    摘要: An internal combustion engine having a combustion chamber divided into two regions by an arcuate barrier on the top of the piston and a complementary arcuate barrier formed in a cavity of the cylinder head. When the piston is at top dead center, the combustion chamber is effectively divided into two portions with approximately ten percent of the chamber being in the vicinity of a fuel injector and a spark plug. By this structure, the engine minimizes the amount of fuel used at idle and at very low power levels, and yet engine performance at higher power levels is not affected.

Operation of the valve is controlled by a control mechanism which is movable between an operating position and a non-operating position corresponding to the open position of the valve and is biased to the non-operating position by the spring.

    摘要: Disclosed herein is a marine propulsion device comprising a combustion chamber, an exhaust passage, an air pump and a three-way catalytic converter. The air pump pumps air into the exhaust passage at or immediately upstream of the catalytic converter. By this construction the internal combustion engine can be run slightly rich, but the catalytic converter will see a close to stoichiometric mixture so that the pollutants in the exhaust stream can be oxidized or reduced appropriately since the catalytic converter will be able to operate as a three-way catalytic converter.
