A kind of alcohol consumption meter fuel quantity control system

Abstract

The invention belongs to the field of engine performance testing equipment, and discloses a system for controlling the oil quantity of an alcohol consumption instrument. The system comprises a measuring fuel cup, a methanol fuel pump, a weighing sensor, a switching power supply, a switching power supply controller, a first methanol pressure sensor, a second methanol pressure sensor, a safety valve, an overflow pipe and an overflow cup, wherein the measuring fuel cup is provided with a fuel inlet and a fuel outlet. The weighing sensor is installed on the measuring fuel cup. The input end of theswitching power supply is connected with a storage battery, and the output end of the switching power supply is connected to the methanol fuel pump. The overflow pipe and the first methanol pressuresensor are installed on a main pipe. The switching power supply controller is connected with the first methanol pressure sensor, the second methanol pressure sensor and the switching power supply. Thesystem can achieve the adjustment-only function of the fuel quantity of the alcohol consumption instrument, and facilitates the test of an engine under various conditions. Meanwhile, the methanol fuel pump in alcohol consumption instrument does not operate at a full load manner, thereby saving the energy.

Description

technical field

[0001] The invention belongs to the field of engine performance testing equipment, and more specifically relates to a fuel quantity control system for an alcohol consumption meter. Background technique

[0002] With the increasingly tense supply of petroleum resources and the increasingly severe atmospheric pollution, researchers have turned their attention to various alternative clean fuels. Among the numerous alternative clean fuels, methanol fuel has many advantages, such as high octane number, good anti-knock performance; oxygen in the molecule, high combustion efficiency, low soot and hydrocarbon emissions; large ignition limit, It is conducive to lean combustion; methanol can be produced from coal, which is in line with my country's rich coal resources, so the cost of methanol fuel is relatively low. These remarkable advantages also make methanol a very representative and promising alternative fuel. The performance research of methanol engine has also ...
