Common Rail Direct Injection For Diesel Engine

Common Rail Direct Injection For Diesel Engine simulator allows the study, the testing and the troubleshooting on HDI (CDI CR) injection systems for diesel engines that, similarly to what happens for the traditional injection petrol engines where, however, the pressure of the fuel is only few bars, use a high pressure electric pump and a single manifold to connect the pump to the electro-injectors, which are electronically and individually controlled for what concerns the start and the duration of the injection. In the conventional diesel engine the rotation speed of the engine controls the pressure to the injectors and, furthermore, pressure and injection are strictly correlated, because only when the pressure exceeds a given threshold there is the mechanical opening of the injector

The advantages of the Common Rail Direct Injection For Diesel Engine:

1. High pressure also at low regimes
2. Excellent atomization and dispersion of the fuel
3. Increase of the torque
4. Reduction of the noise
5. Reduction of the consumptions and of the emissions.

The main components that characterize a Common Rail Direct Injection For Diesel Engine are the following:

1. Fuel tank with pre-filter
2. High pressure electro-pump
3. Flow limiter
4. Common rail with electro-injectors, fuel pressure limiting valve and relevant pressure sensor
5. Electronic control board for the management of the whole plant
6. Engine rpm sensor
7. Accelerator pedal position sensor
8. Over supply pressure sensor
9. Air temperature sensor
10. Engine temperature sensor
11. Air mass sensor
12. Pneumatic actuator for the variable geometry turbine
13. Computerized workstation linked to the management system
