Valve Timing Setting

Valve Timing Setting. This relation between the valve opening timings to the piston moves from the top dead centre (tdc) to the bottom dead centre (bdc) can be represented on a circle. Engine valve timing is the most critical process of ic engines.

The most accurate way of doing this is to use a modified spark plug, with a fixed probe in place of the electrode. These are commonly poppet valves in an internal combustion engine, and slide valves or piston valves in a steam engine. To optimise the breathing, engine requires different valve timing at different speed.

What is Valve Timing How It Affects Engine PerformanceSource: carbiketech.com

As you know, valves activate the breathing of engine. Tramming, an old but accurate method of setting valve and ignition timing, can be a great way to set basic timing.

To prepare the cylinder head for valve timing, the valves, springs, rockers etc., must be installed, ready as for use and the valve clearances set to the checking clearances (.025” on a k17/8cam and.030” on a k17/11 cam). Advancing the cam improves low end torque and response at the expense of high rpms.

True full lift is at the centre of this dwell period. Roughly position the cam at true lift position.

How to set 16 valve timing without timing marks. (Fire 1Source: www.youtube.com

The book states that both the fwd and rev eccentrics need to be set (90+) 7.5 degs in advance of the crank position, i’m not planning to go into depth of why this is, as this is discussed in detail on the web, however the principle reason is that the advanced valve timing is required to stop steam flow to the cylinder a. Exhaust timing follows a similar calculation.

But first of all, the protractor needs to be zeroed at t.d.c. Advancing the cam improves low end torque and response at the expense of high rpms.

The timing of the opening closing of valves is specified in degrees corresponding to the position of engine’s pistons. A valve timing diagram is a graphical representation of the opening and closing of the intake and exhaust valve of the engine, the opening and closing of the valves of the engine depend upon the movement of piston from tdc to bdc, this relation between piston and valves is controlled by setting a graphical representation between these two, which is known as valve timing diagram.

This relation between the valve opening timings to the piston moves from the top dead centre (tdc) to the bottom dead centre (bdc) can be represented on a circle. It can be varied by modifying the camshaft, or it can be varied during engine operation by variable valve timing.
