Features of CRDI System:
1. CRDI engine has lower emission. So, it meets latest emission norms. Finely atomized fuel results in an efficient air-fuel mixing & reduced particulate emissions.
2. It gives improved fuel economy.
3. CRDI engine has lower engine noise level. CRDI engines have capability to deliver stable, small pilot injections can be used for decreased NOx emissions and noise.
4. All the cylinders have balanced engine cylinder pressures. (i.e. reduced torsional vibrations).
5. Separation of pressure generation and injection allowing flexibility in controlling both the injection rates and timing of CRDI.
6. In CRDI system, Common rail pressure does not depend on the engine speed and load conditions.
7. In CRDI, High injection pressures (about 1500 bar) and good spray preparations are possible even at low engine speeds and loads.
8. In CRDI system, Fuel pump operates with low drive torque.
9. High pressure accumulator (common rail) provides consistently high pressure fuel to injectors.
10. Use of high pressure pump which allows the fuel to be supply at higher pressure under all operating condition.
