  2. Crankcase ventilation system - Wikipedia

    en.wikipedia.org/wiki/Crankcase_ventilation_system

    The first refinement in crankcase ventilation was the road draught tube. This is a pipe running from the crankcase (or the valve cover on an overhead valve engine) down to a downwards-facing open end located in the vehicle's slipstream. When the vehicle is moving, airflow across the open end of the tube creates suction (a "draught" or draft ...

  3. 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 ...

  4. Onboard refueling vapor recovery - Wikipedia

    en.wikipedia.org/wiki/Onboard_refueling_vapor...

    The vent/rollover valve provides a method of controlled escape for gasoline vapors during the refueling process. It has a mechanism which closes the vent in the event the vehicle rolls over, to prevent spilling of VOCs or fuel in general. It also acts as a fill limiter. [8] [dead link ‍]

  5. Crankcase heater - Wikipedia

    en.wikipedia.org/wiki/Crankcase_heater

    The crankcase heater keeps refrigerant at a temperature higher than the coldest part of the system. A crankcase heater generally has the same electrical symbol as a resistor because it converts electricity directly into heat via electrical resistance. The resistance in the heater coil determines the heat it produces when voltage is applied. [1]

  6. 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 ...

  7. Blowoff valve - Wikipedia

    en.wikipedia.org/wiki/Blowoff_valve

    A vacuum hose connected to the intake manifold downstream of the throttle provides a reference pressure for the blowoff valve.. When the throttle is open, the air pressure on both sides of the blowoff valve's piston is equal, therefore the spring holds the valve closed.

  8. Chevrolet Turbo-Air 6 engine - Wikipedia

    en.wikipedia.org/wiki/Chevrolet_Turbo-Air_6_engine

    [5]: 44 The use of separate exhaust ports rather than twinned or siamesed ports helps avoid problems with distortion caused by a concentration of heat at these locations. [17] There is a single cast-iron camshaft located in the crankcase. The shaft has only nine cam lobes on it — the symmetrical arrangement of valves allows three double-width ...

  9. List of auto parts - Wikipedia

    en.wikipedia.org/wiki/List_of_auto_parts

    This is a list of auto parts, which are manufactured components of automobiles.This list reflects both fossil-fueled cars (using internal combustion engines) and electric vehicles; the list is not exhaustive.
