Patent number: 11692465Abstract: An internal combustion engine includes an electro-hydraulic system for variable actuation of intake valves where each cylinder has two intake valves, associated with two intake conduits. A first conduit is generates within the cylinder a tumble motion of airflow introduced therein, when the intake valve associated thereto is at least partially opened. The second intake conduit generates within the cylinder a swirl motion of airflow introduced therein when the second intake valve is at least partially opened. A controller of controls one or more control valves to open only one of the intake valves of each cylinder in a condition of reduced engine operation, below a predetermined load and/or a predetermined speed of the engine, and to always open both intake valves in the remaining conditions of engine operation. The first intake valve is the only valve to be opened in the reduced engine operation condition.Type: GrantFiled: August 6, 2020Date of Patent: July 4, 2023Assignee: C.R.F.

Patent number: 11629654Abstract: An engine includes at least one cylinder, a first intake valve and a second intake valve associated with the cylinder, to control a flow of intake air from a first intake duct and a second intake duct, respectively. The two intake ducts communicate with a common intake manifold, so as to receive air at the same pressure. During the intake stage, in each cylinder operating cycle, initially an opening and closing movement of only the first intake valve is activated, while the second intake valve remains closed and, subsequently, an opening and closing movement of only said second intake valve is activated, while the first intake valve remains closed. In this way, the two air flows at the same pressure entering the cylinder give rise to a high turbulent kinetic energy, to the advantage of combustion efficiency and reduction of harmful exhaust emissions.Type: GrantFiled: February 15, 2022Date of Patent: April 18, 2023Assignee: C.R.F.

Patent number: 10947321Abstract: A method for producing Metal Organic Framework (MOF) having a framework that encapsulates a bio-molecule, the method comprising combining in a solution the bio-molecule and MOF precursors, wherein the bio-molecule promotes formation of the encapsulating framework. The method stems from a surprising effect that a bio-molecule can promote or trigger the formation of MOF when combined together in a solution with MOF precursors. That is, it has now been found that a bio-molecule can effectively act as a seed around which the framework forms, with the resulting framework encapsulating the bio-molecule.Type: GrantFiled: May 19, 2015Date of Patent: March 16, 2021Assignee: Commonwealth Scientific and Industrial Research OrganisationInventors: Kang Liang, Raffaele Ricco, Cara Maxwell Doherty, Paolo Falcaro

Patent number: 10746063Abstract: An actuating system of an engine valve comprises a movable member, for example, in the form of a master piston controlled by a cam of a camshaft. A slave piston is hydraulically controlled by the master piston by means of a volume of pressurized fluid, to open said engine valve against the action of a return spring. The system also comprises an auxiliary device for applying an additional force to the engine valve to keep the engine valve in a closed position. The auxiliary device is configured or controlled in such a way that the total force tending to keep the engine valve in its closed position varies during each rotation cycle of the cam. The total force is higher at least in one part of the rotation cycle of the cam wherein the engine valve must remain in its closed position, and is, instead, reduced at least in one part of the rotation cycle of the cam wherein the engine valve is not in its closed position.Type: GrantFiled: August 23, 2018Date of Patent: August 18, 2020Assignee: C.R.F.

Patent number: 10156163Abstract: A system for variable actuation of an engine valve of an internal-combustion engine includes a master piston and a slave piston, driven by the master piston. A control valve controls a communication of a volume of a pressurized fluid with a lower pressure environment, which is connected to a fluid accumulator, and an electronic control unit controls the electrically operated control valve. A device for dampening pressure oscillations is connected to the volume of pressurized fluid and includes an additional volume adapted for receiving fluid from the volume of pressurized fluid only when, following upon oscillations of the pressure in the volume of pressurized fluid, the pressure exceeds a maximum threshold value, which is higher than a mean pressure value that is set up in the volume of pressurized fluid when the master piston drives the slave piston in normal operating conditions.Type: GrantFiled: September 29, 2016Date of Patent: December 18, 2018Assignee: C.R.F.

Patent number: 10151221Abstract: A system for variable actuation of an engine valve of an engine includes a master piston driven by a cam of a camshaft. A slave piston is driven by the master piston by a volume of pressurized fluid. The slave piston causes the engine valve to open, against the action of a spring. A control valve controls a communication between pressurized fluid and an environment at lower pressure, with which a fluid accumulator is in communication. A control unit is programmed for controlling the control valve according to one or more different valve modes. When one of these valve modes is actuated, the control valve opens the communication in advance with respect to the end of the lift cycle of the cam, and not after closing of the engine valve to prevent or reduce a decrease in pressure in the volume of pressurized fluid after closing of the engine valve.Type: GrantFiled: December 1, 2016Date of Patent: December 11, 2018Assignee: C.R.F.

Patent number: 9970397Abstract: A fuel electro-injector for a fuel injection system for an internal combustion engine, having an atomizer equipped with a nozzle and a valve needle defining a discharge section that is annular and has a width that continuously increases as the opening stroke of the valve needle proceeds. The opening stroke is directed outwards and is caused, in a proportional manner, by the operation of an electric actuator. The electro-injector has a high-pressure environment with an annular passageway around the lateral outer surface of the valve needle to supply fuel to the discharge section, and a low-pressure environment, which communicates with a fuel outlet and is separated from the high-pressure environment by a dynamic seal between the valve needle and the nozzle.Type: GrantFiled: October 20, 2014Date of Patent: May 15, 2018Assignee: C.R.F.
