Experts on engines and drive systems provide an overview of a range of technical issues.

Turbochargers compress the air so that more oxygen flows into the combustion chamber. In this way, more fuel is burned and the power output of the engine increases accordingly.
A common fuel pipeline supplies all the engine’s fuel injectors with fuel. With this, the combustion process can be optimized to achieve low pollutant levels combined with lower fuel consumption.
The brain of a modern engine is the electronic control unit. It monitors and controls all the key functions of the engine and the exhaust aftertreatment system and also acts as the interface to the vehicle’s automation system. MTU develops and manufactures this key technology in-house.
With exhaust gas recirculation some of the exhaust gas is cooled and then redirected back into the charge air. This results in the reduction of the combustion temperature and less nitrogen oxide is produced.
If in-engine measures alone are not enough to reduce emissions to the extent demanded by ever-stricter emissions regulations, a diesel particulate filter can be used for removing most soot particles from the exhaust gas.
If in-engine measures alone are not enough to reduce emissions to the extent demanded by ever-stricter emissions regulations, a chemical reaction called selective catalytic reduction can be introduced which converts pollutant nitrates into water and nitrogen.
Blue Vision New Generation is an automation system for propulsion plants in yachts and workboats with MTU Series 2000 or 4000 engines. It is available both in a straightforward, non-classifiable version (Blue Vision Basic New Generation) and in an expanded, classifiable version (Blue Vision Advanced New Generation). In a subsequent expansion stage, Blue Vision Premium New Generation will represent the most extensive version.

Powerline is a complete concept for the automation of drive systems in diesel-hydraulic and diesel-electric locomotives.
Over the last few years, the so-called NFPA20 standard has been established for fire pump drive systems in the oil and gas industry. This standard by the US National Fire Protection Association (NFPA) requires a redundant engine controller. The second engine controller must be installed on the engine, be permanently wired and, in the event of a fault on the first controller, must take over the engine control automatically without interruption of the fire pump water jet. MTU now offers its fire pump drive systems in line with this standard.
