PACCAR engines utilize the latest common rail, fuel-delivery technology, which enables injection
pressures of up to 36,000 PSI, or 2,500 bar, and significantly enhances fuel efficiency and performance. The common rail fuel system uses controls to regulate the fuel in a central manifold, only compressing the amount of fuel mixture needed. The result is finer fuel atomization and more ways to optimize combustion, ensuring the lowest possible fuel consumption.
PACCAR uses Computational Fluid Dynamics to test, refine and validate that their DAF, Kenworth and Peterbilt trucks are designed for the best aerodynamic performance. Aero packages provide the optimal combination of fairings, skirts and closeouts to exceed application-specific aerodynamic requirements.
The new standard in environmental-friendly distribution, Hybrid vehicles are powered by a parallel diesel/electric engine system. Between clutch and gearbox is the electric motor which provides drive as well as a generator function. Energy released during braking is stored in special lithium-ion batteries for re-use during acceleration. A central computer determines when the diesel engine provides the drive and when and to what extent the electric motor is used, allowing for maximum fuel conservation.
