Implementation of Innovative Actions & Future Suggestion
Implementation of Innovative Actions & Future Suggestion I. How a small thin O Ring stalls Motorcycle One of the leading two wheeler manufacturer in India observed that the FKM component is changing in volume & other properties with each successive exposure to atmospheric Heat & Gasoline fumes. According to them with the first exposure certain volumetric expansion takes place ( X ) and then when the part is kept out (dried in atmosphere) it does not return to it’s original state. In the second exposure it starts swelling again from an already swollen state. If in stage 2 the swelling is Y, the total swelling shall be X + Y”. A swollen FKM ( or any Elastomer ) product will take very long period to dry but it can never come to its zero position , will be very close to zero. Question is after what period that stage will reach. These factors need to be kept in mind while designing the item. This causes fuel vapour leakage stalling of Engine. Swelling characteristic is
