Generator Engine Dimensions

This is part of a project where I take an ordinary generator engine and modify each part to show what differences they make in terms of performance. The goal is to turn a 3HP engine into something quite crazy. In order to do this I must first measure up every single part of an engine, this is that page. The next page will be building a rig to test performance in terms of RPM, torque and power.

Note that I chose not to explain how I measured each individual part, it's pretty self-explanatory. I used a 6 and 12 inch caliper along with a scanner in order to map all of the measurements. The scanner is very useful to map profiles but requires some kind of a scale for reference. You will see in the pictures that I set a caliper to 150mm and placed the anvil points sharply onto the scanner glass. I found I could get an extremely accurate measurement with this method, almost to what the caliper stated. This engine is made in China and quite clearly metric despite all of the documentation with it being in imperial. I found that nearly all of the measurements were nice round numbers or in gradients of 0.5mm which made it much easier to "assume" what the dimension should be. So for example measuring 47.03mm for a hole spacing is likely 47mm. Some of the geometries were really hard to measure and model accurately, so I focused more on dimensionally crucial aspects.

 

Currently under construction. Still left to measure, cam shaft, crank case, head, valve cover, starter, exhaust, air filter box and shroud.
