LiquidPiston has rethought the engine starting with first principles - revisiting the thermodynamic cycle - and innovating in a space that hasn't changed in over 100 years! Typical piston diesel engines use between 15:1 and 24:1. The X-Mini is a 70cc air-cooled naturally aspirated four-stroke X-Engine variant, that has been operated on a variety of fuels using spark ignition including gasoline, kerosene, jet fuels including Jet A, as well as propane and hydrogen .[4]. Its even though everyone ages away from an exit. LiquidPiston's current aim is to continue developing the engine with an eye on the sub-100 hp marketcompressors, hybrid range-extenders, military applications, boat enginesand license the intellectual property to manufacturing customers. All rights reserved. The X-Engine is spartan and quieter since it only has two main moving elements. For example, drones previously couldn't use jet fuel, so the military had to set up an entire supply chain just for gasolene fuel. This is to pawn the shares to the unwary via social media marketing. Droplet heat transfer in liquid piston has shown a significant advantage in creating near-isothermal compression with a high compression efficiency [18]. 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. Leboeuf, M., Dufault, J., Nickerson, M., Becker, K. et al., Performance of a Low-Blowby Sealing System for a High Efficiency Rotary Engine, SAE Technical Paper 2018-01-0372, 2018, https://doi.org/10.4271/2018-01-0372.The X-Engine overcomes the gas leakage issue of the Wankel engine by using two axially-loaded face seals that directly interface with three stationary radially-loaded apex seals per rotor. Why did LiquidPiston already get millions in Department of Defense (DoD) contracts? They have lost $26 million in investor money in less than 20 years. Not only that, it can make engines ten-times smaller and lighter promoting . Hence, despite increasing losses, they increased their valuation to $184 million, more than doubling it. Altogether, they've developed diesel engines and small gasoline engines alike, in addition to fuel injection and engine control systems. LiquidPiston's Small Tactical Power Generators provide more than an 80% . This allows significant reduction in oil consumption over a regular rotary motor. Moreover, with an optimum inlet pressure of liquid piston, the round-trip efficiency and exergy efficiency were achieved to be 62.6% and 55.4%, respectively, in actual operating conditions. Today, they not only have an opportunity to invest in a startup, but one preparing to shake up a $400B global industry. 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. And while its not as sexy as solid-state batteries, the value to why you may want to invest in LiquidPiston stock is that this technology is proven. Battery-powered electric vehicles have challenges on the path to a renewable future. These challenges are due to a number of inherent issues: 1) a narrow combustion chamber prevents adequate flame propagation, while also having high surface to volume ratio which cools the charge and reduces efficiency; 2) the engine is poorly sealed, leading to significant blowby, thereby decreasing efficiency; 3) the Wankel engine operates on the same conventional 4-stroke Otto cycle with spark ignition as a piston engine; however there are inherent challenges to operate > 10:1 compression ratio, and this engine was forced to compete with piston engines that had over one hundred years of prior development; and 4) the tip seals, in addition to being difficult to seal, are also difficult to lubricate; oil must be injected into the charge, with the majority of the oil burned in order to lubricate the gas seals.The X engine essentially inverts the Wankel engine. The improvement in efficiency is lower with the use of 16 wires/inch mesh showing the efficiency of 86-89%. LiquidPiston, Inc., of Bloomfield, CT, recently signed an agreement with the U.S. Defense Advanced Research Projects Agency, better known as DARPA, to use the hyper-efficient rotary engine .
