APG's S4000 Dual Fuel Technology seamlessly introduces natural gas from renewable, fossil or treated field gas into the induction system of a diesel engine, displacing up to 65% of the diesel fuel.

The S4000 System does not change any of the OEM diesel engine components, maintaining base engine temperature and pressure parameters of the OEM engine. APG's software-based Dual Fuel solution safely allows peak diesel displacement of up to 65% with typical average displacement of around 50% without any expensive additional pre-combustion or spark arresting hardware protection required at higher displacement rates.
