Electronically controlled fuel injection devices
In modern automobiles, mechanical or electromechanical hybrid fuel injection systems have tended to be eliminated, and electronically controlled fuel injection devices have been recognized for their superior performance. increasingly popular. The electronic fuel injection device can automatically ensure that the engine is always working in the best condition, so that it can save fuel and purify the air to the maximum extent under the condition of outputting a certain power. After experiments and corrections, the fuel supply control rules under the best operating conditions of the engine are obtained. These objective rules are programmed in advance and stored in the memory of the microcomputer. When the engine is working, according to the air flow measured by each sensor, the content in the exhaust pipe Parameters such as oxygen content, intake air temperature, engine speed and operating temperature are calculated according to a pre-programmed calculation program, and then compared with the parameters of the best working conditions in the memory and judged before adjusting the fuel supply. In this way, the engine can always operate under optimal working conditions, thereby improving the overall performance of the engine.
Electronic ignition
It consists of a microcomputer, a sensor and its interface, and an actuator. The device can calculate and judge based on various engine parameters sent by the sensor, and then adjust the ignition timing, which can save fuel and reduce air pollution. In addition, the new engine electronic control device also has adaptive control, intelligent control and self-diagnostic operations. It is generally believed that the energy-saving effect of engine electronic control devices is above, and the effect is more obvious in environmental protection.
In addition, the use of electronic technology in the engine part includes: exhaust gas recirculation (R), idle speed control (), electric oil pump, generator output, cooling fan, engine displacement, throttle timing , secondary air injection, engine supercharging, oil and gas evaporation and system self-diagnosis functions, etc., they are all used to a greater or lesser extent in different models.
