FUNDAMENTALS OF INTERNAL COMBUSTION ENGINES
INTERNAL COMBUSTION ENGINES
HISTORY OF ICE
• JJ LENOIR (1860) PIONEER OF IC ENGINE
• NICOLOUS OTTO & EUGEN LANGEN(1876) SI ENGINES
• RUDOLF DIESEL(1897) CI ENGINES
INTERNAL COMBUSTION ENGINES
ENGINE CLASSIFICATION
INTERNAL COMBUSTION ENGINES
Wankel engines• 3 LOBE ROTOR WHICH IS
DRIVEN ECCENTRICALLY IN A CASING & 3 VOLUMES ARE TRAPPED BETWEEN THE ROTOR AND THE CASING. THESE VOLUMES PERFORM INDUCTION, COMPRESSION, POWER & EXHAUST STROKES SEPERATELY.
• SEAL WEAR & HEAT TRANSFER ARE PROBLEM AREAS
ROTARY
INTERNAL COMBUSTION ENGINES
BASIC FUNCTION RECIPROCATING ENGINES
INTERNAL COMBUSTION ENGINES
Advantages• MECHANICAL SIMPLICITY• IMPROVED THERMAL
EFFICIENCY• DON’T NEED AUXILLARY
EQUIPMENT• SHORT START AND STOP
TIME• LOW INITIAL COST• EFFICENT PERFORMANCE
Disadvantages• FUEL COST
• WORKING FLUID ONLY LIQUID OR GASEOUS AT GIVEN SPECIFICATIONS
• VIBRATION PROBLEMS
