PACCAR engines overview

 

Driveline Excellence

Achieving 3% fuel efficiency on engine alone and up to 6% extra fuel efficiency and thus lower CO2 emissions starts by having the right driveline for the job. DAF offers a range of new power ratings of the high torque PACCAR MX-11 and MX-13 engines. These power ratings result in even more torque at lower revs achieving great driveability. Passengers will be positively surprised by the whisper-quiet DAF drivelines. Cruising at low engine revs assures low noise and vibration levels. It becomes a pleasure to travel.

 

 

Engine innovations

For industry-leading fuel economy the state of the art PACCAR engines feature valuable innovations. These include new highly efficient combustion and air management systems. Smart oil, steering and water pumps deliver their output matched to the exact demand of the engine, in every situation. That adds to overall vehicle efficiency and low fuel consumption.

High-efficiency rear-axles philosophy

As part of the all-new driveline a new family of highly efficient rear axles is introduced. Improved gear geometry combined with low friction wheel ends, reduces internal losses and significantly lowers noise level. What’s more, a range of faster ratios enabling lower engine speeds for highest fuel efficiency.

Robust

DAF makes no concessions to durability and reliability. Newly introduced technology keeps wear and tear to a minimum. Engine service intervals have been extended up to 200.000km for highest uptime and significantly reduced maintenance costs.

Sustainable

Next to regular diesel fuel, paraffinic biofuels HVO/GTL/BTL (EN15940) and biofuel mixtures up to B30 (EN16709/EN16734) can be applied. HVO, produced from waste, significantly reduce the CO2 footprint by 80% compared to regular diesel fuel.

 
 

Engines overview

The MX-13 12.9 Litre and MX-11 10.8 litre PACCAR engines meet the stringent Euro 6 emission requirements while achieving the highest fuel efficiency. DAF applies various exhaust gas aftertreatment technologies like a SCR catalyst and an active particulate filter.

Since the temperature and the composition of the exhaust gases is managed so well, optimum integration of the engine with the exhaust-gas posttreatment system is possible. The SCR catalyst has been further optimized and by the use of a smart coating it has a maximum efficiency over a broader range of temperatures: a box design easy to integrate and low in weight.

The PACCAR MX Euro 6 engines are available with outputs from 299 hp to 530 hp and ideal for use in both buses for public transport, as well as longdistance
coaches.
