Patent number: 10494968Abstract: An oil separator is designed for an internal combustion engine with a camshaft system, via which oil separator a medium containing oil-particle-enriched blow-by gases, is influenced to the effect that the oil particles and the blow-by gases are separated and supplied to an oil circuit or to an inlet system of the internal combustion engine. The oil particles are separated from the blow-by gases by rotation of the camshaft system. In order to optimize this oil separator, the camshaft system has at least one camshaft on which a centrifugal blade device acting as the oil separator is effective. The centrifugal blade device conveys the oil particles of the medium against housing walls which are adjacent relative to the camshaft and lead to the oil circuit, with the blow-by gases freed from oil particles being conducted into the inlet system by the pressure conditions prevailing in a crankcase of the internal combustion engine.Type: GrantFiled: July 6, 2017Date of Patent: December 3, 2019Assignee: Neanders Motors AGInventor: Claus Bruestle

Patent number: 10273863Abstract: A fan is suitable for an air-guiding system of an outboard motor including an internal combustion engine and a covering hood bounding an engine interior space. The engine drives the fan, which is connected to an upright shaft journal projecting beyond an upper side of a housing of the engine. The covering hood has air flow openings, and the fan influences the air flows in the covering hood interior space. A flywheel, fixedly attached to the upright shaft journal, carries a fan wheel of the fan. The fan wheel is set in place from above, and the flywheel carries the fan wheel for conjoint rotation. Airflows enter the interior space via an inlet opening and a first conducting device, and the airflows, under the action of the fan, act upon at least parts of surfaces of the internal combustion engine and the auxiliary units to cool the internal combustion engine.Type: GrantFiled: April 19, 2017Date of Patent: April 30, 2019Assignee: Neander Motors AGInventors: Claus Bruestle, Richard Davis

Patent number: 10220927Abstract: An outboard motor including an internal combustion engine for propelling a ship is equipped with an air-guiding system using a covering hood surrounding surfaces of the internal combustion engine and auxiliary units. The covering hood is provided with airflow inlet and outlet openings in its interior, and a fan driven by the internal combustion engine influences airflows in the covering hood. An air-guiding system includes channeling devices for partial air flows. First partial air flows are fed as intake air to an engine intake system, and second partial air flows act, with the aid of the fan, on surfaces of the internal combustion engine and the auxiliary units heated by operation of the internal combustion engine. The heated airflows are conveyed by the fan and a third channeling device as exhaust air via an outlet opening in the covering hood outside of the covering hood or into the atmosphere.Type: GrantFiled: April 19, 2017Date of Patent: March 5, 2019Assignee: Neander Motors AGInventor: Claus Bruestle

Patent number: 10047670Abstract: An internal combustion engine has at least one piston which performs stroke movements in a cylinder crankcase. Via two connecting rods, the piston interacts with two parallel crankshafts which rotate synchronously in opposite directions. The connecting rods have, on a side facing toward a piston crown of the piston, bearing eyelets which, via piston pins, are operatively connected to the first and second bearings provided at opposite first and second sides of the piston, which bearings and piston pins act as a device for compensating an asymmetry of the profile of the crankshafts. To optimize the internal combustion engine, the first and the second bearings have cylindrical bearing disks which, firstly, are rotatably mounted in piston bores and which, secondly, include disk bores for receiving first and second pin sections of the piston pins.Type: GrantFiled: January 6, 2016Date of Patent: August 14, 2018Assignee: Neander Motors AGInventor: Claus Bruestle

Patent number: 7954314Abstract: An engine is provided with a cavity so that a catalyst member can be contained within the engine when an engine head portion is attached to an engine block portion. This attachment of the engine head portion and engine block portion, which forms the engine structure, captivates the catalyst member within the cavity without the need for additional brackets and housing structures. The cavity is preferably located above or at the upper regions of first and second exhaust conduits which direct exhaust upwardly from the engine head portion toward the cavity and downwardly from the cavity within the engine block portion. The first and second exhaust conduits are preferably formed as integral structures within the engine head portion and engine block portion.Type: GrantFiled: September 6, 2005Date of Patent: June 7, 2011Assignee: Brunswick CorporationInventors: Claus Bruestle, Richard A.

Patent number: 7383799Abstract: A system is provided for monitoring changes in the operation of a valve system of an engine. An accelerometer provides vibration-related signals that are obtained by a microprocessor or similarly configured device and compared to a reference or baseline magnitude. The obtaining step can comprise the steps of measuring, filtering, rectifying, and integrating individual data points obtained during specific windows of time determined as a function of the rotational position of the crankshaft of the engine. These windows in time are preferably selected as a function of the position of exhaust or intake valves as they move in response to rotation of cams of the valve system.Type: GrantFiled: October 13, 2005Date of Patent: June 10, 2008Assignee: Brunswick CorporationInventors: Steve Wynveen, Claus Bruestle, Timothy S.

Patent number: 7278367Abstract: A steering wheel provides a control device that is easily maneuverable, by one hand, by an operator who is gripping the rim of the steering wheel. Release of the rim is not necessary to affect a change in the control parameter of an engine or other element of a marine vessel through use of the control device. The control device is rotatable about an axis of rotation which is generally parallel to a line which is tangent to a centerline of the rim of the steering wheel.Type: GrantFiled: July 5, 2005Date of Patent: October 9, 2007Assignee: Brunswick CorporationInventors: Steven J.

Patent number: 7216638Abstract: A method for operating a marine engine uses four valves to control the flow of secondary air that is inducted into each of the cylinders of an engine. An oxygen sensor is disposed in an exhaust passage downstream from the cylinders and upstream from a catalytic converter. A carburetor is calibrated to provide a richer than stoichiometric air/fuel ratio so that inducted secondary air through the valves associated with each cylinder can result in a stoichiometric ratio of air flowing into each cylinder. The cylinders are each provided with their own valve in order to allow the air/fuel ratios to be equalized for each cylinder regardless of the configuration and geometry of the intake manifold and its associated conduits.Type: GrantFiled: July 6, 2006Date of Patent: May 15, 2007Assignee: Brunswick CorporationInventors: Reinhard Burk, Brian R. White, Claus Bruestle
