compression. It is suitable for engines with any number of cylinders, especially for engines with 4 valves per cylinder. Because the spark plug 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 the distributor and high-voltage line, the energy conduction loss and leakage loss are very small and there is no mechanical wear. Moreover, the ignition coil and spark plug of each cylinder are assembled together and wrapped with metal, which greatly reduces the electromagnetic interference and can ensure the normal operation of the engine electronic control system.
