Advanced Diesel Power Testing Techniques 700666

This two-part paper covers advanced diesel power testing techniques for diesel power vehicles. The first part is concerned with an automatic diagnostic system capable of diagnosing malfunctions in diesel powered vehicles which has recently been developed. Diagnosis of fuel system, charging system, starting system, and cooling system can be accomplished by a relatively unskilled operator. The diagnostic system implements new design techniques, which greatly reduce the possibility of damage to both test equipment and vehicle under test, regardless of errors in hookup or use.The second part discusses silicon strain gage technology which has been found ideal for automotive analysis. Transducers have been developed and tested for a wide range of installations including diesel fuel injection pumps. Static through very high frequency data is illustrated over an operational life of greater than 100 million cycles.
