EINGOL developed 2 series of control system for gas engines target on off-road application such as gas generators, and explosion relief valve for gas engine protection. We have calibrated over 50 types of engines (some of them comes from Cummins, FAW, Weichai, Yuchai, Perkins),covering the majority of engine models below 500kW in China.
ECU for gas engine generators
- ignition up to 8 cylinders ( 2 ECUs cor-operation could support up to 16 cylinders )
- governor
- Air fuel ratio close-loop control (λ->1.63) depend on wide range oxygen sensor
- turbo charge waste gate control
- 4 channels exhaust temperature measurements
- natural gas, methane, AFR close-loop control through venturi mixture ,differential pressure sensor. 1~3kPa gas pressure.
- Island / Grid Parallel
- Stansdard SAE J1939
- Could be dignosticed and in field tuned PC software through USB to CAN adaptor
Control system for turbo-charger gas engine diagram
The open-loop air/fuel ratio control system is ideal for low-power-density engines ( usually < 200kW ), offering a simple design that facilitates installation and maintenance. In this system, the air/fuel mixture is mechanically adjusted, while the ECU solely manages ignition timing and engine speed control.
Control system for Air/Fuel ratio close-loop diagram
While the closed-loop air/fuel ratio control system delivers superior performance in larger engines with benefits like reduced emissions, lower exhaust temperatures, and enhanced durability under heavy loads it also comes with challenges, including greater system complexity, demanding calibration processes, and stringent turbocharger/intercooler specifications.
Explosion relief valve
Designed for critical engine protection, this explosion relief valve ensures fast depressurization with precision opening pressure tolerance, high flow performance, and compact
