  2. Crankcase ventilation system - Wikipedia

    en.wikipedia.org/wiki/Crankcase_ventilation_system

    A crankcase ventilation system (CVS) removes unwanted gases from the crankcase of an internal combustion engine. The system usually consists of a tube, a one-way valve and a vacuum source (such as the inlet manifold). The unwanted gases, called "blow-by", are gases from the combustion chamber which have leaked past the piston rings. Early ...

  3. Oil catch tank - Wikipedia

    en.wikipedia.org/wiki/Oil_Catch_Tank

    An oil catch can is fitted in line of the crank case breather system. It is placed in between the breather outlet and the intake system. As the crank vapors pass through the catch can the oil droplets, un-burnt fuel, and water vapor condense and settle in the tank. This stops them from reaching the intake and causing the issues mentioned above.

  4. Crankcase - Wikipedia

    en.wikipedia.org/wiki/Crankcase

    A crankcase is the housing in a piston engine that surrounds the crankshaft. In most modern engines, the crankcase is integrated into the engine block. Two-stroke engines typically use a crankcase-compression design, resulting in the fuel/air mixture passing through the crankcase before entering the cylinder(s). This design of the engine does ...

  5. Vehicle emissions control - Wikipedia

    en.wikipedia.org/wiki/Vehicle_emissions_control

    The first effort at controlling pollution from automobiles was the PCV (positive crankcase ventilation) system. This draws crankcase fumes heavy in unburned hydrocarbons – a precursor to photochemical smog – into the engine's intake tract so they are burned rather than released unburned from the crankcase into the atmosphere. Positive ...

  6. Inlet manifold - Wikipedia

    en.wikipedia.org/wiki/Inlet_manifold

    This is known as a positive crankcase ventilation system, in which the gases are burned with the fuel/air mixture. The intake manifold has historically been manufactured from aluminium or cast iron, but use of composite plastic materials is gaining popularity (e.g. most Chrysler 4-cylinders, Ford Zetec 2.0, Duratec 2.0 and 2.3, and GM's Ecotec ...

  7. Engine configuration - Wikipedia

    en.wikipedia.org/wiki/Engine_configuration

    Radial engines have cylinders mounted radially around a central crankcase. Rotary engines have a similar configuration, except that the crankshaft is fixed and the cylinders rotate around it. (This is different from the Wankel engine configuration described below.) Radial and rotary engine designs were widely used in early aircraft engines.

    The game would be played in Glendale, Ariz., if the location needs to be changed. "The NFL's priority is the safety of the Los Angeles community," the league said in a statement.

  9. Manifold vacuum - Wikipedia

    en.wikipedia.org/wiki/Manifold_vacuum

    Manifold vacuum, or engine vacuum in a petrol engine is the difference in air pressure between the engine's intake manifold and Earth's atmosphere.. Manifold vacuum is an effect of a piston's movement on the induction stroke and the airflow through a throttle in the intake manifold of an engine.
