【発明の名称】内燃機関の混合気形成装置
Document Type and Number:
Japanese Patent JP3107489
Kind Code:
B2
Abstract:
An air-fuel mixture supply apparatus includes an intake passage opening to a combustion chamber in a cylinder, an intake valve provided between the intake passage and the combustion chamber, a fuel injection valve for injecting at least one of branched spray flows directing to the intake valve, a swirl generator generates vortex flow in the mixture in the combustion chamber by controlling to choke the intake passage. The swirl generator comprises a main passage forming the intake passage, at least one of sub-intake passages which is provided to form a by-pass passage of the main passage and formed such that the total sum of the cross-sectional areas is smaller than the cross-sectional area of the main passage, an intake control valve for controlling the choke of the main passage, a valve for controlling the choke at least one of the sub-intake passages, a controller for varying the number of the sub-intake passages to be used and the cross-sectional area of each of the sub-intake passages corresponding to the operating state of the internal combustion engine, and another controller for varying the direction of fuel injection and the number of fuel injections corresponding to the operating state of the internal combustion engine.
