  2. MAP sensor - Wikipedia

    en.wikipedia.org/wiki/MAP_sensor

    Thus, a MAP sensor will always read 100 kPa more than a boost sensor measuring the same conditions. A MAP sensor will never display a negative reading because it is measuring absolute pressure, where zero is the total absence of pressure. Vacuum is measured as a negative pressure relative to normal atmospheric pressure. Vacuum-Boost sensors can ...

  3. Exhaust gas temperature gauge - Wikipedia

    en.wikipedia.org/wiki/Exhaust_gas_temperature_gauge

    An exhaust gas temperature gauge (EGT gauge or EGT sensor) is a meter used to monitor the exhaust gas temperature of an internal combustion engine in conjunction with a thermocouple-type pyrometer. EGT gauges are found in certain cars and aeroplanes. By monitoring EGT, the driver or pilot can get an idea of the vehicle's air-fuel ratio (AFR).

  4. Diesel particulate filter - Wikipedia

    en.wikipedia.org/wiki/Diesel_particulate_filter

    Sensors upstream and downstream of the DPF (or a differential pressure sensor) provide readings that initiate a metered addition of fuel into the exhaust stream. There are two methods to inject fuel, either downstream injection directly into the exhaust stream, downstream of the turbo, or fuel injection into the engine cylinders on the exhaust ...

  5. Exhaust pulse pressure charging - Wikipedia

    en.wikipedia.org/wiki/Exhaust_pulse_pressure...

    Exhaust pulse pressure charging (EPPC) is a system for supercharging two-stroke diesel engines of the loop-scavenge type. Loop-scavenge engines cannot be pressure-charged in the same way as uniflow engines or four-stroke engines because the inlet and exhaust ports are open at the same time.

  6. Sterling Bullet - Wikipedia

    en.wikipedia.org/wiki/Sterling_Bullet

    The Sterling Bullet is a medium-duty vocational truck that was marketed by Sterling Trucks from 2007 to 2009. [1] It is a rebadged Dodge Ram, specifically the 3500/4500/5500 Chassis Cab variant, with the most visible difference being the unique grille compared to the Ram.

  7. 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 ...

  8. Propelling nozzle - Wikipedia

    en.wikipedia.org/wiki/Propelling_nozzle

    When the pressure ratio across a convergent nozzle exceeds a critical value, the flow chokes, and thus the pressure of the exhaust exiting the engine exceeds the pressure of the surrounding air and cannot decrease via the conventional Venturi effect. This reduces the thrust producing efficiency of the nozzle by causing much of the expansion to ...

  9. Exhaust system - Wikipedia

    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 ...
