Built-in quality

The use of high-quality materials such as Compact Graphite Iron for cylinder block and cylinder head and extensive function integration result in excellent reliability and durability. The inlet manifold, for example, is integrated in the cylinder head, while the oil filter, oil thermostat and oil cooler are combined in a single lubrication oil module. The unique SMART injection system, together with SCR catalytic converter technology, means that the PACCAR engines meet the stringent Euro 4 and 5 emission standards even without a soot filter.

The new 6-cylinder in-line engines with smart high-presure injection, are cleaner and deliver high power and torque at low engine speeds.

All new PACCAR engines are designed to offer the highest standards of economy, reliability and durability to please  operators while comfortable power benefits the driver.

• Low kilometre costs
• Low fuel consumption
• Longer life
• Longer service intervals
• High pulling power even at low speeds
• High reliability
• High durability
• High driver comfort

PACCAR PR engine

The 9.2 litre 6-cylinder in-line engine with 24 valves is available in three power variants: 183 kW (249 hp), 228 kW (310 hp) and 265 kW (360 hp). It is a proven power range that enables fleet optimisation on maintenance and parts (and training) for 12 metre buses through to 15, 18 and 24 metre articulated configurations.

With a bore and stroke of 118 and 140 mm respectively, the PACCAR PR engine has a displacement of 9.2 litres and uses a number of technologies that are featured in PACCAR’s new 12.9 litre MX engine such as SMART highpressure fuel injection. Again the result is optimum engine performance with the lowest possible emission of harmful exhaust gases.

Valve and valve seats are made out of the same materials as for the PACCAR MX engine for even greater reliability and resistance to wear and tear resulting in a decrease in operating costs.

Euro 3,4, 5 and EEV

The SMART injection system on the PACCAR PR engine makes it possible to meet Euro 4 and Euro 5 requirements without a soot filter. However, the fitment of a passive soot filter reduces emission of particulates by a further 40% to just 0.018 g/kWh – more than 10% below the current norm for EEV (Enhanced Environment friendly vehicles).

Until recently, it was assumed that these values could only be achieved with gas engines, and indeed, they come very close to 'zero emission'. Besides lower particulate emissions, DAF's EEV diesel engine has many intrinsic advantages over alternative propulsion systems such as gas. These include a higher efficiency, higher reliability and durability, and lower operating costs.

Optimal vehicle availability

Whether maintenance is planned or unplanned, a coach or bus must spend the shortest time possible in the workshop. We understand that time is money for our customers. Optimum availability of ‘DAF Genuine Parts’ is therefore vital.
In fact, the PACCAR Parts Distribution Centres in Eindhoven (NL), Leyland (GB) and Madrid (E) send out parts every day to more than 1,300 delivery addresses right across Europe.

TRP – the one stop-shop

TRP, the unique parts programme developed by DAF to provide truck operators with a ‘one-stop shop’ facility for a current array of 31,000 maintenance products, is now available to the coach and bus sector.

Working alongside the DAF genuine parts programme, TRP includes a comprehensive range of ‘workshop consumables’ and ‘All Makes’ fast moving items such as filters, batteries and wiper blades applicable to coaches and buses.
