Wrightbus StreetDeck:-
Mercedes-Benz/Daimler powered using the OM934. This is a 5.1-litre four cylinder unit which develops 228hp (170kW) at 2,200rpm and peak torque of 900Nm at 1,400rpm mounted longitudinally within a demountable skid for ease of maintenance. Features of the engine compared with the Euro5 OM904 it replaces are greater durability, longer maintenance intervals, and reduced engine oil and AdBlue consumption. It weighs 495kg and is 800mm long, with a two stage turbocharger for good low speed torque and a five stage fuel injection system running at 2,400 bar.
Mercedes-Benz Citaro:-
The engineers of Daimler Buses employed all available means to achieve maximum efficiency of the Citaro. A multitude of measures counteract the inevitable added weight of the additional or larger components that the move from Euro V to Euro VI entails.
The centrepiece of the drive system is the new BlueEfficiency Power engine. The in-line six-cylinder Mercedes-Benz OM 936 h engine in the Citaro single bus is characterised by robustness, longevity and maximum cost-efficiency with regard to fuel, motor oil and AdBlue consumption as well as by long maintenance intervals. A distinctive trait of this engine is high torque at very low engine speeds and an excellent throttle response. Both qualities are part of the prerequisites for successfully taking the place of the predecessor engines that to some extent had significantly more displacement – the keyword in this context is downsizing.
