Method for fuel methanol of igniting type engine

Abstract

The method of burning methanol in an ignition type engine includes the following steps: 1. heating methanol reforming catalyst inside the methanol reformer with electrothermal PTC element and maintaining the temperature at 200-300 deg.c; 2. jetting methanol into the reformer for reaction to produce reformed methanol gas containing hydrogen and CO; 3. mixing the reformed methanol gas and air inside the inlet manifold to form mixed inflammable gas; 4. starting the engine to burn the mixed inflammable gas; and 5. jetting more methanol to form mixed inflammable gas essential for the engine in raised load, so as to make the engine burn mixed gas of nitrogen, CO, methanol and air. The present invention improves the cold start performance of engine burning methanol, eliminates formaldehyde exhaust pollution, raises the burning efficiency, lowers the furl consumption, reduces exhaust pollution and saves petroleum resource.

Description

technical field [0001] The invention relates to a method for burning methanol in an ignition engine. technical background [0002] Cars are mainly powered by gasoline engines or diesel engines, and burn gasoline or diesel. The total number of automobiles in the world is increasing year by year, while oil resources are becoming increasingly exhausted. For this reason, reforming methanol fuel cell vehicles has been vigorously developed at home and abroad. The method is to make methanol pass through a methanol reformer and make part of the methanol oxidation reaction to heat the reforming catalyst. Most of the methanol passes through the reformer at a temperature of 200°C-300°C. Catalyst undergoes a reforming reaction to generate reformed gas mixed with hydrogen and carbon monoxide, and then removes carbon monoxide from the reformed gas, and then inputs the pure hydrogen produced into the fuel cell, where hydrogen and oxygen react in the fuel cell to generate water and output ...
