Modern engines waste a lot of energy. Much of the fuel’s heat is lost through exhaust gases and cooling systems, and combustion often happens too quickly and inefficiently. This not only wastes fuel but also creates air pollution.
This invention, the External Burner Engine, addresses these issues with a new design that burns fuel more completely and makes better use of the heat produced. Instead of burning fuel inside the engine, this system uses an external burner to mix fuel with an auxiliary fuel (like air or another gas) and burn it thoroughly before sending the hot gases into a pneumatic motor—a device that converts gas pressure into mechanical motion.
What sets this invention apart is how it captures and reuses heat. It uses heat exchangers and heat pumps to absorb waste heat from the exhaust and engine body. This recycled heat is then used to preheat the incoming fuel, boosting efficiency without using extra energy. A control valve fine-tunes the timing and flow of gases, ensuring optimal pressure is used throughout the process. An insulation shell reduces heat loss even further.
The key innovation here is shifting combustion outside the engine and layering multiple energy recovery systems to minimize waste and maximize fuel use.
Tangible benefits include
- Better fuel efficiency
- Lower emissions and pollution
- Extended engine life due to reduced internal heat stress
Broader impact
This engine could reduce fuel costs for industries and transportation, help cut global emissions, and contribute to cleaner air—all without requiring radical changes to existing fuel infrastructure. In short, this invention presents a smarter, cleaner way to run engines by rethinking where and how combustion happens.
