2014年7月19日 · Most modern engine fuel systems use an advanced technology known as CRDi or Common Rail Direct Injection. Besides, both petrol and diesel engines use a common ‘fuel rail,’ which supplies the fuel to injectors. Furthermore, manufacturers refer to this technology as CRDi in diesel engines.

Common rail direct fuel injection is a direct fuel injection system built around a high- pressure (over 2,000 bar or 200 MPa or 29,000 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles).

CRDi engines are advantageous in many ways. Cars fitted with this new engine technology are believed to deliver 25% more power and torque than the normal direct injection engine. It also offers superior pick up, lower levels of noise and vibration, higher mileage, lower emissions, lower fuel consumption, and improved performance.

An increasing number of modern diesel engines employ common rail direct injection (CRDi) fuel systems for the flexibility they provide while meeting the most stringent emission control standards. In common rail systems, the fuel is supplied to the engine under pressure with electronically controlled precision.

The denotation of CRDi in an engine’s name simply states that the engine in question uses the CRDi fuel injection system to send fuel, in this case, diesel, into the pistons for combustion. Components like a common rail, an injector, and an ECU (Electronic Control Unit) are some of the key components in a CRDi diesel engine.

2019年11月30日 · CRDI system can control the flow of fuel in accordance with the load and speed of the engine. This system requires only one fuel pump for multiple cylinders. CRDI system is beneficial for the environment as it reduces noise, smoke and particulate matter.

2023年8月27日 · A CRDi engine, short for "Common Rail Direct Injection" engine, is an advanced type of fuel injection system specifically designed for diesel engines. It has revolutionised the way diesel engines function, offering numerous advantages over traditional fuel injection systems.

2023年9月6日 · A CRDi injector works by precisely controlling pressurised fuel delivery into the engine's combustion chamber through an electronically controlled valve, resulting in efficient combustion and improved engine performance.

CRDi stands for Common rail direct injection which means the direct injection of fuel into the cylinder of a diesel engine through a single common line called common rail which is connected to fuel injectors.

One of such technologies is called Common Rail Direct Injection (CRDI) system of direct fuel injection. In this system, commencement of combustion takes place directly into the main combustion chamber located in a cavity on the top of the piston crown.
