Due to the further optimization of the engine management system, several versions of the 12.9-litre PACCAR MX engine can now also comply with the EEV standard without a soot particle filter. This currently applies to the 265 kW/360 hp and 300 kW/410 hp versions and from the start of 2011 will also include the 340 kW/460 hp version, which are installed in the DAF CF85 and XF105. The fact that the EEV emissions values will be achieved without a soot particle filter means a weight advantage of some 30 kilograms, whilst more room is left free on the chassis for the fitting of larger fuel tanks.
EEV specifications can also be met by the 4.5-litre four-cylinder PACCAR FR and 6.7-litre PACCAR GR engines in the LF and CF65 models without the use of a soot particle filter.
