AbstractThis study aims to: 1. create a removable valve valve grinder and a car to escape a semi-automatic zero indent. 2. unplug the machine and grinding performance in order to find the valve valve car escape semi-automatic zero indent. 3. to compare the duration of valve and valve assembly valve car indentation between the Centre and crack the escape valve assembly valve car escaped with a semi automatic zero indent using special tools. (C-Camp) 4. to study the user satisfaction in enterprises that have a connection and unplug the valve assembly valve car escape semi-automatic zero indent, using the tools that are in the research and recording the results of the experiment in research and analysis of data measured from the.Most assessments, satisfied, very satisfied, 5 4. Satisfied moderately satisfied, meaning that at least 3 2 means that 1 the least satisfied, and collect results. 5. to study a broad range of experts, that has a connection, unplug the valve assembly and valve-automotive escape tool Center indent in the research, recording and digital recording is the result of experiments to analyze the suggestions, using the average value/save hundreds. The research found that removing the valve can be removed from the composed and assembled within 20 minutes and meet the assumption set.
