/ 161 CANISTER CONDITIONING UNIT AVL CANLOAD Current trends and future demands concerning alternative fuels and various drive concepts require adequate and flexible test systems. AVL CANLOAD systems constitute a state-of-the-art test system by providing specific test solutions for a wide range and supporting standard certification, individual R&D and durability testing. MEASUREMENT PRINCIPLE The AVL CANLOAD pneumatic unit is designed for all standard applications based on butane/nitrogen or fuel vapor handling. It provides all required functions including individual valve matrix control, canister interface and mass-flow regulation. The elimination of volumes between valves and canister combined with intelligent software functions, e.g. delay time evaluation and time-based purge routines etc., increases accuracy and repeatability. Specially designed mass-flow controllers provide free adjustable mass flow rates. APPLICATION AVL CANLOAD is part of the AVL Evaporative Emission System, which has specifically been designed and developed to perform automotive evaporative emission tests. In particular, it also covers the future requirements based on new driving concepts as well as new fuel mixtures. A special material selection and an adequate system design guarantees reliable test data. This includes standard audit and certification test cycles as well as specific customized R&D processes and durability testing. Operating together with the AVL VT/VV-SHED systems, it stands for a complete facility allowing the whole evaporative test procedure to be carried out, from canister-conditioning and refueling to final emission data evaluation. BENEFITS AT A GLANCE • Uniform and flexible system design for synthetic gas & fuel vapor testing • Flexibility, quality & reproducibility to accelerate canister R&D processes • User-friendly and simple operator interface, intelligent service functions • Self-sufficient test automation for reliable, productive operation • Real-life testing with transient load and purge cycles Canload device automation: improved graphical look & feel operation interface for manual operation, specific diagnostics and services
