Embodiment Construction

[0015] With reference to Fig. 1, Fig. 2, it can be seen that the device for gasoline engine burning methanol cracked gas of the present invention, in addition to comprising the existing gasoline engine gasoline injection control system, has also installed methanol cracked gas injection valve 1, methanol supply system, methanol The cracking device 7 and the fuel switching system heat the methanol cracking device 7 so that the methanol is cracked into carbon monoxide and hydrogen under the action of the catalyst for use by the engine.

[0016] Among them, the methanol supply system consists of a methanol tank 4, a methanol pump 5, and a methanol injection valve 6, and is mainly used for storage of methanol and supply to the cracking device 7.

[0017] The methanol cracking device 7 mainly includes components such as a chamber 16, a cracked gas outlet pipe 10, a catalyst 11, a preheating pipe 12, an alcohol rail 13, a methanol nozzle 14, and a cooling nozzle oil return pipe 15. Th...

Abstract

The invention provides a device for cracking the burnt methane of a gasoline engine. The invention is provided with a methane cracking air injection valve, a methane providing system, a methane cracking device and a fuel switching system mainly on the basis of the prior gasoline motor injection control system. The methane is cracked into carbon monoxide and hydrogen under the action of a catalyst by heating the methane cracking device and the carbon monoxide and the hydrogen are used for the engine. The device can realize the quick combustion and solve the problem that cold starting is difficult to carry out by burning methane; moreover, the device has simple structure and convenient use, thereby easing the energy shortage situation of a country; in addition, the burning of the cracked methane can greatly improve the vehicle discharge level and the fuel economical efficiency.

Description

technical field [0001] The invention relates to a gasoline engine device, in particular to a device for burning methanol cracked gas in a gasoline engine. Background technique [0002] The two oil crises that occurred in the 1970s made many countries actively seek alternative energy sources for oil. Methanol has a promising future as an alternative fuel. Methanol is a substance with high oxygen content. The air coefficient can be much smaller than the value required when burning gasoline, and the combustion is more complete; in the case of high oil price and low methanol price, methanol fuel has a great advantage economically. However, due to the high ignition temperature of methanol, compression ignition is very difficult, and there is a problem of carbon deposition in the engine; even if it is applied to ignition engines, because the net calorific value of methanol is less than half that of conventional gasoline, the fuel has poor ignitability and high latent heat of vapor...
