Problems solved by technology

However, there are certain problems in the application of pure methanol fuel in engines. The low calorific value of methanol and the high latent heat of vaporization make it difficult for methanol engines to start in low ambient temperature and relatively harsh environments, and the engine cannot work normally.

Abstract

The invention relates to the technical field of engine control, in particular to a methanol engine cold starting device and method. Comprising an air inlet manifold installed on the air inlet side of a cylinder cover, the cylinder cover is installed on a cylinder body, a cooling water temperature sensor for detecting the temperature of cooling water is installed in a water jacket of the cylinder body, the water jacket is communicated with a water jacket on the cylinder cover, an air inlet manifold cavity in the air inlet manifold is connected with an air inlet channel of the cylinder cover to form an air inlet flow channel, and a methanol oil sprayer is installed on the air inlet manifold. A rotatable ultrasonic atomization device is mounted on the intake manifold on one side of an oil beam opposite to the methanol oil injector, the ultrasonic atomization device is controlled by an atomization controller, and the atomization controller, the methanol oil injector and the cooling water temperature sensor are all connected with an electronic control unit (ECU) of the methanol engine. According to the invention, the normal starting of the methanol engine at a lower environment temperature and in a severe environment is realized.

Description

technical field [0001] The invention relates to the technical field of engine control, in particular to a methanol engine cold start device and method. Background technique [0002] The fuel used by traditional engines is fossil fuel gasoline and diesel, which are non-renewable energy sources, so they will face the problem of energy shortage and the pollution problem after burning fossil fuels. The application of clean and renewable alternative fuels for engines is imminent. Currently, methanol, as a clean and renewable fuel, can not only be used directly in engines, but also has the highest storage density of hydrogen energy so far. Known as "liquid sunlight", it will surely become the future The backbone of energy. [0003] There have been many researches on the clean renewable fuel methanol replacing fossil fuel gasoline and diesel as fuel for internal combustion engines, and some achievements have been made. However, there are certain problems in the application of pur...
