Let me introduce you to the Rasant Twin 0.098 ccm Mk III diesel engine. The crank case was machined from bar stock and sand blasted. This engine is far smaller than the other 2 cylinder Rasant twins. We produced 2 of these prototype engines. Cylinders and spinner were anodized in blue. These engines had 2 intake and 2 exhaust ports. All of our multi cylinder engines have divided connecting rods held with two miniature screws.
