-- Tools to speed up your Research & Development -- DSi offers innovative equipment and services for engine/lubricant development and testing. DSi is a world leader in the use of radiotracer techniques. Our customers are from the automotive, lubricant, and aeronautic industries. We intervene as R&D partners for the development of new products and for resolving rapidly any technical problems. Advantages of the radiotracing tools are to reduce testing durations and costs as they offer results in real-time and with a higher accuracy than conventional methods. Radiotracers bring solution for: -) Oil consumption measurement (with separate contribution from the engine block, the ventilation system and the turbocharger), -) Fuel dilution measurement, -) Oil aeration measurement, -) Wear measurement (TLA/RNT) to follow up to 4 parts simultaneously with a one nanometer accuracy, -) Lubricant additives labelling and tracking, poisoning of exhaust post-treatment systems (catalysts and DPF), -) Design and manufacturing of fluid (oil and water) conditioning units with or without the possibility to produce adjustable oil aeration rate.
