Embodiment

[0029] like figure 1 and 2 As shown in and 3, an intake manifold assembly includes an intake manifold 1 and an oil rail assembly installed on the intake manifold 1. The intake manifold 1 is installed with two sets of oil rail assemblies arranged in front and rear. The ports of the oil inlet pipe 4 and the oil return pipe 5 on the same set of oil rail assemblies are located on the same side as the connecting ends of the external hoses. The connection ends of one set of oil rail assembly 2 and the connection ends of the second set of oil rail assembly 3 in the rear row are respectively located on both sides of the intake manifold 1 . The first set of fuel rail assembly 2 is a methanol fuel rail assembly, the second set of fuel rail assembly 3 is a gasoline fuel rail assembly, methanol is the main fuel, and gasoline is used as a start-up and backup fuel. The ports of the oil inlet pipe 4 and the oil return pipe 5 of the first oil rail assembly 2 are located on the left side of th...

Abstract

An intake manifold assembly for a dual-fuel automobile comprises an intake manifold (1) and a fuel rail assembly mounted on the intake manifold. Two fuel rail assemblies (2, 3) are mounted on the intake manifold. The ports of a fuel inlet pipe (4) and a fuel return pipe (5) of each fuel rail assembly are on the same side as the connecting ends of external soft tubes. The connecting ends of the first and second fuel rails are located at opposite ends of the intake manifold respectively. The intake manifold assembly is neatly arranged in the engine cabin, and the two types of fuel rail are clearly distinguished. The external soft tubes of the fuel rails can easily be distinguished and are conveniently arranged for disassembly and maintenance. The intake manifold assembly controls fuel injection accurately, and ensures the optimal performance of the engine.

Description

technical field [0001] The invention relates to an automobile part, in particular to an intake manifold assembly applied to a dual-fuel automobile. Background technique [0002] With the development of industrial technology, automobiles have become an important means of transportation for people. At present, the main fuel for automobiles is gasoline, which is a non-renewable fuel and causes pollution to the environment. New type of fuel is expected by people, and now the sources of fuel for automobile engines are beginning to diversify, and more and more people pay attention to dual-fuel vehicles. Corresponding to the dual-fuel supply system, as an important part of the intake manifold assembly, which delivers fuel and air for combustion to the engine, its structure must be modified accordingly. The intake manifold assembly is generally composed of the intake manifold and the fuel rail assembly on it. The oil inlet on the intake manifold corresponds to the nozzle installat...
