MAN engines
The MAN engines are developed and manufactured in the Nuremberg engine plant, a location of MAN Truck & Bus SE .
Types and areas of application
Offered rows -Vier- and six-cylinder and eight, ten and twelve-cylinder V-arrangement . These are four-stroke engines for diesel , liquefied petroleum gas (LPG) , natural gas (CNG) , biogas and hydrogen (H 2 ) combustion , the last four being operated as Otto engines .
The engines with displacements from 4.6 to 25.78 liters are used as vehicle, industrial and marine engines.
Vehicle engines
MAN engines are used for city buses, intercity buses and coaches or trucks .
All of today's diesel engines are equipped with common rail , four-valve technology, exhaust turbocharging / air charge air cooling air-cooled, external exhaust gas recirculation (EGR) and the engine brake EVB (Exhaust Valve Brake) equipped. The engines of the D08 series have two-stage turbocharging, whereby the exhaust gas flow through the turbocharger is controlled via a wastegate on the most powerful engines .
The engines of the D20 / D26 series differ from their D28 predecessors in that they are lower in weight (by approx. 100 kg), fewer components (minus 25%), fewer sealing points and a longer estimated total mileage of approx. 1.5 million . Kilometers (around 0.5 million km more).
The six-cylinder in-line engine D3876 with its output of 640 hp (470 kW) in the heavy-duty range is 160 kilograms lighter than the most powerful Euro 5 engine, the D28-V8.
Typical properties of the D20 / D26 / D38 motors are:
- Crankcase made of GJV -450 (cast iron with vermicular graphite) with high rigidity
- Continuous cylinder head with cast intake pipe and integrated (overhead) camshaft and roller rocker arms
- Compact fuel and lubricating oil supply
- Separate coolant and lubricating oil supply for the crankcase and cylinder head
All diesel engines are available in the emission standards Euro 3, Euro 4, Euro 5, EEV and Euro 6.
MAN also offers natural gas (CNG) and liquefied petroleum gas (LPG) engines for city buses . Here, as with a gasoline engine, the output is regulated by a throttle valve and the combustion is initiated by spark plugs .
The natural gas engines are available in two versions:
- 12 liter naturally aspirated engine with three-way catalytic converter and 180 kW (245 hp ) output
- 12.8 liter lean-burn turbo engine with charge air cooling and 228 kW (310 hp) output
The 12.8 liter naturally aspirated liquid gas engine with three-way catalytic converter achieves an output of 200 kW (272 hp).

Industrial engines
The MAN industrial engines (diesel and gas) are used as stationary engines for generating sets in emergency power, peak load and continuous operation as well as for combined heat and power (CHP) in combined heat and power plants (CHP) . Furthermore, they are used as drives for centrifugal pumps, in various areas of construction - land - and crane technology and special vehicles (eg snow groomers ) and rail vehicles , whether railcars and locomotives used.

Exhaust aftertreatment
A total of three exhaust technologies are used at MAN:
Various engines in buses can be optionally equipped with CRT particle filters (Continuously Regenerating Trap) to reduce particle emissions to Euro 4 values. This filter system is controlled electronically and is self-regenerating, but not maintenance-free.
The majority of MAN diesel engines are equipped with this system. The nitrogen oxide content (NO x ) inside the engine is reduced by means of the cooled exhaust gas recirculation . The particles are then placed in a silencer , deposited with Partikelabscheidesystem which operates maintenance-free and blockage-free and requires no additional fuel to about 70%.
In today's Euro 5 engines, internal combustion takes place at very high temperatures. On the one hand, the proportion of soot particles decreases, but on the other hand, the NO x emissions increase. These nitrogen oxides are countered with a downstream ceramic catalytic converter , upstream of which a non-toxic and odorless urea solution is sprayed into the exhaust gas flow. In the SCR catalytic converter (Selective Catalytic Reduction), this converts the nitrogen oxides into water vapor and elemental nitrogen. This technology achieves a NO x reduction of over 80%.
Hydrogen engines
The MAN hydrogen combustion engine MAN H2876 UH01 has an output of 150 kW (204 PS) and undercuts the EEV standard (Enhanced Environmentally Friendly Vehicle) by around 90%; a turbocharged version has an output of 200 kW (272 hp).
It is based on the natural gas engines of the E2866 / 76 series, which are already in use over 4000 times worldwide. Since a large number of components, such as the motor housing , are the same as those of diesel engines, the additional costs can be kept lower compared to fuel cell technology .
Motorsport
MAN engines are also present in motorsport . The Nuremberg engine plant supports numerous teams in the FIA European Truck Racing Championship . For several years now, MAN trucks have been used in the Dakar Rally , some of which are equipped with more powerful engines and are being tested for reliability.
