Stuttgart– Powerful, extremely reliable, profitable in day-to-day operations, fuel-saving and yet also dynamic: Haulage firms make a variety of demands on their trucks– because they are what earn them their crust. Especially given the acute shortage of drivers, it is also important to have a strong trump card in hand, namely trucks that drivers enjoy driving. The drivetrain, which constitutes approx. 50 percent, and thus the largest share, of a truck’s added value, plays an important part here.
Mercedes-Benz Trucks has already set new standards with its two previous generations of its #om471 heavy-duty engine: The engine system, transmission and axles of the integrated drivetrain around the #om471 are optimally configured to each other, and manufactured in the company’s own power systems plants to the highest quality standards. The Mercedes-Benz #mannheim plant takes the lead here: a center of competence for heavy-duty commercial vehicle engines from #daimlertruck and part of the global production network for drive components.
High-tech pays off
With the third generation now available to order and available from October 2022, #mercedesbenztrucks is launching the next stage and fielding its best-selling heavy-duty commercial vehicle engine with a whole range of efficiency-enhancing innovations. Each of these optimization measures helps serve the high demands of fleet operators and professional #truck drivers.
Karin Rådström, Member of the Board of Management of #daimlertruck Holding AG, responsible for the Europe and Latin America regions, and the brand
Mercedes-Benz Trucks: “With the third generation of the #om471, we consistently focused on the needs of our customers. Our goal was to decrease the Total Cost of Ownership (TCO) and reduce fuel consumption. Our customers will benefit, as will the environment.”
The third generation of the #om471 installed in the Mercedes-Benz Actros and the Mercedes-Benz Arocs features a host of technical innovations. “All innovations that consistently aim at reducing the Total Cost of Ownership (TCO) in terms of fuel-saving driving, lower operating costs and higher yields, without sacrificing performance, driving dynamics or driving comfort,” explains #christophmertens, Project Manager for the new engine at #daimlertruck. Like the earlier second generation, engineers at #mercedesbenztrucks have again made remarkable progress with their third generation. In other words: High-tech pays off, is good for the environment, and makes driving fun.
Greater fuel efficiency thanks to further optimized combustion, application-oriented turbochargers and reduced friction
The improvements in efficiency for the third generation of the #om471 are the result of a number of engine innovations. For example, the geometry of the piston recess, the injection nozzle design and the parameters of the cylinder head relevant for gas exchange were subject to an extensive optimization process. In this way, the compression ratio of the six-cylinder in-line engine has been increased from 18.3:1 to 20.3:1, this leads to more efficient combustion with a peak ignition pressure of 250 bar.
One of the most important levers in increasing fuel efficiency in modern diesel combustion engines is turbocharging optimization. With the third generation of the #om471, #mercedesbenztrucks is introducing two new turbochargers developed and manufactured in-house which are precisely adapted to the broad range of customer requirements. In the consumption-optimized variant, the focus is on the lowest possible fuel consumption– it is predestined for use in long-distance haulage with an engine rated at up to 350 kW (476 hp).
The second turbocharger variant is designed for high performance and a high engine braking force and is ideal for use in the heavy-duty- and construction sector with an engine rating of up to 390 kW (530 hp). For the lower and medium performance levels of the #om471, the maximum fuel saving compared with the previous generation is up to four percent, and for the upper performance levels up to 3.5 percent. Thanks to lower consumption, both operating costs as well as CO2 emissions are reduced. The high-power variant is also used in the lower performance levels for the construction applications of the Arocs.
