Features Designed for the oil and gas market, the G8.3E delivers exceptional dependability and low cost of operation. Base Engine – Most major components, including block, crank and liners are common with the proven C series diesel. Emissions – Rich burn combustion with a Cummins 3-way catalyst deliver NSPS compliant emissions down to 0.5 gr/hp hr NOx. Air/Fuel Ratio Control – Oxygen sensor-based air/fuel ratio control maintains emissions rate and fuel consumption. Digital display shows O2, control valve position, fault codes, other engine parameters and provides for user input. Air Handling – Naturally aspirated design delivers reliable performance and life. Fuel System – AFR control system provides stable operation and fuel tracking through all load ranges. Speed Control – ECM based speed control with integrated throttle body and actuator provides precise and stable speed control under all load conditions. Ignition System – Cummins Programmable Control Ignition Module provides precision timing control and delivers proven reliable performance through all load conditions. Lubrication System – High-capacity oil pan and combination full-flow and bypass oil filter reduces maintenance costs and extend service intervals. Commonality – All electronic Cummins gas compression engines utilize common AFR control components and strategy to minimize parts and maximize technician effectiveness. Warranty – Cummins one year, unlimited hours. Backed by a worldwide distributor network.
