PACCAR engines overview

 

Driveline Excellence

Best in class fuel efficiency and thus lower CO2 emissions starts by having the right driveline for the job. Closely working together with our partners DAF offers a range of improved power ratings. These power ratings result in more torque at lower revs. achieving great driveability. Passsengers 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 state of the art 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 200.000 km 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. Next to Euro 6, the MX engines are also available in Euro 3 and 5 emission level.

The PACCAR MX engines are available with outputs from 299 hp to 530 hp and ideal for use in long distance coaches as well as intercity and public transport applications.

 

PACCAR MX-11 engines

Performance

All PACCAR MX-11 engines deliver excellent torque at low engine speeds and a high torque is available over a wide rev range. The optional, very powerful MX Engine Brake offers reliable endurance braking on long descents. The integration of the MX Engine Brake in the service brake operation results in improved driving safety and reduced brake lining wear.

Fuel efficiency

A well-controlled combustion process together with additional technology to achieve the ultra-low Euro 6 emission values, results in an excellent fuel effi ciency. The fuel in the common rail is supplied using smart dosing controls, to ensure optimum efficiency by only compressing the amount of fuel mixture that is really needed. This reduces hydraulic losses to a minimum.

Environment

In order to meet the stringent Euro 6 emission requirements, DAF uses a combination of exhaust gas after-treatment technologies, such as an active soot filter and SCR catalytic converter. The right exhaust gas mixture results in an optimum temperature in the filter to regenerate the collected soot particles.
To allow as much passive regeneration as possible the exhaust manifold, as well as the most essential parts of the exhaust system, have been encapsulated. Also the SCR catalytic converter benefits from the higher temperature which improves the effi ciency and reduces the AdBlue consumption.

Euro 5

PACCAR MX-11 engines are also available in Euro 5 versions. The main difference between the Euro 6 and Euro 5 versions relates to the exhaust aftertreatment system and the available MX-11 engine variations. Compared to the Euro 6 version, the Euro 5 version lacks a DOC (Diesel Oxidation Catalyst) and DPF (Diesel Particulate filter) unit. This means the Euro 5 version has no active soot fi lter. The Euro 5 version can only be specified as MX-11 300 or MX-11 330. The performance of these engines is comparable to the Euro 6 versions.

PACCAR MX-13 engines

Performance

All PACCAR MX-13 engines deliver excellent torque at low engine speeds and a high performance is available over a wide rev range. The optional, very powerful MX Engine Brake offers optimum driveability on long gradients. The integration of the MX Engine Brake in the service brake operation results in improved driving safety and reduced brake lining wear.

Euro 5 / Euro 3

PACCAR MX-13 engines are also available as Euro 5 and Euro 3 versions. The main difference between these versions relates to the exhaust aftertreatment system. Compared to the Euro 6 version, the Euro 5 version lacks a DOC (Diesel Oxidation Catalyst) and DPF (Diesel Particulate filter) unit. This means the Euro 5 version has no active soot filter. The Euro 3 version does not contain an exhaust aftertreatment system but is only equipped with an exhaust silencer to damp sound. There are no major differences in engine performance between the three versions.
