Problems solved by technology

The heating of the fuel pump itself requires fuel to cool down after flowing through the inside of the fuel pump, which causes the temperature of the fuel in the fuel tank to rise, especially when the amount of fuel in the fuel tank is reduced, the cooling of the fuel pump is significantly reduced, resulting in a longer service life of the fuel pump. In this case, the flow rate of the fuel pump is about 100L / h and all of it flows through the gasoline filter, causing the filter to be replaced when the vehicle is running about 10,000km

Abstract

The invention discloses a non-oil-return type fuel oil supply system for an automobile. The system comprises a fuel tank, an oil pipeline, an engine oil rail and fuel spray nozzles. The non-oil-returntype fuel oil supply system also comprises an oil storage barrel, a fuel pump, a fuel strainer connected with the oil pipeline in series, a pressure sensor for detecting fuel pressure in the oil pipeline, and a controller, which is used for receiving fuel pressure information from the pressure sensor and sending a control signal to the fuel pump according to the received pressure information to control power of the fuel pump and to maintain constant fuel pressure in the oil pipeline. According to the non-oil-return type fuel oil supply system for the automobile, the power of the fuel pump canbe effectively reduced, the service life of the fuel pump can be prolonged, the replacement time of a gasoline filter can be extended, the fuel temperature in the fuel tank can be reduced, fuel consumption can be reduced and vehicle dynamic performance can be improved.

Description

technical field [0001] The invention relates to the field of automobile fuel supply, in particular to a non-return fuel supply system for automobiles. Background technique [0002] The traditional oil return fuel supply system is also called dual-pipeline fuel supply system. Gasoline is sucked out from the fuel tank by the electric gasoline pump, impurities and moisture are removed through the gasoline filter, and the tiny oil produced by fuel injection is eliminated through the gasoline pressure buffer. After the pulsation, the oil pipeline is distributed to the fuel injector of each cylinder, and the fuel injector injects a proper amount of gasoline into the intake manifold of each cylinder according to the instructions issued by the engine electronic control unit (ECU). The fuel pressure is regulated by the gasoline pressure regulator installed at the end of the fuel main pipe, and the excess gasoline flows to the fuel tank through the oil return pipeline. [0003] In or...
