【発明の名称】内燃エンジン
Document Type and Number:
Japanese Patent JP2002504646
Kind Code:
A
Abstract:
An internal combustion engine has an inlet port side angle (B) which is greater than 60° and is preferably 101°±3°. The exhaust valve side angle (C) is preferably 93°±3°. The inlet valve seat (3) is located closer to the longitudinal axis (8) of the cylinder than the exhaust valve seat (4) and the imaginary line (16) which passes through the geometric centres of the valve seats (3, 4) is offset from the diameter (7) of the cylinder. This combination of characteristics gives an engine having a high specific power output, low specific fuel consumption, low emissions of carbon monoxide and unburnt hydrocarbons and a cool exhaust gas containing a significant volume of oxygen.
