Effect of Combustion Engines on Environment
- 1. COMBUSTION ENGINE ENVIRONMENTAL STUDIES Presented By : Jay Padhariya (19K050 Shivam Padmani (19K0
- 2. CONTENTS • INTRODUCTION • BACKTRACING OF STEAM ENGINES • RESOURCES USED BY STEAM ENGINES • HOW ENGINES WORKS? • IT’S HARMFUL EFFECTS TOWARDS ENVIRONMENT
- 3. INTRODUCTION WE USE ENGINES IN OUR DAILY LIFE EXTENSIVELY. IT CONVERT ONE FORM OF ENERGY TO OTHER FORM. THEY BURN A ⛽FUEL⛽ TO PRODUCE HEAT WHICH IS USED TO DO WORK.
- 4. BACKTRACING OF ENGINE Engin e Engine Iron Blast Furnace Iron Ore
- 5. RESOURCES USED BY COMBUSTION ENGINE • FUEL LIKE COAL , PETROL , DIESEL , NATURAL GAS , ETC. ARE CONSUMED. • MANY METAL ALLOYS.
- 6. HOW DO INTERNAL COMBUSTION ENGINES WORK ? IT IS A COMBUSTION ENGINE THAT PERFORMS MECHANICAL WORK BY BURNING FUEL. RAISING THE TEMPERATURE OF A GAS INCREASES THE PRESSURE THAT MAKES THE GAS WANT TO EXPAND. IT CONSISTS OF : 1. A PISTON 2. SPARK PLUG 3. CRANKSHAFT
- 7. ITS HARMFUL EFFECTS TOWARDS ENVIRONMENT • AIR POLLUTION • IT EMITS GASES LIKE SULFER DIOXIDE, NITROGEN OXIDES • THIS LEADS TO SMOG , ACID RAINS , TOXINS IN THE ENVIRONMENT. • CO2 – CAUSES GREENHOUSE EFFECT • SO2 – ACID RAIN
- 8. ITS HARMFUL EFFECTS TOWARDS ENVIRONMENT • THEY ARE ON AVERAGE 20% THERMALLY EFFICIENT. • CREATES VERY HIGH TEMPERATURE USUALLY AROUND 1500 DEGREE CELCIUS. • POLLUTE AIR IN SURROUNDING • SOMETIMES CREATE NOISE WHICH CAUSES NOISE POLLUTION.
- 9. ALTERNATIVE TO COMBUSTION ENGINES • USE SOLAR POWERED ENGINES • ELECTRIC AUTOMOBILES SHOULD BE PROMOTED. • USE ELECTRIC ENGINE, HYDROGEN ENGINE, COMPRESSED AIR ENGINE, STEAM ENGINE ETC. SOLAR CAR
