The first connection between the fuel filter and the oil pump is the oil inlet pipe, and the thinner oil pipe returned from the fuel injector is the oil return pipe.

There are three types of oil pumps: In-line type, distribution type and single type. No matter which type, the key of oil pump lies in the word “pump”. The quantity, pressure and time of pump oil shall be very accurate and automatically adjusted according to the load. Oil pump is a component with fine processing and complex manufacturing process. The oil pump of general automotive diesel engine at home and abroad is produced by a few professional factories in the world.

The oil pump can only operate with a power source, and the camshaft at the lower part of it is driven by the engine crankshaft gear. The key part of the fuel injection pump is the plunger. If we compare it with the common syringe in the hospital, the movable plug is called the plunger, and the needle cylinder is called the plunger sleeve. Suppose a spring is installed in the needle cylinder against one end of the plunger, and the other end of the plunger contacts the camshaft. When the camshaft rotates for one week, the plunger will move up and down in the plunger sleeve once, This is the basic movement mode of fuel injection pump plunger.

The plunger and plunger sleeve are very precision parts. There is an inclined groove on the plunger body, and a small hole on the plunger sleeve is called the suction port. This suction port is filled with diesel. When the inclined groove of the plunger faces the suction port, the diesel enters the plunger sleeve. When the plunger is pushed to a certain height by the camshaft, the inclined groove of the plunger is staggered with the suction port, and the suction port is closed, so that the diesel can neither be sucked in nor pressed out. When the plunger continues to rise, it compresses the diesel, When the diesel pressure reaches a certain level, it will open the check valve and rush out into the fuel injection nozzle, and then enter the cylinder combustion chamber from the fuel injection nozzle. Each time the plunger discharges a certain amount of diesel, only part of it is injected into the cylinder, and the rest is discharged from the oil return hole, and the fuel injection quantity is adjusted by increasing or decreasing the discharged oil return quantity.

When the plunger rises to the “upper point” and moves down, the inclined groove of the plunger will meet the suction port again, and the diesel oil will be sucked into the plunger sleeve again. Repeat the above action again. Each group of plunger system of in-line fuel injection pump corresponds to one cylinder, and there are four groups of plunger systems in four cylinders. Therefore, the volume is relatively large and is mostly used in medium-sized and above vehicles. For example, diesel engines on buses and trucks generally use in-line fuel injection pumps.
