LiquidPiston Develops New Rotary Engine That Promises to Revolutionize the Automotive Industry, Being Up to 5 Times More Powerful Than Existing Diesel Models in the Market.

The rotary engine is one of the most fascinating and innovative inventions in the history of internal combustion engines. However, it has some disadvantages such as high fuel consumption, low torque, high emissions, and complex lubrication. Despite these challenges, there are ways to overcome these limitations and create a new generation of rotary engines that can surpass conventional engines in the automotive industry.

LiquidPiston Rotary Engine Weighs Less Than 20 kg

Liquid Piston is the company developing and manufacturing the new rotary engine called X-Engine. It is a pistonless engine that operates on a patented thermodynamic cycle called high-efficiency hybrid cycle (HC).

Unlike conventional engines, the X-Engine uses a single rotor that performs both the compression and expansion of the working fluid, resulting in higher efficiency and lower emissions.

How the New Rotary Engine Works?

The company aims for about 20 kW and 29.4 Nm of torque, both at 6,500 Revolutions Per Minute. According to Liquid Piston, these numbers are comparable to the 18.8 kW and 63 Nm peak of the diesel engine coler KDW 13E 536A, which is approximately five times the physical size of the XTS 210 and more than four times its weight.

The design of the XTS uses only two main moving parts, a rotor and a shaft. The rotor has a trilobular shape that fits inside a housing with two lobes, creating three combustion chambers that go through the four stages of the HC cycle, namely intake, compression, power, and exhaust.

The shaft is connected to the rotor by a planetary gear system that allows the rotor to spin at a different speed than the shaft, optimizing the performance of the new rotary engine in the automotive industry.

In the XTS 210, the combustion chamber remains stationary and has a rounded shape. This design has a unique advantage, making it possible to achieve high compression simply by making the chamber smaller. Moreover, since the chamber does not move, it is possible to inject fuel directly into it, a feature that the Wankel engine could not offer.

Rotary Engine Expected to Hit the Market in 2024

What is truly remarkable is its versatility to run on a variety of fuels, including diesel, gasoline, hydrogen, and propane.

Currently, Liquid Piston is focusing on perfecting the new rotary engine with a specific emphasis on its compatibility with jet fuel JP8, which is of great importance in the defense and aerospace sectors.

A significant milestone in Liquid Piston’s journey is its recent contract with the United States Army, totaling a substantial amount of 9 million dollars.

This contract has raised its total earnings from military contracts beyond the impressive mark of 30 million dollars. With this new support, Liquid Piston is preparing to commercialize the new rotary engine, and we can expect the delivery of a prototype in 2024.

Rotary Engine Expected to Hit the Market in 2024

A giant half-ton ring fell in Kenya from space, and more than a year later, scientists still do not know where it came from.

Seen from space, an image taken by an astronaut shows an unlikely oasis in the Saudi Arabian desert, protected by a terrain that slows the advance of sand, surrounded by green circles, remnants of an extinct lake and nearly 10,000 years of preserved history.

In Botswana, a salt flat of up to 16,000 km² that was once an African megalake spends months as an absolute white desert, but during the rainy season it transforms into a shallow sea that reappears from nowhere and can be seen from space in the middle of southern Africa.

Bavarian archaeologists unearthed a medieval skeleton that had an articulated iron hand in place of its left arm, and the discovery reveals that doctors were already creating sophisticated prosthetics over 500 years ago.

Cell phones in schools: learn how a year after the ban, students and teachers are already noticing positive effects and recording improvements in academic performance with increased attention and active participation.

With 1,000 buses sent abroad, the Brazilian manufacturer consolidates the strength of national technology and takes on a leading role in public transportation across all of Latin America.

More than 1,500 Chinese workers transformed an entire railway station in just one night and reduced a 7-hour journey to 90 minutes with a high-speed line of 200 km/h.

Brazilian city becomes a global destination after attracting tourists who travel up to 10,000 km to visit a sanctuary with 11 giant saints up to 10 meters tall, open 24 hours and located along a highway in SP.

JBL Flip Essential 3 SE is launched with 30W of power (20W + 10W), Bluetooth 5.4, Auracast for multiple connections, IP67 water and dust resistance, up to 12 hours of battery life, and a price of approximately R$ 660 in China.

After ten days orbiting the Moon, science confirms that the astronauts of the Artemis II mission return with altered bodies.

Pernambuco paradise with 59% of preserved area advances with R$ 2 billion in e-methanol, aims for 900 tons/day, grows 38.6% and builds electrified terminal of 400 thousand TEUs.

Brazil may have railways back on the map, but it will need the government: a study reveals 7,412 km ready for reactivation, a cost of R$ 75 billion, 61 sections analyzed, and none viable without public funding.
