- W625132160 abstract "This article outlines past, present and forthcoming measures for reducing emissions from motor vehicles in the USA and in California. Early measures to satisfy tailpipe emissions regulations reduce driveability and/or fuel economy, but this trend was reversed when an oxidising catalyst was introduced in 1975. In 1985, a stricter NOx standard brought the reducing catalyst and closed-loop electronic control, and phased out the traditional carburettor. Federal Tier I standards, beginning to come in during 1994, will further reduce emissions of non-methane hydrocarbons and NOx. Various ways are being investigated, to adapt the currently dominant type of passenger engine to these stricter standards; they include more precise control of air-fuel ratio and individual cylinder control. The US Federal Government will require the use of alternative fuels in metropolitan areas with the worst ozone problems. The most likely alternatives at present are reformulated petrol, natural gas and M85. California has defined a new series of low-emission vehicles, with standards stricter than the Federal Tier I standards. They will regulate non-methane organic gases rather than non-methane hydrocarbons. For the covering abstract see IRRD 867146." @default.
