MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202641024444 A) filed by Chennai Institute Of Technology, Chennai, Tamil Nadu, on March 2, for 'thermoelectric air preheating system for improving fuel efficiency in internal combustion engines.'
Inventor(s) include Mr. A. Muthu Kumaran; Dr. R. Sathiyamoorthi; Dr. J. Rajaparthiban; Mr. A. Parthiban; and Mr. P. Balamurali.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to a thermoelectric air preheating system designed to improve the fuel efficiency of internal combustion engines by utilizing the Peltier effect. The system comprises a thermoelectric Peltier module positioned between aluminum heat sinks, powered by a DC power source, and supported by dual cooling fans to control airflow. When electrical current is applied, the Peltier module creates a temperature gradient, generating heat on one side to preheat the intake air before it enters the carburetor or intake manifold. The preheated air enhances fuel vaporization, resulting in more complete combustion, reduced fuel consumption, and lower exhaust emissions. The system is compact, lightweight, and easily adaptable to two-wheelers and small petrol engines without major modifications. Experimental testing demonstrated an increase in fuel efficiency of approximately 8-10%, making the system a cost-effective and environmentally friendly solution for improving engine performance."
