The AVL Smart Sampler is a particulate matter (PM) partial flow sampling system that meets the most recent U.S. EPA emissions measurement criteria. The system allows heavy-duty diesel engine manufacturers a more compact and cost-effective solution for transient test cycle PM measurement. The AVL Smart Sampler complies to the EPA Code of Federal Regulations (CFR) 40 1065.140 by mixing and diluting a small sample of engine exhaust flow with air under controlled conditions with respect to dilution air temperature, minimum dilution ratio, filter temperature, and residence time. The flexible system features a warm-up time of 15 min, which saves time and energy, while the single-trolley-mount design of the main and filter cabinets quickly caters to test-cell changeovers.
