WebJul 24, 2024 · Direct Injection (DI): Injection pressure is higher (21 kg/cm^2) in this case as compared to IDI because fuel atomisation solely depends on pressure of injection. The engines are easier to start in cold weather. Fuel injection nozzles have multiple holes as high atomisation and mixing is required because of a lack of moving air. WebEngines using port fuel-injection typically run lower boost pressures and/or compression ratios than direct injected engines because port fuel injection causes the air/fuel mixture to be heated together, leading to detonation. Conversely, directly injected engines can run higher boost because heated air will not detonate without a fuel being ...

Ultra-high pressure yields superior atomization. And … boats rockville indianaMost direct injection diesel engines have a combustion cup in the top of the piston where the fuel is sprayed. Many different methods of injection can be used. Usually, an engine with helix-controlled mechanic direct injection has either an inline or a distributor injection pump. See more The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel … See more Diesel's idea In 1878, Rudolf Diesel, who was a student at the "Polytechnikum" in Munich, attended the lectures of See more Overview The characteristics of a diesel engine are • Use of compression ignition, instead of an ignition apparatus such as a spark plug. • Internal mixture … See more The fuel is injected at high pressure into either the combustion chamber, the "swirl chamber" or the "pre-chamber" (unlike older petrol engines where the fuel is added in the inlet manifold or carburetor). Engines where the fuel is injected into the main combustion … See more Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This … See more There are several different ways of categorising diesel engines, as outlined in the following sections.
