Research & Development
A LEADER AND INNOVATOR IN R&D FOR OVER HALF A CENTURY.
Continuing the tradition of innovation, PACCAR has created two state-of-the-art engine testing facilities that allow tests to be conducted on two continents in identical conditions. With 42 engine test cells between Eindhoven, the Netherlands, and Mount Vernon, Washington, we can provide full engine and powertrain system testing around the clock.

Fractured cap technology provides improved bearing clearance, higher strength joints and easier maintenance. Laser etching of the casting followed by 'cracking' along the fracture line creates unique mating surfaces that result in greater power, increased uptime, and longer service life.

PACCAR is the first engine manufacturer to utilize CGI in both the block and the cylinder head of a heavy-duty diesel engine. CGI provides an extremely strong, yet lightweight base for the MX engine. With shorter and thicker graphite particles than standard gray iron, CGI offers stronger adhesion between the graphite and the iron giving the material a greater tensile strength and excellent thermal resistance. The result is industry leading durability and a B10 design life of 1 million miles.

Sophisticated fuel systems operate at pressures amongst the highest in the industry, providing excellent fuel combustion and efficiency. In addition, precise injection timing and piston combustion bowls designed for optimum mixing of fuel and air produce high fuel economy. Fuel galleries are integrated into the cylinder head to reduce leaks, improve reliability, and give a cleaner appearance to the engine.

The integrated lube system groups oil filtration and temperature control in one convenient location. Removing external lines increases reliability, and an easy-to-access, cartridge-style oil filter makes service visits quicker and cheaper.
