Specific to the company, its worth noting that while rotary engines feature fewer moving parts, there are reasons why this platform is not the industry standard. Thank you! The difference in the X engine is the side seals can be lubricated through access points in the cover, which is a unique feature of this engine. Eaton Corporation | arpa-e.energy.gov This has three effects: cooling the engine, reducing NOx emissions, and converting some of the water to steam, which increases power. In addition, it can run on Jet A fuel, the fuel choice of the military, unlike other engines of the same size. LiquidPiston | The Future of the Combustion Engine Research contracts and consulting make up the majority of their income. Its X1 engine is a simple machine with just three moving parts and thirteen major components, but it aims to raise thermal efficiency from the 20 percent of a normal gas engine to more than 50 percent, with drastic reductions in weight and size. Answer (1 of 5): In practice it is very similar to the Wankel engine in the way that it operates, so has many of the same benefits and downsides. Moreover, LiquidPiston has integrated its engines into drones, which offers tremendous flexibility and capacity for military applications. Discontinued News All rights reserved. With lower pressure exhaust and just two moving components that are optimally balanced, the engine is inherently quiet, and offers exceptionally low vibration. The required seals (both face and apex) are mounted on the stationary housing, and are lubricated directly. Answer (1 of 2): Liquid Piston's X Engine is a non-Wankel rotary engine that is a further enhancement to a High Efficiency Hybrid Cycle (HEHC).
