81-Year-Old Inventor Creates Crankless Engine That Promises to Revolutionize the Automotive Industry by Reducing Fuel Consumption and Carbon Emissions.

The automotive sector is constantly evolving, driven by the search for more eco-friendly and much more efficient solutions. Among the latest innovations in the sector, the creation of a crankless internal combustion engine has stood out.

The invention was the result of much study and effort by an elderly Frenchman named Maurice Saint-Germain, who is 81 years old. This technology has the potential to stand out in this market by reducing fuel consumption and carbon emissions while maintaining energy efficiency.

The Innovation Behind the Crankless Engine

Maurice Saint-Germain, from Denée, France, developed a crankless thermal engine, an innovation protected by a registered patent at the French National Institute of Industrial Property in 2015.

Less Friction, More Efficiency

In conventional thermal engines, the crank-connecting rod system generates lateral friction in the cylinders, reducing efficiency.

With Saint-Germain’s design, this problem is overcome thanks to a rotating plate that supports the cylinders, accompanied by a central and eccentric pinion system that converts the pistons’ motion.

This design significantly reduces friction, resulting in lower fuel consumption and lower pollutant emissions.

Potential for Various Applications

Besides its application in the automotive sector, the technology developed by Saint-Germain can also be employed in pumps and compressors, expanding its impact to other areas of industry.

The inventor is currently seeking partnerships with companies to enable the construction of a functional prototype, which could accelerate the adoption of this innovative technology.

What Is the Purpose of the Crankshaft?

The crankshaft is an essential component of the internal combustion engine, responsible for converting the linear motion of the pistons into rotary motion. This component consists of bearings, arms, and counterweights that work together to transform the force generated by combustion into mechanical energy.

Directly connected to the connecting rods, it receives the back-and-forth motion of the pistons and converts it into rotation, allowing the force to be transferred to the transmission system and, consequently, to the vehicle’s wheels.

Its robust construction is crucial for withstanding the intense pressures and forces generated during engine operation.

In addition to its main mechanical function, the crankshaft plays an important role in the engine’s balance and smoothness. The counterweights help reduce vibrations, providing a more stable operation.

Environmental and Economic Impacts

By reducing friction and fuel consumption, the crankless engine directly contributes to lowering the carbon footprint.

This innovation aligns with global sustainability goals, favoring the transition to cleaner vehicles. Moreover, greater energy efficiency can reduce operational costs, benefiting consumers and businesses.

Despite its enormous potential, the viability of the technology still depends on the construction of a functional prototype and large-scale testing.

However, Saint-Germain’s innovation paves the way for new approaches in thermal engine design, challenging paradigms and encouraging further research in this field.

Environmental and Economic Impacts

Gaddafi built the world’s largest artificial river under the Sahara — it’s 4,000 km of giant pipes that pump 40,000-year-old fossil water to entire cities in Libya.

Discovery in Africa scares even scientists: a study published on April 23 reveals that the crust in Turkana has become so thin that it could pave the way for the continent’s division and the emergence of an ocean in the future, in a gigantic geological transformation.

Austria inaugurates Europe’s first high-speed railway outside China — trains travel at 250 km/h through 33 km tunnels in the Alps that took 27 years to drill

An unmanned Russian ship has been drifting in the Mediterranean for 57 days with 60,000 tons of gas — the second towing attempt has just failed.

2 scientists analyzed in a new study whether the construction of a mega dam in the Bering Strait could be the last barrier against climate collapse, to protect one of the world’s most important ocean currents.

An MIT startup is betting on superhot geothermal in Oregon and building the world’s first plant of its kind, targeting rocks above 300°C to generate 50 MW by 2030 and expand the project to 250 MW with few wells.

5 wolf-in-sheep’s-clothing cars that hid absurd mechanics, from a sedan with a Ferrari V8 and a Toyota with a twin-turbo 2JZ to a Saab wagon that gave Porsches a run for their money and the brutal Lotus Carlton disguised as an Omega

End of the 6×1 work schedule could expand women’s access to the labor market, says minister, linking a shorter workweek, two days of rest, and combating the overburdening of women to greater dignity and equal pay in the country.

Women experience a “7×0 schedule” in care work, dedicating almost 10 more hours per week to home and family, and sustaining an invisible routine that extends across holidays, weekends, and mental health.

Smart bin in London tracked pedestrians’ cell phones, used WiFi to measure urban circulation, raised a privacy alert, and showed how a simple bin can become a street spy.
