Internal-combustion engine
Document Type and Number:
Japanese Patent JP6079814
Kind Code:
B2
Abstract:
An internal combustion engine where a tumble flow is generated inside a combustion chamber includes: a spark plug; an in-cylinder injection valve that injects fuel at a specific timing so that a fuel spray proceeds towards the vortex center of the tumble flow at the time of stratified charge combustion operation; a variable tumble flow device for making the strength of a tumble flow variable; and a control device configured, when the spray penetration force of fuel injected by the in-cylinder injection valve is increased due to a change over time of the internal combustion engine, to close the variable tumble flow device during the stratified charge combustion operation.
