This short video clearly shows the relationship between crankshaft, conrods and cylinders for the rotary engine. In rotary engines the crankcase rotates with the propeller. The conrods rotate about the crank pin. These two rotational axes are parallel and half the length of the stroke apart. In this way the early engines removed the need … Read more
The idea was to build a small 5 cylinder rotary engine that runs on compressed air, the crankcase for the five cylinder rotary would be another challenge. This is a rotary engine where the crankcase rotates with the propeller and the crank remains stationary. The main image shows my initial sketches. I will try and … Read more
Whilst walking around the Shuttleworth Collection I came across a display cabinet with a number of engines built by Les Chenery. The I thought I just have to add a post and share the images of these wonderful working model engines. Details of how you can still get drawings for these models are available on … Read more
There are so many different configurations of internal combustion engine that have been developed through the history of engines that I thought I would try and list them in some vague order – based on increasing number of cylinders and complexity: Single Cylinder – Horizontal The first internal combustion engines were single cylinder designs … Read more
This 5 Cylinder Rotary engine took some years from start to finish, a number of those years were down to us moving house and me not locating it after the move. The engine is approximately 85mm in diameter with the cylinder heads attached. As this is a rotary engine, the crankshaft is fixed and the … Read more
