Starter pulley arrangement
11802532 · 2023-10-31 · ·

The present disclosure relates to a starter pulley arrangement for an internal combustion engine. The arrangement comprises a cord drum (1) configured to house a starting rope wound thereon, a driver (3) configured to interact with a flywheel (5) or other part connected to an engine crankshaft, and a torsion spring (7) connecting the cord drum (1) to the driver (3), such that the cord drum can resiliently urge the engine crankshaft via the driver. The torsion spring (7) is tensioned in a resting position where the driver does not influence the crankshaft. This provides an improved resistance against wear on the parts of the starter pulley arrangement.

INTEGRATED ENGINE MOUNT

Embodiments include a snowmobile comprising a frame and an engine, the engine including a crankcase mounted to the frame with a crankshaft axis of rotation positioned perpendicular to a longitudinal centerline of the frame. The crankcase includes a cast lower surface comprising a first structural wall extending substantially perpendicular to the longitudinal centerline and a second structural wall extending substantially perpendicular to the longitudinal centerline. The lower cast surface further includes a panel extending between the first structural wall and the second structural wall, the panel defining a curved surface and a mounting surface extending from the first structural wall and across at least a first portion of the panel. The snowmobile further comprises an engine mount connected to the frame comprising a housing and a damper. The housing is secured to the mounting surface with a first fastener that extends into the first structural wall to position the damper opposite the panel, and the engine mount is positioned below the engine.

Rope reel for recoil starter, and recoil

There is provided a rope reel provided in a recoil starter including: a rope holding groove; a flange portion disposed on both sides of the rope holding groove; a through hole provided in the flange portion and configured to allow an end of the rope wound around the rope holding groove to pass through; and an arch portion provided on a side surface of the rope reel and adjacent to the through hole. The arch portion is configured such that the rope is inserted therein, and the arch portion is capable of holding the inserted rope along the side surface of the rope reel. According to the above configuration, a front end portion of the rope is prevented from interfering with a rotation member at an engine side.

Method and system for starting an internal combustion engine

A method for starting an internal combustion engine (ICE) having a crankshaft and an electric turning machine (ETM) operatively connected to the crankshaft comprises energizing an absolute position sensor adapted for providing an indication of an angular position of a rotor of the ETM and applying a current to the ETM to generate a sufficient torque to rotate the crankshaft.
