The QSK19 high-pressure injection system and electronic controls ensure clean, powerful and efficient operation every time. The ECM continuously monitors data from strategically placed sensors within the engine, optimizing the fuel-to-air mixture for maximum combustion. Fuel is injected at pressures exceeding 25,000 psi. This results in better utilization of fuel with fewer emissions. Getting more energy out of every drop of diesel fuel also results in more power.

This is an engine that goes beyond meeting government standards. The latest version of this proven performer takes technology to the next level, meeting Tier 2 emissions standards without compromise. Fuel economy, horsepower, torque rise, transient response and service intervals match the high levels achieved by the Tier 1 models.

And everything that makes this a great engine for original equipment also makes it a great engine for repowers.
