Sure, every once in a blue moon, youll come across a grand slam. Unlike the Wankel however, there are several key differentiators which address the bulk of the older Wankels design deficiencies:The combustion chamber in the X engine is located in the stationary housing, with most of the gas displaced during compression into this stationary combustion chamber. Also, it will be ten years before an electric jet is ready, and even then, it will be a while before they are widely used. Hydrogen is the sixth fuel variation that has been proven to power the X-Engine along with gasoline, propane, kerosene, diesel, and jet A fuel. They are the rotor and the shaft, which are perfectly balanced. First engine innovation in a century. You can read more about this exciting development on the companys StartEngine equity crowdfunding profile. The rotor has passages to supply air and remove exhaust gas, thereby eliminating the need for valves. It has a fundamentally different architecture and operation.The Wankel rotary engine demonstrated excellent power to weight characteristics and exhibited low vibration even at high RPM. This creates near-isothermal operation, which minimizes energy lost to heat generation. 1. The air is then isolated in a constant volume chamber. Thank you! In the Wankel, the only successful pistonless rotary engine to date, an oval-like epitrochoid housing surrounds a curved sided triangular rotor.
