Combustion Engine is used in our day to day life.
It affects our environment at a great extent also. In this ppt we have described the Effect of engines on Environment.
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.
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
