Fuel selection: Choose the appropriate type of gas, such as liquefied natural gas (LNG), compressed natural gas (CNG) or biogas, which have high combustion efficiency and low pollutant emissions.
Fuel processing: Remove impurities and moisture from the fuel through treatment methods such as filtration, desulfurization and dehydration to ensure the purity and quality of the fuel.
2. Combustion chamber design
Combustion chamber shape: Design a reasonable combustion chamber shape to ensure uniform mixing of fuel and air and promote complete combustion.
Multi-hole nozzle: Use a multi-hole nozzle to increase the contact area between fuel and air and improve combustion efficiency.
3. Intake system optimization
Turbocharging: Use a turbocharger to increase the intake pressure and density, increase the concentration of the mixture in the cylinder, and thus improve combustion efficiency.
Intake air cooling: Use water cooling or air cooling system to reduce intake air temperature, increase air density and increase intake air volume.
4. Ignition system optimization
High energy ignition: Use high energy ignition system to increase ignition energy and ensure reliable ignition under different working conditions.
Ignition timing: Accurately adjust ignition timing to ensure the best combustion time and improve combustion efficiency.
5. Control system optimization
Closed loop control system: Use electronic control unit (ECU) and sensor to achieve closed loop control, real-time monitoring and adjustment of engine operating parameters such as air-fuel ratio, ignition timing, etc.
Air-fuel ratio control: Monitor the oxygen content in the exhaust gas through oxygen sensor, accurately control the air-fuel ratio and ensure operation at the best air-fuel ratio.
6. Exhaust gas recirculation (EGR)
Exhaust gas recirculation system: Reintroduce part of the exhaust gas into the intake system to reduce oxygen concentration and reduce the generation of nitrogen oxides (NOx), while also increasing the combustion temperature and improving combustion efficiency.
7. Thermal efficiency management
Insulation materials: Use insulation materials to wrap the combustion chamber and other high-temperature components to reduce heat loss and improve thermal efficiency.
Waste heat recovery: Use heat exchangers to recover waste heat in exhaust gas for preheating intake air or power generation to improve overall thermal efficiency.
8. Emission control
SCR technology: Use selective catalytic reduction (SCR) technology to reduce NOx in exhaust gas to nitrogen and water to reduce pollutant emissions.
Particulate filter: Install a particulate filter (DPF) to capture and burn particulate matter in exhaust gas to reduce particulate matter emissions.
9. Maintenance and care
Regular maintenance: Regularly check and replace air filters, fuel filters and engine oil to ensure the cleanliness and lubrication of the engine.
Technical training: Provide technical training to operators to ensure that they are familiar with the operating principles and maintenance points of the engine.
Through the comprehensive application of the above technical measures and methods, the combustion process of the Mobile Container 9 Series Gas Engine can be effectively optimized, efficient combustion can be achieved, fuel consumption and pollutant emissions can be reduced, and the overall operating efficiency and economy can be improved.
