摘要
<p>The engine has three engines and crank shafts arranged in an engine block made of light metal. A propeller is firmly connected with the center crank shaft. The upper and lower crankshafts are connected over a guide roller with a V-belt, so that the force from the crankshafts is transferred to the propeller. The engine is made from light metal material. A channel with different diameter is embedded at openings in piston head.</p>
