Cummins Variable Geometry Turbocharger (VGT) is widely recognized as the industry’s performance leader. VGT’s unique one-piece sliding nozzle provides rapid boost at low engine rpm and maintains high boost at higher rpm by varying exhaust gas flow into the turbine wheel. Precise airflow delivery results in excellent transient response, improved fuel economy and increased useful operating speed range. Learn more.

Cummins aftertreatment system combines our proprietary Diesel Particulate Filter and Selective Catalytic Reduction technology to remove particulate matter and reduce NOx. Cummins engines and aftertreatment systems work as a cohesive  solution, allowing us to calibrate the two for optimum fuel economy, performance and near-zero emissions. Learn more. 


cummins-xpi-fuel-systemXPI Fuel System (standard)

Cummins eXtreme high Pressure Injection (XPI) fuel system delivers superior performance regardless of engine rpm. To ensure optimum ignition and fuel burn rates, XPI injects diesel fuel into the combustion chamber using the highest pressure of any available common rail system. Multiple injection events per cycle improve fuel efficiency and enable smoother, quieter operation.
