INTERNAL COMBUSTION ENGINE

BIOGRAPHY

• born March 18, 1858 in France, died september 29 1913
• thought to be lost at sea, no one knows what happened
• some think he fell over board and drowned
• German thermal engineer who invented the internal combustion engine

DIESEL ENGINE

HOW DOES IT WORK

• takes in air through the intake valve during the first stroke
• during the 2nd stroke the intake valves close and compressthe air
• the air heats up to 1300 degrees
• in the 3rd stroke diesel fuel is injected right into the cylinder
• the fuel ignites due to the high tempeture.

CONTINUED

• the explosion forces the piston which sends power to the crank shaft
• the 4th stroke is the process is when the spent-fuel exits through the valves
• then the cycle is repeated.

USES

• trains, ships, trucks, power plants even submarines use diesel engines
• 40% more efficient then other engines
• compressing the fuel makes it so it burns more completely
• use less deisel then you would with gasoline
• its a natural lubricant meaning it would run with less friction.
