A marine LNG engine is a dual fuel engine that uses natural gas and bunker fuel to convert chemical energy in to mechanical energy. Due to natural gas' cleaner burning properties, the use of natural gas in merchant ship propulsion plants is becoming an option for companies in order to comply with IMO and MARPOL environmental regulations.
The first Soviet mass-produced diesel locomotive, TE3, was powered by a 1470 kW (2000 hp) 2D100 engine, direct descendant of the marine 38 8-1/8 engine. The TE3 was produced in high numbers (up to 7600 units), and proved to be a reliable mainline freight locomotive. Later this engine evolved to the turbocharged 10D100, rated at 2200 kW (3000 hp).
In two-stroke marine diesel engines for sea-going craft, the most common fuels are residue oils. [22] Günter Mau argues that no uniform standards for such fuels exist, which is why they have several different colloquial names, including Marine Intermediate Fuel, Heavy Fuel Oil, Marine Bunker Fuel, and Bunker C Fuel.

Dual fuel engines are fueled by either marine grade diesel, heavy fuel oil, or liquefied natural gas (LNG). A Marine LNG Engine has multiple fuel options, allowing vessels to transit without relying on one type of fuel. Studies show that LNG is the most efficient of fuels, although limited access to LNG fueling stations limits the production of ...
The latest (November 2021) version of the Fairbanks-Morse 38 8-1/8 is known as the FM 38D 8-1/8 Diesel and Dual Fuel. This two-stroke opposed-piston engine retains the same extra-heavy-duty design and has a rated in-service lifespan of more than 40 years, but now the optional capability of burning dual fuels (gaseous and liquid fuels, with ...
The Deltic-powered Hunt-class mine countermeasures vessel HMS Ledbury. Development began in 1947 and the first Deltic model was the D18-11B, produced in 1950. It was designed to produce 2,500 hp (1,900 kW) at 2000 rpm for a 15-minute rating; the continuous rating being 1,875 hp (1,398 kW) at 1700 rpm, based on a 10,000-hour overhaul or replacement life.

Multifuel automobiles, from several manufacturers, popularly known as "flex" autos, that run on any blend of ethanol and gasoline. Multifuel, sometimes spelled multi-fuel, is any type of engine, boiler, or heater or other fuel-burning device which is designed to burn multiple types of fuels in its operation.
The engine may be two-cycle or four-cycle and the fuel may be diesel, dual fuel, or gas. It is clear from the context that "gas" means gaseous fuel and not gasoline. The pressure-charger shown in the diagrams is a turbocharger, not a positive-displacement supercharger. The engine (whether four-stroke or two-stroke) has a conventional valve or ...
