Abstract

The present invention relates to a starter arrangement for an internal combustion engine. The starter arrangement comprises a starter motor (1) having a pinion gear (2) at an output shaft. The pinion gear (2) is arranged in constant engagement with a corresponding crank gear of a crank wheel (3) located between an engine block (4) and a flywheel (11) of the engine. The crank wheel (3) is operatively connected to a crankshaft of the engine via a one-way clutch unit (6). The one-way clutch unit (6) is arranged at an engine block (4) side of a crankshaft oil seal (7) enabling lubrication and cooling thereof by an engine oil of the engine.

Description

technical field [0001] The invention according to the preamble of claim 1 relates to a starter arrangement for an internal combustion engine. Furthermore, the invention according to the preamble of claim 10 also relates to a method of reducing strain on a starter arrangement of an internal combustion engine. Background technique [0002] So-called start-stop devices or idle-stop devices are based on the concept of stopping the internal combustion engine of a vehicle during a standstill, such as when waiting for a traffic light to change from red to green. Such a device allows substantial savings in fuel consumption. Savings are at least 2-4% for mixed highway / country and city driving and as much as 10% for city driving. [0003] Some previous attempts to provide such devices have been based on belt drives or starters. Starter-based systems are low-cost and adjustable to fit all sizes and types of powertrains, but have two major drawbacks. On the one hand, such a system c...
