Common rail injection

What is common rail diesel injection? How does a common rail direct injection work?

It features a high- pressure (over 0bar or 2MPa or 20psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles). It’s the high-pressure fuel rail and the computer controlled electronic injectors that make all the difference.

But unlike indirect injection pumps, it is not involved in fuel discharge. Diesel common rail direct injection (CRDI) and its benefits.

This enables Original Equipment Manufacturers (OEMs) to design for optimum performance and exceptional end-user value across a range of machines and applications. Common rail is a fuel injection system found in modern diesel engines. With common rail fuel injection, the combustion process can be optimized to achieve low pollutant levels combined with lower fuel consumption.

Fuel is injected into the combustion chamber from a common rail under high pressure. Common Rail diesel injection is used by most modern diesel engines. A fuel pump delivers diesel fuel to the injectors at very high pressure.

That fuel is sent to the cylinder at pressures measuring up to 20psi. We, at Engineered Diesel, created this video to help our customers have a better understanding of how a common rail diesel injector works, which makes it eas.

One early approach method was to supply more fuel than is needed to the common rail and use a pressure control valve to spill the excess fuel back to the fuel tank.

On diesel engines, it features a high-pressure (0BAR – 20PSI) fuel rail feeding individual solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors or pump nozzles. If you’re unfamiliar with common rail, it is a term that defines the fuel injection system used for these engines.

This is opposed to the traditional direct fuel injection system of using low-pressure pump nozzles to deliver fuel while producing more emissions. The fuel injectors in a common rail -injector system are all supplied by a common rail, or pressure.

When the injectors. Square Injection Rate. Diesel fuel injector as installed in a MAN VDiesel engine. However, most common rail systems use indirect acting (servo actuated) fuel injectors where the pressure is relatively constant throughout the injection event and needle opening rate and maximum lift is.

A common rail is one of the most important components in a diesel and gasoline direct injection system. The main difference between a direct and a standard injection is the delivery of fuel and. Common - Rail -Injector The common - rail system on an internal combustion engine uses an extremely fast solenoid valve in the injector to control the injection process. The armature and valve ball in the solenoid valve move up and open the outlet restrictor when the solenoid is energised.

In the direct injection system, the fuel is directly injected into the combustion chamber, skipping the waiting period in the air intake manifold. It is therefore essential that any fault within a diesel common rail injector is rectified immediately. A High Pressure Pump fed by fuel at transfer pressure. It sends fuel to the rail under very high pressure.

A Low Pressure Actuator named IMV (Inlet Metering Valve). The accumulator directly supplies the injectors with fuel.

Low leakage injector and pump architectures for minimized backflow of heated fuel - for improved fuel economy and. Oil lubricated fuel pump and.

The common rail system of fuel injection is a simple and efficient system. The recent trend in the automobile industry is the usage of common rail direct fuel injection systems in some modern vehicles. Today, manufacturers use CRDi technology to overcome some of the deficiencies of conventional diesel engines which were sluggish, noisy and poor in performance when implemented especially in passenger vehicles. General description.

VPFuel Metering Valve. Designed for distillate diesel fuels. CR-DS-100: Medium-sized common rail injector for engines with cylinder power up to 1kW. A common rail injection engine is a direct injection engine, as far as I know there are no indirect combustion common rail engines, over the years the indirect injection engines produces less cold start smoke but produces less power for the same given cubic capacity.
