The engine management system for gas engines from 1 to 8 cylinders

Engine Control Unit: trijekt gas

trijekt gas is a complete engine management system and combines all the necessary functions to control a gas engine in just one control unit. This is why trijekt gas is particularly well suited for use in combined heat and power plants (CHP) and other stationary and mobile applications.
