Camshaft Articles | D. Elgin Cams - Santa Rosa, CA

Exhaust valves and ports are always made smaller that the intakes, because exhaust flow gets pushed first by high cylinder pressure, then by the piston on the way up. In 2-valve engines the exhaust port flows between 60% and 80% of the intake. Exhaust flow in 4-valve engines is very high, somewhere in the 80% to 90% region.

Valve Timing Events and the Order of Importance - Engine ...

Apr 15, 2016 · Exhaust valve closing (EVC) 4. 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.

Tech Article - Cam timing explained - Schnitz Racing

The opening and closing process of an inlet or exhaust valve as controlled by a cam lobe constitutes a complete "event" in the cycle of the engine. Like any event, it has a beginning and an end. Naturally, then it also has a middle or center. The location of this center in relation to the rotational position of the crankshaft is known as ...

The exhaust lobe is fixed relative to the intake lobe by the lobe separation angle. All of the events can be shifted by advancing or retarding the cam during installation. Rather than the four timing events above, we prefer to use the following equivalent set of parameters: Cam advance; Intake valve duration; Exhaust valve duration

How Camshafts Work | HowStuffWorks

The animation below shows how a regular cam and a performance cam have different valve timing. Notice that the exhaust (red circle) and intake (blue circle) cycles overlap a lot more on the performance cam. Because of this, cars with this type of cam tend to run very roughly at idle.

The valve spindle is fitted with a winged valve rotator. The kinetic energy in the exhaust gas rotates the valve a small amount as it passes. This keeps the valve at an even temperature and helps reduce the build up of deposits on the valve seat. The cage of the exhaust valve is of cast iron as is the guide.
