Document Type and Number:
Japanese Patent JP4346049
Kind Code:
B2
Abstract:
To provide an engine with a valve resting function for resting at least one of a plurality of intake valves when the engine is in a specific operational region, which is capable of preventing the flow-in of the remaining fuel in a combustion chamber when the rested intake valve is switched to be opened/closed, thereby preventing the reduction in engine output and the increase in unburned hydrocarbon. A communication passage is provided in a cylinder head for enabling a fuel-air mixture to flow from an intake passage corresponding to an intake valve in a resting state to an intake passage corresponding to an intake valve in a resting state, when said engine is in a specific operational region.
