Pooka Yoke Research Paper

Abstract:
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).
It does the job of filtering the fuel. Filters help to protect the most expensive parts of the engine by filtering out foreign particles that can damage a fuel injector. A damaged fuel filter can result in erratic performance, poor gas mileage and in some cases, complete engine shutdown. Even the smallest particles can cause considerable wear and tear to an engine. Protecting the fuel system and the engine from harmful particles, helps to prolong the life of your vehicle. Ensure dependable and trouble-free performance with a Fuel Filter. Thus we can say that filter is significant in healthy working of the injector and ultimately the vehicle.
This project is designed to detect the presence of filter rod within an injector using poka yoke methodology. Where poka yoke is a mistake proofing technique which helps people and processes work right the first time. The use of simple poka yoke ideas and methods in product and process design can eliminate both human and mechanical errors. Poka yoke ensures that proper conditions exist before actually executing a process step, preventing defects from occurring in the first place. Poka yoke perform a detective function, eliminating defects in the process as early as
