A diesel pump or as it is regularly known an injection pump typically is used to fuel a diesel engine, injection pumps can be utilized to deliver fuel to a petrol engine also. A diesel pump, in the first engines, would have been powered by the engine using a connection directly to the engines crankshaft. The diesel pump will be timed to inject the diesel into the engine at the correct time in the pistons stroke.

Commonly a diesel engine in your standard car, van or lorry will be of the four stroke variety, larger engines used in ships and large machinery will frequently be of the two-stroke variety to raise fuel efficiency. Two-stroke engines you would as a rule find in a strimmer or model car, of course these use petrol to run.
The main variation with a two-stroke engine is that the first and ultimate strokes are performed simultaneously, this has the consequence of drastically increasing efficiency at the price of a dirtier exhaust. Another benefit is that two-stroke engines can be effortlessly run in reverse, providing a reverse function without the requirement for intricate gearing mechanisms. In the up to date motor there are two main sorts of diesel engine, those are the common rail diesel engine and the electronic unit direct injection.
An electronic unit direct injection assembly combines the injector and diesel pump into a singe unit, the diesel pump is, commonly, still driven by the engine. An Overhead Camshaft (OHC) drives the diesel pumps and injectors, this is an assemblage sat on top of the engine and fixed directly to the engines main cam shaft by chain, or more commonly now, a belt.

The common rail diesel engine consist of a high pressured fuel rail, in essence a manifold, supplying single diesel fuel injectors versus the diesel pump delivering fuel directly to the fuel injectors.
As mentioned, above, your recent diesel engine works on a four stroke cycle. You may well have heard this named the Otto cycle after the inventor of the petrol motor, Nikolaus August Otto in 1876. A few years afterward Rudolf Diesel came along and, wishing to invent a more fuel efficient motor, came up with the diesel engine in 1892.
Diesel engines have been a bit sluggish on the up-take, for the typical everyday van, largely due to their reputation of being noisy and smelly. Obviously this is changing as modern technology makes the diesel engine a more acceptable resolution to our current transportation woes.
One downside to diesel fuel as opposed to petrol is when used in very cold climates. Diesel will begin to freeze at a higher temperature than gasoline, this will start off by the diesel becoming thicker and waxy, clearly this will hinder the good running of any diesel engine. One technique is to put a tiny amount of petrol into the diesel fuel mix to help lower the freezing point of the overall mixture.
This additionally has the additional gain of making the overall combination more explosive, however too great a mixture can damage a diesel engine, even small amounts of petrol in a common rail engine can cause critical problems so talk to an experienced mechanic before varying your fuel combination.
