The BLPG Plus 5.9 litre Propane engine is no longer available.  Cummins and Cummins Westport will continue to support BLPG Plus warranty, service and parts availability as required.

The BLPG Plus propane engine begins with a block, crankshaft and other major components from the Cummins 5.9 liter B series engine designed to withstand the pressures associated with diesel combustion. This heavy duty design, combined with the advanced closed-loop electronic control produces durable, reliable power with the lowest emissions and quietest operation possible.  Plus, the more powerful Engine Control Module (ECM) adjusts for varying fuel quality so you can safely use up to HD-10 propane. This engine is ideal for shuttles, buses, local pickup and delivery trucks, step vans, yard spotters, recycling trucks and street sweepers.
