CRDI (Common Rail Direct Injection) Technology in Hindi | How CRDI Engine Works?

CRDi stands for Common Rail Direct Injection meaning, direct injection of the fuel into the cylinders of a diesel engine via a single, common line, called the common rail which is connected to all the fuel injectors.
Whereas ordinary diesel direct fuel-injection systems have to build up pressure anew for each and every injection cycle, the new common rail (line) engines maintain constant pressure regardless of the injection sequence. This pressure then remains permanently available throughout the fuel line. The engine's electronic timing regulates injection pressure according to engine speed and load. The electronic control unit (ECU) modifies injection pressure precisely and as needed, based on data obtained from sensors on the cam and crankshafts. In other words, compression and injection occur independently of each other. This technique allows fuel to be injected as needed, saving fuel and lowering emissions.
More accurately measured and timed mixture spray in the combustion chamber significantly reducing unburned fuel gives CRDi the potential to meet future emission guidelines such as Euro V. CRDi engines are now being used in almost all Mercedes-Benz, Toyota, Hyundai, Ford and many other diesel automobiles.
In common rail systems, a high-pressure pump stores a reservoir of fuel at high pressure - up to and above 2,000 bars (psi). 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. This simplifies the purpose of the high-pressure pump in that it only has to maintain a commanded pressure at a target (either mechanically or electronically controlled). The fuel injectors are typically ECU-controlled. When the fuel injectors are electrically activated, a hydraulic valve (consisting of a nozzle and plunger) is mechanically or hydraulically opened and fuel is sprayed into the cylinders at the desired pressure. Since the fuel pressure energy is stored remotely and the injectors are electrically actuated, the injection pressure at the start and end of injection is very near the pressure in the accumulator (rail), thus producing a square injection rate. If the accumulator, pump and plumbing are sized properly, the injection pressure and rate will be the same for each of the multiple injection events.

[@averma9574]

Direct injection engine ke bare me batao sir 👍👍

[@MECHANICALTECHHINDI]

Okay

[@sahilafsar9837]

Sir g differential se related

[@MECHANICALTECHHINDI]

Okay

[@ExplorerEngineer108]

IN MPFI AIR FUEL MIXTURE GO WITH MIXING ONCE TIME IN SUCTION STROKE BUT IN CRDI AIR GO TO CYLINDER IN 1ST STROKE THEN FUEL GO TO CYLINDER IN 3RD POWER STROKE AM I RIGHT ??

[@AbhishekYadav-iw6tt]

In 2nd stroke when air is compressed in the cylinder the injector inject tha fuel in the cylinder then the combustion will be happed due to high compression of air (when air will be compressed the temperature of air will be increased at the compression time )then it generate heat with the help of fuel which is injected through the injector.
