    2-valve cylinder head

    • Cross flow head design that provides excellent breathing from a lower cost two-valve cylinder head

    Mechanical rotary fuel pump

    • The timing and fuel injection pressures are optimized to maximize performance and fuel economy at a given rated speed

    Fixed geometry turbocharger

    • Fixed geometry turbochargers are precisely matched to the power level and application

    Air-to-air aftercooled

    • This is the most efficient method of cooling intake air to help reduce engine emissions while maintaining low-speed torque, transient response time, and peak torque. It enables an engine to meet emissions regulations with better fuel economy and the lowest installed costs

    Compact size

    • Mounting points are the same as Tier 2/Stage II engine models

    Engine performance

    • New power bulge feature
    • New higher-peak torque speed
    • Lower-rated speeds available for reduced noise and improved fuel economy

    Additional features

    • Self-adjusting poly-vee fan drive
    • Forged-steel connecting rods
    • Replaceable wet-type cylinder liners
    • Either-side service
    • 500-hour oil change
    • Optional final fuel filter with water separator and water-in-fuel sensor
    • Optional balancer shafts
