ENGINE UNIT DETAILS INTAKE AND EXHAUST VALVE AND VALVE LIFTER

  1. CONSTRUCTION

    1. Narrower valve stems are used to reduce the intake and exhaust resistance and to reduce weight.

    2. The same valve springs are used for both the intake and exhaust valves. They are variable pitch springs that offer good valve following performance.

    3. Valve lifters with shimless valve adjustment is used for weight reduction.

    4. Diamond Like Carbon (DLC) coating is applied to improve fuel efficiency, which is achieved due to reduced friction.

      Tip:

      The adjustment of the valve clearance is accomplished by selecting and replacing the appropriate valve lifters. Adjusting valve lifters are available in 29 increments of 0.02 mm (0.000787 in.), from 5.12 mm (0.201 in.) to 5.68 mm (0.223 in.).
