We cannot give tax advice, and we encourage you to talk with your accountant or tax advisor before making an investment. We are focusing on small package because there is strong demand for a very small compression ignition engine. Because a liquid can conform to an irregular chamber volume, the surface area to volume ratio in the gas chamber can be maximized using a liquid piston. For the X Mini 70 cc spark-ignited prototype, the compression ratio is 9:1. They lost $26 million to generate $10 million in revenue. This, once more, comes mostly from government contracts.. Diesel cycle): For maximum efficiency, air is compressed to a high compression ratio, fuel is injected and compression is ignited (CI-HEHC). We have a peanut-shaped (trochoidal) rotor within a tri-lobed-shaped housing. The basic idea is similar to a Wankel rotary, but turned on its head. Engineers have been trying to make engines smaller, lighter, and more efficient for decades, but LiquidPiston was the first in a century to go back to . This cycle consists of compressing air (with no fuel) to a very high ratio, as is typical in the Diesel cycle. The formula for calculating the output power of an electric driver is: P_S\ =\ 1.732\times V\ \times I\ \times PF\ \times Motor\ Efficiency\times Coupling\ Efficiency.

That alone could dramatically lower the price of hybrid EVs, truly making them accessible. Despite these advantages, the Wankel was always plagued by poor fuel economy, emissions problems, and durability issues, especially in the apex / tip seals. A liquid piston gas compressor facilitates high-pressure compression, and efficient convective heat transfer can significantly reduce the compression energy consumption during air compression. [1][2] Its because the profits drop, and it has yet to create a product ready for the market in nearly two decades. The required seals (both face and apex) are mounted on the stationary housing, and are lubricated directly. This paper investigates the . 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).
