MUMBAI, India, June 27 -- Intellectual Property India has published a patent application (202517053376 A) filed by Jacobs Vehicle Systems, Inc., Connecticut, on June 2, for 'system facilitating cylinder deactivation and 1.5-stroke engine braking operation in an internal combustion engine.'
Inventor(s) include Gron, Jr. G. Michael; Alexandru, Matei; Mandell, John; Bovat, Paul M.; and Baltrucki, Justin D.
The application for the patent was published on June 27, under issue no. 26/2025.
According to the abstract released by the Intellectual Property India: "A valve actuation system comprises a cylinder deactivation controller operatively connected to and in fluid communication with intake and exhaust deactivators for at least one cylinder. The valve actuation system further comprises an engine braking controller operatively connected to and in fluid communication with the engine braking actuators for the at least one cylinder. A braking-dependent deactivator controller is disposed between and in fluid communication with the cylinder deactivation controller and the intake deactivators, and in fluid communication with the engine braking controller via a control input. The braking-dependent deactivator controller is configured, in a first state based on its control input, to permit hydraulic fluid flow in hydraulic fluid control passages for the intake deactivators when in a non-1.5-stroke engine braking mode and, in a second state, to vent the hydraulic fluid control passages for the intake deactivators when in a 1.5-stroke engine braking mode."
The patent application was internationally filed on Dec. 05, 2023, under International application No.PCT/IB2023/062217.
