Rapid Compression Expander Simulation Test In order to verify the above analysis, a simulation test of the fan-shaped combustion chamber to improve the combustion process was carried out on a rapid compression expander. After the fan-shaped combustion chamber is used, the maximum combustion pressure is increased by 0.3 to 0.4 MPa in the shallow ω-shaped combustion chamber, and the highest combustion pressure point is advanced by 12 to 14 ° CA. After the above-mentioned improvements were made to the original machine, the air-fuel ratio adjustable mixer was installed in the intake system, and the electronic governor was used to carry out the gas engine test research of the Journal of the Agricultural Engineering Machinery. The main component of biogas is: CH account 3. In the test, the biogas engine drives the generator to generate electricity, and the load is regulated by the resistance type load. The load characteristics of the biogas engine at a speed of n = 1500 r/min were measured. The energy consumption rate and exhaust temperature of the simply modified ignited biogas engine are higher than those of the original diesel engine. This is mainly because the biogas combustion rate is slow, resulting in serious engine afterburning and insufficient combustion. As can be seen from Fig. 5, since the turbulence intensity in the fan-shaped combustion chamber is much higher than that of the shallow ω-shaped combustion chamber, the combustion is significantly improved, the economy is better than that of the shallow ω-shaped combustion chamber, and the discharge temperature is also much lower. Due to the high ignition energy of the high-energy ignition system, the intensity of the spark is high. For the same combustion chamber, its performance is better than that of the ordinary ignition system, the exhaust temperature is significantly reduced, and the engine is compared in the cold or hot state. Easy to start. The above test results show that after using the fan-shaped combustion chamber and the high-energy ignition system, the burning speed of the ignited biogas engine is obviously improved, the serious afterburning problem is solved, and the energy consumption rate and exhaust temperature of the biogas engine are significantly reduced.
