    摘要： In an intake system for a multicylinder engine, discrete intake passage portions immediately connected to the respective cylinders are divided into two groups so that intake timings of the discrete intake passage portions in each group are not immediately successive, and the discrete intake passage portions in each group are concentrated to form a concentrated portion. Branch intake passage portions extend upstream from the concentrated portions for the both groups and are integrated with each other to form a main intake passage portion. Bypass air for adjusting the engine rpm during idling, blowby gas from the crankcase, fuel vapors trapped by the canister, exhaust from the exhaust system and the like are introduced into the concentrated portions of the discrete intake passage portions or the branch intake passage portions by way of a fluid introduction passage comprising a pair of branch introduction passage portions which are connected to the respective concentrated portions at one end and to a downstream end of a main introduction passage portion at the other end. The main introduction passage portion is connected to sources of the fluids described above at the upstream end portion. The average length l and the diameter d of the branch introduction passage portions are selected to satisfy the conditiond/.sqroot.l

    摘要： A valve drive device for an engine include a valve for opening or closing an opening of a port to a combustion chamber, a valve drive member for opening or closing the valve and a drive shaft for driving the valve drive member. The device also includes a variable valve timing mechanism for continuously changing a working angle of the valve corresponding to an operation state of the engine by changing a state of drive force transmission from the drive shaft to the valve drive member. A variable valve clearance mechanism is configured such that a valve clearance that is defined as a gap between the valve and the valve drive member can be set at a first value during a first condition in which the working angle of the valve is large to a second different value during a second condition in which the working angle of the valve is small.
