Movement of the pistons of the AEQUEO thermal eco-engine

Aequeo Now propulsion technology aims to distribute, on a planetary level, vehicles with a low ecological footprint, respectful of the climate and the planet and able to meet the essential mobility needs of the populations and economies of the world. The sustainable synergic propulsion it offers combines a high-efficiency and high-effectiveness thermal eco-engine, a robust and light vehicle cell and clean carbon-neutral fuel. Compared to those of conventional thermal or electric vehicles, the overall impacts on the environment and resources are reduced by 50-70% per km driven, while usage costs are significantly lower.

Thermal engine with high efficiency and effectiveness

With a unique design, both economic and ecological, the AEQUEO thermal eco-engine brings together for the first time all the known and proven conditions for improving the efficiency of thermal engines: optimal combustion conditions, dual geometry of the chambers (Atkinson), continuously variable compression ratio, free sliding of the pistons – with the advantages of reduced fuel consumption and reduced pollutant and CO2 emissions. Simple, comprising only a small number of parts, subject in addition to low mechanical stresses, achieving a perfect balance of forces and moving masses, and avoiding any technological sophistication, it is also more compact, light and advantageous than any other heat engine. Offering conditions of reliability and a service life comparable to those of a conventional heat engine (sealing of the chambers, lubrication of moving parts, cooling), it is also easy to assemble and maintain.

At equal performance, the weight, size, cost, fuel consumption, pollutant emissions and CO2 emissions of the AEQUEO thermal eco-engine are reduced by 30-40% compared to those of the conventional thermal engine 2010.

Synergistic coupling

To the direct effects exerted by the engine on the ecological footprint (impacts on the environment and resources during the life cycle) and on the conditions of use of the vehicle, the sustainable synergic propulsion adds the indirect effects resulting from a coupling with the following elements:

  • Robust and light vehicle cell: Reducing the weight of the vehicle cell (chassis, bodywork, running gear) and extending its lifespan significantly reduce weight, fuel consumption, CO2 and pollutant emissions. and the cost of using the vehicle per km driven.
  • Clean fuel with carbon neutrality: The replacement of fossil fuel by a synthetic fuel with clean combustion, resulting from ambient CO2 and solar radiation by a thermo- or biochemical process, makes it possible to further reduce the emissions of CO2 and pollutants of the vehicle.

The combination of the above elements decreases the ecological footprint of the vehicle by 50 – 70% (up to 85% for CO2 emissions) as well as its running costs, compared to those of the conventional combustion vehicle.

Compared to conventional propulsion technologies, sustainable synergistic propulsion offers the advantage of a marked reduction in the need for resources and environmental impacts on the places of manufacture and recycling of vehicles as well as of production and distribution of the energy consumed. Its low environmental impact on the places where vehicles are used make it suitable for contributing, like electric propulsion, to the pollution control of cities.

Although its internal efficiency (“tank-to-wheel”) does not match that of electric propulsion, sustainable synergistic propulsion offers significantly higher overall efficiency (“well-to-wheel”). Not requiring a battery, it makes it possible to build vehicles that are lighter and more economical, with greater autonomy and lifespan, and whose manufacture and recycling require smaller amounts of energy and generate less environmental pollution. In addition, its use does not depend on a power supply network or the charging time of a battery.

Preserving the climate and the planet

The CO2 emissions and the ecological footprint of vehicles equipped with a thermal eco-engine powered by solar fuel and a sustainable synergistic propulsion are between 2.2 and 2.4 times lower than that of vehicles with conventional thermal propulsion or renewable electricity (between 1.7 and 2.3 times lower if solar fuel is replaced by fossil fuel). These advantages are reflected in the sustainability of the vehicles.

Its exceptional carbon balance, reduced ecological footprint and high sustainability – as well as its wide accessibility and low environmental impact on the places where vehicles are used – mean that the sustainable synergic propulsion with thermal eco-engine contributes more effectively than any other propulsion technology to preserve the climate and the planet.
