Analysis And Countermeasures Research Of A Certain Type Of Engine Quality Tracking

With the developing of society, automobile has not just become one of the most importanttransportation, it also has the largest number, the most popularity, the largest scope of activitiesand the largest traffic volume. After decades development, automobile has become theindispensible transportation in people’s life. Engine, as the heart of a car; provides power forthe car; Which is related to a car’s power performance, economical efficiency andenvironmental protection. All of these are show how important an engine to the car. An Enginequality decides a car’s quality, then decides the car’s market competitiveness and profit.If an engine burns oil, it will severely damage the engine and infect the engine quality.It’s not just waste of oil, but also lower the engine power. As an engine company, it has toprevent, to avoid and to control such things. This essay is trying to find a way to research howto solve the burning oil problem on the market, through theoretical reason of oil burning andfault analysis example from an engine company and the experience of how they solve thisproblem; Then to reach the goal of improving engine quality.First of all, find out and sum up the theoretical reason of burning oil;Second, gathering and doing statistical analysis the quality feedback from the customerservice markets:①Doing research on the occurrence time of the hitch; the production datesof the fault machine; actual service life; the regional distribution of the hitch occurrences;Summarize whether there are some rules of the hitch occurrences.②Study on each spareparts supplier’s quality, and summarize whether the hitch occurrences are related to somespare parts quality problems.③Conduct a study on Dimensional coordination， assemblymethod and assembly process, etc. Summarize whether the assembly quality is affect the hitchoccurrence.Then, based on the theoretical reason and the statistical analysis above, to infer thepossible reasons;At last, along with disassemble; detect relevant dimensions, compare tear down results,contrast relevant data and repeated experimental verification; Screening out possible causes,verify the validity of the infer, then get to the root of the problem. And after that, takemeasures to rectify and reform, and confirm effectiveness with experiments. By using this research technique, the cause analysis and reform has finally complete. Thisresearch solved the burning oil problem for market, because of which, the engine quality,competitiveness and sales volume are all raised, meanwhile, customer complaints andcompany financial loss has reduced.
