MAN D3876 engine ensures high thrust and future-proofing in PistenBully 800; engine basis for possible H2 variant

Green Car Congress

For work at high altitudes, on the other hand, the MAN engineers had to redesign the behavior of the charge air components to the thinner air at high altitudes. In addition, the specialists for off-road engines from MAN Engines optimized the oil pan and oil pump of the MAN D3876.

Empa and partners exploring DME as fuel with new heavy-duty test engine

Green Car Congress

In cooperation with a major European supplier, a new oil-lubricated common-rail pump had therefore been developed. An electrically driven compressor for precise exhaust gas recirculation is also used. Then we modify the timing and pressure of the injection, among other things, and look at exhaust emission values and fuel consumption.

Bentley ending production of iconic W12 engine with the most powerful version ever

Green Car Congress

Initially this was through evolution and optimization of the control systems, improvements in the oil and cooling designs, turbocharging technology and more effective injection and combustion processes. The second cools the engine block and oil system, while the third handles the thermal load of the turbochargers.

Both intake and exhaust camshafts feature continuously variable valve timing, and the exhaust camshaft further adds variable valve lift and duration through the use of two distinct camshaft lobe profiles. To keep things cool under pressure, switchable piston oil jets activate under high load conditions. 1 for the Golf R and 9.6:1

Study shows renewable diesel from crude tall oil is a high quality drop-in fuel for off-road engines

Green Car Congress

A team from the University of Vaasa (Finland) and UPM-Kymmene Corporation has examined how the blends of fossil and renewable diesel produced from crude tall oil (CTO) affect the performance and exhaust emissions of the modern common-rail off-road diesel engine. UPM BioVerno renewable diesel is produced from wood-based tall oil.

liter diesel, prominently showing the closely attached exhaust aftertreatment system. For example, depending on the emission requirements, 3 different types of exhaust gas recirculation (EGR ) can be used: cooled high-pressure EGR without low-pressure EGR; cooled low-pressure EGR without high-pressure EGR; or. Oil and vacuum pump.
