1. A method of using gas internal energy (thermal energy+kinetic energy) that is a product of cooling parts of system, or internal combustion engine, or exhaust gas which is product of burning fuels of any kind and especially fossil fuel such as:
- oil, gas, petrol, kerosene, diesel fuel, coal or others by;
a. flowing this gas through a nozzle which at least one part of said nozzle is a convergent nozzle which accelerates gas speed while the gas getting colder according to Bernoulli'"'"'s law for compressible flow, i.e., the gain of kinetic energy per unit mass Δ
V2/2, (V is gas speed) of the flowing gas, is equals to the decrease of gas thermal energy per unit mass;
CP*Δ
T, where CP is the gas constant pressure specific heat and Δ
T is the gas temperature decrease during acceleration inside the convergent nozzle;
b. either flowing the accelerated gas through a turbine that drives electrical generator that generates electricity, said electricity power is about equal to the decrease of flowing gas internal energy second and further ejecting this gas through nozzle exit to generate thrust, or, ejecting the accelerated gas into the atmosphere to create thrust opposite in direction to the gas speed or, combination of flowing the gas through the turbine and creating thrust to push a vehicle in a desired direction.

Abstract
A method of increasing internal combustion engine efficiency is based on using engine cooling air and exhaust gas by flowing this mixture into a convergent nozzle thus accelerating the gas mixture and eject it through nozzle exit, thus generating thrust in a desired direction which could push a land air or sea vehicle. Another option is to use the accelerated gas to drive a turbine that could add its torque to the engine or to drive electrical generator that produces electricity.
