  3. Generac - Wikipedia

    en.wikipedia.org/wiki/Generac

    In 1998, Generac sold its portable products division to the Beacon group, a private equity firm, who later sold it to Briggs & Stratton Corporation. Upon expiration of a non-compete agreement related to the sale in 2007, Generac re-entered the portable generator market in 2008. [7] In late 2006, Generac was purchased by CCMP Capital of New York ...

  4. Fuel pump - Wikipedia

    en.wikipedia.org/wiki/Fuel_pump

    On engines that use a carburetor (e.g. in older cars, lawnmowers and power tools), a mechanical fuel pump is typically used in order to transfer fuel from the fuel tank into the carburetor. These fuel pumps operate at a relatively low fuel pressure of 10–15 psi (0.7–1.0 bar).

    low-pressure fuel tank mounted fuel lift pump with underfloor electric fuel relay pump, timing belt-driven high-pressure injection pump delivering up to 1,850 bar (26,830 psi) pressure for the common rail (CR) fuel rail, direct injection (DI) with eight-nozzle output piezo fuel injectors; Bosch EDC 17 electronic engine control unit (ECU)

  6. Thrust-specific fuel consumption - Wikipedia

    en.wikipedia.org/wiki/Thrust-specific_fuel...

    Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence thrust-specific .

  7. Duramax V8 engine - Wikipedia

    en.wikipedia.org/wiki/Duramax_V8_engine

    The engine gained new 29,000 PSI piezo injectors as well as a completely reworked fuel system which was now powered by the Bosch CP4 pump, that also now supports up to 20% biodiesel mixtures and a urea injection (to reduce nitrogen oxides) with a 5.3 gallon DEF tank. This engine has a fuel injector in the exhaust tract, to allow raw fuel ...

  8. Reid vapor pressure - Wikipedia

    en.wikipedia.org/wiki/Reid_vapor_pressure

    Reid vapor pressure (RVP) is a common measure of the volatility of gasoline and other petroleum products. [1] It is defined as the absolute vapor pressure exerted by the vapor of the liquid and any dissolved gases/moisture at 37.8 °C (100 °F) as determined by the test method ASTM-D-323, which was first developed in 1930 [2] and has been revised several times (the latest version is ASTM D323 ...

    These specifications are published by the Gas Processors Association (GPA) [10] and the American Society of Testing and Materials. [11] Propane/butane blends are also listed in these specifications. Propylene , butylenes and various other hydrocarbons are usually also present in small concentrations such as C 2 H 6 , CH 4 , and C 3 H 8 .
