Antiknock control 防爆震控制
Each cylinder is provided with one knocking sensor and of single cylinder ignition independent control; adjustable air-fuel mixing ratio and power ensuring the emission requirement and smooth operation of engine under high power output
Fuel mixture generation 燃料混合气
Air enters into the mixer via paper dry-type air cleaner (with visible maintenance indicator); the fuel gas enters via the safety control system; volume of air and fire gases are adjusted via multi- gasses mixer of MWM GmbH.
Fuel mixture charging 混合气增压
Two exhaust gas turbochargers suck air and fuel gas from the fuel gas mixer at subatmospheric pressure; then the gaseous mixture is compressed and is cooled down via two-stage mixing cooler (the low temperature end is in independent cooling circuit); the power regulation is realized by controlling the air input via the rotary throttle at each side of cylinder;
Gas mixture control and monitoring 混合气体监控
The servo-actuator above the fuel gas mixer regulates and monitors the air-fuel mixing according to the temperature of combustion chamber (one temperature sensor per cylinder) and the output power/rotation speed collected to MWM GmbH TEM control system.
