In a piston engine, the valve timing is the precise timing of the opening and closing of the valves. In an internal combustion engine those are usually poppet valves and in a steam engine they are usually slide valves or piston valves.
Valve overlap
With traditional fixed valve timing, an engine will have a period of "valve overlap" at the end of the exhaust stroke, when both the intake and exhaust valves are open. The intake valve is opened before the exhaust gases have completely left the cylinder, and their considerable velocity assists in drawing in the fresh charge. Engine designers aim to close the exhaust valve just as the fresh charge from the intake valve reaches it, to prevent either loss of fresh charge or unscavenged exhaust gas. In the diagram, the valve overlap periods are indicated by the overlap of the red and blue arcs. Key:

Inlet Valve is bigger because it helps in increasing Volumetric efficiency

Nice comment.
Sir Intlet valve is bigger than exhaust valve,because to allow the sufficient amount of airfuel mixture to get in the cylinder.

Sir outlet valve is also bigger than inlet valve
Brother kn SA cycle kha uses hota ha in engine. jasay k jenbacher engine ma miller cycle uses hota ha or inlet value compression ma b open ho Jata ha(due to high performance) assay hi baqi cycle ma bi bata dana plz tell me Awaiting your response
Yes sir, inlet valve बडा होता है exhaust valve से because jyada se jyada charge अंदर आये ओर exhaust मे से जाणे वाली बर्न गॅसेस के साथ cylinder मे आया हुआ चार्ज निकल ना जाय |

Intake valve Diameter is big than outlet valve.
Exhaust pressure high hone SE or atmospheric pressure high hone SE exhaust air aaram se atmosphere me chali jati he to exhaust valve chhota Hota he, usme koe dikkat Nahi aayegi And inlet valve bada because vacuum created during suction so easily air fuel run is it right both?

Sir inlet valve is greater than outlet valve
Acha, valve timing overlap matlab dono valve ka ek he samay me open rehna. Aur aaj yeh v jana ki inlet valve zyada bara hota h qui ki zyada air suck kr ske

Sir Automatic gear ke bare me batao kaise kaam karta hai sahi se samajh me nhi aata hai usme 1 number kaunsa hai baaki number kaunsa paart kaam karta hai
An inlet valve is always bigger than an exhaust valve because air is sucked in unless turbo where it is blown in.

Sir last question agar inlet valve 20 degree before tdc mai open ho raha hai or idar exhaust 10 degree after tdc ho raha hai to is hisab se exhaust 10 degree before tdc mai hona chahiye na qki suction toh 10 degree pehle ho raha hai lekin baad mai suction after 10 degree tdc ho raha hai???

Typically, the exhaust valves are larger than the intake valves. This is because the exhaust gases are much hotter and under higher pressure than the incoming air and fuel mixture.
