A two-stroke engine is which it completes its cycle of operation in one complete revolution of the crankshaft in other word in two stroke of the piston.
Two-stroke engine are basically two types and its depend on the scavenging method.
Types of two-stroke engine are listed below :
Two-stroke engine are basically two types and its depend on the scavenging method.
Types of two-stroke engine are listed below :
- Crankcase Scavenged Engine
- Separately Scavenged Engine
The details of above two types of engine are describe below :
Crankcase scavenged engine :
It is one of the simplest types of two-stroke engine. In this engine the charge is compressed in the crankcase during the expansion stroke.
There are three ports in this engine :
- Intake port at the crankcase
- Transfer port
- Exhaust port
Through the transfer port compressed charge passes into the engine cylinder and flushing the products of combustion is called scavenging.
Separately scavenged engine :
It is same engine as crankcase engine but in this engine uses external device like a blower to scavenge the products of combustion is called externally or separately scavenged engine.
