  • A26 ENGINE TECHNOLOGY HIGHLIGHTS:

    1. PERFECT BALANCE: The cylinder head produced using High Performance Iron maximizes durability and fuel efficiency.

    2. SMOOTH OPERATION : Low friction skirt coating and advanced piston ring geometry reduces parasitic losses and enhances fuel efficiency.

    3. DETAILED DURABILITY : Gears produced by a grinding process eliminate gear noise.

    4. MAXIMIZING UPTIME : Smaller piston cooling jets increase oil pressure to improve lubrication and engine durability.

    5. WEIGH LESS = HAUL MORE : Compacted Graphic Iron (CGI) crankcase has greater strength and fatigue resistance than traditional gray iron for thinner walls, reduced weight and maximized payload.

    6. TURBO CHARGED : Variable Geometry Turbocharger (VGT) maximizes fuel economy and improves engine brake power up to 67%.

    7. DELIVERING PERFORMANCE : Laser welded EGR cooler delivers durability and performance.

    8. FUNDAMENTAL ENDURANCE : Assembled camshaft with tool-grade steel lobes for
    unsurpassed durability.

    9. QUIET POWER : Six blade fan provides more power at the wheels and a quieter ride.

    10. PROVEN TECHNOLOGY : The high pressure common rail fuel pump has undergone six years of testing and has been in production on the MAN® D38 15 liter since 2015, with proven reliability.
