/ 173 GRAVIMETRIC PARTICULATE MATTER MEASUREMENT WITH PARTIAL FLOW DILUTION AVL Smart Sampler The AVL Smart Sampler is a part ial ow dilution system used in gravimetric part iculate matter sampling from internal comustion engines in accordance with ISO 16183, 40-CFR 1065 , 1066 and al l other relevant global regulations. MEASUREMENT PRINCIPLE A partial ow dilution system such as the AVL Smart Sampler mies and dilutes a small sample of the ehaust ow with air under controlled conditions. This allows particulates to form in a repeatale manner simulating reactions in the atmosphere. The system samples the diluted ehaust over a fi lter medium where the particulates are captured and can suseuently e weighed. The eile design also allows the AVL Smart Sampler to e used as a diluter for particle counting according to ECE regulation No 49 and loal 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 fi eld is the certifi cation of passenger cars on chassis dynamometers according to US 40-CFR part 1066. APPLICATION The Smart Sampler can e used instead of a CVS for Euro III to VI certifi cation, 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 milliar gauge, and this makes it the perfect tool for effi ciency evaluations and the optimization of PF systems. The Smart Sampler can also e used for analyzing the in uence of different fuels on PM emissions. The same Smart Sampler is suitale for sampling everything from small portale engines to the largest engines and can easily e moved etween test cells for maimum eiility. BENEFITS AT A GLANCE Fulfi lls 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 fi lters. 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
