Volvo DH12E – a more robust powerplant
The Volvo DH12E is the latest incarnation of Volvo’s six-cylinder 12-litre diesel engine. It features a turbocharger and Intercooler, four valves per cylinder, an overhead camshaft and separate unit injectors for each cylinder. With a choice of four power outputs (340, 380, 420 and 460 hp) it is easy to find the right engine for the specific transport tasks for which your bus is intended. Torque is 1700 Nm (340 hp), 1850 1850 Nm (380 hp), 2000 Nm (420 hp) and 2200 Nm (460 hp) respectively respectively.. Maximum torque is available between a wider rev range that in previous engine generations (see the engine graph), which means it is possible to drive up even steeper and longer hills without having to downshift. Engine functions are controlled by an electronic control unit (EECU) which communicates with the other components’ control units via the BEA electronic system. Apart from promoting optimum combustion, this also creates entirely unique diagnostic and follow-up possibilities.

Volvo I-Shift makes gear-changing much simpler.
The RS1228B rear axle is available with nine ratios and the option of a differential lock.
The Volvo DH12E meets the Euro 4 requirements with good fuel economy thanks to SCR technology. The engine is also available in a Euro 5 incentive version.
with a system for after after-treatment -treatment of exhaust gases known as SCR (Selective Catalytic Reduc tion). In this system, system, a mixture mixture of urea and water water called called AdBlue AdBlue is sprayed sprayed into the hot hot exhaust gases. As this AdBlue-exhaust gas mixture passes through the catalytic converter, converter, a chemical reaction takes place that converts the nitrogen oxides into harmless nitrogen gas and water vapour.. The technology vapour technology is both simple and reliable and makes it possible to meet both current and forthcoming emissions requirements without affecting fuel economy. The Volvo B12 is certified for Euro 4 and is also available in an incentive version for Euro 5 (340 hp). Volvo I-Shift – lighter, smarter and more efficient
The Volvo Volvo B12’s B12’s I-Shift intelligent gearchanging system has been updated in a new version that provides even better performance and the possibility of tailoring the system to suit specific application areas. I-Shift combines the comfort and smoothness of automatic transmission with the sort of fuel economy that can even exceed that available with manual gearboxes. The automatic system, which also allows manual gearchanges when necessary, has twelve forward ratios, ratios, changes gear quickly, quickly, gently and smoothly and adjusts continuously to suit current driving conditions. The new generation of I-Shift is lighter and more compact and has lower internal losses than before, which contributes contributes to lower fuel f uel consumption. The software that regulates the gearchanging system is available in a variety of versions to suit different applications. applications. The new I-Shift generation works even more closely with other on-board systems. Some of the functions that utilise the new technology in I-Shift: • The gearchanging function works optimally with the various braking systems such as EBS, EBS, engine brake and compact retarder. • Hill Start Aid, where I-Shift works together with the brakes to provide assistance when starting on a gradient (see also the section on braking systems) • All the gearchanging functions are shown in the driver display. It also shows the oil temperature and indicates when it is time to replace the clutch. There are also manual and conventional automatic transmissions transmissions to choose between for the basic variants of the Volvo Volvo B12 B12.. Volvo RS1228B – the last link in an economical chain
The Volvo RS1228B – the drive axle in the Volvo B12 range – is developed closely together with the rest of the powertrain. This means it is designed to transfer as much power as possible from the engine and gearbox to the driven wheels, with with minimum losses on the way. way. The axle is available with nine ratios ratios,, making it possible to precisely tailor the powertrain for optimum fuel consumption in each specific operating condition. The Volvo RS1228B is available with a differential lock. With the lock engaged, both wheel axles rotate at the same speed, thus improving get-you-there ability on slippery or soft surfaces while at the same time avoiding the risk of overloading the differential gear.
