  2. Exhaust brake - Wikipedia

    en.wikipedia.org/wiki/Exhaust_brake

    An exhaust brake is a means of slowing a diesel engine by closing off the exhaust path from the engine, causing the exhaust gases to be compressed in the exhaust manifold, and in the cylinder. Since the exhaust is being compressed, and there is no fuel being applied, the engine slows down the vehicle: the crankshaft (and, hence, the wheels ...

  3. Exhaust gas recirculation - Wikipedia

    en.wikipedia.org/wiki/Exhaust_gas_recirculation

    Adding exhaust gas therefore reduces pressure and temperature during the isentropic compression in the cylinder, thereby lowering the adiabatic flame temperature. In a typical automotive spark-ignited (SI) engine, 5% to 15% of the exhaust gas is routed back to the intake as EGR. The maximum quantity is limited by the need of the mixture to ...

  4. Back pressure - Wikipedia

    en.wikipedia.org/wiki/Back_pressure

    Two similar pipings with same pressure distance and head. The second pipe contains some obstructions for flow resulting in less discharge. A common example of backpressure is that caused by the exhaust system (consisting of the exhaust manifold, catalytic converter, muffler and connecting pipes) of an automotive four-stroke engine, which has a negative effect on engine efficiency, resulting in ...

    XLT (2001–2007): As the top-of-the-line trim level of the Escape for 2001, and the most popular trim level of the Escape throughout its entire run (2001–2007), the XLT added the following equipment to the base XLS trim level: 16-inch alloy wheels, security alarm, cloth seating surfaces, and an enhanced interior. Options included an AM/FM ...

    en.wikipedia.org/wiki/Exhaust_system

    Exhaust system of the Opel Corsa B 1.2 petrol Exhaust manifold (chrome plated) on a car engine. An exhaust system is used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes. Depending on the overall system ...

  7. Engine braking - Wikipedia

    en.wikipedia.org/wiki/Engine_braking

    Exhaust gas recirculator (EGR) valve redirects exhaust gas back into the engine intake, often through a restricted/narrow pipe. Diesel particulate filter (DPF) is designed to capture soot particles that would otherwise be released into the atmosphere; it greatly obstructs exhaust flow and can sap almost as much power as a small air conditioning ...
