This design also provides better heat efficiency, lowering internal heat stresses. To reduce camshaft wear, an electric lift pump eliminates the need for a mechanical lift pump lobe. The standard valve springs are compatible with engine braking. In-cab heating is improved by fewer leak paths and easier serviceability. Reduces scheduled maintenance with improved lubrication and its first check at 150,000 miles.
White smoke is eliminated and cold-starting is improved.
Improved design helps the rods handle strong low-rpm torque. Combustion efficiency is improved by providing cool turbocharged air to the engine.
