Company Reveals Innovative Diesel Rotary Engine, With Potential to Be Up to Five Times More Powerful and Efficient Than Conventional Piston Engines.

Developed by Felix Wankel in 1924, the rotary engine marked a milestone in vehicle history, but, like any innovation, faced significant challenges. Among them are high fuel consumption, pollutant emissions, lower torque, and complexities in lubrication. To overcome these obstacles, Liquid Piston is developing the X Engine, a new diesel rotary engine. This innovative approach promises to enhance rotary engine technology, addressing its historical limitations.

Advantages of the New Rotary Engine Developed by Liquid Piston

Among the advantages of this new rotary engine are its lightweight design, as it is 75% lighter and smaller than the currently used AMMPS. It is also easier to transport, as it can be portable rather than requiring a truck, trailer, or forklift.

The rotary engine is also efficient in terms of space, occupying only 9 cubic feet. Finally, it is more fuel-efficient, designed to use up to 8% less fuel. Due to its compact and lightweight nature, its power density is 5 times greater compared to a piston diesel engine.

Engine Developed with Focus on Military and Commercial Applications

The supercharger XTS adds up to 1 bar of boost while operating in a two-stroke cycle, generating 6 combustion events per rotor rotation, to provide smooth power from a small package.

The new rotary engine is designed to meet the demanding commercial and military applications of heavy fuel, including mobile electric power generation, primary electric or hybrid propulsion for vehicles, including vertical takeoff and landing (VTOL) aircraft and small unmanned aircraft systems, as well as auxiliary power units.

Among the benefits to unmanned aircraft are:

Silent operation mode (only electric “silent” cruise);
Almost zero vibration;
Operates with JP-8 and other aviation fuels;
Flight duration up to 60% longer;
Transition from electric cruise back to engine power with in-flight engine restart.

Possible Return of Diesel Engines

The CEO of Ford, Jim Farley, recently announced the launch of a revolutionary diesel engine, called the Powershift Titan, which has the potential to transform the competition with electric cars. This new diesel engine from Ford stands out for its extraordinary efficiency compared to traditional internal combustion engines, featuring incredibly low carbon emission levels, never before seen in the industry. The brand’s boldness is announced at a time when electric vehicles seem to be leading the automotive market.

The new Ford diesel engine is innovative, built with advanced materials and modern combustion technologies. The powertrain shines for its efficiency, with various fuels, including biofuel, thus expanding its market and reinforcing its ecological profile.

The impact of Ford’s announcement goes beyond passenger models. If the new diesel engine can be applied on a larger scale, including trucks, it could slow down or even reverse the use of electric vehicles in those segments.

Engineers want to carve through Africa with a giant canal to bring water from the world’s second-largest river to a dying lake on the edge of the Sahara Desert that has already lost 90% of its water.

A giant brown band visible from space, approximately 8,850 kilometers long, connected Africa to America in the Atlantic Ocean, and satellites revealed that it is neither land nor pollution, but the largest accumulation of seaweed in the world, which broke records in 2025.

Brazil filled the Northeast with wind turbines but now faces the side effect of 705 giant blades reaching the end of their lifespan by 2032 just in Rio Grande do Norte, while the world projects 43 million tons of waste by 2050.

Instead of burning or burying old tires, an American city is transforming about 2,000 of them into the street itself, paving its first sections with a quieter and more durable rubber asphalt.

In just one cast, fishermen are surprised to capture 14,096 mullets in Bombinhas and close a historic season with 58,000 fish; scene recorded in the Santa Catarina paradise marks the last day of the 2026 season.

10 giant tortoises are reintroduced and, in just 6 months, trigger changes that lead scientists to investigate a phenomenon absent for 180 years; the numbers recorded on the island impress researchers from around the world.

Greek island offers free housing for volunteers, but there’s a condition: you need to take care of rescued cats.

A former SpaceX engineer left rockets to reinvent home construction and founded a startup that manufactures wall panels from a grass that grows about 15 centimeters per day.

He transformed an abandoned plastic water tank into an underground house in the “hobbit hole” style, using only repurposed pallet wood, without heavy machinery or expensive labor.

How much does it cost to install gutters in a house in 2026? See the average costs of materials, labor, and the most common extra expenses that may arise during installation.

The United States government approved a potential sale of 100 portable Stinger anti-aircraft missiles to the Brazilian Army, in a package estimated at around 330 million dollars that still depends on negotiations between the two countries.

Cheaper than Fiat Pulse, Renault Kardian, and Volkswagen Tera: with a 2.0 turbo engine of 190 hp, 30.6 kgfm torque, automatic transmission, and Swedish safety package, this premium hatch delivers sports car performance at the price of a new compact: meet the Volvo V40 T4 Momentum 2017.
