Diesel Direct Injection
Diesel direct injection injects fuel directly into the combustion chamber to create the most efficient form of combustion engine. The pressure at which the diesel is injected is the key factor in diesel direct injection. The fuel has to mix swiftly with the compressed air in the cylinder. The higher the pressure, the more finely the diesel is atomised for a fast and intensive mixing of the fuel and air particles. The energy from the fuel is used more effectively and emissions are reduced. We use various injection stages within one power stroke - referred to as multiple injection. Depending on the engine design, revs and load, modern diesel engines use a pilot or double pilot injection and a main injection. Pilot injection achieves smooth combustion, ensuring that the extremely high pressures necessary for combustion to take place are reached more gradually. This significantly reduces combustion noise and cuts emissions.
