+부품(파츠)+ RCV(Rotating Cilinder Valve) motor

[베이베기린(김상수)]

The TWO WHEELS WITH TOW to THEM Between the series of not conventional motors that could arrive in production in the next few years are also motor RCV (Rotating Cilinder Valve, valve to rotary cylinder), relative not too much far away of the motors with sleeve valves employed on the hunting of the second world war. Draft in this case of an apt technology above all to the rolled small (in fact has already been employed on some motor model aircrafts), but that the ideatore Keith Lawes would want to extend to the field of the two wheels. Interest for this solution has been shown from taiwanese constructor PGO, always interested to the technologies alternatives. Thanks to the interest of dottor the Chih-tsao Chen, in charge of the R& D of the House, we can now make the point on the development of the plan. Motor RCV would have, in the PGO intentions, to place side by side and to even replace the 50 and 125 cc destined ones to the scooter of the next years. If version 50 already in is advanced phase of experimentation, the most ambitious 125 are meeting some difficulty to catch up the prefixed standards of performance.

PRECEDNTI technology RCV is an evolution of that of the sleeve valves. Practically, in motor RCV to the place of the classic valves (`to fungo') there is a rotary cylinder that alternatively opens and closes the lights of admission and drainage. In the years already Eighty licence GV Technology had shown of being able to exceed the classics problems of held problematic lubrication and of that they plagued these solutions, with the conversion of a Yamaha XT 500 that did not have some continuation in spite of the interesting reduction of consumption (- 30%) caught up. Motor RCV wants to be the definitive answer, thanks to a brave principle - to make to rotate the shirt of the cylinder - and to a diamond intuition - an floating estate that compensates or the thermal expansions that the production tolerances.

AS the PGO interest WORKS the RCV is comprehensible, because the RCV has various characteristics that render it interesting for a scooter. The relationship between the gears is such for which the spin of the cylinder it happens to speed halved regarding that of the drive shaft and the crank: motor RCV is thus in a position to also realizing a cycle to 4 times with typical elements of the 2T, like note the fixed lights (the holes of aspiration and drainage that are plugged or opened from the piston, rather than from a valve like in the 4T). The fact that the power taken one can happen from an element that rotates to speed halved regarding the drive shaft facilitates the job of the CVT and of it increases the yield. With the exception of a distribution to valves and motivatings force, then, the system to rotary cylinder absorbs a power lowland (not is aces to cams neither motivatings force of contrast) and almost constant to varying of the number of turns and is therefore perfect for a motor from scooter to shifter, that it works nearly always in regime of the maximum brace.

와.. 표에 보면 RCV가 일반 밸브 타입보다 파워도 좋고, 무게도 가볍고 친환경적이며, 연비도 좋게 나와 있군요... RCV가 실제 어떤 차에 적용 되어 있습니까..?

[#98류승완]

citi100 ㅋㅋㅋㅋㅋ

[던파전사]

이해가 잘 안가는데....로터리 엔진하고 비슷하다고 생각하면 되는건가요`` 아닌가``

[우양ㅋㅋ굳ㅋ]

로터리엔진과는 전혀틀리구요, 일반 피스톤엔진의 흡배기방식인 밸브개폐방식이 아닌, 실린더헤드 윗부분이 회전하면서 흡배기타이밍에 맞게 뚤어진 구멍으로 슬라이드 개폐되는 방식이라 보시면 되겠네요ㅋㅋ

멋진 기관이군요. 참으로 완성도 높은 기관같습니다. 우선 벨브 라고 표현 해야 맞는지 모르겟지만. 일반 벨브 같은경우엔 상하 운동으로 열렸다 닫혔다 하지만. 이 기관 같은경우엔 . 벨브 가 회전운동을 하면서. 흡기 쪽 으로 오픈 되고 닫히면서 압축 하고 역시 닫힌 상태로 폭팔 배기 쪽이 열리면서 배기가 되는 기관으로 보임니다.

[호주이보]

장점으로는 현제 사용하는 헤드벨브 기관처럼 연소율을 줄이지 않으면서 고회전 성을 얻을수 있는 것으로 보입니다.

[호주이보]

잘만 사용된다면 단기통 이나 2기통 기관 오토바이에겐 혁신적인 기관이 아닌가 쉽습니다. 개인 적인 생각으로는 3기통이나 4기통 은 힘들지 않나 쉬습니다.

[뱅봉삼]

CATIA V5로 설계된 듯? ㅋ

[시드]

요즘 희안한 엔진 많이 나오는군요^^ OHC 엔진의 한계를 뛰어 넘는 엔진이 나왔으면 합니당
