Abstract

Opening and closing times of a fuel injector are accurately determined in accordance with the energy content of an accelerometer trace. The energy content of an accelerometer trace is determined in accordance with a predetermined relation. A line is defined between known points prior to and after the opening or closing time. The normal distance between the line connecting known points and the accelerometer trace energy content is maximum at the inflection point, which corresponds to the opening or closing time. With this data, an ECU can be properly programmed to more accurately control an injector stroke, thereby improving engine performance.
