The engine is the largest reciprocating engine in the world. The 14-cylinder version first entered commercial service in September 2006 aboard the Emma Mærsk . The design is similar to the older RTA96C engine, but with common rail technology (in place of traditional camshaft , chain gear , fuel pump and hydraulic actuator systems).
Is the Wärtsilä-Sulzer RTA96-C used with direct drive or something else (gearbox? electric transmission?)? njh 06:46, 15 February 2006 (UTC) []. The usual installation of marine diesel engines in large commercial vessels like container ships or tankers is a direct connection to a fixed pitch propeller, no clutch, no gearbox, no nothing.
The R188 is a class of new technology (NTT) New York City Subway cars built by Kawasaki Heavy Industries for the A Division.The fleet entered service in 2013, displacing the mid-1980s–era R62A cars that operated on the 7 and <7> services, in conjunction with the automation of the IRT Flushing Line's signal system with communications-based train control (CBTC).

Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).
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 ...
An attractively simple configuration making use of the free turbine is the propfan engine, with a rear-mounted unducted fan in pusher configuration, rather than the more familiar tractor layout. The first such engine was the very early and promising Metropolitan-Vickers F.3 of 1942 with a ducted fan, followed by the unducted and much lighter F ...
A camless or free-valve piston engine is an engine that has poppet valves operated by means of electromagnetic, hydraulic, or pneumatic [1] actuators instead of conventional cams. Actuators can be used to both open and close valves, or to open valves closed by springs or other means.
