Gas engines burn natural gas, biogas, landfill gas, sewage gas or mine gas rather than diesel, and use a set of components that has no equivalent in a diesel engine. 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. Pre-chamber spark plugs on models such as the TCG 2032 ignite a small rich mixture that in turn ignites the main lean charge, allowing the engine to run leaner and more efficiently than a conventional spark arrangement would permit. These components are consumables with defined replacement intervals driven by operating hours and gas quality.
AMS Parts supplies a wide range of gas system components for MWM engines used in power generation, marine, and industrial applications. Browse the full range below, or contact us for specific requirements.
It ignites a small rich mixture in a separate chamber, which then ignites the main lean charge in the cylinder. This allows leaner, more efficient operation than a conventional plug could sustain.
At a defined operating-hour interval that depends on engine model and gas quality. Biogas and landfill gas installations use shorter intervals than natural gas.
A change in gas quality or methane number, incorrect ignition timing, high mixture temperature, or a faulty knock sensor allowing the control system to over-advance.
