Emission Controls

Few people can appreciate the role that emission controls have played and continue to play in our health and everyday modern world. Since their first introduction on gasoline fueled U.S. passenger cars in 1975, catalytic converter technology has rapidly developed to address all fuels and engine types in both highway and off-road engine applications. In addition to catalyst, washcoat and substrate technologies, the field of emission controls also includes a variety of sensors, computer software, electronic engine controls and evaporative emission controls that are integrated as systems to ensure optimal engine performance and conditions necessary to ensure overall emissions are reduced by typically >99% while engine fuel economy, power and durability have been significantly improved.
