Automobile Lab Manual
AUTOMOBILE ENGG LAB
Batch :- 3rd Year, B.E.
To The
Department of Mechanical Engineering
ENGINEERING COLLEGE, BIKANER 26 August 2010
Syllabus
1. Valve refacing and valve seat grinding and checking for leakage of valves
2. Trouble sooting in cooling system of an automotive vehicle.
3. Trouble sooting in the ignition system , setting of contact breaker ponts and spark plug gap.
4. Demonstration of steering system and measurement of steering geometry angle and their impact on vehicle performance.
5. Trouble sooting in braking with specific reference to master cylinder, brake shoe, overhauling of system and adjusting of the system and its testing.
6. Fault diagnosis in trans mission system including clutches, gear box assembly and differential.
7. Replacing of ring and studying the method of replacing after repair
Experiment no:- 1
Object:- To study the engine valve and there maintenance.
Requirement:- sets of valve, there setting and accessories.
Poppet valve:- it’s main part are head and stem. The lower portion of the head which is called valve face is ground to an angle of 300 or 450. Thereby matching the valves face in the head or block the leakage of gas.
Valve actuating mechanism:-
(1) Side valve mechanism:- in this system the tappet is interpost between the cam and valve stem. The tappet slides vertically in it’s guide, which further actuates the valve against the spring tension.
(2) Overhead valve mechanism:- in this system valve is mounted at overhead the engine and also in opposite direction that if in case of valve side
