TH1441B - The curved intake port is the volute of the intake unit for single-cylinder diesel engines, horizontally placed and injected directly into the combustion chamber. - Google Patents

Abstract

Single cylinder engine suction unit The piston is placed horizontally and Oil is injected directly into the combustion chamber. that deliberately causes a circular rotation of air that is sucked in By using the curved intake vent as a spiral, where first The intake vents are molded into the letter S (S), with the middle part being straight and elongated. For adding inertia force to the incoming air stream. without having to increase the width of the cylinder head and secondly The middle section of the intake port, formed in the shape of the letter S, is molded to create a smooth, continuous, scalloped shape. Therefore, the stream of air sucked into the intake port is not weakened. and will be piloted by a spiral airway groove to rotate approximately 180 degrees under acceleration before it enters the combustion chamber and this vigorous orbital rotation that has been created will continue. continued until it moved into the center of the combustion chamber.

Claims (4)

1. Air intake unit with curved air intake vents. For the machine Center-mounted single-cylinder diesel combustion chamber Medium and there is a direct injection of oil in a horizontal line where the suction unit Such includes - Cylinder head with a vertical shaft And it consists of a wall. In a vertical location facing the combustion chamber with the outer wall opposite the inner wall and at least one vertical side wall. - Intake valve opening And the opening of the exhaust flap that is located close to each other in the said inner wall. The opening of the intake valve consists of a peripheral edge and a vertically distant center in the first vertical direction from the center of the combustion chamber. - air inlet provided in the side wall The air inlet consists of a second vertical center, opposite the first vertical, from the center of the combustion chamber. - Intake channel that is curved in a spiral like "S" serves to connect. The air inlet is attached to the opening of the said intake flap. The intake port consists of a center that is linear and extends vertically within the cylinder head, with the said center located on the side of the core. It is also limited by the inner and outer walls, with the inner wall closer to the core than the outer wall, and the inner wall is attached to the edge while the outer wall can be attached. It is connected to a curved wall that serves as the front arc of the intake, and the wall has been made to approach the edge in sequence until it is attached to it. Which the connection of the curved wall It is closer to the core than the attachment of the inner wall. 2.Air suction unit with a curved intake manifold as per claim 1 at the center of the opening of the said intake flap.
