High pressure common rail test bench with common rail technology
Edit: Taian Sunwe Testing Equipment Co.,Ltd    Date: 2014-05-09
High pressure common rail test bench using common rail technology , the concept refers to the high-pressure pumps, pressure sensors and ECU closed-loop system consisting of the injection pressure generation and injection process is completely separate from each other in a way oil from the high-pressure pump high pressure fuel supplied to the common supply pipe , and through a common hydraulic oil supply pipe to achieve precise control , high-pressure rail pressure and engine speed regardless of size , can significantly reduce engine oil pressure changes with the engine speed , and therefore reduces the shortcomings of the traditional diesel engine. ECU controlled injector fuel injection amount , injection volume depends on the fuel rail ( public for the pipeline ) solenoid valve opening pressure and length of time .
Common rail system uses high pressure common rail test bench , the principle is the fuel pressure generation and fuel injection separated, if the unit pump diesel injection diesel technology revolution in technology than done , then it can be called a rebellion of the common rail because it is a departure from the conventional diesel fuel injection system similar to sequential systems. Common rail system opened up new avenues of reducing diesel engine emissions and noise .
Europe can be said to be a paradise for diesel vehicles , diesel cars in Germany accounted for 39%. Diesel cars has nearly 70 years of history, and the last 10 years can say with rapid development of diesel engines . In 1997 , Bosch and Mercedes-Benz co- developed common rail diesel injection system (Common Rail System). In Europe today , many brands of cars are equipped with common rail diesel engines , such as Peugeot HDI common rail diesel engine alone , Fiat JTD engine, while Delphi is developed Multec DCR diesel common rail systems.
     Common Rail Test Bench electronically controlled high pressure common rail technology (Common Rail) EFI technology , the concept refers to the closed-loop system in the high-pressure pumps, pressure sensors and electronic control unit (ECU) composition, the injection pressure is generated and injection process completely separate from each other as a way to supply . It is a high pressure by the high pressure fuel pump for delivery to a common pipe (Rail), precise control of the hydraulic pressure within the common supply pipe , the high pressure line pressure (Pressure) engine speed regardless of size , can significantly reduce engine extent of oil pressure with engine speed changes .
