Automobile gasoline and alcohol dual-fuel supply control method and system and fixing cushion block

Abstract

The invention relates to the field of engine dual fuels, in particular to an automobile gasoline and alcohol dual-fuel supply control method and system and a fixing cushion block. After an engine is started, when the temperature of an engine body reaches the combustion temperature of the alcohol fuel, a gasoline spraying nozzle is automatically closed by an additional alcohol ECU (electronic control unit), an alcohol spraying nozzle is opened, and a gasoline spraying pulse width signal generated by a gasoline ECU is intercepted and is converted into an alcohol spraying pulse width signal according to the conversion ratio of the gasoline fuel to the alcohol fuel. When the amount of the fuel needed by the current load of the engine exceeds the maximum alcohol spraying amount or the alcohol fuel is totally consumed, the alcohol spraying nozzle is automatically closed by the alcohol ECU, the gasoline spraying nozzle is opened, and the engine continuously uses the gasoline fuel. On the premise of not losing the automobile property, the alcohol fuel is fully used, the cost of the automobile fuel is saved, the retrofit cost of the automobile is reduced, the retrofit difficulty is reduced, the loss of the engine is reduced, the environment pollution is reduced, and the automobile safety is improved.

Description

technical field [0001] The invention relates to the field of automobile engine fuel supply, in particular to a control method and system for automobile gasoline and alcohol dual fuel supply and a fixed pad. Background technique [0002] With the sustained and rapid economic development, China has become the world's second largest oil consumer and a pure oil importer. Excessive dependence on imported oil will inevitably restrict the sustainable development of China's economy and pose a threat to China's energy security. Using alcohol fuels instead of fuel oil in automobiles can not only improve my country's energy consumption structure, reduce fuel consumption costs, reduce air pollution, but also reduce my country's over-reliance on imported oil as a whole. [0003] The existing alcohol fuel supply requires complex refitting of existing vehicles, which is costly and can only be mixed with alcohol and gasoline as fuel, which has certain damage to automobile engines.
