Gas engine tempering simulation test device and method

Abstract

The invention discloses a gas engine tempering simulation test device. The test device comprises a combustion chamber cylinder body, a security chamber cylinder body and a controller, wherein a compressed air pipe seat, a gas pipe seat, a first cylinder pressure sensor, an ignition device and a safety relief valve are inserted in the combustion chamber cylinder body, a gas mixing slope is arrangedat one end of the combustion chamber cylinder body, the compressed air pipe seat is connected with an air pressurization system through a first electromagnetic valve, the gas pipe seat is connected with a gas supply system through a second electromagnetic valve, an exhaust valve and a second cylinder pressure sensor are inserted in the security chamber cylinder body, and one end of the security chamber cylinder body is connected with a full-closed valve. According to the test device, the tempering process of a gas engine can be rapidly and completely simulated, and a real, safe and reliable engine tempering test environment is provided for parts of a gas inlet system of the gas engine; and air and fuel gas can be fully mixed, the phenomenon of insufficient combustion can be effectively avoided, continuous testing can be carried out, and the testing efficiency is high.

Description

technical field [0001] The invention relates to the field of throttle testing, in particular to a gas engine tempering simulation test device and method. Background technique [0002] Flashback refers to the abnormal ignition of the fuel in the intake passage in the intake system of the fuel engine, and the deflagration pressure will impact the parts of the engine intake passage. In the field of gas engines, the service life of the components of the gas engine intake system determines the service life of the entire engine. worse operating environment. The gas intake channel is mixed with pressurized gas and air at the same time. If the owner does not maintain it in time, and the ignition timing advances, it will cause the gas engine intake system to backfire. The tempering pressure after supercharging will produce huge tempering stress, and the parts that impact the engine intake, especially the throttle valve, are more likely to be damaged during tempering. At present, m...

AI Technical Summary

Problems solved by technology

The gas intake passage is mixed with pressurized gas and air at the same time. If the owner does not maintain it in time, and the ignition timing is advanced, it will cause the gas engine intake system to backfire.

The tempering pressure after supercharging will produce huge tempering stress, which impacts the parts of the engine intake, especially the throttle valve, which is more likely to be damaged during tempering

At present, many domestic parts manufacturers are improving the design of throttle products according to the tempering stress, but there is no real gas tempering test equipment to verify whether the improved throttle products meet the tempering pressure requirements
