What is the performance of the gasoline pump broken? The precursor to the broken gasoline pump

Introduction:For fuel engines, the focus of general attention is basically on mechanical components such as pistons and cylinders, as well as electronic control units such as ignition and gas distribution.Yuansuperior. Few people know about fuel supply systems, especially gasoline pumps. So about the engine gasoline pump, if it is damaged, what will it behave? If you don't understand the early symptoms, it may lead to catastrophe.

About the role of gasoline pumps

As the most basic component of the engine fuel supply system, the fuel pump is responsible for pumping fuel out of the fuel tank during the working process of the engine, and continuously delivering it to the engine through the fuel supply pipeline at a certain pressure, and then the high-pressure fuel pump Secondary pressurization, and provides a fixed amount of fuel for each cylinder in accordance with the engine's work sequence.

What is the manifestation of a broken gasoline pump?

Generally speaking, we can judge the damage of the gasoline pump by the following signs

① When the vehicle was driving, under the rear seats, the gasoline pump made a "buzzing" noise.

② The engine fault light of the vehicle instrument cluster is always on.

③ When starting the vehicle, it does not catch fire at all, or it is difficult to start.

④ The vehicle is weak to accelerate, especially when it accelerates rapidly, there will be a sense of frustration.

Common causes of damage to gasoline pumps

1. Don't refuel in time

Since the vehicle can still run 40-50 kilometers even when the oil lamp is on, many car owners will not refuel after the oil lamp is on. It should be known that gasoline pumps rely on fuel for cooling and lubrication, and once the fuel in the tank is severely lacking, the fuel pump will easily cause overheating and wear.

2. Poor fuel oil

As the fuel with poor oil quality will contain various impurities, some small impurities are very likely to be sucked in by the oil pump during use, which will cause the wear of the oil cavity. In the long run, the oil pump will inevitably be damaged.

Third, the gasoline filter will not be changed for a long time

The gasoline filter is located between the fuel tank and the engine oil pipeline. If the gasoline filter is not replaced for a long time, it may cause the oil pressure of the gasoline pump to increase due to the accumulation of impurities in the filter. It is inevitable that there will be damage.
