Problems solved by technology
Methanol, as a coal-based fuel, has the problems of low calorific value, poor cold start and insufficient combustion leading to high unconventional emissions
Patent Nos. 200420029911.9 and 200620127767.1 disclose a cold start device for an engine fueled by methanol, which solves the problem of poor methanol cold start by preheating the methanol fuel when the engine is about to be cold started. The problems of low value and high unconventional emissions have not been solved, which makes the current methanol engine not suitable for large-scale promotion and use

Abstract
The invention aims to provide a methanol engine with high efficiency and low emission, comprising a cylinder body provided with a piston inside and a cylinder cover covered on the cylinder body, wherein, the cylinder cover is provided with a spark plug, an intake valve connected with an inlet pipe, and an exhaust valve connected with an exhaust pipe, particularly, the surface of the head of the piston is provided with a coating layer with a composition of a catalyst for reforming methanol; and the catalyst for reforming the methanol can be plumber white, etc. The methanol engine with high efficiency and low emission has simple structure and low cost; and compared with the prior methanol engine, the methanol engine with high efficiency and low emission has higher efficiency and good emission performance and is suitable for being popularized and used today when petroleum resources dry up increasingly.
Description
A high-efficiency and low-emission methanol engine technical field The invention relates to an engine, especially an engine using methanol as fuel. Background technique At present, there are more and more cars using petroleum-based fuels such as gasoline and diesel, and petroleum resources are increasingly depleted. In order to cope with the increasingly serious petroleum energy crisis, all countries are actively developing alternative fuels. Therefore, the development of coal-based fuels is in line with my country's energy strategy. As a coal-based fuel, methanol has the problems of low calorific value, poor cold start, and insufficient combustion, resulting in high unconventional emissions. Patent Nos. 200420029911.9 and 200620127767.1 disclose a cold start device for an engine fueled by methanol, which solves the problem of poor methanol cold start by preheating the methanol fuel when the engine is about to be cold started. The problems of low value and high unconventi...
