An Automatic Test Equipment for Automotive Engine Ignitors

Using Tcl/Tk for an Automatic Test Engine

Test Automation Programming Interface with Object Controlled Authentication, TAPIoca, is a Tcl/Tk based automatic test environment. It grew out of the need to construct automatic tests at the system level that could send commands to a System Under Test (SUT), get responses from the SUT, and control signal generation equipment connected to the same SUT. Tcl/Tk was chosen as the basis for this au...

A Micro-Kernel Test Engine for Automatic Test System

In traditional automatic test solutions, a test engine usually encompasses all functions in its kernel, including compiling test program, generating test event chain, scheduling test process and executing test events. This makes the engine tightly coupled with test language and the system under test, so that it is difficult to maintain, optimize and extend the test engine. In order to solve the...

Vibration control of an automotive engine using active mounts

In this research, vibration control of national engine (EF7) using active mounts is studied for two different mounting layouts. The first layout is based on the current engine mounting of national engine (system of three passive mounts), but the hydraulic mount is substituted by an active mount. The other mounting layout contains 4 mounts, 2 of which are active ones and the others are passive m...

Evaluation of Test Quantities for Leakage Diagnosis in the Air Path of an Automotive Engine

Two different methods for diagnosing leakage in the air-path of an automotive engine are investigated. The first is based on a comparison between measured and estimated air flows. The second is based on an estimation of the leakage area. The two methods are compared by using a framework of hypothesis testing and especially the power function. The investigation is made first in theory and then a...
