Summary:

Internal combustion engines are designed to meet the high power,low fuel consumption and also, low exhaust emissions. The enginerunning conditions is valid the concept that, the expectative isvery high because of the variety of operating conditions like coldstart, frequent start and stop, time high speed and load,traditional gasoline, mix of gasoline and alcohol and finally,alcohol fuel only.Considering such demand, this paper explains the relationshipbetween the reliability bathtub curve, specifically the"Infant Mortality" portion. The bathtub curve describesfailure rate as a function of time. The "InfantMortality" portion of the curve is the initial section forwhich the failure (death) rate decreases with time (age). Ingeneral, these problems are related to manufacturing aspects orpoor design definitions.With development of technology, hard failures, the ones thatcause dependability, are becoming rare. On the other hand, softfailures, the ones that cause poor customer perception, areincreasing with competition and customer high demand. This paperfocuses on a literature review of these two categories, approachingfirstly the mechanisms of failures and secondly, a shortdescription of the basic concepts. Also, a special emphasis isgiven to engine noises.Throughout this discipline to understand the failure mechanismand then, the basic concepts, it is expected to: 1) concentrate onperfect systems, not perfect components, 2) understand interactionfailure modes and finally 3) do not pack more functionality intoone button just because you can, the paper discusses therelationship with engine typical failure modes. In addition, betteradvanced quality plans and control plans can be performed
