MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202521119552 A) filed by Kirloskar Oil Engines Limited, Pune, Maharashtra, on Nov. 30, 2025, for 'a method for determining real-time torque of a genset.'
Inventor(s) include Kiran Raj Bukkarapu; Ajay V; and Abhijeet Y Vaze.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a real-time torque estimation system for diesel generator sets equipped with mechanical fuel injection systems and lacking an Electronic Control Unit (ECU). The invention provides a dual-path torque estimation method implemented in a Genset Control Unit (GCU), wherein a first torque is estimated from exhaust gas temperature (EGT) using lookup-table-based field torque and density-correction logic derived from manifold absolute pressure (MAP) and manifold air temperature (MAT). A second torque is computed from real electrical load using alternator efficiency, auxiliary loss data and engine speed. A cross-verification logic compares both torque paths, applies deviation thresholds and determines validity. Depending on sensor health and uncertainty values, the system generates an averaged or inverse-variance weighted final torque and transmits it over a Controller Area Network (CAN). The invention enables accurate torque reporting, diagnostics and subsystem control without requiring ECU retrofitting."
