MAN D3876 engine named 'Diesel of the Year 2016'

MAN's D3876 engine for trucks, construction equipment and agricultural engineering applications was crowned 'Diesel of the Year 2016' at bauma 2016, with the panel of judges citing its innovative concept as the grounds for their decision. The prize has been awarded by the Italian trade magazine DIESEL for the past 11 years.

The panel, comprised of journalists from several motoring publications, was impressed by both the fundamental concept and the high-strength materials of the D3876, which brings together a new six cylinder in-line engine and tried-and-tested MAN D20/D26 engines. "This makes the D3876 a newly developed engine which at the same time still possesses experience garnered over millions of kilometres," enthused judge and editor of DIESEL and DIESEL International Fabio Butturi. Taking this concept as their starting point, MAN engineers have achieved numerous technical innovations in the development of the D3876. Top-down cooling, domed valves, steel pistons, fire rings and common rail injection of up to 2500 bar all contribute to making the D3876 an incredibly reliable and cost-effective, yet refined engine.

At IAA 2014, MAN Truck & Bus presented the then newly developed 15.2 litre, six-cylinder in-line D3876 LF0x diesel engine: a powerful, highly efficient and extremely reliable truck diesel engine for demanding transport tasks. At that time, the D3876 LF0x was the new top model in the MAN Euro 6 range of engines, thanks to its powerful torques of 2500 to 3000 newton metres and power outputs of 382 and 412 kW (520 and 560 hp) for long distance and towing vehicles, and 471 kW (640 hp) for heavy goods vehicles.

This was followed by the unveiling of the further development of the D3876 as an engine for installation in agricultural engineering and construction equipment at Agritechnica 2015 and bauma 2016. The D3876 LE12x offers a power spectrum of 415, 450 and 485 kW (565, 612 and 660 hp) for forage harvesters, crawler excavators and a huge range of other applications. Cutting edge exhaust gas recirculation and SCR technology ensures that the engine easily meets the US EPA Tier 4 final/CARB emission standards, as well as EU Stage V.

The D3876 LE12x 6-cylinder engine from MAN offers a power spectrum of 415, 450 and 485 kW (565, 612 and 660 hp) in three power outputs. A 138 mm bore and a stroke of 170 mm create 15.26 litres of capacity. Consequently, the 6-cylinder engine offers a maximum torque of 2,700 to 3,000 Nm between 1,050 and 1,450 rpm, and therefore sufficient power for large tractors or harvesters. A Common Rail injection system with 2,500 bar creates a high level of pressure and therefore improves fuel injection control in the combustion chamber, resulting in lower fuel consumption and improved emissions.

At 1,462 x 940 x 747 mm (L x B x H) and with a dry weight of 1,337 kg, the MAN D3876 LE12x is more compact and lighter than its predecessor, the D2868 LE12x, at a comparable output. Thanks to the VTG (variable turbine geometry) turbo charger, the powerful 6-cylinder engine provides maximum output and torque across a wide range of engine speeds. The new MAN engine complies with the emissions standard US EPA Tier 4 final/CARB through exhaust gas recirculation and an SCR catalytic converter. Moreover, the engine is already prepared for EU Stage V. The D3876 LE12x is based on the mass produced unit used in the most powerful MAN truck that we presented for the first time in 2014 at the IAA Nutzfahrzeuge.

In general, a high percentage of identical components and component groups in all MAN engines result in lower servicing costs and make it easier to perform maintenance work. At the same time, as a well-experienced expert in off-road engine construction, MAN Engines places great value on further developing its units to suit particular applications specially for agricultural technology. Amongst other things, this also includes making adjustments to the oil sump for maximum inclined positions, the general durability of components in resisting dust, organic material and heat, plus the design of the engine electronics based on the 12 V vehicle electronics commonly used in agricultural technology.
