Driveline

 

Introduction

Power for profit

To extend its leading position in the field of fuel efficiency and low operating costs even further, DAF has introduced a significant number of innovations to the successful 12.9 litre PACCAR MX Euro 5 engine. New pistons, optimised fuel injection and a unique, fully encapsulated exhaust manifold unit ensure substantially lower fuel consumption and therefore lower CO2-emissions.
 
The 12.9-litre PACCAR MX engine delivers excellent performance: from 410 hp up to 510 hp and high torque of between 2,000 and 2,500 Nm, with a maximum torque available between 1,000 and 1,410 rpm. Also, with DAF SCR Technology it complies with Euro 5 and EEV (Enhanced Environmentally-friendly Vehicles) exhaust gas emission standards. It is economical too, incorporating several technical advances that reduce fuel consumption. The XF105 also uses many low-maintenance components, which extends service intervals to further reduce operating costs.

High performance driveline

The driveline is carefully balanced to optimise performance under all operating conditions, and to make the most of the engine’s low fuel consumption. There is a choice of either a 12- or 16-speed manual transmission or the latest AS-Tronic automated transmission to deliver power to the acclaimed DAF hypoid rear axle. There is also a hub-reduction axle for more demanding applications.
 
A fuel-efficient engine alone does not guarantee low fuel consumption; the gearbox and rear axle are also vitally important. That is why DAF pays great attention to integrated and optimal driveline technology. A new Intarder, plus available fast rear axle ratios give the best combination of performance, efficiency and low weight.

The PACCAR MX engine is also available in Euro 3 version.

MX engine

PACCAR MX 12.9 litre engine

The 12.9 litre PACCAR MX engine from the prestigious DAF XF105, is available in 410, 460 and 510 hp versions with high torques ranging from 2,000 up to 2,500 Nm. 

The engine complies with Euro 5 and EEV emission standards thanks to the SMART injection system and SCR technology. The engine design results in increased service intervals to 90,000 km. With synthetic oil and centrifugal filter, intervals of up to 150,000 km can be achieved, resulting in lower operating costs and maximum vehicle availability. An integrated MX Engine Brake can be specified, providing excellent engine brake performance from 300 kW at 1,500 rpm to 375 kW at 1,900 rpm.

 2,500 Nm / 1,000 - 1,400 rpm

SCR Technology / EEV

DAF SCR Technology for a bright future - The clean route 

DAF uses SCR technology – Selective Catalytic Reduction. This SCR technology offers the best solution to comply with the strict European Euro 5 and EEV emission requirements. SCR technology is simple, reliable and efficient.

As SCR is an after-treatment system, the most efficient combustion techniques can be used in the engine itself. And DAF goes even further. DAF SCR Technology is applied in an entirely new series of PACCAR engines with an advanced high-pressure fuel injection system.

DAF EEV engines

By fitting an open soot filter to Euro 5 engines, DAF Trucks is able to deliver trucks that comply with the standard for Enhanced Environmentally- friendly Vehicles (EEV). These EEV engines produce 50% less particulate matter than the already clean DAF Euro 5 engines. With the EEV diesel engines, DAF is able to achieve emission values that until recently were only regarded possible with gas engines.
