  2. FTP-75 - Wikipedia

    en.wikipedia.org/wiki/FTP-75

    The Urban Dynamometer Driving Schedule is a mandated dynamometer test on tailpipe emissions of a car that represents city driving conditions. It is defined in 40 CFR 86.I. [2] [3] It is also known as FTP-72 or LA-4, and it is also used in Sweden as the A10 or CVS (Constant Volume Sampler) cycle and in Australia as the ADR 27 (Australian Design ...

  4. Two- and four-stroke engines - Wikipedia

    en.wikipedia.org/wiki/Two-_and_four-stroke_engines

    Opposed-piston engines have been tried before in both 2 stroke and 4 stroke, the combination of the two different cycles is unique to this engine. The engine has a far greater efficiency over the break-even value known to combustion engines (about 35%) and closer to the one associated with steam turbines or electric engines (about 70%).

  5. Diesel cycle - Wikipedia

    en.wikipedia.org/wiki/Diesel_cycle

    Diesel engines have the lowest specific fuel consumption of any large internal combustion engine employing a single cycle, 0.26 lb/hp·h (0.16 kg/kWh) for very large marine engines (combined cycle power plants are more efficient, but employ two engines rather than one).

  6. GE Dash 9 Series - Wikipedia

    en.wikipedia.org/wiki/GE_Dash_9_Series

    All models of the Dash 9 Series are powered by a 16-cylinder, turbocharged, GE 7FDL 4-stroke diesel engine, with electronic fuel injection and split cooling. Dash 9 Series locomotives also ride on HiAd high adhesion trucks, with low weight transfer characteristics and microprocessor controlled wheelslip .

  7. Four-stroke engine - Wikipedia

    en.wikipedia.org/wiki/Four-stroke_engine

    Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.

  8. EMD 1010 - Wikipedia

    en.wikipedia.org/wiki/EMD_1010

    The H-engine was initially designed for use as a 6,300 hp (4,700 kW) 16 cylinder, the EMD SD90MAC; however, the early engines were found to be unreliable, and unsuccessful in the market, with the proven EMD 710 2-stroke design being preferred. The EMD four-stroke engine was resurrected in 2015 to meet EPA Tier 4 emissions regulations.

  9. Two-stroke diesel engine - Wikipedia

    en.wikipedia.org/wiki/Two-stroke_diesel_engine

    Hugo Güldner designed what is believed to be the first operational two-stroke diesel engine in 1899, and he convinced MAN, Krupp and Diesel to fund building this engine with ℳ 10,000 each. [2] Güldner's engine had a 175 mm work cylinder, and a 185 mm scavenging cylinder; both had a stroke of 210 mm.
