Filter Rod Detection By Using Poka Yoke

Diesel fuel is a complex mixture of hydrocarbons and it is well known that in extreme cold operating conditions some of these (paraffin) form wax crystals that will block the fuel filter and prevent engine operation. Also, due to dust and foreign particles engine may get damage. Filtration is mainly done with filter rod. If this rod is missing, then filter will not work properly and hence will result into the dysfunction. Poka-yoke is a concept in total quality management which is related to restricting errors at source itself. It deals with "fail-saving" or "mistake-proofing". A poka-yoke is any idea generation or mechanism development in a total productive management process that helps operator to avoid (yokeru) mistakes (poka). The concept was generated, and developed by Shigeo Shingo for the Toyota Production System. This paper is based on project for detection of the missing filter rod by using Poka yoke method.
