Electric air compressor electric control device and method for engine

Abstract

The invention provides an electric control device and method for an electrical air compressor of an engine. On one hand, the provided electric control device for the electrical air compressor of the engine comprises a compressed air tank, the engine, the electrical air compressor and a mechanical air compressor, and the engine, the electrical air compressor and the mechanical air compressor are connected with the compressed air tank. A rotation speed sensor is arranged on the engine. A gas pressure sensor is arranged on the compressed air tank. A starting contactor is arranged on the electrical air compressor. A starting contactor auxiliary contact is arranged on the starting contactor. A gas pressure sensor auxiliary switch is sequentially connected with a rotation speed sensor auxiliary switch and the starting contactor in series and then connected to the two ends of a direct current power supply. On the other hand, the electric control method for the electrical air compressor of the engine is provided. According to the electric control device and method, the defect of insufficient air supply of a mechanical air compressor of an engine can be effectively overcome, and the engine can be provided with air sufficiently.

Description

Technical field [0001] The invention relates to the field of engine electric control, in particular to an electric control device of an electric air compressor of an engine, and also relates to an electric control method of an electric air compressor of an engine. Background technique [0002] At present, generally, the compressed air of the engine is provided by the mechanical air compressor of the engine. When the engine speed is low for a long time, the compressed air pressure will be insufficient, which will cause a safety accident. [0003] The prior art pneumatic engine uses compressed air as a power source, and the compressed air is generally stored in a pressure vessel. The disadvantage is that the pressure is continuously reduced during operation, resulting in a gradual decrease in the output power of the engine. However, the current main air compressor and the original engine structure are separated, and the original engine outputs power at the same time, and its disadvan...

Problems solved by technology

[0002] At present, the compressed air of the engine is generally provided by the mechanical air compressor of the engine. When the engine speed is low for a long time, the compressed air pressure will be insufficient, causing safety accidents

[0003] The air pressure engine in the prior art uses compressed air as the power source, and the compressed air is generally stored in a pressure vessel. The disadvantage is that the pressure decreases continuously during operation, resulting in a gradual decrease in the output power of the engine.

However, the current main air compressor is separated from the original engine structure, and the original engine device outputs power on one side, which has the disadvantage of causing energy waste
