[33] demonstrated at high pressures from 0.7 MPa to 21 MPa that the efficiency and power density of liquid piston C/E could be increased by adding a porous medium to increase the heat transfer area, and that the location of the porous medium approximately near the top of the chamber had a more pronounced effect on the C/E gain. But the implications of LiquidPiston's X-Engine reach farther than just any new widget: it could set off another industrial revolution, the company says. The X4 engine has been tested on our dynamometers to develop high speed compression ignition strategies for all future LiquidPiston compression ignited engines. In addition, it can run on Jet A fuel, the fuel choice of the military, unlike other engines of the same size. You can help Wikipedia by expanding it. Thus, they give clients access to small, effective combustion engines that can run on various fuels. LPI's technology could be critical in addressing a possible lithium shortage. It is compared to $2.6 million in revenue and a $1.8 million loss in 2021. Not only does that save fuel, but lets the drone quietly move into sensitive areas with advanced capability. The co-ordination of the power strokes of the cylinders and the selective . 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. However, the moment where EVs make up a significant portion of the global automobile market may be a long time coming. InvestorPlace - Stock Market News, Stock Advice & Trading Tips. Alexander Shkolnik, Nikolay Shkolnik, Mark Nickerson et al., Compact, lightweight, high efficiency rotary engine for generator, APU, and range-extended electric vehicles, 2018 NDIAGround Vehicle Systems Engineering and Technology Symposium, Aug 7-9, 2018, Novi, MIThis paper will overview the HEHC thermodynamic cycle and rotary X engine, and will describe the development status of the X4, a 0.8L Compression Ignition engine, funded by the Defense Advanced Research Projects Agency (DARPA), with aggressive targets including: 30 kW power, and power to weight of 1 hp/lb Operating on the HEHC cycle, the X4 engine can potentially achieve very high brake thermal efficiency of up to 45%. Thanks to LiquidPiston's proprietary technology, though, the company claims it can improve efficiency by 30%. LiquidPiston is the developer and manufacturer of a pistonless rotary engine called the X-engine, located in Bloomfield, Connecticut. Liquid Piston has a lengthy history of using crowdfunding to raise money. Absolutely! Tiago J.

Despite what individual companies may promise, theres always the chance of losing a portion, or the entirety, of your investment. DARPA has awarded LiquidPiston Inc. $2.5 million to continue development of a new, patented, high-efficiency, lighter-weight rotary engine. LPI has developed two core technologies, a patented thermodynamic cycle and our patented X-Engine. Fair. National attention and fascination with their technology, in addition to their potential to disrupt military and consumer engines, adds wind to the sails. Since its start in 2003, Liquid Piston has been operating. This innovative rotary engine architecture shows a potential indicated efficiency of 60% and brake efficiency of >50%. The pump power is supplied by an electric motor. Altogether, they've developed diesel engines and small gasoline engines alike, in addition to fuel injection and engine control systems. [3] This would generally rule out the use of low octane fuels like gasoline, so there is also a lower compression spark ignited version called the X-Mini. And the improvement in this ready-made platform is what drives the narrative for LiquidPiston stock. By getting the same power with up to a 10X smaller engine, were opening up possibilities for air taxis. Their primary sources of income are government research grants and consulting contracts. LiquidPiston, Inc (LPI) has developed a compact, efficient rotary engine architecture (the "X" Engine) which operates on an advanced, fuel-optimized thermodynamic cycle. The intake and exhaust ports and chambers . The company is focusing on military and aerospace markets, whose propulsion and . This is the best concept we have ever heard. We have no idea what the adjusted valuation will be for this raise. Buildings; . LiquidPiston has developed engine prototypes that range from 3 to 40HP: X-Mini: 70 cc (3-5 HP) Multi-Fuel Spark-Ignition HEHC engine X4: 750 cc (40 HP) Diesel Compression-Ignition HEHC engine. We have a peanut-shaped (trochoidal) rotor within a tri-lobed-shaped housing. A simple, efficient and elegant system, the X Engine only has a few moving parts, including the rotor (the primary work-producing component) and an eccentric shaft. Insiders observed the businesss status and believed they deserved yet another $7.5 million payoff. Our patented X-Engine solves the problems of the rotary engine without sacrificing the benefits. Up to 80% smaller and lighter than the traditional piston Diesel engines. Yes, for direct or hybrid electric propulsion for Unmanned Aerial Systems (UAS), and as Auxiliary Power Units (APUs) or Supplemental Power Units (SPUs) for larger manned fixed-wing aircrafts and rotorcrafts. They will increase the amount of internally supported R&D and technology demonstration they do. @misc{etde_21177773, title = {Liquid piston gas compression} author = {Van de Ven, James D, and Li, Perry Y} abstractNote = {A liquid piston concept is proposed to improve the efficiency of gas compression and expansion. Although an efficient combustion-engine car could theoretically stem the tide of the mainstreaming of EVs, theres just one problem: typically, technology moves societies forward, not backward. Accelerating the electric revolution: We reinvented the internal combustion engine and provide optimized hybrid power solutions for generators and vehicles - making hybrid systems smaller, lighter, cheaper, and more accessible.In the future, we envision our hybrid power systems using low-to-zero carbon fuels such as hydrogen. Jeep Gladiator discontinued: Will there be a 2023 Gladiator? For LiquidPiston, that translates to building off the rotary engine and improving its efficiency for the enhancement of both electric and combustion cars. The 30 kW size may be of significant interest in the automotive application as a range extender for Electric Vehicles. In addition, as the internal combustion engine market is transformed by lighter, smaller, more efficient technology, markets like agriculture and industrial equipment will be disrupted in turn. The Shkolniks themselves have won a Society of Automotive Engineers "best paper" award for their research. This has three effects: cooling the engine, reducing NOx emissions, and converting some of the water to steam, which increases power. The minimum investment size for this current round is $1,000. In this study, an interrupted plate porous media is used to enhance the heat dissipation during compression and improve the compression efficiency in ionic liquid piston compressors. Methods, devices, and systems for power generation through liquid piston internal combustion engine. The companys technology uses various thermodynamic cycles, topologies, and operations. This unlocks a 100% green energy solution for the combustion engine market. The basic idea is similar to a Wankel rotary, but turned on its head. Methods for scaling include: 1) changing the diameter of the rotor; 2) changing the width of the rotor; or 3) adding more rotors. LiquidPiston 30kW Generator concept (11 on left) vs. 30kW AMMPS genset (2 on right) means more generators per pallet - a game changer for the military. We can get products out to the military market because of their national security power requirements and we expect to leverage those application use cases and X-Engine designs to participate in a variety of vehicle (including land vehicles) hybrid electric propulsion applications using a range of fossil and low carbon fuels in the future. LiquidPiston is a company that develops combustion engines. This, once more, comes mostly from government contracts.. The optimized thermodynamic cycle has the potential to decrease fuel consumption by 30%, thereby lowering CO2 emissions and the cost of running an engine. There are still some applications available.
