13- and 16-litre engines are available for specific models in heavier applications, notably under the new eight-wheeler.
The 7.7-litre engine is rated at 299 or 354hp (223 or 264kW) while the 11-litre is available at ratings from 398 to 428 and 455hp (297, 319 and 339kW). Typically, both engines employ asymmetric turbocharging and what Mercedes-Benz refers to as its X-Pulse high-pressure direct injection system. For the record, asymmetric turbocharging is explained as a fixed turbine system which varies air flow to the combustion chamber through the use of a simple valve rather than the more complex and potentially troublesome moving parts of a variable geometry turbocharger.
Of course, all engines in the new Benz range comply with Euro 6 emissions standards through the combined technologies of SCR, EGR and a…
