- Description
- In accordance with FAR Part 12 procedures, the EPA?s National Vehicle and Fuel Emission Laboratory (Ann Arbor, Michigan) plans to procure a modern exhaust emissions sampling system. The new sampling system will need to be installed in EPA?s heavy duty test cell 2. The emissions sampling system will provide the functions of the constant volume sampler (CVS), as those functions are defined in 40 CFR 86.1310-2007. However, the emissions sampler will have certain enhanced features. These features include a low loss dilution tunnel and sample handling system, the direct mass flow measurement of dilution air, constant mass flow operation and proportional ambient sampling. Flow measurement of the dilution air and dilute exhaust will be accomplished by ultrasonic flow meters. The scope of activity in this procurement is to fabricate, deliver, and install the exhaust emissions sampling system. This capability is needed in order to test low-emission heavy-duty engines equipped with advanced exhaust emission control systems. This capability will be used to support the technology review for the 2007 Heavy-Duty On-highway Emissions Standards, and will also be needed in order to accurately measure gaseous emissions from heavy-duty diesel engines certified to the 2007 Heavy-duty On-highway Emissions Standards. Heavy Duty test cell 2 is an engine dynamometer test cell. The test cell is designed to run transient and steady state exhaust emission tests on large engines, primarily diesel. These engines are typically used in on-highway truck applications, or non-road applications such as agricultural equipment. The engines tested in this test cell typically have rated power values from 100 to 600 HP. The testing consists of steady mode operation as well as transient testing simulating a city or highway driving experience. During testing, the exhaust emissions are sampled and measured along with many other parameters including actual engine power output. Finally, emission rates are calculated to yield brake specific results or mass of emissions per unit of engine work. Testing is conducted according to U.S. Federal Standards (40 CFR Part 86, Subpart N) and standards from other international governing bodies. The contractor shall deliver to the EPA an installed, commissioned, and acceptance tested exhaust emissions sampling system. The contractor is responsible for the removal of all old equipment, the installation of the new system, commissioning, and training of EPA personnel. In addition, the contractor shall provide complete, detailed schematics of their systems and how the integration of all the systems and physical layout shall be facilitated. The final design shall provide two sets of documentation, including wire lists, color coding, electrical schematics, piping/tubing diagrams, operating manuals and computer system documentation. Operating/repair manuals for all equipment and instrumentation shall be supplied under this contract. Recommended preventative maintenance, spare parts, and warranty provisions shall be provided in writing. The EPA shall provide the necessary utilities, within 50 feet of the site. The contractor, at the completion of the installation and commissioning of the exhaust emissions sampling system shall conduct acceptance testing. The statement of work is written to allow flexibility of potential solutions to meet the requirements. While there is a certain minimum complexity required to meet the requirements, the preferred solutions ahighway truck applications, or non-road applications such as agricultural equipment.

The statement of work is written to allow flexibility of potential solutions to meet the requirements. While there is a certain minimum complexity required to meet the requirements, the preferred solutions are those which are not overly complex. The range of possible applications of the emissions sampler can only be estimated at the present time. The ultimate utility of such a system will depend on how easily it can be adapted to future needs. The design philosophy therefore, should be built on the idea that every part of the system should allow for future changes, re-configuration or upgrades. An overly complex solution or proprietary systems limit the future flexibility. The goal of this project is for EPA to procure a simple, yet technologically advanced Exhaust Emissions Sampling System (CVS). System Design Goals: - Size emissions sampling system to test diesel engines up to 600 HP - System for a dilute exhaust flow range of 3,000 to 10,000 SCFM - Sample handling for low loss of particulates and gaseous emissions - Measure dilution air directly - Operate system at constant mass flow - Provide proportional sampling of dilution air Emissions Sampler Application: The emissions sampler specification in the statement of work is an incremental improvement of constant volume sampler (CVS) designs that have been used over the past two decades. The CVS method is a common and recognized method for determining engine mass emissions and it draws its strengths from the simplicity of its operations. The functional, simplified description of a CVS is to collect a small sample of dilute exhaust gas and to measure the total volume of that dilute exhaust gas. This information combined with gas concentration, measured by a separate instrument, is all that is necessary to determine mass emissions. Fundamentally, this process will remain unchanged in this system. The system described in the Statement of Work uses some incremental improvements to correct some problems encountered when testing large engines (up to 600 Hp) at low emissions levels. These improvements include better sample handling, and revised flow control and flow measurement methods. Thre those which are not overly complex.

These improvements include better sample handling, and revised flow control and flow measurement methods. The system described in the Statement of Work is presented both from a component function level and from a system function level. All of the components that have been specified in the Statement of Work are commercially available. If an offeror is aware of a better product or approach, they are encouraged to suggest these in their proposal. Ultimately, the contractor shall deliver to the EPA an installed, commissioned, and acceptance tested exhaust emissions sampling system that meets the design and system goals. A Maximum two (2) week on-site commissioning period needs to be allowed for in the contractors proposed schedule. EPA will work jointly with the contractor during the commissioning period to ensure the date is met. Safety Features: Certain conditions in the test cell operation at large may require that the emissions sampler be shut down quickly. Controls shall be designed to allow a fast shutdown of the blowers from a dedicated digital input signal supplied from an external source. Major Systems and Physical Layout: The emissions sampler is comprised of three major systems. A Primary Dilution Air Processing B Primary Dilution Tunnel C Dilute Exhaust Processing Each system is described in the Statement of Work in detail. The layout of these major systems is similar to designs used by EPA in the past. The layout of the system will be done on two levels. This will include the test cell and a structural mezzanine above the test cell. This saves a great deal of floor space on the main floor. The primary dilution tunnel will be placed in the test cell for close proximity to the test engine. The end of the dilution tunnel will pass through a wall into an equipment room where the sample zone will be located. The mezzanine level will house the dilution air processing and dilute exhaust processing portions of the system. The equipment must be designed to fit into the space that is available. The room sizes are as follows: Test ce system described in the Statement of Work is presented both from a component function level and from a system function level.

There is an additional 4? of height in the building steel area, which may be used. An overall system drawing is included in the Statement of Work to show the spaces relative to each other and one layout design possibility of the emissions sampler.
