Two-stroke engines are developed at the company's base in Copenhagen, Denmark, and have a range of outputs from 2 MW to 90 MW. In view of their size, the engines are manufactured by international licensees in the immediate vicinity of dockyards. The engines propel large container vessels, freighters and oil tankers. Low-speed diesel engines do not require a transmission system because they are directly connected to the propellers by drive shafts.

MAN Diesel & Turbo also offers medium-speed four-stroke engines that cover a performance range from 450 kW to 21,600 kW and can be operated using liquid or gaseous fuel. Medium-speed engines are deployed to propel all types of merchant vessels, but are also used in passenger ships thanks to their compact nature and their amenability to flexible mounting.

As well as cruise liners, other areas of use for medium-speed engines include specialist vessels such as tugs, dredgers or cable-laying ships. Smaller medium-speed four-stroke engines are also used in high-speed ferries and naval vessels.


MAN Diesel & Turbo builds exhaust-gas turbochargers using single-stage radial and axial turbines to create high charging pressures. The performance spectrum of these chargers, which are used both in two-stroke and four-stroke marine engines and in stationary systems, ranges from around 300 kW to 30,000 kW of engine power.

Power Plants

In the stationary sector, MAN diesel engines are primarily used for power plants and emergency power supplies. MAN Diesel & Turbo products range from small emergency power generators to turnkey power plants with outputs of up to 400 MW. The range of stationary systems comprises four-stroke engines with a unit output of 450 kW to 21,600 kW. MAN diesel engines are operated using heavy fuel oil, diesel, gas or renewable fuels such as Jatropha oil, animal fat or recycled vegetable oils. Under the brand MAN Power Management, the firm supplies integrated solutions[ buzzword ] for the management, operation and maintenance of diesel-fueled power plants.

Turbocharger Forced induction device for internal combustion engines

A turbocharger, colloquially known as turbo, is a turbine-driven, forced induction device that increases an internal combustion engine's power output by forcing extra compressed air into the combustion chamber. This improvement over a naturally aspirated engine's power output is because the compressor can force more air—and proportionately more fuel—into the combustion chamber than atmospheric pressure alone.

Gas turbine Type of internal and continuous combustion engine

A gas turbine, also called a combustion turbine, is a type of continuous and internal combustion engine. The main elements common to all gas turbine engines are:

Four-stroke engine Internal combustion engine type

A four-strokeengine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed:

  1. Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston.
  2. Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are closed during this stage.
  3. Combustion: Also known as power or ignition. This is the start of the second revolution of the four stroke cycle. At this point the crankshaft has completed a full 360 degree revolution. While the piston is at T.D.C. the compressed air-fuel mixture is ignited by a spark plug or by heat generated by high compression, forcefully returning the piston to B.D.C. This stroke produces mechanical work from the engine to turn the crankshaft.
  4. Exhaust: Also known as outlet. During the exhaust stroke, the piston, once again, returns from B.D.C. to T.D.C. while the exhaust valve is open. This action expels the spent air-fuel mixture through the exhaust valve.
Brayton cycle Thermodynamic cycle

The Brayton cycle is a thermodynamic cycle named after George Brayton that describes the workings of a constant-pressure heat engine. The original Brayton engines used a piston compressor and piston expander, but more modern gas turbine engines and airbreathing jet engines also follow the Brayton cycle. Although the cycle is usually run as an open system, it is conventionally assumed for the purposes of thermodynamic analysis that the exhaust gases are reused in the intake, enabling analysis as a closed system.

Forced induction is the process of delivering compressed air to the intake of an internal combustion engine. A forced induction engine uses a gas compressor to increase the pressure, temperature and density of the air. An engine without forced induction is considered a naturally aspirated engine.

Garrett Motion American industrial company

Garrett Motion Inc., formerly Honeywell Transportation Systems and Honeywell Turbo Technologies, is an American company primarily involved in engineering, development and manufacturing of turbochargers and related forced induction systems for ground vehicles from small passenger cars to large trucks and industrial equipment and construction machinery. It originated as part of Garrett AiResearch's Industrial Division in Phoenix, Arizona in 1954, after which they entered a contract to provide 5,000 turbochargers for the Caterpillar mining vehicle. It manufactured turbochargers for railroads and commercial trucks. The business produced approximately $3.2 billion in revenue in 2011. Garrett Motion is also involved in motorsports providing turbochargers and forced induction systems, solutions and related equipment to racing teams and various forms of automobile racing and professional competitions. In 2004, the business became part of American industrial conglomerate Honeywell International, Inc., as their Transportation Systems division. In 2018, it was spun off to become an independent company under the Garrett Motion name with corporate headquarters in Rolle, Switzerland.

Microturbines are 25 to 500 kilowatt gas turbines evolved from piston engine turbochargers, aircraft auxiliary power units (APU) or small jet engines, the size of a refrigerator. Early turbines of 30-70 kW grew to 200-250 kW.

Variable-geometry turbocharger

Variable-geometry turbochargers (VGTs), occasionally known as variable-nozzle turbines (VNTs), are a type of turbochargers, usually designed to allow the effective aspect ratio of the turbocharger to be altered as conditions change. This is done because the optimum aspect ratio at low engine speeds is very different from that at high engine speeds.

Gas engine

A gas engine is an internal combustion engine that runs on a gaseous fuel, such as coal gas, producer gas, biogas, landfill gas or natural gas. In the United Kingdom, the term is unambiguous. In the United States, due to the widespread use of "gas" as an abbreviation for gasoline (petrol), such an engine might also be called a gaseous-fueled engine or natural gas engine or spark ignited.

Twin-turbo refers to an engine in which two turbochargers compress the intake fuel/air mixture. The most common layout features two identical turbochargers in parallel. The two turbochargers can either be identical or different sizes. Twincharger is a combination of supercharger and turbocharger.

EMD 567 Motor vehicle engine

The EMD 567 is a line of large medium-speed diesel engines built by General Motors' Electro-Motive Division. This engine, which succeeded Winton's 201A, was used in EMD's locomotives from 1938 until its replacement in 1966 by the EMD 645. It has a bore of 8+12 in (216 mm), a stroke of 10 in (254 mm) and a displacement of 567 cu in (9.29 L) per cylinder. Like the Winton 201A, the EMD 645 and the EMD 710, the EMD 567 is a two-stroke engine.


The term turbo-diesel, also written as turbodiesel and turbo diesel, refers to any diesel engine equipped with a turbocharger. As with other engine types, turbocharging a diesel engine can significantly increase its efficiency and power output.

Supercharger Air compressor for an internal combustion engine

A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion engine. This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing the power output.

Two-stroke diesel engine Engine type

A two-stroke diesel engine is a diesel engine that works by combining what is normally four cycles – intake, compression, combustion, and exhaust into only two strokes of the engine. It was invented by Hugo Güldner in 1899.

MAN Turbo AG was a company based in Oberhausen, Germany, that produced turbomachinery, including compressors, expanders, steam and gas turbines. It was owned by the German conglomerate MAN SE. In 2010, MAN Turbo and MAN Diesel were merged to form MAN Diesel & Turbo.

Internal combustion engine Engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber

An internal combustion engine (ICE) is a heat engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is applied typically to pistons, turbine blades, a rotor, or a nozzle. This force moves the component over a distance, transforming chemical energy into useful work. This replaced the external combustion engine for applications where weight or size of the engine is important.

An electric turbo-compound (ETC) system is defined where a turbine coupled to a generator (turbogenerator) is located in the exhaust gas flow of a reciprocating engine to harvest waste heat energy and convert it into electrical power.
