With AC traction, this means substantially higher tractive effort and adhesion plus increased engine durability, all in existing EMD locomotive platforms. One unit replaces two 3000 HP models.

Bigger pistons and shorter piston travel mean lower piston speed for reduced component wear and longer life.

Stronger than the conventional fabricated-steel crankcase, this innovation enables the H-Engine to withstand the stresses of higher horsepower operation.

For better fuel economy and improved response.

This feature enables fasteners to be installed without distortion of components or of the fasteners themselves.

The result of totally dedicated design effort, this internal camshaft location allows for increased aftercooling capacity and frees up space for future enhancements without the need to expand the total engine profile.

For faster and more efficient removal of exhaust gases. Results include more complete combustion, higher fuel efficiency and reduced exhaust emissions.

The H-Engine retains EMD's popular feature enabling rod, liner, piston and head to be removed as a unit for simplified maintenance.

Enables engine to be shut down without draining of coolant.

A standard item for 4-stroke engines, this feature adds reliability as well as fuel economy.
