The function of the one-way clutch that is fitted to a pre-engaged starter motor is:

• to prevent the engine driving the starter motor if the starter switch is not released

• to prevent damage to the flywheel ring gear during the engagement of the pinion

In an engine lubrication system the relief valve:

• controls the viscosity index of the engine oil

• limits the minimum oil pressure to the bearings

• limits the maximum oil pressure to the bearings
