Several improved technology of diesel generators

Many intuitive impression of diesel generators is bulky, noise big, black smoke, and the structure of the diesel generator is complicated, many people lack of understanding of diesel generator, especially the lack of the understanding of modern advanced diesel generator, diesel generator car in some cities became & other; Restricted object & throughout; By all sorts of discrimination. In fact, after years of research and application of new technology, the present situation of the modern diesel generator has been compared with the past with yu. Modern advanced diesel generator generally USES the electronic control injection, common rail and turbocharged inter-cooled technology, in weight, noise, smoke, etc has made significant breakthrough, achieved the level of gasoline engine. In the aspect of electronic control injection is the main difference between diesel generator and gasoline engine, gasoline engine electronic control injection system is control the air-fuel ratio ( The proportion of gasoline and air) Electronic control injection system of diesel generator is by controlling the fuel injection time to adjust the size of the output, and diesel generator fuel injection control is determined by the speed of the engine and the throttle lever position. Basic working principle is based on computer, therefore, speed sensor and throttle position sensor of the input signal, first calculate the basic injection amount, then according to the water temperature, inlet temperature and inlet pressure of the sensor signal is fixed, and again from control set of position sensor signal feedback correction, the optimum fuel injection quantity. Electronically controlled diesel fuel injection system consists of sensors, ECU ( The computer) And actuators of three parts. Its task is to the electronic control of fuel injection system, implementation of fuel injection quantity and injection timing with the operating conditions of real time control. Use the sensor such as speed, temperature, pressure, the real-time detecting parameters of synchronous input computer, comparing with the third store the values of the parameters, after processing calculation according to the optimal value of fuel pump, exhaust gas recirculation valve, such as preheating plug to control actuator, drive fuel injection system.
