Problems solved by technology

[0003] At present, methanol-fueled vehicles are quite popular in many areas. This type of vehicle usually has only one intake manifold on the original ignition engine or the intake cavity is cast as one with the body. This structure does not use the installation of methanol nozzles. Problems such as uneven mixing, short combustion time, and insufficient combustion affect energy conversion, and methanol is easy to cause carbon deposition, which in turn corrodes the engine

Abstract

The invention discloses a nozzle structure used for multi-point injection of a methanol engine. The nozzle structure consists of methanol nozzles, a gas inlet manifold, a methanol distributor, gas inlet flange cushion blocks, a cylinder cover and an exhaust manifold. The control over the methanol nozzles by all cylinders is realized, the oil injection is more accurate to control, and a combustingeffect of the engine is enhanced. In addition, the sprayed oil mist and fresh air are more uniformly mixed, the thermal efficiency of the methanol fuel engine is effectively improved, and the emissionload of various incomplete combustion products such as HC, CO, etc., can be obviously reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle engines; in particular, it relates to a nozzle structure for multi-point injection of methanol engines. Background technique [0002] In the context of the depletion of petroleum resources, the development of various new clean alternative fuels has become the research focus of various countries. As one of the clean energy sources, methanol has less harmful substances in the exhaust gas of its combustion products, making methanol fuel the first choice to replace petroleum fuel in some provinces, cities and regions in my country. [0003] At present, methanol-fueled vehicles are quite popular in many areas. This type of vehicle usually has only one intake manifold on the original ignition engine or the intake cavity is cast as one with the body. This structure does not use the installation of methanol nozzles. Problems such as uneven mixing, short combustion time, and insufficient combustion affect...
