Problems solved by technology
For cylinders without detonation, reducing the ignition angle will reduce the work efficiency of the gas in the cylinder and generate greater exhaust noise
In addition, due to the hysteresis of closed-loop control in knock control, reducing the ignition angle to eliminate knock can only be reflected in the next cycle of the engine, and the harm caused by knock in the current working condition cannot be avoided

The invention provides an engine ignition control system and method. The engine ignition control system comprises a plurality of temperature sensors and a controller, wherein the temperature sensors are arranged inside multiple cylinders of an engine in a one-to-one correspondence mode so as to detect the in-cylinder temperatures of the cylinders in real time; and the controller is connected with the temperature sensors and used for determining the first ignition cylinder according to the ignition sequence of the engine, judging whether the in-cylinder temperature of the first ignition cylinder is higher than the first preset temperature or not, controlling a vehicle to start in a non-cold start mode when the in-cylinder temperature of the first ignition cylinder is higher than the first preset temperature, and controlling the vehicle to start in a cold start mode when the in-cylinder temperature of the first ignition cylinder is lower than the first preset temperature. The accuracy of ignition control can be improved, and the service life of parts inside the cylinders of the engine is prolonged.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to an engine ignition control system and method. Background technique [0002] The normal combustion of the combustible mixture in the engine cylinder depends on many factors, and the temperature in the cylinder is one of them. If the temperature in the cylinder is too high, it will increase the thermal load of the components in the cylinder. At the same time, due to the existence of oil-gas mixture, parts also experience strong electrochemical corrosion at high temperature. Thermal loads and galvanic corrosion both shorten the service life of components. In addition, if the high temperature continues in the engine cylinder, it will also cause knocking. The generation of knocking can reduce the power of the engine, and the parts can be damaged or even the engine is scrapped. Of course, if the temperature of the combustible mixture in the cylinder is very low, due to poor fuel at...
