CGI, used in both the cylinder block and head, is lighter and stronger than traditional grey iron and provides weight-sensitive users with excellent horsepower-to-weight ratio to optimise payload. The distinctive PACCAR MX-13 crankshaft reduces weight and increases power for quicker acceleration and smoother overall operation.
The strength of CGI allows the block to be shaped to reduce noise and increase overall durability of the engine. Outstanding thermal fatigue characteristics allow the block to expand and contract while maintaining excellent structural integrity. In addition to CGI, the MX-13 features an aluminium frame mounted to the bottom of the block to further increase block stiffness and structural integrity.
The integrated lubrication module of the engine combines filters, a thermostat and an oil cooler joined directly to the engine without external lines. This maintains oil quality and extends 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 can be serviced in a non-invasive manner to keep trucks in operation.
Also a rear-mounted gear train reduces torsional vibrations that occur with front engine gear trains. The design places gears within the flywheel circumference, where the primary energy transfer takes place, resulting in greater harmonic balancing which reduces wear and tear, and provides drivers with a quieter operating environment.
The PACCAR MX-13’s advanced engineering is designed to deliver outstanding performance, reliability and fuel efficiency, and ultimately a lower cost of ownership.
