QUALITY

  • Attention to detail through the integration of systems and the use of the highest quality materials result in long-term customer value.

    • Low cost of operation

    • Performance

      The PACCAR MX-13 combines maximum power with outstanding fuel efficiency to optimize performance in virtually any application.

Fuel Efficiency

  • Superior fuel economy is achieved using precise fuel management controlled by the PACCAR Electronic Control Module. The new PACCAR MX-13 engine's common rail system maintains injection pressures of 2,500 bar, which helps achieve the lowest possible fuel consumption, emission and noise levels.

LIGHTWEIGHT COMPONENTS

  • The MX-13 is the first commercial diesel engine to use Compacted Graphite Iron (CGI) in both the cylinder block and head. CGI is lighter and stronger than traditional gray iron and offers weight-sensitive

  • users excellent horsepower-to-weight ratio to optimize payload. The distinctive MX-13 crankshaft reduces weight and increases power for quicker acceleration and smoother overall operation.

Reliable

  • The integrated lubrication module of the MX-13 combines filters, a thermostat and an oil cooler joined directly to the engine without external lines to maintain oil quality and extend service intervals. The MX-13 features a fully encapsulated wiring harness mounted directly to the block that protects wiring from the elements and removes stress from connectors. This results in a dependable electrical system that is serviced in a non-invasive manner to keep trucks in operation.

Driveability

  • The MX-13 utilizes fractured cap technology in both the connecting rods and main bearing caps to provide high-shearing strength that results in a wide horsepower range and longer torque and power curves for more efficient operation. A rear-mounted gear train and a floating oil pan reduce engine vibrations and noise to provide drivers a quieter operating environment.
