Fuel injection pumps in diesel engines operate under high pressure.
A device that pumps fuel into gasoline or diesel engine cylinders is known as a fuel injection pump. The pump is usually driven by a chain or toothed timing belt that is motivated by the gears in a crankshaft. This system is also linked to the camshaft, causing them to be intertwined. In traditional four-stroke engines, it rotates at half the speed of the crankshaft in order to enable the correct timing of the injection process. This occurs as the cylinder's compression stroke is about to begin.
These devices are distinctly different from a fuel pump itself, which is primarily responsible for the flow of the fuel from its container or fuel tank. This is the part of the system in which fuel is brought out of the tank and pumped along a system of tubes to the engine block. The fuel injection pump then pushes the fuel inside the cylinders.
Fuel injection pumps need to operate in high-pressure environments in order to keep the system in full containment. In modern systems this is at the level of 15,000 psi or higher. For this reason, mechanics or engineers who work on these systems, especially diesel, take great care for personal safety. The fuel injection pump itself can possibly push fuel into the human body, causing serious harm to an individual.
In larger models, a concept known as in-line injection is the normal model. In this system, the pistons work with a throttle, which can produce varying power levels in the engine. All of the cylinders are rotated at once and the amount of fuel taken in is adjusted by a volume control method.
