Why is the inlet valve bigger than the exhaust valve?
some of the gases are burnt and reduced befor going to the exhaust
Why inlet valve is bigger than exhaust valve?
because the inlet valve has to hold back pressure from the gas pump where as the exhaust valve has nothing to hold back but the compression of the ignited fuel and such a force is applied at the face of the valve. the face of the valve is in the cylinder so the force is a push not a pull meaning a bigger exhaust valve is not needed because the valve dose not have to fight back to keep it's self closed.
Why is the exhaust valve seat is made wider than the inlet valve seat?

You have a pair of sbc heads?
need to no if the first valve is intake or exhaust The intake valve is always bigger than the exhaust valve.
Which is bigger valve compare with inlet valve and exhaust valve?
Because much smaller than the exhaust air flow velocity, in order to reduce intake resistance and improve gas flow, to increase engine power! Some of the engine intake lift not only large, more than the intake valve (eg, five-valve, into the 3 row 2), valve diameter, but also large!
Exhaust valve smaller or bigger than intake valve in a turbo charged engine?
the exhaust valve will always be smaller as the piston is forcing the combusted gases out. The intake valves have to be bigger as the piston is only drawing the mixture in through sucktion.
Which valve is exhaust and which valve is intake on 94 GM 350ci?
look at the head with the valve cover off find where the exhaust manifold goes in tha is the exhaust valve or looking at the valves the first one is exhaust then intake then intake ,exhaust,exhaust,intake,intake,exhaust if you have the head off i think the intake valves are bigger than the exhaust
How can the inlet and exhaust valve be identified on an assembled engine?
On a fully assembled engine, the intake and exhaust valves will not be visible. If the cylinder head is removed from the engine, the valves will then be visible. The intake valve faces are usually larger than those of the exhaust valves, and can be easily distinguished visually.
Why the clearance of gap exhaust valve is big than intake valve?
The exhaust valve gets hotter than the intake valve.
