Title: Opel Rekord Series E
Content: had already passed the law that would effectively enforce the use of catalytic converters for cars sold there, though at this stage the industry was still being given time, in West Germany, to prepare for the new laws to come into force: Switzerland and Sweden had already introduced much more stringent standards than other European nations, and catalytic converters began making inroads in the mid-80s. It was still believed that carbureter fed engines were liable to pass unburnt fuel into the exhaust chamber, with potentially damaging results for the converter, so the manufacturer chose to combine the new anti-pollution device

Title: Catalytic converter
Content: wood stoves to control emissions. This is usually in response to government regulation, either through direct environmental regulation or through health and safety regulations. Catalytic converter prototypes were first designed in France at the end of the 19th century, when only a few thousand "oil cars" were on the roads; it was constituted of an inert material coated with platinum, iridium, and palladium, sealed into a double metallic cylinder. A few decades later, a catalytic converter was patented by Eugene Houdry, a French mechanical engineer and expert in catalytic oil refining, who moved to the United States in 1930. When

Title: Bharat Stage emission standards
Content: which is estimated to be the cause for 6.2 lakh early deaths in 2010, and the health cost of air pollution in India has been assessed at 3% of its GDP. The first emission norms were introduced in India in 1991 for petrol and 1992 for diesel vehicles. These were followed by making the Catalytic converter mandatory for petrol vehicles and the introduction of unleaded petrol in the market. On 29 April 1999 the Supreme Court of India ruled that all vehicles in India have to meet Euro I or India 2000 norms by 1 June 1999 and Euro II

Title: Technological and industrial history of 20th-century Canada
Content: in the late sixties. The catalytic converter was also introduced during these years. The first devices, designed to reduce air pollution from automobile exhaust, were installed in the 1975 model year for US cars manufactured in Canada. Because of environmental concerns and the fact that it was not compatible with these converters, the major gasoline companies in Canada began to eliminate the sale of leaded gasoline that same year. Although Armand Bombardier invented the snowmobile, the initial production model, the B-7 dating from 1937 was a large 7 passenger vehicle. It was not until 1959 with the development of the

Title: Catalytic converter
Content: Catalytic converter A catalytic converter is an exhaust emission control device that converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction (an oxidation and a reduction reaction). Catalytic converters are usually used with internal combustion engines fueled by either gasoline or diesel—including lean-burn engines as well as kerosene heaters and stoves. The first widespread introduction of catalytic converters was in the United States automobile market. To comply with the U.S. Environmental Protection Agency's stricter regulation of exhaust emissions, most gasoline-powered vehicles starting with the 1975 model year must

Question: Which country was the first to make catalytic converters compulsory?
Answer: Switzerland
