Abstract

หน่วยการดูดของเครื่องยนต์แบบสูบเดี่ยว ลูกสูบวางในแนวนอนและ มีการฉีดน้ำมันเข้าห้องเผาไหม้โดยตรง ที่จงใจทำให้เกิดการ หมุน เป็นวงของอากาศที่ดูดเข้า โดยวิธีใช้ช่องไอดีแบบโค้งเป็น ก้นหอย โดยที่ประการแรก ช่องไอดีถูกขึ้นรูปเป็นรูปตัวอักษรเอส (S) โดย ที่ท่อนกลางของมันนั้นตรงและทอดยาว สำหรับเพิ่มแรงเฉื่อย ให้กับ กระแสอากาศที่ดูดเข้ามา โดยที่ไม่ต้องเพิ่มความกว้างของฝา สูบ และประการที่สอง ท่อนตรงกึ่งกลางของช่องไอดีที่ขึ้นเป็นรูป ตัว อักษรเอสนั้น ถูกขึ้นรูปโดยทำให้เกิดความนุ่มนวลต่อเนื่อง เข้า กันท่อนที่โค้งเป็นรูปก้นหอย ดังนั้นกระแสของอากาศที่ถูก ดูด เข้าช่องไอดีจะไม่ถูกทำให้อ่อนกำลังลง และจะถูกนำร่องโดย ร่อง ทางเดินอากาศรูปก้นหอยให้หมุนวงไปเป็นมุมประมาณ 180 องศา ภาย ใต้ความเร่ง ก่อนที่มันจะเคลื่อนเข้าสู่ห้องเผาไหม้ และการ หมุน เป็นวงอย่างมีกำลังที่ถูกทำให้เกิดขึ้นนี้ก็จะเกิดต่อ เนื่องไป จนมันเคลื่อนเข้าไปสู่ศูนย์กลางของห้องเผาไหม้ 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

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. Has been placed under the zero point The middle of the combustion chamber thereof and The center of the air inlet was set above. The center of the combustion chamber is very high.

3.Air suction unit with a curved air intake, as per claim 1, consists of one top mounting hole. And mounting holes on the side One bottom hole is in the aforementioned cylinder head in the left and right axle sides. Each side above And which the intake channel consists of the first part Extending from the air inlet to the center, the first part is located near one of the mounting holes and the cylinder head consists of a horizontal center axis. Where the mounting holes are located It consists of sides that are near the horizontal central axis. With the side far from the horizontal axis And the first part is loud It was made to bend around the nearby side. With such a horizontal central axis
