Problems solved by technology

However, methanol will produce formaldehyde after burning, which is very harmful to the human body.
However, when gasoline is used as fuel, the main emissions are CO, HC and NOx, and the single application of both has relatively large defects.
Some researchers put gasoline and methanol into a fuel supply tank after mixing. In this case, the effect is not very good because the ratio of the two is fixed, and the emissions and efficiency vary with the current state of the engine.

Abstract

Disclosed is an automobile dual fuel mixing system. The automobile dual fuel mixing system comprises a methanol fuel tank and a gasoline fuel tank. The methanol fuel tank is connected with a methanol spray nozzle, the gasoline fuel tank is connected with a gasoline spray nozzle, the methanol spray nozzle and the gasoline spray nozzle are both connected to an engine gas inlet vent and an engine management system, and the engine management system control the on and off of the valves of the spray nozzles. The automobile dual fuel mixing system can control the proportion of methanol and gasoline at the gas inlet vent timely according to the current condition through the engine management system, and accordingly to obtain the optimal proportion among the emission quantities of CO, HC, NOx and formaldehyde to reduce pollution.

Description

technical field [0001] The invention relates to the field of automobile fuel, in particular to a simple activity room. Background technique [0002] At present, methanol has become a mature vehicle fuel, with high octane number, good anti-knock performance and high oxygen content, which can reduce conventional emissions such as CO, HC and NOx from vehicles. However, methanol will produce formaldehyde after burning, which is very harmful to the human body. When gasoline is used as a fuel, the main emissions are CO, HC and NOx, and both of them have relatively large defects. Some researchers mixed gasoline and methanol into a fuel supply tank. In this case, since the ratio of the two is fixed, and the emissions and efficiency vary with the current state of the engine, the effect is not very good. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a simple activity room...
