What is timing procedure for exhaust valve opening?
Exhaust valve opening (EVO) Overhead cam timing can be tricky on some engines. Always refer to the OEM timing procedure so you know how the timing marks are supposed to be aligned. On some engines, you have to count the chain links between sprockets to get the proper alignment.
How to calculate the duration of intake valve timing event?
To calculate the duration of any intake valve timing event, add 180° to the intake opening and closing time. For example, if an intake valve opens at 12° before top dead center (BTDC) and closes at 40° after bottom dead center (ABDC), the duration of the valve timing event is 232°. Exhaust timing follows a similar calculation.
Is there a way to adjust engine valves without a manual?
There is a way without having a manual to adjust the engine valves on any inline diesel engine because of the universal design that makes it easy to carry out this procedure. This procedure is called the rocker method that uses the intake and exhaust valve position as a reference while turning over the engine by hand.
What are the basic requirements for a control valve?
The basic requirements and selection depend on their ability to perform specific functions such as: 1. Ability to throttle or control the rate of flow; 2. Lack of turbulence or resistance to flow when fully open – turbulence reduces head pressure; 3.

What happens when intake valve is opened too early?
The amount of overlap, or the area between the intake opening and the exhaust closing, and where it occurs, is one of the most critical points in the engine cycle. If the intake valve opens too early, it will push the new charge into the intake manifold.
