Ignition system type

 

In the high-speed gasoline engines of modern automobiles, an ignition system controlled by a microprocessor has been adopted, also known as a digital electronically controlled ignition system. This kind of ignition system consists of three parts: a microcomputer (computer), various sensors and ignition actuators.

 

In fact, in modern engines, both the gasoline injection and ignition subsystems are controlled by the same ECU, and a set of sensors are used together. The sensors are basically the same as those in the electronically controlled gasoline injection system, such as a crankshaft position sensor, a camshaft position sensor, a throttle position sensor, an intake manifold pressure sensor, and a knock sensor. Among them, the knock sensor is a very important sensor dedicated to electronic control ignition (especially the engine with exhaust gas turbocharger). It can monitor whether the engine knocks and the degree of knock, as a feedback signal to enable the ECU command to achieve ignition advance, so that The engine will not deflagrate and can obtain higher combustion efficiency.

Digital Electronically Controlled Ignition System (ESA) is divided into two types: distributor type and distributorless type (DLI) according to the structure. The distributor-type electronically controlled ignition system uses only one ignition coil to generate high-voltage electricity, and then the distributor ignites the spark plugs in each cylinder in sequence 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 role of high-voltage power distribution.

 

The dual-cylinder ignition method means that two cylinders share an ignition coil, so this ignition method can only be used on engines with an even number of cylinders. If on a 4-cylinder engine, when the two cylinder pistons are close to the top dead center at the same time (one is for compression and the other is for exhaust), the two spark plugs share an ignition coil and ignite at the same time. At this time, one is effective and the other is ineffective. For ignition, the former is in a mixture of high pressure and low temperature, and the latter is in a low pressure and high temperature exhaust gas. Therefore, the resistance between the spark plug electrodes of the two is completely different, and the energy generated is different, resulting in a much larger effective ignition energy. About 80% of the total energy.

 

The individual ignition method is to allocate 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 line. This ignition method achieves precise ignition by camshaft sensors or by monitoring cylinder compression. It is suitable for engines with any number of cylinders, and is especially suitable for engines with 4 valves per cylinder. Because the spark plug ignition coil assembly can be installed in the middle of the double overhead camshaft (DOHC), the gap space is fully utilized. Due to the elimination of distributors and high-voltage lines, the energy conduction loss and leakage loss are extremely small, and there is no mechanical wear. Moreover, the ignition coil and spark plug of each cylinder are assembled together, and the outer metal is wrapped, which greatly reduces electromagnetic interference and can ensure the normal engine electronic control system. Work.
