Reply Victoria College , send you a truck information platform, and regularly update

High -pressure common rail ? What is the hell of the high -voltage common rail fuel system?

has an opportunity to turn on the "God Perspective" to see the common rail system . Do you want it?

"Want!" ... It seems that Xiaobian guessed that Victoria's hearts have gone ~

will talk to you today about the ghost of high -pressure co -track?

"High pressure" refers to fuel injection system pressure than diesel engine

is 3 times higher, up to 200 MPA

, and traditional diesel oil injection pressure is 60 — 70 MPA

"common rail" is through public oil supply pipes At the same time, the fuel jet mouth

fuel injection volume is accurately calculated by ECU, and at the same time, it provides fuel with the same quality and the same pressure on each fuel jet mouth

to make

even more Pingshun, thereby optimizing the comprehensive performance of diesel engine

and traditional diesel engine Each cylinder is not consistent with the amount and pressure of each cylinder of oil injection

, and the uneven operation

causes unstable combustion, high noise, high fuel 3

diesel engine development experience The experience is that develops from mechanical control to electronic control.

's traditional diesel engine is a direct -injection, synthetic pump, and mechanical control fuel system engine

. The new diesel engine currently is a direct injection, high -voltage rail, and electronic control fuel system engine.

high -voltage co -track fuel system has only electronic control methods.

mechanical control method is difficult to achieve precise control over high -voltage co -fuel fuel systems.

traditional diesel engine fuel system

high -pressure co -rail working principle

high -pressure oil pump sent the fuel to the common rail through high oil pipe,

co -track pressure signal was passed to ECU

and then ECU transport the signal to the electromagnetic electromagnetic of the high -pressure oil pump

controls the control of common rail pressure

high -pressure fuel in

through high -pressure oil pipe . The signal from the ECU controls the opening time of

each cylinder injector and the length of the opening time.

ECU collects various information at any time at any time. Control of working conditions.

Do you have such troubles?

does it take for a long time? maintenance personnel flow too fast? The content of the information bought by is mixed? The information set by is less than a long time?
