Many Jiangxi three-ton sprinklers are not aware of the difference between Jiangxi's 3-ton sprinkler EGR engine and high-pressure common-rail engine. They often ask why high-pressure common rail is more expensive than EGR engine. Next, we will explain to you what is EGR, what is the high pressure common rail, and what is the difference between EGR and high pressure common rail engine? Let you see "EGR and high pressure common rail" as "clear, clear, and honest"! What is an EGR engine? EGR is an exhaust gas recirculation system that uses an electronic control system installed in the pump. Injectors are standard mechanical injectors whose injection control is a positional control. It can barely meet the country's three emission standards, but it does not have the basis to meet the country's four emission standards. EGR can be simply understood as follows: Exhaust gas recirculation means that part of the exhaust gas is reintroduced into the combustion chamber, which reduces the oxygen concentration in the combustion chamber, thereby lowering the combustion temperature and reducing the amount of nitrogen oxides generated. What is a high pressure common rail engine? High-pressure common rail abbreviation: EFI engine, is a more commonly used fuel injection system of modern diesel engines, it is provided by one or two independent high-pressure oil pumps to the diesel engine for fuel, mainly to provide high-pressure fuel rail, is the latest diesel engine A new type of oil supply. EGR gasoline engine fuel pressure is about 4P, diesel high pressure common rail can be much higher, the injection pressure of high pressure 1600 kg or more, and the track pressure is constant, the injector is solenoid valve type, ECU control solenoid valve opening, can achieve a cycle Multiple injections (5 times), precise control, is a type of time control. What is the difference between EGR and high pressure common rail engines? The high-pressure common-rail engine has a technically speaking momentum with respect to the EGR engine. The fuel consumption of the electronic fuel injection system is even lower and the noise is even lower. However, it has a high demand for fuel, and domestic oil technology has not yet reached its standard, so high-pressure nozzle clogging often occurs. High-pressure common rail price disadvantage: At present, China's three high-pressure common-rail engine emissions compared with the standard EGR engine in the price of 1-2 million more expensive, maintenance is also more trouble than EGR and more expensive. EGR life is poor: As the EGR engine uses exhaust gas to reduce the emission of nitrogen oxides, it will easily lead to poor combustion performance of the engine, and the service life will be worse than the high pressure common rail. Conclusion : Jiangxi's 3-ton sprinkler high-pressure common-rail engine is more economical and practical than EGR. It is an inevitable trend for the development of diesel engines in the future. Whether the engine uses high-pressure common rail technology or EGR technology, both will eventually reach the same goal, both to meet higher emission standards and reduce environmental pollution.
