Abstract
E.F.S. company introduces two complexity innovative instruments for laboratory and on line characterization of modern automotive injection system. The first is dedicated to the standard low pressure indirect gasoline injection systems. This new design provides perfect regulation of the gasoline pressure at the injector inlet while it's outlet may inject into a negatively pressurized volume, perfectly emulating the effective real functioning conditions. The second one concerns high-pressure injection systems. In addition to the well known shot flow measuring systems continuously improved by E.F.S. for 20 years the new design adds the very accurate measurement of the injection rate, both parameter being measured with an unprecedented accuracy by one compact instrument.
