(Sierra) conducted a study of on-road motor vehicle emissions data to determine the primarycauses of excessive exhaust emissions in the in-use motor vehicle fleet.* That topic is important from the perspective of how to craft motor vehicle control programs toeffectively reduce in-use emissions. The analyses performed in this effort attempted to quantify the emissions impacts of individual emission control system componentdefects, the prevalence of those defects in the in-use motor vehicle fleet, and the overall contribution of those defects to fleet-average emissions. In addition, the primarycauses of defective emission control system components were categorized according to whether the defect was the result of a mechanical component failure, electricalcomponent failure, poor maintenance, or tampering. Estimates of the magnitude of each of these failure modes on excessive emissions were then made. <\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Analysis of Causes of Failure in High Emitting Cars<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/api\/\"><b>API<\/b><\/a><\/td>\n<td>1996<\/td>\n<td>102<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":487719,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2642],"product_tag":[],"class_list":{"0":"post-487710","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-api","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/487710","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/487719"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=487710"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=487710"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=487710"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
