After injection in the individual pump and delivery system happens due to which ??
The tool that injects gasoline into a diesel engine's cylinders is called an injection pump. In the past, the camshaft and timing belt, together with gears, chains, or a toothed belt, drove the injection pump indirectly from the crankshaft. In a typical four-stroke diesel engine, it turns at half crankshaft speed. The timing is set up such that the fuel injection occurs just before the top dead centre of the compression stroke for that particular cylinder. It is also typical for the pump belt to be driven directly by the camshaft on gasoline engines. The injection pressure in certain systems can reach 620 bar (8992 psi)
Safety
The pump creates significant pressure since positive injection into a very high-pressure environment is required, generally 15,000 psi (100 MPa) or higher on modern systems. This is a solid reason to exercise extreme caution when working on diesel systems since leaking gasoline at this pressure may pierce skin and clothing and inject into bodily tissues, which might have catastrophic medical repercussions that would need an amputation.
Construction
diesel injection pump inline
Early diesel pumps had an in-line design that resembled a small inline engine with a line of cam-operated injection chambers. The injection volume (i.e., throttling) is regulated by spinning the cylinders against a cut-off port that lines up with a helical groove in the cylinder. The pistons have a constant stroke volume. To create more or less power from the engine, all the cylinders concurrently change their injection volume as they revolve. Large multi-cylinder engines like those used in trucks, construction equipment, stationary engines, and agricultural vehicles still favour inline pumps.
