Abstract: PURPOSE: A continuously variable valve lift apparatus is provided to use in a V-type engine by making valve profiles of the continuously variable valve lift apparatuses, which are symmetrical, identical. CONSTITUTION: A continuously variable valve lift apparatus comprises an input cam(110), a follower supporting part(200), a follower(300), a linear guide(400), an output cam(500), and a valve opening/closing part(600). The input cam is installed on a cam shaft(100). The follower is supported by the follower supporting part. The location of the central axis of the follower is varied along the circumferential direction of the cam shaft. The follower reciprocates around the central axis by being delivered with the rotation of the input cam. The output cam is contacted with the follower and reciprocates along the linear guide. The valve opening/closing part is opened and closed by being contacted with the output cam. The follower supporting part is formed in the cam shaft to be rotated.

Abstract: Disclosed are a variable intake manifold for an internal combustion engine and a variable air intake device using the same. The variable intake manifold includes an intake port through which external air flows; first and second outlet ports through which the external air fed via the inlet port is discharged via different passages; a partition dividing a part of a first intake passage extending from the inlet port to the first outlet port and a second intake passage extending from the inlet port to the second outlet port into an upstream passage and a downstream passage. The lengths of the partitions positioned in the first and second intake passages are set to be different, and a port flap valve device for opening or closing the downstream passage is provided to form tumble flow and swirl flow which are strong against the intake air fed to the combustion chamber.

Abstract: 본 발명은 전동식 진공펌프의 구조를 개선하여 경량화 및 부피를 콤팩트화할 수 있도록 한 것이다.
본 발명은 외부의 전기적 신호에 의해 동작되는 전동 모터부와, 전동 모터부의 모터축과 연결되어 흡입된 공기를 펌핑 동작으로 압축시켜 배출하는 펌핑부와, 외주면에 외부 공기를 흡입하는 흡입구와 펌핑부에서 압축된 공기를 배출하는 배출구가 배치되고 압축 공기를 댐핑하여 소음을 저감시키는 흡음부로 구성된다.
이에 따르면 본 발명은 흡입구와 배출구를 흡음부에 배치하고 마운팅 플레이트를 삭제함으로써, 부품 수 감소로 인해 경량화 및 콤팩트화되고 원가를 절감할 수 있을 뿐만 아니라, 분해 및 조립성이 향상되는 유용한 효과를 갖는다.-

Abstract: PURPOSE: A continuous variable valve lift apparatus is provided to reduce pumping loss of a cylinder by advancing the maximum lift point as the valve lift decreases. CONSTITUTION: A continuous variable valve lift apparatus comprises a control shaft(105), an eccentric member, a roller type follower(155), and a variable arm. The control shaft is arranged in a line with a cam shaft(100) formed with a cam on one side. The eccentric member has an insertion hole in which the control shaft is inserted and an eccentric circumference having a center eccentric from the center of the inner circumference of the insertion hole. The roller type follower is installed on an end of a follower arm extended from a follower loop and contacts with the cam. The variable arm is extended from a variable loop(150) which is installed to slide on the eccentric outer circumference and moves toward or opposite to the center of the control shaft according to the rotation of the control shaft, thereby changing the amount or timing of pressing a swing arm(125).
