Claims
- 1. In a turbo-charger arrangement for a two cycle, crankcase compression, multiple cylinder internal combustion engine comprising an exhaust chamber for receiving exhaust gases from the cylinders, an exhaust system including an exhaust pipe extending from said exhaust chamber, an expansion chamber, said exhaust pipe discharging into said expansion chamber for receipt of said exhaust gases from said exhaust chamber and a turbo-charger having a turbine stage inlet and exhaust, the improvement comprising said turbine stage inlet being in direct communication with said exhaust chamber for driving the turbine from the exhaust gases in said exhaust chamber.
- 2. In a turbo-charger arrangement as set forth in claim 1 wherein the exhaust gases are delivered to the expansion chamber from the engine chambers through an elongated pipe extending into the expansion chamber.
- 3. In a turbo-charger arrangement as set forth in claim 1 wherein the turbine stage exhaust discharges exhaust gases directly to the atmosphere and not through the expansion chamber.
- 4. In a turbo-charger arrangement as set forth in claim 1 in combination with an outboard motor including a power head containing the internal combustion engine, a drive shaft housing depending from the power head and adapted to contain a drive shaft driven by the output shaft of the engine and a lower unit depending from the drive shaft housing and adapted to drive an associated watercraft.
- 5. In a turbo-charger arrangement as set forth in claim 4 wherein the expansion chamber is positioned within the drive shaft housing.
- 6. In a turbo-charger arrangement as set forth in claim 1 further including valve means for controlling the flow of exhaust gases through the exhaust pipe from the exhaust chamber into the expansion chamber.
