  • Method and apparatus for increasing the efficiency of internal combustion engines
    Patent number: 5339632
    Abstract: This invention relates generally to a system for increasing the thermodynamic efficiency of internal combustion engines. In the system of the invention, the unused heat generated during normal engine operation in the exhaust gases, lubricating oil and engine coolant is utilized to compress air which produces additional energy that performs additional work in the engine system by means of a modified Rankine cycle. This same system used to maximize efficiency and increase power also acts to reduce pollutants in the exhaust emissions.
