Highway Engine ETV Sample Clauses

Highway Engine ETV. Testing of technology intended to control emissions from highway diesel engines will be conducted generally under the provisions of 40 CFR Part 86 Subpart N. The primary emissions measurements will be of NOx, PM, HCs, CO, and other FTP specified emissions. CO2 and other emissions and measurements described by this protocol are secondary measurements. Each ETV test will consist of the same number of tests on the baseline broken-in engine, the de-greened emission control technology, and the technology after aging. The number of tests will include a single cold- and hot-start highway transient FTP engine dynamometer test and may include additional hot-start tests in numbers determined using the test design procedure described above. The emissions reductions will be reported as the composite of the cold and mean of the hot starts, as required by the FTP, and as the mean and confidence interval on multiple hot-start tests. The smoke test is not required. The test parameters will be derived from the baseline engine mapping procedure. Emissions reductions will be computed relative to the baseline engine emissions using the same test cycle used during the baseline testing. As required by the FTP, tests that do not meet the FTP QA requirements must be repeated. The test/QA plan for a specific technology will specify the engines that will be tested and any other aspects of the test that are specific to the technology or the test laboratory.
