In IC engine, the inlet valve is always larger in diameter as compared to exhaust by 20-35 % in dia. to improve the volumetric efficiency and to achieve good power and performance even at high speed by overcoming the blow losses.
An IC engine comes in all sizes and shapes so the weights and dimensions of the valve system will differ. Most are a two-stroke or two-cycle engine.
The intake valve is usually larger.
Inlet valve is open when piston moves from top dead center to bottom dead center inlet valve open and provide proper amount of fuel and air to the cylinder.
explain the working of ic engine cooloing systems
Automobile engines are ic (internal combustion).
The AC recharge valve for a 2003 Ford Focus with a Zetec engine is near the firewall. It is the larger of the two lines going to the compressor.
The AC low pressure valve on a 1996 Isuzu Rodeo is located in the back of the engine compartment. The valve is on the larger of the two hoses that run from the evaporator to the compressor.
for mechanical and dynamic requirements. By studing correct timing of opening and closing of inlet and exhaust valves improves power and efficiency of engine and reducing of fuel consumption be done.

Very carefully
Jiggle valve is a small aperture valve in outer casing of engine (IC engines) thermostat which vents the air trapped inside the cooling system when filling or topping up the system with coolant and hence ensures the 'full coolant no air trap' condition in radiator and water jackets.
This is the ratio between the total volume to the clearance volume in IC engines
