In the modern high-speed gasoline engine gasoline engine, has been used by the microprocessor control of the ignition system, also known as digital electronic control ignition system. This ignition system consists of microcomputer (computer), a variety of sensors and ignition actuators in three parts.
In fact, in the modern engine, gasoline injection and ignition of the two subsystems are controlled by the same ECU, combined with a group of sensors. The sensors are basically the same as those in an electronically controlled gasoline injection system, such as a crankshaft position sensor, a camshaft position sensor, a throttle position sensor, an intake manifold pressure sensor, a deflagration sensor, and the like. The deflagration sensor is a very important sensor for electronic control ignition (especially the engine with exhaust turbocharger), which can monitor the degree of deflagration and deflagration of the engine as a feedback signal to enable the ECU command to achieve ignition The engine will not be deflated and can achieve higher combustion efficiency.
Digital electric control ignition system (ESA) according to the structure is divided into electrical and non-distributor type (DLI) two types. The electronic type ignition system of the electric distributor only generates a high voltage by using an ignition coil, and then the ignition plugs are ignited in turn by the distributor according to the ignition sequence. As the ignition coil primary coil of the work by the electronic ignition circuit commitment, so the distributor has been canceled off the device, only play a high voltage distribution function.
Double cylinder ignition
Double cylinder ignition means that two cylinders combined with an ignition coil, so this ignition can only be used for the number of cylinders on the even engine. If the two cylinder pistons are close to the top dead center (one is compressed and the other is exhaust), the two spark plugs share the same ignition coil and ignite at the same time, and one is the effective ignition. Invalid ignition, the former in the high-pressure low-temperature mixture, which is in low-pressure high-temperature exhaust gas, so the resistance between the two spark plugs completely different, the energy generated is not the same, resulting in much effective energy , About 80% of the total energy.
Ignition alone
The separate ignition method is to assign an ignition coil to each cylinder, and the ignition coil is mounted directly on the top of the spark plug, which also eliminates the high voltage line. This ignition is achieved by means of a camshaft sensor or by means of cylinder compression to achieve precise ignition. It is suitable for any number of cylinders and is particularly suitable for use with 4-cylinder engines per cylinder. Because the spark plug ignition coil assembly can be installed in the middle of the double overhead camshaft (DOHC), make full use of the gap space. Due to cancel the distributor and high-voltage lines, energy loss and leakage loss is minimal, no mechanical wear, and the cylinder of the ignition coil and spark plugs together, external metal package, greatly reducing the electromagnetic interference, can guarantee the normal engine control system jobs.
