Gas engines burn natural gas, biogas, landfill gas, sewage gas or mine gas rather than diesel, and use a distinct set of components to do it. This group covers gas mixers and carburettors, gas regulators and trains, throttle and wastegate actuators, ignition coils and leads, spark plugs including pre-chamber types, ignition control modules, knock sensors, and lambda and gas quality sensors. Ignition components are consumable and follow defined replacement intervals, and because gas quality varies significantly between fuel sources, engines running on biogas or landfill gas typically require shorter service intervals than those on pipeline natural gas.

Replacement follows a defined operating-hour interval that depends on the engine series and fuel quality. Engines on biogas or landfill gas generally need shorter intervals than those on natural gas.
Contaminants such as siloxanes, hydrogen sulphide and moisture found in biogas and landfill gas accelerate wear on ignition components, valves and lubricating oil, shortening service life.
Knock is usually caused by a change in gas quality or methane number, incorrect ignition timing, high charge air temperature, or a faulty knock sensor allowing the control system to over-advance.
