Patent number: 11946429Abstract: An engine includes a single cylinder, at least one sensor, a fuel injector, and a controller. The at least one sensor is configured to generate sensor data for an engine condition.

Patent number: 11047769Abstract: In one example, fleet devices are monitored. The fleet devices include engines. A controller, such as an engine controller or centralized controller, receives sensor data indicative of a load on the engine from one or more of the fleet devices. The controller analyzes the load from the sensor data to identify a management function. The controller generates a message including the management function.Type: GrantFiled: July 24, 2018Date of Patent: June 29, 2021Assignee: Kohler Co.Inventors: William Schnell, Martin Radue, Travis Andren, Todd Baumann, Mark Johansen

Patent number: 7476136Abstract: A two-stroke internal combustion engine has two cylinders each having an exhaust port. Two exhaust conduits are connected to the two exhaust ports. A passage is provided between the two conduits to fluidly communicate the two together. An actuator moves a valve to open or close the passage depending on the engine speed.Type: GrantFiled: February 16, 2006Date of Patent: January 13, 2009Assignee: BRP US Inc.Inventors: Martin Radue, Sebastian Strauss, Peter Lucier, David Silorey

Patent number: 7410347Abstract: A reciprocating pump includes a drive section and a pump section. The drive section has a reciprocating coil assembly to which alternating polarity control signals are applied during operation. A permanent magnet structure of the drive section creates a magnetic flux field which interacts with an electromagnetic field produced during application of the control signals to the coil. Depending upon the polarity of the control signals applied to the coil, the coil is driven in one of two directions of movement. A drive member transfers movement of the coil to a pump element which reciprocates with the coil to draw fluid into a pump chamber and expel the fluid during each pump cycle. The pump is particularly well suited to cyclic pumping applications, such as fuel injection systems for internal combustion engines.Type: GrantFiled: August 4, 2005Date of Patent: August 12, 2008Assignee: BRP US Inc.Inventor: Martin Radue

Patent number: 7164984Abstract: State-of-the-art fuel injectors have an inherent time delay that is determined by an elapsed time from the time an electrical signal is received by the fuel injector from an ECU to the time that fuel is actually initially injected into the cylinder. That time is currently an average time and therefore the fuel injectors must be manufactured with very precise tolerances. The present invention includes a method and apparatus that allows the use of production fuel injectors that are more economical to manufacture by allowing wider tolerances. The invention includes determining the actual time delay for each fuel injector. The fuel injectors are supplied with a computer program and a data file containing the time delay determined especially for that particular fuel injector.Type: GrantFiled: March 7, 2006Date of Patent: January 16, 2007Assignee: BRP US Inc.Inventor: Martin Radue

Publication number: 20050039722Abstract: A system and method for operating a two-stroke engine that includes at least one cylinder, a piston reciprocally disposed therein, and a scavenging port for egress of exhaust gasses therefrom. A charge purity detector is in operable association with the at least one cylinder to detect irregular combustion in the at least one cylinder. An ECU is connected to receive signals from the charge purity detector and programmed to adjust a charge parameter in a next cycle in response to detected irregular combustion.Type: ApplicationFiled: October 21, 2003Publication date: February 24, 2005Inventors: David Montgomery, Martin Radue, Scott Koerner
