  2. Crankcase ventilation system - Wikipedia

    en.wikipedia.org/wiki/Crankcase_ventilation_system

    PCV valve on Ford Taunus V4 engine (feeding from left side valve cover into the inlet manifold) 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).

  3. Exhaust manifold - Wikipedia

    en.wikipedia.org/wiki/Exhaust_manifold

    When the exhaust valve opens, the high pressure exhaust gas escapes into the exhaust manifold or header, creating an "exhaust pulse" comprising three main parts: The high-pressure head is created by the large pressure difference between the exhaust in the combustion chamber and the atmospheric pressure outside of the exhaust system

  4. Ceramic engine - Wikipedia

    en.wikipedia.org/wiki/Ceramic_engine

    A ceramic engine is an internal combustion engine made from specially engineered ceramic materials. Ceramic engines allow for the compression and expansion of gases at extremely high temperatures without loss of heat or engine damage. [1] Proof-of-concept ceramic engines were popularized by successful studies in the early 1980s and 1990s.

  5. Schrader valve - Wikipedia

    en.wikipedia.org/wiki/Schrader_valve

    The Schrader valve consists of a valve stem into which a valve core is threaded. The valve core is a poppet valve assisted by a spring. A small rubber seal located on the core keeps the fluid from escaping through the threads. Using the appropriate tools, a faulty valve core can be immediately extracted from the valve stem and replaced with a ...

    en.wikipedia.org/wiki/Chevrolet_small-block...

    1987 – The valve cover surfaces were changed so that the mounting lip was raised and the bolt location was moved from 4 bolts on the perimeter to 4 bolts along the centerline of the valve covers (this design debuted on the Corvette in 1986, and the Chevrolet 4.3L 90 degree V6 the year before). Also changed were the mounting angles of the two ...

  7. Valve guide - Wikipedia

    en.wikipedia.org/wiki/Valve_guide

    Valve guides are typically shaped in a tube with a flare at one end. Their replacement involves removing the worn part by driving it out with a hammer and specifically-shaped punch. Installation may involve shrink-fitting , heating the cylinder head and cooling the valve guide so as to ease insertion, then driving the new guide in quickly with ...

  8. Flathead engine - Wikipedia

    en.wikipedia.org/wiki/Flathead_engine

    A crossflow T-head sidevalve engine The usual L-head arrangement Pop-up pistons may be used to increase compression ratio Flathead with Ricardo's turbulent head. A flathead engine, also known as a sidevalve engine [1] [2] or valve-in-block engine, is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve ...

  9. System basis chip - Wikipedia

    en.wikipedia.org/wiki/System_Basis_Chip

    A system basis chip (SBC) is an integrated circuit that includes various functions of automotive electronic control units (ECU) on a single die. [ 1 ] [ 2 ] It typically includes a mixture between digital standard functionality like communication bus interfaces and analog or power functionality, denoted as smart power.
