1.What is The Function Of Camshaft?
2. what is spark plug ?
Cars typically have four-stroke gasoline engines, which means there are four strokes, or movements, to the moving parts inside the engine per rotation. Inside each cylinder is a piston, which moves up and down within the cylinder to compress the gas for combustion, and pushes the exhaust gases out after combustion.
The piston is operated by an arm that attaches to the crankshaft, a shaft that extends through the bottom of the engine. The piston goes up and down twice during each rotation, hence the four strokes -- up, down, up, down.
The spark plug is positioned at the top of the cylinder, where the air-fuel ratio is compressed. The tip of the plug sits inside the engine, recessed into the side of the cylinder wall. The other end remains outside the engine and is attached to a wire that is also attached to the distributor.
3. What is The Function Of The Carburetor?
4.What Is The Function Of PISTON?
5.what are the Advantages of Lubrication of I.C Engines ?
a. It reduces wear and tear of the moving parts.
b. It damps down the vibrations of the engine.
c. It dissipates the heat generated from the moving parts due to friction.
d. It cleans the moving parts.
e. It makes the piston gas-tight.
6.What is Wankel engine ?
7.What is Gear box and its application ?
There are many application,Its used in automobile (i.e.Progreesive type,synchromesh, constant mesh, selective type,automatically).Gear box is also used in Rolling mill(i.e. pinion gear box, reduction gear box, speed increaser,reduction cum pinion.)
8.What Is Otto Cycle?
The processes are described byProcess 1-2 is an isentropic compression of the air as the piston moves from bottom dead centre (BDC) to top dead centre (TDC).
Process 2-3 is a constant-volume heat transfer to the air from an external source while the piston is at top dead centre. This process is intended to represent the ignition of the fuel-air mixture and the subsequent rapid burning.
Process 3-4 is an isentropic expansion (power stroke).
Process 4-1 completes the cycle by a constant-volume process in which heat is rejected from the air while the piston is a bottom dead centre.
9.What is Scavenging Of I.C Engines?
Ans: The scavenging, in an I.C Engine, is the process of removing the burnt gases from the combustion chamber of the engine cylinder. Through there are many types of scavenging are there yet following are important:
a. Crossflow Scavenging.
b.Back flow or loop Scavenging.
c.Uniflow Scavenging.
10. What is Governing Of I.C Engines?
Ans: The process of providing any arrangement, which will keep the engine speed constant (according to the changing load conditions) is know as Governing of I.C Engines. There are many types of methods for Governing of I.C Engines, yet few are important types:
a. Hit and miss Governing.
b. Qualitative Governing.
c. Quantitative Governing.
d. Combination system of Governing.
