Early on in these efforts, it was apparent that future diesel cars would utilize a direct injection combustion system due to the clear advantage in fuel economy and power density relative to the then prevalent indirect injection combustion system.

The objectives of the developments included driving comfort comparable to that of gasoline fueled cars, compliance with future emission limits and improved fuel economy. diesel common rail

Three groups of fuel system architectures were under consideration: While the efforts around each of these approaches lead to commercial fuel systems for production vehicles, the common rail system provided a number of advantages and would eventually come to dominate as the primary fuel system used in light-duty vehicles.

Fuel pressure independent of engine speed and load diesel common rail. In control terminologythe rail pressure is the system output while the position of the actuator used to control the rail pressure is the system input.

Common Rail Injection System Pressure Control

There are a number of approaches to control diesel common rail pressure in the common rail. One way is to supply more fuel than is needed diesel common rail the common rail and use a high pressure regulator—commonly referred to as a pressure control valve—in the high-pressure circuit to spill the excess fuel back to the fuel tank.

In this approach, the pressure control valve position is the control system input. This allows multiple injections at any pressure at any time within pre-defined limitsproviding a level of flexibility which diesel common rail be exploited for better power, fuel consumption and emission control.

Perkins has a diesel common rail deal of experience with applying CRDi to its diesel common rail controlled engines.

The experience gained over the past 10 years ensures we deliver a competent and capable product at the forefront of prime mover solutions. How will you notice the benefits of common rail? Your engine sounds quieter and has a better quality of sound.

Common Rail Injection System Pressure Control

This characteristic results from "dumb" injectors in the cylinder head which open and close at pressures determined by the spring preload applied to the plunger in the injector.

Diesel common rail the pressure in the injector reaches a pre-determined level, the plunger lifts and injection starts.

The term "common rail" refers to the fact that all of the fuel injectors are supplied by a common fuel rail which is nothing more than a pressure accumulator where the fuel is stored at high pressure.

This accumulator supplies multiple fuel injectors with high-pressure fuel. But if it is a personal vehicle, then you may not want to spend the extra money.

What is function of common rail in diesel engine? - Quora

Expensive Parts — Since the common rail vehicles are more expensive, you can expect that replacement parts are going to be expensive as well. More Maintenance — Common rail diesel engines will need more maintenance than a traditional diesel engine.

Even if you do the maintenance yourself, it still takes more time, effort, and possibly expense. Full Floating Axle Working Principle, Advantages and Disadvantages Conclusion The common rail diesel engine is certainly an advancement in diesel common rail technology that will eventually replace the traditional direct injection system altogether.

Perhaps when this new technology becomes more common in every diesel-powered vehicle, then it will become less expensive.
