/ 171 GRAVIMETRIC PARTICULATE MATTER MEASUREMENT WITH PARTIAL FLOW DILUTION AVL Smart Sampler The AVL Smart Sampler is a part ial flow dilution system used in gravimetric part iculate matter sampling from internal combustion engines in accordance with ISO 16183, 40-CFR 1065 , 1066 and al l other relevant global regulations. MEASUREMENT PRINCIPLE A partial flow dilution system such as the AVL Smart Sampler mixes and dilutes a small sample of the exhaust flow with air under controlled conditions. This allows particulates to form in a repeatable manner simulating reactions in the atmosphere. The system samples the diluted exhaust over a filter medium where the particulates are captured and can subsequently be weighed. The flexible design also allows the AVL Smart Sampler to be used as a diluter for particle counting according to ECE regulation No 49 and Global Technical Regulation No 4. For particle counting, the system operates as it does for gravimetric measurement with a proportional sample of the diluted exhaust diverted to an optional particle counting device. A new field is the certification of passenger cars on chassis dynamometers according to US 40-CFR part 1066. APPLICATION The Smart Sampler can be used instead of a CVS for Euro III to VI certification, and, with the addition of the “add-on sampling” option, it also provides other testing devices like particle counters with diluted exhaust samples. The option of high pressure testing allows the Smart Sampler to be used at pressures as high as 1,000 millibar (gauge), and this makes it the perfect tool for efficiency evaluations and the optimization of DPF systems. The Smart Sampler can also be used for analyzing the influence of different fuels on PM emissions. The same Smart Sampler is suitable for sampling everything from small portable engines to the largest engines and can easily be moved between test cells for maximum flexibility. BENEFITS AT A GLANCE • Fulfills all relevant regulations • Fast warm up time: Smart Sampler is ready for operation in 15 minutes from a cold start. • With the optional add-on sampling, the Smart Sampler acts as a diluter for particle counting applications. • Modularity of components allows for simple structuring of options; future upgrades are simple and can be done at the customer’s site. • Rapid set up time for quick test cell changeovers • Automatic Filter Changer for up to 20 PM filters. Above: Due to the small and modular design of the Smart Sampler, it can be placed even in smallest test cells Left: The Smart Sampler‘s software is intuitive and easy to use
