For more than 100 years, the internal combustion engine has not seen any fundamental technological breakthroughs. Large, heavy and inefficient engines are common, and they tend to use a lot of fuel in operation. Modern diesel engines are particularly cumbersome, fuel-efficient, and in many cases excessively noisy. Liquid piston Compared with traditional gasoline and diesel-powered designs, the X engine provides a greater range and reduces greenhouse gas emissions, while also providing size and weight advantages over most competitors. Investing in this exciting technology can help it achieve its goal of changing the application market, which will require more efficient use of fossil fuels, while transitioning to biofuels and increasing electrification.

LiquidPiston solved the limitations of these traditional internal combustion engines (ICE) by inventing a new optimized thermal cycle and rotary engine platform. The thermodynamic cycle determines how much of the energy contained in the fuel can be converted into useful work output, while the rest is wasted as heat. LP’s proprietary thermal cycle, called High Efficiency Hybrid Cycle (HEHC), has a maximum theoretical thermal efficiency that is approximately 30% higher than that of Otto (gasoline) and diesel cycles in the 1800s. With higher thermal efficiency limits, LP has proven that its X-Engine can achieve higher fuel efficiency than piston engines of the same displacement or horsepower.

The world is vigorously promoting the electrification of automobiles, especially in the automotive field. This brings performance and noise reduction advantages, but adds a large and heavy battery that needs to be carried and recharged. The energy density of fossil fuels is still 40 times that of today’s best batteries, so obtaining the benefits of electric propulsion in many applications has economic and performance significance, but the batteries are much smaller and can be increased by a small vehicle during operation. It burns fuel to drive a generator.

Essentially, the fuel carried by the vehicle has a higher energy density than the battery and can be converted into electrical energy. In addition, refueling is achieved through the currently widely deployed gasoline/diesel fuel distribution system. LP has been focusing and will continue to focus on advanced combustion, engine platform design and engine operation innovation, with more than 60 granted and pending patents. The innovation includes an elegant and compact design with only two main moving parts: the shaft and the rotor. The X-Engine rotor has a simple structure, which reduces the number of parts and the amount of metal used. Because there are no pistons and valves, it runs quieter and has much lower vibration compared with piston engines.

LP engine development investment Will contribute to its continuous development and application design. Currently, the company focuses on the military and aerospace environments, but they plan to enter the industrial, commercial and automotive markets later. If you are interested in engine technology and its various applications and advancements, cheering for them and contributing to the development of LiquidPiston may make you satisfied.
