- Description
- The U.S. EPA intends to negotiate on a sole source basis, under the authority of FAR Part 6.302-1, with AVL - North America, Inc. to provide an engineering study and possible upgrade to the Constant Volume Sampler (CVS) in heavy duty test cell 2 to meet the requirements of 40 CFR Part 1065 for the National Vehicle and Fuel Emissions Laboratory (NVFEL), 2565 Plymouth Road, Ann Arbor, Michigan 48105. The CVS in heavy duty test cell 2 was originally designed and built by AVL - North America and installed at EPA in 2004. The heavy duty engine emission sampling system was developed by AVL to measure 2007 level post-DPF particulate matter, including polyaromatic hydrocarbons. The CVS tunnel was designed by AVL with unique features including radial in-flow. These capabilities have been used extensively over the past 10 years. However, a change in CVS flow is necessary to conform with 40 CFR part 1065 particulate sampling requirements. The lower flow may drive several changes that are intended to improve the accuracy and repeatability of low-level emissions measurement. EPA requires AVL - North America, Inc. to conduct an engineering study and possible upgrades to the CVS equipment. The engineering study will include the following topics: How to Lower the CVS Flow Rate Range to 1500 - 4300 SCFM; How to Prevent Aqueous Condensation; and Perform Software Modeling Analysis of Dilution Tunnel Mixing. The specific questions EPA plans to have answered before proceeding with upgrades include, but is not limited to: -How should the main and dilution air flow meters be revised in order to perform properly within the new flow range (1500 to 4300 SCFM)? The intent is to retain the flow meter measurement technology and the overall flow meter performance to at least equivalent to the current system. -How should the design of the tunnel mixing elements be revised to optimize turbulent flow mixing for uniform concentration sampling at the sample zone? -How should the CVS blowers be revised to perform properly within the new flow measurement range (1500 to 4300 SCFM)? The intent is to retain the flow rate and pressure control transient performance of all the blowers to at least equivalent to the current system. -How should the pulsation dampers be revised to perform properly within the new flow measurement range (1500 to 4300 SCFM)? The intent is to retain the pulse dampening control to at least equivalent to the current system. -Determine if it is possible to operate the CVS at a flow rate below 1500 SCFM, and still achieve the flow measurement and mixing goals. -Can the dilution tunnel wall flow be used to prevent aqueous condensation? -Can the stream of air being introduced across the tunnel wall adequately prevent aqueous condensation onto the tunnel wall? -What air velocity is necessary to overcome the forcing function of condensation? -Conduct a CFD software analysis of the dilution tunnel to study solutions for optimum mixing performance at the sample zone. -Determine viable mixing solutions for the new flow range (1500 to 4300 SCFM). -Develop an analysis plan to include an agreed upon set of conditions to analyze and bracket common operating ranges of engines, fuels, and flow rates. - Develop concentration and temperature distributions at the sample zone for the various conditions and mixing solutions. Once the engineering study is complete, EPA will determine if upgrades to the heavy duty test cell 2 CVS are viable and cost effective. Final plans for any upgrades will be determined based on the results of the engineering study. However, at this time, EPA anticipates it will have to upgrade the following in heavy duty test cell 2: -1065 Bag Sampling System - including Heated Bag Sampling -Lower the CVS Flow Rate -Revise the Tunnel Wall Flow to Prevent Aqueous Condensation -Calibrate the CVS -Update CVS Automation System to provide 1065 Functionality -Dilution Air Temperature and Relative Humidity Measurement However, these anticipated upgrades may need to be re-visited, if the engineering study uncovers unexpected results. EPA believes AVL - North America, Inc. is uniquely qualified for this effort due to their extensive expertise in the design and operation of its CVS System in Heavy Duty Test Cell 2. THIS NOTICE OF INTENT IS NOT A REQUEST FOR COMPETITIVE QUOTATIONS. However, any firm believing itself capable of providing the required engineering study and potential upgrades may submit appropriate documentation with 15 calendar days of electronic posting of this notice. A determination not to compete the proposed requirement based upon responses received will normally be considered solely within the discretion of the Government. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement or to proceed on a sole source basis. Documentation should be submitted in writing to Gerold Young II via e-mail to young.gerold@epa.gov. Telephone requests will not be honored.
