The X-Mini engine has gone through initial durability testing and has been tested in a customer prototype, which was demonstrated in an on-field application. You see, while combustion engines have been around longer than the sands of time, that is also in itself an asset. Its because the profits drop, and it has yet to create a product ready for the market in nearly two decades. And we also upgraded its cycle to give it much higher efficiency." The X-Engine's ability to eliminate bulk and weight is extraordinary; to give you an idea, the team pulled a 40-lb (18-kg), 6.5 . The company is focusing on military and aerospace markets, whose propulsion and . This creates near-isothermal operation, which minimizes energy lost to heat generation. Can an engineer change the world? Here, the company takes an old platform the rotary engine and implements groundbreaking thermal efficiency improvements. And this runs counter to the concept of combustion engines. A 1D engine model (GT-POWER) and a 3D CFD model (CONVERGE), were coupled together with the objective of quantifying the engine heat transfer losses inside the combustion chamber. The optimized thermodynamic cycle has the potential to decrease fuel consumption by 30%, thereby lowering CO2 emissions and the cost of running an engine. Sure, every once in a blue moon, youll come across a grand slam. Here's why LiquidPiston's new engine technology is catching the attention of researchers and engineers everywhere and why investors should tune in as well. LiquidPiston is presently developing its 5th generation engine architecture, with prototype development of the X-Engine and application demonstrators, largely funded by DoD contracts. This is mainly because 1) the Wankel requires clearance at the corners between its side/face seals and its apex seals, while the X engine does not; and 2) the Wankel seals traverse across holes that contain spark plug(s), whereas the X engine does not. 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. The engine has exceeded the mechanical verification target, demonstrating stable operation with in-cylinder pressures of 150 bar. The liquid piston internal combustion engine of the invention utilizes a novel, synergetic combination of internal combustion and steam piston engines within the framework of one and the same system. A new spin on the internal combustion engine by startup LiquidPiston aims for a leap in efficiency from 20 percent to 50 percent.
