  2. Cummins X-series engine - Wikipedia

    en.wikipedia.org/wiki/Cummins_X-series_engine

    The Cummins ISX diesel engine can be run in a dual fuel configuration, meaning it can properly operate on diesel fuel and natural gas. The burning of a natural gas alternative preserves diesel thermal efficiencies. The more efficient engine can produce less emissions in turn. The ISX can achieve this by altering ignition delay and injection timing.

  3. Valve timing - Wikipedia

    en.wikipedia.org/wiki/Valve_timing

    With traditional fixed valve timing, an engine will have a period of "valve overlap" at the end of the exhaust stroke, when both the intake and exhaust valves are open. The intake valve is opened before the exhaust gases have completely left the cylinder, and their considerable velocity assists in drawing in the fresh charge. Engine designers ...

  4. Cummins M-series engine - Wikipedia

    en.wikipedia.org/wiki/Cummins_M-series_engine

    The Cummins M-series engine is a straight-six diesel engine designed and produced by Cummins.It displaces 10.8 litres (659.1 cu in).Introduced as the M11 in 1994, it was built on the previous L10 engine (same 4.921 inches (125.0 mm) cylinder bore, but a longer 5.787 inches (147.0 mm) piston stroke compared to the L10's 5.354 inches (136.0 mm) stroke).

  5. Cummins B Series engine - Wikipedia

    en.wikipedia.org/wiki/Cummins_B_Series_engine

    The 5.9 L Cummins, also known as the "12-Valve" Cummins was the first member of the Cummins B-Series to be used in a light truck vehicle. The 6BT used Bosch fuel systems, injector, and VE rotary pump and P7100 inline injection pumps. Some early 6BTs were supplied with CAV rotary pumps instead, before the Bosch system became the sole standard.

  6. Cummins L-series engine - Wikipedia

    en.wikipedia.org/wiki/Cummins_L-series_engine

    The Cummins L-series engine is a straight-six diesel engine designed and produced by Cummins. It displaces 8.9 litres (543.1 cu in), and began production in 1982 as the L10 at the Jamestown Engine Plant in Jamestown, New York. After lengthening its stroke from 136 to 147 mm, its displacement was enlarged to 10.8 litres and the engine renamed ...

  7. Schrader valve - Wikipedia

    en.wikipedia.org/wiki/Schrader_valve

    The Schrader valve consists of a valve stem into which a valve core is threaded. The valve core is a poppet valve assisted by a spring. A small rubber seal located on the core keeps the fluid from escaping through the threads. Using the appropriate tools, a faulty valve core can be immediately extracted from the valve stem and replaced with a ...

  8. Cummins C Series engine - Wikipedia

    en.wikipedia.org/wiki/Cummins_C_Series_engine

    The Cummins ISC also has a sister engine which is designed off the existing ISC 8.3-litre cylinder block which runs on compressed natural gas (CNG). Cummins reintroduced this engine as the C PLUS engine which has a maximum power rating of 280 horsepower (209 kW; 284 PS). A few thousand units of this engine are now roaming in the world operating ...

  9. Isolation valve - Wikipedia

    en.wikipedia.org/wiki/Isolation_valve

    An isolation valve is a valve in a fluid handling system that stops the flow of process media to a given location, usually for maintenance or safety purposes. [1] They can also be used to provide flow logic (selecting one flow path versus another), and to connect external equipment to a system. [ 2 ]
