  2. Cylinder head porting - Wikipedia

    en.wikipedia.org/wiki/Cylinder_head_porting

    Up until that point all that can happen is the higher pressure gas filling the volume of the runner decompresses or expands into the low-pressure region advancing up the runner. (Once the low-pressure wave reaches the open end of the runner it reverses sign, the onrushing air forces a high pressure wave down the runner.

  3. Crankcase ventilation system - Wikipedia

    en.wikipedia.org/wiki/Crankcase_ventilation_system

    The intake manifold vacuum, with wide open throttle, is lower in these conditions, which causes the PCV valve to open and the crankcase gases flow to the intake system. [13] The greater flow rate of intake air during these conditions means that a greater quantity of blow-by gases can be added to the intake system without compromising the ...

    en.wikipedia.org/wiki/Chevrolet_Corvette_C7.R

    The Chevrolet Corvette C7.R is a grand tourer racing car built by Pratt Miller and Chevrolet for competition in endurance racing between 2014 and 2019. It is a replacement for the Corvette C6.R racing car, using the C7 generation Chevrolet Corvette as a base.

  5. Crossflow cylinder head - Wikipedia

    en.wikipedia.org/wiki/Crossflow_cylinder_head

    A crossflow head gives better performance than a Reverse-flow cylinder head (though not as good as a uniflow), but the popular explanation put forward for this — that the gases do not have to change direction and hence are moved into and out of the cylinder more efficiently — is a simplification since there is no continuous flow because of valve opening and closing.

  6. 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 intervening carburetor or throttle body leading to the intake manifold. It is a ...

    The Corvette Stingray Coupe went on sale in the US in the third quarter of 2013, as a 2014 model-year vehicle. The 2014 Corvette was equipped with a Tremec TR-6070 7-speed manual with rev-matching for both downshifts and upshifts, or a Hydramatic 6L80 6-speed paddle-shift automatic transmission optimized for Active Fuel Management.

  9. Manifold (fluid mechanics) - Wikipedia

    en.wikipedia.org/wiki/Manifold_(fluid_mechanics)

    Types of manifolds in engineering include: Exhaust manifold An engine part that collects the exhaust gases from multiple cylinders into one pipe. Also known as headers. Hydraulic manifold A component used to regulate fluid flow in a hydraulic system, thus controlling the transfer of power between actuators and pumps Inlet manifold (or "intake ...
