Diesel Common Rail Direct Injection (Crdi) And Its Benefits

Comtháng rail is a fuel injection system found in modern diesel engines. Comtháng rail systems provide a cấp độ of flexibility which can be exploited for class leading emission control, power và fuel consumption. This enables Original Equipment Manufacturers (OEMs) khổng lồ design for optimum performance & exceptional end-user value across a range of machines and applications.

An increasing number of modern diesel engines employ comtháng rail direct injection (CRDi) fuel systems for the flexibility they provide while meeting the most stringent emission control standards.

In comtháng rail systems, the fuel is supplied to the engine under pressure with electronically controlled precision. This provides a level of flexibility which can be exploited for class leading levels of emission control, power and fuel consumption.

How does CRDi work?

The fuel in an electronically controlled engine is stored at variable pressure in a cylinder or ‘rail’ connected khổng lồ the engine’s fuel injectors via individual pipes, making it a ‘comtháng rail’ to all the injectors. The pressure is controlled by a fuel pump but it is the fuel injectors, working in parallel with the fuel pump, that control the timing of the fuel injection & the amount of fuel injected. In contrast earlier mechanical systems rely on the fuel pump for pressure, timing & quantity.

A further advantage of the CRDi system is that it injects the fuel directly inkhổng lồ the combustion chamber. The indirect injection (IDI) system in older engines injected fuel inkhổng lồ a pre-combustion chamber which then fed the main combustion chamber.

What is the advantage of CRDi?

CRDi ensures the fuel injection timing, quantity of fuel & atomisation or fuel spray are controlled electronically using a programmable control module. This allows multiple injections at any pressure at any time (within pre-defined limits), providing a cấp độ of flexibility which can be exploited for better power, fuel consumption & emission control.

How will you notice the benefits of comtháng rail?

Noise, vibration và harshness (NVH) are improved with CRDi as a result of the timing flexibility. Your engine sounds quieter and has a better quality of sound. It also runs smoother. You will see fuel consumption benefits as well because greater injection pressure produces a finer spray of fuel (atomisation) that burns more efficiently.

Better combustion efficiency is a key part of meeting emission standards. Less fuel is wasted as soot or particulates in the exhaust và deposits in the engine. A cleaner running engine is good for the environment – và for the cost of ownership. Cleaner running improves the long-term durability và reliability of your engine.

We have sầu designed our engines to deal with more stringent operating requirements. For example, improved fuel filtration ensures a higher level of purity in the fuel injected from the common rail. Clean servicing procedures are necessary lớn keep your engine running efficiently và within the limits of the applicable emission standards.
