NX Animation Designer;4 cylinder Bourke Engine; 4기통 프로펠러 엔진

1920년대 Bourke 라는 사람이 특허낸 4기통 엔진 실린더 컨셉을 모델링 해봤습니다.
크랭크 샤프트 왕복 직선운동기구를 응용한
기본적으로 2 stroke 엔진입니다.
초창기 프로펠러 비행기 엔진으로 사용했던것 같은데 슬라이드부 마모로 크게 확산되지는 않는 방식이라고 합니다.
다음번에는 9기통 Radial propeller 비행기 엔진을 올려보겠습니다
구독, 좋아요 해주시면 많은 힘이 되겠습니다^^

The Bourke engine was an attempt by Russell Bourke, in the 1920s, to improve the two-stroke engine. Despite finishing his design and building several working engines, the onset of World War II, lack of test results,[1] and the poor health of his wife compounded to prevent his engine from ever coming successfully to market. The main claimed virtues of the design are that it has only two moving parts, is lightweight, has two power pulses per revolution, and does not need oil mixed into the fuel.

The Bourke engine is basically a two-stroke design, with one horizontally opposed piston assembly using two pistons that move in the same direction at the same time, so that their operations are 180 degrees out of phase. The pistons are connected to a Scotch Yoke mechanism in place of the more usual crankshaft mechanism, thus the piston acceleration is perfectly sinusoidal. This causes the pistons to spend more time at top dead center than conventional engines. The incoming charge is compressed in a chamber under the pistons, as in a conventional crankcase-charged two-stroke engine. The connecting-rod seal prevents the fuel from contaminating the bottom-end lubricating oil.
