2 stroke diesel engine
A two-stroke (or two-cycle) engineis a type of internal combustion enginewhich completes a power cycle with two strokes (up and down movements) of the piston during only one crankshaft revolution. This is in contrast to a "four-stroke engine", which requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time.
Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the "power band". Compared to four-stroke engines, two-stroke engines have a greatly reduced number of moving parts, and so can be more compact and significantly lighter.
CONSTRUCTION DETAILS:
1. Cylinder: In it the piston makes a reciprocating process motion
combustion system, It fits into cylinder
2. Piston: It is a cylindrical component fitted into the cylinder forming the moving boundary of the
3. Combustion Chamber: The space enclosed in the upper part of the cylinder, by the head and the
piston top during the combustion process.
out of cylinder
4. Inlet Outlet ports: They are provided on the side of cylinder to regulate the charge coming in and
5.Fuel Injector: It injects the fuel in combustion chamber to initiate combustion process for power
stroke
6. Connecting Rod: It interconnects crank shaft and the piston
7. Fly Wheel:The net torque imparted to the crankshaft during one complete cycle of operation of the
ngine fluctuates causing change in angular velocity of shaft. In order to achieve uniform torque an
nternal mass is attached to the output shaft & this is called as fly wheel.
