Abstract

Page 1 of 1 page Summary of the invention To provide an intake device for an internal combustion engine to increase combustion efficiency. It is best suited by modifying the strength of the tumble vortex through the generation of a strong tumble vortex in the loaded state. Low and suppression of intake air flowing through the upper passage in medium/high load state. The intake distribution valve (65) has a disc-like valve body (67) that extends habitually. Same from the rotating shaft (66), the rotating shaft (66) will align the direction of the center of rotation (Cv) of the rotating shaft. in parallel with the downstream end edge (61aa) of the divider plate (60) and is connected to rotatable with inlet pipe (20) positioned close to the area under the upstream end edge (61aa). The intake distribution (65) will allow a plate-like valve body (67) or a plate-like valve body (67) and a rotating shaft (66) to close the opening on the upstream side of the lower intake passage ( Lp) when the engine burns The internal is in a low load operation state.

Claims (3)

Disclaimer (all) which will not appear on the advertisement page: page 1 of the number 2 pages 1. an internal combustion engine input device in which the combustion chamber (40) is formed between the top surface of the piston (25) that is assembled. Movable design in the cylinder bore (16b) of the cylinder block (16) and the ceiling surface (41) of the cylinder head (17) opposite the top surface of the cavity. The inlet (44) and the exhaust port (45) have been formed respectively. It extends from the intake valve opening (42) and the exhaust valve opening (43), which opens to the ceiling surface (41) of the cylinder head (17) while keeping the curve in the direction from each other. Continuous inlet pass (P) is formed by connecting inlet pipe (20) to inlet (44). Throttle valve (22) is provided. In the inlet pipe (20), the input pass (P) is partially divided by the dividing plate (60) into the upper intake pass (Up) connected to the central part of the combustion chamber. (40) and the lower intake pass (Lp) connected to the outer circumference of the combustion chamber (40) the intake distribution valve (65) has been established. Provided on the side The end of the throttle valve (22) and at the side of the separator plate (60) in the inlet pipe (20) for controlling the ratio of the intake air flow between the upper intake pass (Up) and The lower intake pass (Lp) and the propulsion action of the intake manifold distribution valve (65) are regulated with the unit. The intake control (71) wherein the inlet distribution valve (65) includes the plate-like valve body (67), which extends uniformly from the rotating shaft (66), the rotating shaft (66). Align the axis of rotation (Cv) of the rotating shaft in parallel with The forward edge (61aa) of the spacer baffle (60) and is rotatable coupled to the inlet pipe (20) while being positioned near the area under the vestibule edge. (61aa) Inlet distribution valve (65) allows the plate-like valve body (67) or plate-like valve body (67) and pivot shaft (66) to close the opening on the side of the passageway. Lower input (Lp) Since the internal combustion engine is in a low load operation state, page 2 of the number of 2 discs, the split (60) is rebuilt in such a way that Each end of the dividing plate (61) on the side of the inlet pipe (20) provided with the inlet pipe (20) and the separator plate (62) on the side of the inlet pipe. Been provided with the inlet (44) overlapping each other and The coupling has been connected to each other, the end opposing end (62b) of the dividing plate (62) on the side of the recessed inlet. The recessed portion (62 o) is a U-shaped recessed portion from the leading edge, valve guide (34i) extending into the inlet port (44 ) Passes through the concave basin (62 N), and the input distribution valve (65) is formed with an intermediate passageway (Mp) connected to the lower entrance (Lp). ) Between the lower obverse surface of the guide end (61a) of the dividing plate (61) on the side obverse of the inlet pipe and the notched recess (65d) of the rotating shaft (66) when the valve body, which is Sheet (67) is separated from the lower obverse circumference of the inlet pipe (20) to open the lower entrance obtrusive opening (Lp). 2. The input device of the internal combustion engine according to claim 1, where the dividing plate (60) divides the input pass (P) in such a way that the area of the pass-through of the upper entrance pass (Up) smaller than the passage area of the lower entrance pass (Lp) 3. The internal combustion engine input device according to claim 2, where the rotating shaft (66) of the intake distribution valve (65) is coupled to the point where the spindle line (Cv) intersects a perpendicular center line (Cp) into the center trajectory of the maximum vertical width. Of the entrance pass (P)
