A fuel injection systems manufacturer had incorporated the use of two steel brackets to clamp the fuel rail to the top of the engine. The customer was looking at changing these brackets to plastic as a cost reduction. In order to prevent deformation of the plastic bracket during the tightening of the bolt, a Compression Limiter was required.
The customer originally investigated the use of a machined Compression Limiter, but the savings from changing the metal bracket to plastic would have been lost considering the high price of the machined Limiter. The customer approached SPIROL to help provide a lower cost solution for the Compression Limiter.
