Engine Mechanical Testing: In-Cylinder Pressure Transducers
Learn to diagnose internal engine mechanical problems with minimal disassembly using a pressure transducer. This program will show how to interpret cranking and running compression patterns captured by an in-cylinder pressure transducer.
John Thornton will demonstrate step by step pattern analysis, show how to set-up and use overlays to clarify your captures, and provide examples of good and bad test results. Also included are useful and up-to-date specifications for modern engines. The techniques shown help quickly analyze valve sealing issues, valve opening and closing events, crankshaft reluctor problems, tight valves, incorrect cam timing, exhaust path restriction, correct or retarded ignition timing and more.
Learn methods to increase the accuracy of your analysis and reduce time spent disassembling by applying in-cylinder pressure testing to your diagnostic routine.
