Assessment of the Strength Reduction on the Forged Fuel Rails due to Corrosion Impact of the Ethanol Content in Gasoline Fuels
Forged fuel rails remain reliable despite corrosion from 100% ethanol fuel content.
This study investigated the strength reduction of forged fuel rails due to corrosion from ethanol in gasoline. The researchers found that the rails remained reliable after 240,000 km or 15 years of use, with a failure probability of less than 1 ppm.
Abstract
In this study, strength reduction of the bare rails under corrosive loads which is produced by the forging method is investigated and visualized. Aggressive media of Ethanol has a high corrosion impact on the steel components that reduces the fatigue strength of those parts. Reliability of the forged bare rails are checked after the strength reduction to prove the forged bare rail must be still reliable in the field usage during its service time which is equal to 240.000 km or 15 years. It is proven that failure probability of those parts which are affected by the 100% ethanol content of the fuel in the gasoline internal combustion engine is less than 1 ppm (parts per million).
