The 25-horsepower XTS-210 adds up to one bar of boost through supercharging and operates as a two-stroke, producing six combustion events per revolution of the rotor, to deliver smooth power from a lightweight package, roughly the size of a basketball.<\/p>\n\n\n\n<p>The XTS-210 uniquely addresses four major market requirements:<\/p>\n\n\n\n<ul>\n<li><strong>5x the power-to-weight<\/strong>&nbsp;(specific power)<strong>&nbsp;and<\/strong>&nbsp;<strong>power-to-volume<\/strong>&nbsp;(power density), and&nbsp;<strong>up to 3x the torque-to-weight<\/strong>&nbsp;(specific torque) compared with diesel&nbsp;piston engines of similar power<\/li>\n\n\n\n<li><strong>Ultra-portable and configurable for operation in both engine-only and hybrid-electric modes \u2013&nbsp;<\/strong>capable of running up to 7,000 RPM, which matches well with small and lightweight electrical machines, enabling increased mobility for power generation and hybrid applications<\/li>\n\n\n\n<li><strong>Liquid-cooled and capable of either Spark-Ignition (SI) or Compression-Ignition (CI) \u2013&nbsp;<\/strong>designed for military-grade robustness from its inception<\/li>\n\n\n\n<li><strong>Multi-fuel capability \u2013&nbsp;<\/strong>initial testing focuses on&nbsp;<strong>JP-8\/Jet-A fuels<\/strong>&nbsp;for defense and aerospace applications<\/li>\n<\/ul>\n\n\n\n<p>The XTS-210 model will meet demanding commercial and military heavy-fuel applications, including mobile electric power generation, primary or hybrid-electric propulsive power for vertical take-off and landing aircraft (VTOL) and small unmanned aircraft systems (sUAS), as well as auxiliary power units for land, air, and marine vehicles.<\/p>\n\n\n\n<p><em>\u201cThere are essentially no diesel engines in the 25-horsepower power class today that are suitable for aerospace and mobile military applications, where size and weight parameters are especially critical,&#8221; said&nbsp;<\/em><strong><em>Dr.<\/em><\/strong>&nbsp;<strong><em>Alec Shkolnik, co-founder and CEO of LiquidPiston.<\/em><\/strong><em>&nbsp;&#8220;<\/em><em>The reduced weight, size, and heavy- or multi-fuel capability of the XTS-210 delivers significant end-system capability and utility benefits, especially for the military to reduce supply chain and logistical burdens in an era where \u2018power on the move\u2019 is increasingly important.&nbsp;<\/em><em>Following nearly two decades of breakthrough thermodynamics research with various types of rotary diesel engines, we are excited to converge on this latest generation as our first X-Engine model that we plan to bring to market.\u201d<\/em><\/p>\n\n\n\n<p>LiquidPiston is targeting delivery of an XTS-210 prototype to the U.S. Army in 2024. The company has previously prototyped several variants of rotary X-Engines, demonstrating significant versatility in engine architecture, including naturally aspirated four-stroke versions ranging from five to 40 horsepower.<\/p>\n\n\n\n<p>In addition to the recent $9 million award to contribute to the development of the XTS-210, LiquidPiston has also received a $1.7 million Army contract to power a hybrid-electric VTOL UAV demonstrator. This brings the company\u2019s Department of Defense contracts total to over $30 million.<\/p>\n\n\n\n<p>To view additional photos and other assets, please visit the LiquidPiston media kit at:&nbsp;<a href=\"https:\/\/www.globenewswire.com\/Tracker?data=i-RePJYnlJbcyt0wKn2GPmMnQ52mKwMCWScPmdmhkQO6s9AK32VQewpBOp2u-lXPJiI1jbzprgvzAo1VCzRRmv7LU71WQuclZUnEKaLfCtxAJoZma4VPkoil51Tr_urGMg5gzE7B98M1fTg2XX_rOg==\" rel=\"noreferrer noopener\" target=\"_blank\"><u>https:\/\/www.liquidpiston.com\/xts-210-engine<\/u><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>LiquidPiston, a leading innovator of compact and efficient engine technology and hybrid power systems, today announced the company\u2019s intent to commercialize the XTS-210, a 25-horsepower, two-stroke, supercharged, liquid-cooled, 210cc rotary engine.
