Preparation of gaseous fuel mixtures

The text examines the fundamental limitation of internal combustion engines—their inherently low mechanical efficiency—despite the near-perfect optimization of the fuel combustion process. While the reciprocating-to-rotary motion conversion mechanism remains the primary source of energy losses, numerous proposed technical alternatives have not yet gained sufficient investor interest. Modern internal combustion engines operating on the Otto cycle achieve up to 98% efficiency in extracting the chemical energy of fuel during combustion, largely due to advanced fuel delivery systems and highly optimized combustion chambers designed for constant-pressure combustion. However, the mechanical inefficiencies inherent in traditional motion conversion systems continue to restrict overall engine performance, creating a persistent technical contradiction that remains unresolved despite thousands of recent innovations in this field.
