Working Of Petrol Engine INTRODUCTION • Petrol Engine, type of internal-combustion engine in which heat caused by air compression ignites the fuel. • Invented by scientist Rudolf Diesel . • • 1. 2. 3. 4.
PRINCIPLE The Internal-combustion Engine Generated Mechanical Energy by Burning Fuel in A Combustion Chamber. WORKING It Takes Place In Four Strokes :Intake Compression Power Exhaust
INTAKE • Air Enters In The Cylinder.
COMPRESSION • Pistor comprence the air to 1/16 of the interior volume. Air acquires the temperature to 1000 c.
POWER Fuel Combustion Occurs Due To High Temperature And Produces Gases Like Co2 , Co etc. Pressure Of Gases Forces The Piston.
EXHAUST • Piston Acquires Its First Position and Air Enters. Value Opens Gases Pass Out. BIBLIOGRAPHY Textbook of Science (9th Class) Students of G.H.S. Tehna, Faridkot (Punjab) Sukhpreet Kaur Rajit Manohar Singh
