    Feeler gauge set (25 pieces, 0.03~1.0 mm measurement range) Measuring the valve clearance of a DOHC engine, between camshaft and tappet (here: 0.004 in ≈ 0.10 mm). A feeler gauge is a tool used to measure gap widths. Feeler gauges are mostly used in engineering to measure the clearance between two parts. [1]

  4. Valve timing - Wikipedia

    en.wikipedia.org/wiki/Valve_timing

    The valve timing of a diesel engine also depends on tappet clearance of the inlet and exhaust valves. If tappet clearance is less, then valve will open early and close late. [2] If tappet clearance is more, then valve will open late and close early. Tappet clearance is measured by an instrument called feeler gauge.

  5. Hydraulic tappet - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_tappet

    A hydraulic tappet, also known as a hydraulic valve lifter or hydraulic lash adjuster, is a device for maintaining zero valve clearance in an internal combustion engine. Conventional solid valve lifters require regular adjusting to maintain a small clearance between the valve and its rocker or cam follower .

  8. Desmodromic valve - Wikipedia

    en.wikipedia.org/wiki/Desmodromic_valve

    A desmodromic valve is a reciprocating engine poppet valve that is positively closed by a cam and leverage system, rather than by a more conventional spring. The valves in a typical four-stroke engine allow the air/fuel mixture into the cylinder at the beginning of the cycle and exhaust spent gases at the end of the cycle. In a conventional ...
