Internship Life 9

This is the last week for me to work and i felt time running faster than expected. Recently the new things i had learned is how to test Fuel Injection using injection tester. In the beginning, we need to pump the tester using Diesel up to at least 40MPA, after that we release it, Diesel will spray through the injector head that having 7 holes. Since this week we are doing Engine overhaul, we have to make sure all the component is work in the good condition iincluding the injector. The engine problem for this time is piston head crack. The reason causes might be the material problem or over working time.
