튜브플 자체 업로드 기능 부분 활성화,


2.0 기능 일부 적용,


모든 데이터 베이스 이전 작업으로 많은 소요시간이 필요합니다.


양해 부탁드립니다.

More engines. Bigger ones. Enjoy!

00:00 V8: 8-Cylinder V-Engine
01:04 U12: Twin-Straight-6 U-Engine
02:38 H16: 16-Cylinder H-Engine
04:38 X24: 24-Cylinder X-Engine
06:11 42-Cyl 7-Row Radial-6 Engine
09:49 S100: Straight-100 Engine
11:34 side-by-side and sound comparison

Note: In real life the U12 and X24 have 3-throw crankshafts (pistons are 120 degrees apart) and the 42-cyl has a 6-throw crankshaft. Those are a bit complex to do with Lego so I used simpler 2-throw cranks (180 degrees). Thus firing orders are not correct in those engines. Also the 42-cyl Zvezda M503 was done with radial-6s instead of the real life radial-7s because I couldn't find proper Lego parts for connecting pistons to the crankshaft. The Sherman 6046 U12 engine gearing and phase offset between the shafts were unknown to me so I just guessed them to be 1:1 and 90 degrees. In other ways the models should be correct (hopefully). The V8 has a flat-plane crank that were used in Formula One engines. Lotus 46 H16 flat-plane crank, gearing and phase between the shafts should be correct according to the schema image I found (shown in the video). The U12 has both crankshafts rotating to the same direction as was explained in mapleleafup forum.
