MUMBAI, India, June 6 -- Intellectual Property India has published a patent application (202517048818 A) filed by Jcb Research, Uttoxeter, U.K., on May 20, for 'four-stroke gaseous fuel engine.'
Inventor(s) include Mccarthy, Paul; Vickery, Warren; Vowles, Richard; and Appella, Louis.
The application for the patent was published on June 6, under issue no. 23/2025.
According to the abstract released by the Intellectual Property India: "A four-stroke gaseous fuel engine comprising one or more cylinder assemblies, each cylinder assembly comprising : a cylinder including an inlet and an outlet selectively opened and closed by an intake valve and an exhaust valve respectively; a piston translationally movable within the cylinder;an intake runner leading to the inlet; and a fuel injector. The cylinder assembly is configured to selectively inject a gaseous fuel from the fuel injector into the intake runner. The engine is configured to supply gaseous fuel and air from the intake runner to the cylinder via the inlet during an intake stroke of the piston, and exhaust combustion gases from the cylinder via the outlet during an exhaust stroke of the piston. Within a four-stroke cycle of the engine, the cylinder assembly is configured to inject the gaseous fuel into the intake runner exclusively during an interval starting with a first crank angle of the piston and ending with a second crank angle of the piston. At a maximum interval that the cylinder assembly can inject the gaseous fuel into the intake runner, the first crank angle corresponds to the intake valve being closed and the exhaust valve being open during the exhaust stroke, and the second crank angle corresponds to the intake valve being open and the exhaust valve being closed during the intake stroke."
The patent application was internationally filed on Oct. 27, 2023, under International application No.PCT/GB2023/052815.
