  • In The Process Of Producing Engine Valves, The Val

    In the process of producing engine valves, the valves are subjected to a first grind. Valves whose thicknesses are within the specification are ready for installation. Those valves whose thicknesses are above the specification are reground, while those whose thicknesses are below the specification are scrapped. Assume that after the first grind, 70% of the valves meet the specification, 20%

    This feature, also referred to as a negative radius of curvature (NROC), is designed to optimize valve opening and closing for greater engine power and reduced emissions. However, it introduces additional changing contact areas, making an already difficult grinding process even more hairy. In addition, new roller camshafts experience higher contact stresses than previous designs, which means

    An engine where the piston and valve can overlap is known as an interference design most modern engines are of an interference design. A non-interference engine has a clearance between the piston and valve, even when the valve is fully open and the piston is at the top of its stroke. Once a valve is bent it will fail to seat properly resulting in poor compression. Depending on the force of
