The present invention relates to a structural arrangement for a stationary internal combustion engine for machines or vehicles (universal), which can use various types of fuel. More specifically, the present invention relates to an internal combustion engine with improved combustion efficiency, improved thermodynamic efficiency, reduced dimensions, an improved power-to-weight ratio that exceeds that of aircraft turbine engines using the Brayton thermodynamic cycle, and up to three times less fuel consumption and gas emissions into the environment.
