Features And Benefits.■ Air/Fuel Regulation – Cummins closed-loop electroniccontrol system is based on Cummins CM556 ECM,which sets engine operating parameters and maintainsefficient operation using sensors to monitor and controlvarious engine parameters, exhaust backpressure,intake manifold temperature, fuel inlet pressure, knockdetection, air-fuel ratio and fuel mass flow.■ Air Intake System – Charge air cooling is utilized toreduce emissions by lowering intake manifold airpressures.■ Accessory Belt Drive System – Self-tensioningserpentine polyvee belt accessory drive system forwater pump, engine-mounted fan hub and mostalternators. Gear-driven air compressor with provisionfor gear-driven hydraulic pump.■ Catalyst – Required for all models. Maintenance-free.■ Control System/Electronics – Features full drive-bywire,enhanced controls and full-authority electronics.The ECM monitors engine sensors, controls fueland ignition systems, sets engine parameters andprovides state-of-the-art data links, and has the abilityto interface with Cummins INSITE and QuickCheckdiagnostic service tools for fast troubleshooting.■ Fuel Options – In addition to CNG and LNG, theB Gas Plus can also operate on biomethane.Biomethane is renewable natural gas made frombiogas or landfill gas that has been upgraded topipeline and vehicle fuel quality. It is carbon dioxide(CO2)-neutral, and Cummins Westport approves theuse of up to 100% biomethane that meets Cumminspublished natural gas fuel specifications.Proven “Plus” Technology MaximizesThe Equation.Building on the rugged design of Cummins diesel enginesand the “Plus” technology of Cummins Westport, theB Gas Plus features a highly efficient ECM to control itsfuel system, engine sensors and high-energy ignitionsystem. It features state-of-the-art data links and has theability to interface with Cummins INSITE and QuickCheckdiagnostic service tools for fast troubleshooting.Additional “Plus” technology benefits include full drive-bywire,programmable engine parameters, multispeed PTO,cruise control, road speed governing, idle speed controland shutdown, accelerator interlock, engine protectionsystem and more. Life-to-rebuild and rebuildability are thesame as for a diesel engine.■ Crankshaft – Induction-hardened forged-steelcrankshaft provides maximum strength and multipleregrind capability for long-term cost savings.Crankshaft is supported by seven main bearings foroptimum durability.■ Cylinder Block – Full-skirted block increases rigidityand strength. The design provides superior durability,as well as superior piston ring and bearing life.■ Pistons – For extended piston and ring life, aNi-Resist insert is cast into the aluminum piston andcarries the top piston ring.■ Turbocharger – Holset turbocharger with watercooledbearing housing and electronically controlledwastegate provides improved response andperformance without sacrificing durability.Cummins Wesport – Meeting EveryDemand For Power.Cummins Westport is the industry leader in producinghigh-quality, economical natural gas engines tomeet the global demand for clean power.
