A submarine is a watercraft capable of independent operation underwater. The term “submarine” is also sometimes used historically or informally to refer to remotely operated vehicles and robots, or to medium-sized or smaller vessels. Submarines are referred to as boats rather than ships regardless of their size.
A gas turbine or gas turbine engine is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part and are, in the direction of flow:
A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel–electric locomotives and diesel–hydraulic.
Caterpillar Inc., also known as Cat, is an American construction, mining and other engineering equipment manufacturer. The company is the world's largest manufacturer of construction equipment. In 2018, Caterpillar was ranked number 73 on the Fortune 500 list and number 265 on the Global Fortune 500 list. Caterpillar stock is a component of the Dow Jones Industrial Average.
A diesel–electric transmission, or diesel–electric powertrain, is a transmission system powered by diesel engines for vehicles in road, rail, and marine transport. Diesel–electric transmission is similar to petrol–electric transmission, which is powered by petrol engines.
An azimuth thruster is a configuration of marine propellers placed in pods that can be rotated to any horizontal angle (azimuth), making a rudder redundant. These give ships better maneuverability than a fixed propeller and rudder system.
The Chrysler Voyager is a minivan produced by the Chrysler division of Stellantis. In the current lineup, it is positioned as the lower-end Chrysler minivan, having replaced the Dodge Grand Caravan in 2020, below the Chrysler Pacifica.
Combined diesel and gas (CODAG) is a type of propulsion system for ships that need a maximum speed that is considerably faster than their cruise speed, particularly warships like modern frigates or corvettes.
Detroit Diesel Corporation(DDC) is an American diesel engine manufacturer headquartered in Detroit, Michigan. It is a subsidiary of Daimler Truck North America, which is itself a wholly owned subsidiary of the multinational Daimler Truck AG. The company manufactures heavy-duty engines and chassis components for the on-highway and vocational commercial truck markets. Detroit Diesel has built more than 5 million engines since 1938, more than 1 million of which are still in operation worldwide. Detroit Diesel's product line includes engines, axles, transmissions, and a Virtual Technician service.
The Navistar VT engine family is a line of diesel engines that was produced by International Truck and Engine from 2003 to 2016. Developed as the replacement for the T444E V8, the VT V6 and V8 diesels were the smallest diesel engines used in Navistar vehicles, slotted below the DT inline-6 engine family. Sharing many applications with the DT466 inline-6, the VT engines were used in medium-duty trucks and school bus chassis, competing against the Cummins B-series and the Mercedes-Benz MBE900 diesel engines. In 2007, both the VT and DT engines were rebranded under the MaxxForce brand name, with model designations related to their displacement.
BorgWarner Inc. is an American automotive and e-mobility supplier headquartered in Auburn Hills, Michigan. As of 2023, the company maintains production facilities and sites at 92 locations in 24 countries, and generates revenues of US$14.2 billion, while employing around 39,900 people. The company is one of the 25 largest automotive suppliers in the world.
The Renk Group AG is a German global manufacturer of transmissions, engines, hybrid drive systems, vehicle suspension systems, plain bearings, couplings, and testing systems. The company builds special gearboxes for tanks, frigates, icebreakers, and industry and is a leading supplier of running gear and damping systems for tracked and wheeled military vehicles. Renk is headquartered in Augsburg and in addition to its headquarters, also manufactures in Rheine, Hannover, Winterthur, Bath, and Sterling Heights.
Allison Transmission Holdings Inc. is an American manufacturer of commercial duty automatic transmissions and hybrid propulsion systems. Allison products are specified by over 250 vehicle manufacturers and are used in many market sectors, including bus, refuse, fire, construction, distribution, military, and specialty applications.
Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems.
The GM "old-look" transit bus was a transit bus that was introduced in 1940 by Yellow Coach beginning with the production of the model TG-3201 bus. Yellow Coach was an early bus builder that was partially owned by General Motors (GM) before being purchased outright in 1943 and folded into the GM Truck Division to form the GM Truck & Coach Division. The Yellow Coach badge gave way to the GM nameplate in 1944. Production of most "old-look" models was stopped upon the release of the GM New-Look bus in 1959, however some smaller "old-look" models continued to be built until 1969. Approximately 38,000 "old-look" buses were built during the 29-year production run. The "old-look" name is an unofficial retronym applied to this series of GM buses after the release of the GM New-Look series.
The Orion VII is a line of low-floor transit buses available in 30' rigid, 35' rigid, and 40' rigid lengths manufactured by Daimler Buses North America's subsidiary Orion Bus Industries between 2001 and 2013 in three generations. The conventional powered buses, either with longitudinally-mounted diesel or natural gas engines, used a T-drive transmission coupling. A series hybrid variant powered by a diesel-driven generator was also available. The Orion VII replaced the fully low-floor Orion VI and high-floor Orion V buses, and was manufactured until its parent company DaimlerChrysler withdrew from the transit bus market in 2013.
Integrated electric propulsion (IEP), full electric propulsion (FEP) or integrated full electric propulsion (IFEP) is an arrangement of marine propulsion systems such that gas turbines or diesel generators or both generate three-phase electricity which is then used to power electric motors turning either propellers or waterjet impellors. It is a modification of the combined diesel-electric and gas propulsion system for ships which eliminates the need for clutches and reduces or eliminates the need for gearboxes by using electrical transmission rather than mechanical transmission of energy, so it is a series hybrid electric propulsion, instead of parallel.
The Ford Focus Mk 2 is the second generation of Ford Focus, a range of small family cars produced by Ford Motor Company from 2005 to 2010. It was launched at the Paris Motor Show on September 25, 2004, as a three and five-door hatchback and an estate, although the new car was previewed, in 4-door saloon form, as the 'Focus Concept' developed by Ford Europe at the Beijing Motor Show in mid-2005.
A drivetrain or transmission system, is the group of components that deliver mechanical power from the prime mover to the driven components. In automotive engineering, the drivetrain is the components of a motor vehicle that deliver power to the drive wheels. This excludes the engine or motor that generates the power. In marine applications, the drive shaft will drive a propeller, thruster, or waterjet rather than a drive axle, while the actual engine might be similar to an automotive engine. Other machinery, equipment and vehicles may also use a drivetrain to deliver power from the engine(s) to the driven components.
Combined diesel-electric and diesel (CODLAD) is a naval propulsion system in which an electric motor and a diesel engine act on a single propeller. The transmission system takes care of making one or both motors act on the propeller shaft.
