MUMBAI, India, July 30 -- Intellectual Property India has published a patent application (202641085400 A) filed by Manipal Academy Of Higher Education on July 13, 2026, for A System And Method For Controlling Start-Of-Injection Timing In An Ethanol-Hydrogen Dual-Fuel Engine.
Inventors include Aditya Thapa; Akshat; Jibitesh Kumar Panda; and Jayashish Kumar Pandey.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: A system (100) for controlling start-of-injection timing in a gasoline direct injection engine operating on an ethanol-hydrogen dual-fuel mode comprises an intake system supplying hydrogen to an intake port (101) through a flow control valve, a direct fuel injection system injecting liquid ethanol fuel into a combustion chamber (103), one or more engine sensors generating engine operating parameters, and an engine control unit operatively coupled thereto. The engine control unit regulates hydrogen flow, controls a start-of-injection crank-angle position during an intake stroke, acquires combustion performance parameters comprising brake specific fuel consumption, carbon monoxide emission, unburned hydrocarbon emission, and nitrogen oxide emission across a plurality of start-of-injection crank-angle positions and hydrogen flow rates, and determines and applies a start-of-injection crank-angle position satisfying predetermined combustion performance criteria.
