Japanese Patent JP3562342
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve transportability of fuel spray to a circumference of an ignition plug and to restrain wall surface attachment of fuel. SOLUTION: It is possible to realize stabilization of stratified combustion and improvement of an exhaust characteristic as transportability of fuel spray is improved as atomization and vaporization of fuel is promoted and directivity to an ignition plug 9 is improved since a sequential tumble flow A of intake air formed in a combustion chamber 4 by a flow control valve 11 provided in an air intake port 7 is reinforced at the time of stratified combustion and reservability of the sequential tumble flow A is improved by a recessed part 13 of a side surface ω shape provided on a crown surface of a piston 2.
