Two-stroke engine with direct fuel injection - has induction port below exhaust port and deflector lands provided on piston crown

摘要

The engine works on the two stroke system with direct fuel injection (3). Engine bearing lubrication is by force pump and wet sump. Ignition can be by high tension spark (2) or compression. The air intake (7) ports are arranged in the cylinder wall opposite to and below the exhausts ports (4). The piston crown is provided with lands at the edge to deflect the incoming air towards the cylinder head. The air is injected via a turbo charger and assists in expelling the exhaust residue.
