Design and development of piston-controlled intake port for 4-stroke engine

In a two stroke engine, piston control the intake port opening and closing that combine the intake and compression stroke in 1800 crank rotation. The operational concept of two stroke engine is applied to the existing four stroke engine cylinder head. The four stroke engine cycle is more fuel-effici...

The operational concept of two stroke engine is applied to the existing four stroke engine cylinder head.
