摘要： PROBLEM TO BE SOLVED: To inhibit deterioration of environmental performance of an internal combustion engine caused by an excessive fuel injection quantity in start. SOLUTION: ECU 100 executes start injection control process to determine a fuel injection quantity of first cycle in starting in each cylinder of an engine 200. In the process, an intake stroke rotation speed R is estimated for each cylinder and a cylinder flow-in rate Crate_o which is a ratio of fuel flowing into a cylinder is determined for each cylinder, based on the intake stoke rotation speed R. Moreover, a base injection quantity Mbase is corrected based on the cylinder flow-in rate Crate_o to set a base cylinder flow-in quantity Cf evenly determined for each cylinder by cooling water temperature Tw and fuel properties Fp at a cylinder flow-in quantity Cf_o actually flowing in each cylinder. Consequently, the optimal fuel injection quantity M of the first cycle in starting is determined for each cylinder, and fuel equivalent to the fuel injection quantity M is injected to an intake air port 213 by an injector 214 in the first cycle in starting.

摘要： PROBLEM TO BE SOLVED: To reduce the foreign sound from an intake manifold surge tank by arranging a net in a part of an intake passage cross section in the downstream and vicinity of a throttle valve, and arranging a plurality of current straightening plates extending in the direction parallel to the intake passage axial core in a part of the remaining part. SOLUTION: This intake foreign sound reducing structure comprises a net 1 provided in a part of an intake passage cross section and a plurality of current straightening plates 7 provided in at least a part of the part having no net 1 of the intake passage cross section. The net 1 is provided in the part to which the flow carried through the clearance between the part brought down on the upstream side of a throttle valve 2 in opening and a passage wall 8 is collided, so that the turbulence of the flow can be reduced and the generation of the vibration of the passage wall 8 and generation of the foreign sound can be suppressed. Further by installing the current straightening plate 7, whereby the flow carried through the clearance between the part fallen on the downstream side in opening and the passage wall 8 is prevented from being dispersed in lateral direction when carried to the part of the current straightening plates 7, so that the turbulence of the flow is hardly caused.

摘要： PROBLEM TO BE SOLVED: To effectively prevent an air flow noise generated when a throttle valve is rapidly opened without giving a bad influence to an engine. SOLUTION: In just the downstream of a throttle valve 3, a guide means of intake flow, for instance, like a cylinder 5 is provided. Here, when the throttle valve 3 is opened, a first formed fast intake flow in the downstream of clearances 7, 8 is allowed to flow through a peripheral part of the cylinder 5, to be isolated from a slow intake flow in the central part, generation of flow turbulence is prevented. Since a plurality of intake flows of different flow speed and pressure, after straightened by the guide means like the cylinder 5, are smoothly merged in the downstream end, flow turbulence is suppressed, generation of air flow noise is prevented. The guide means may be formed in circular arc shape and flat plate shape provided with only a part necessary for separating an intake flow, an escape part avoiding a movable range of the throttle valve 3 may be provided.
