摘要： An engine in which the cylinders are each provided with a first intake valve, a second intake valve and an intake passage common to the first and second intake valves. The intake passage is divided into a central passage and two side passages located on each side of the central passage by two side separating walls, which extend from the valve stem guides of the first and second intake valves toward the upstream of the intake passage. The downstream end portion of the central passage is divided into two branch passages. Each of the branch passages is in communication with the corresponding side passage via an opening formed in the corresponding side separating wall. A fuel injector is arranged in the central passage, and a control valve is arranged in the central passage upstream of the fuel injector and opens when the engine is operating under a heavy load.

摘要： An engine comprising an intake port which has a separating wall projecting downwardly from the upper wall of the intake port. The separating wall defines a helical portion, an inlet passage portion tangentially connected to the helical portion, and a bypass passage interconnecting the inlet passage portion and the helical portion. The separating wall has an upstream end portion centrally located between the opposed side walls of the intake port. A rotary valve is arranged in the bypass passage and is actuated by a vacuum-operated diaphragm apparatus. The rotary valve is opened when the amount of air fed into the cylinder of the engine is increased beyond a predetermined value.

摘要： An engine comprising an intake port which has a separating wall projecting downwardly from the upper wall of the intake port. The separating wall defines a helical portion, an inlet passage portion tangentially connected to the helical portion, and a bypass passage interconnecting the inlet passage portion and the helical portion. The separating wall extends to near the side wall of the helical portion and defines a narrow passage portion therebetween. The width of the upper wall of the inlet passage portion is gradually reduced towards the narrow passage portion. A rotary valve is arranged in the bypass passage and is actuated by a vacuum-operated diaphragm apparatus. The rotary valve is opened when the amount of air fed into the cylinder of the engine is increased beyond a predetermined value.

摘要： A helical type intake port for an internal combustion engine. The system has a first sub-intake passageway and a second sub-intake passageway. The first sub-intake passageway is connected to a helical end of the intake passageway for generating a flow of air for suppression of the swirl effect in the helical end. The second sub-intake passageway is connected to a portion of the helical port located upstream of the helical end portion, for increasing the speed of flow of air directed to the helical end portion.

摘要： An internal combustion engine comprising a first raised portion formed on the inner wall of the cylinder head, a second raised portion formed on the top face of the piston at a position opposite to the first raised portion with respect to the axis of the piston, and a third raised portion formed on the inner wall of the cylinder head above the second raised portion. A first flat squish area is formed between the flat peripheral top face of the piston and the flat bottom face of the first raised portion. A second spherical shell shaped squish area is formed between the spherical bottom wall of the third raised portion and the spherical rear face of the second raised portion. The second raised portion has a front face which comprises a gently inclined front face portion and a steeply inclined front face portion. The gently inclined front face portion is arranged beneath the exhaust valve, and the steeply inclined front face portion is arranged beneath the intake valve.
