Method for auxiliary pressurization of heavy oil rail through air

Abstract

The invention discloses a method for auxiliary pressurization of heavy oil rail through air. The method comprises the following steps that an engine drives an air compressor to press the air, and meanwhile, an ECU of the engine sends an instruction to an electromagnetic pump to incorporate the fuel oil into a fuel oil pressurization chamber of the oil rail, a pressure sensor on each containing chamber on the oil rail feeds back a pressure value to the ECU of the engine correspondingly, when both the oil pressure and the air pressure on the oil rail reach a designed pressure value, electromagnetic valve instructions of an air nozzle and an oil nozzle given by the ECU enable two electromagnetic valves to inject the air and the oil into a oil-gas mixing chamber, when the pressure in the oil-gas mixing chamber reaches a proper value, the ECU commands the fuel gas electromagnetic valves to be opened and closed according to the feedback information, so that the heavy oil fuel gas is injectedinto a combustion chamber, and the ignition of the heavy oil is realized. According to the oil rail, the method for auxiliary pressurization through the air is utilized, heat energy carried by the air is utilized, the fuel gas atomized can be warmed up, so that the heavy oil reaches an ignition effect similar to that of clear oil, and the purpose that the heavy oil can be used on an ignition typeengine is achieved.

Description

technical field [0001] The invention relates to the technical field of oil rail pressurization, in particular to a method for air-assisted pressurization of an oil rail. Background technique [0002] The oil rail can also be called the oil pipe and the oil guide rail. The oil rail can send fuel to the injector through the pressure of the electromagnetic pump. The oil rail plays the role of transmission and is more common in some mechanical equipment such as engines. [0003] At present, energy saving and environmental protection have become important topics in today's society. In the past, during the use of machinery, the exhaust gas was often discharged into the surrounding environment due to its large displacement, causing serious pollution to the surrounding environment. At the same time, the fuel could not be fully discharged Combustion leads to waste of energy, thereby increasing economic costs, so the improvement of some mechanical displacements is particularly importa...

Problems solved by technology

[0005] The object of the present invention is to provide a method for oil rail to be assisted by air to solve the problem that the existing oil storage tank in the above background technology has no filtering device inside when it is in use, so that the impurities in the oil will pass through the connecting oil pipe and the oil. Into the oil-air mixing chamber together, this will cause blockage of the connecting pipe after a long time of use, affecting the normal use of the entire machine, and when the air is mixed with the oil, the mixing progress is slow, causing the oil temperature to rise slowly and reduce the air temperature. The mixing efficiency with the fuel further affects the fuel effect
