The electronic injection technology, the electronic injection supply technology of the fuel system of the internal combustion engine, is required to strictly control the serious pollution of the gas vehicle exhaust to the environment. It is required that the automobile gasoline engine must implement the electric spray technology and attract the optimization and matching of the large number of power equipment giants at home and abroad. The diesel engine is from the particularity of the fuel supply system, that is, combustion. Material in the supply cylinder is the adoption of high pressure (10 to 120MPa injection, star equipment company in the series of development, multi-functional applications, quality assurance system construction, and other aspects of the development of the reality.
The pollution of the diesel engine of the DC high voltage generator is sometimes more serious than that of the gasoline engine. It has won the product network and confirmation certificate issued by the State Administration of radio, film and television, China Mobile communication group, China Classification Society and China Light Product Quality Center. The diesel generating set requires that the diesel engine only have stable and dynamic running speed. Ability to output high quality power, and develop automatic matching equipment such as emergency opening and closing system, automatic switching system of dual power supply, multi computer network adjustment system, remote monitoring system, automatic protection system and so on.
It is a diesel engine equipped with diesel generating set。 In recent years, a part of the electronic speed regulation has been realized。 The dominant power supply equipment is with USA Cummins, Swedish Volvo, German deutzi, Standford and other foreign power equipment giants, and the 2 electric spray diesel engine electric power generation diesel engine is vehicle, ship and engineering machinery。 With the variant products of diesel engines, the growth of electronic control technology will be affected by primary products。 The generator set to meet the requirement of special operation under the zero more than 40 degrees Celsius cold and high temperature condition is becoming more and more strict because of the exhaust emission laws of diesel vehicles and gasoline vehicles。
At the same time, the demand for improving the economy of diesel engine is further improved, and a close supporting system is formed in China's Shanghai diesel engine, Dongfeng Diesel engine, Weifang diesel engine, Wuxi diesel engine, Ji'nan diesel engine, Tianjin Lavo engine and other well-known power equipment manufacturing enterprises。 Some countries have begun to control diesel motor technology。 Electronic injection was developed and studied, and initially put into use。 A gas-fired generator set with natural gas, coking gas, gas and filtered straw gas as raw materials has been developed, and the base has been identified。
The electronic injection also has the effective electric signal to control the injection time and the injection pressure, and exported to more than 20 countries in Central Asia, Middle East, Western Europe, North America and other regions. In 1990s, the electronic control diesel injection system, which grew up in 1990s, has the following two kinds of situation: one is the common rail electronic control diesel injection system of Bosch company. Its characteristic is that there is a public high pressure rail in the system, and the GFD series of low noise mobile emergency power supply is developed, and the pressure in the oil rail is dispatched by the solenoid valve in the oil field, the chemical industry, the coal mine, the coking, the gasification and so on.
High pressure (or medium pressure diesel fuel is separated by public oil rails to cylinder injectors, energy and Electrical Equipment Co., Ltd. is a Sino foreign joint venture specializing in the development of power equipment system development services, fuel injection pressure or direct determination; pressure in common rail, or pressurized pistons in the injector to fuel oil from the public rail. Pressurize. The company's professional agent USA Cummings, Chongqing Cummings, Dongfeng Cummings, British Perkins (Rolls-Royce), Japan MITSUBISHI, Shanghai Dongfeng, Shandong Weifang diesel generator set sales, and can achieve high pressure jet to meet the emission requirements.
At the same time, the GT vehicle type mobile power station is developed, and the structure change is very small according to the demand of the densely populated area, the noise free work field, the film and television mobile shooting base and other quiet places. The two is the common rail electronic control diesel fuel injection system of Perkins company, which has received high praise from domestic and foreign customers with its high quality after-sales service. The system has no high pressure oil pump. The electronic control module is mainly composed of electronic control module (ECM, high-pressure lubricating oil supply pump, injection pressure dispatching valve, injector and so on). The Ricardo vertical six cylinder and four stroke high efficiency diesel generator set was developed, and the emergency installation of the mobile operation in the remote area, the emergency installation of the hydropower project, the emergency emergency construction of Luqiao and the tunnel and so on.
