The vehicle manufacturers have developed lean-burn engine to improve fuel economy. Unfortunately, these engines often emit large amounts of nitrogen oxides that can combine with hydrocarbons to form photochemical smog and acid rain which are harmful to both human health and the environment.
LYDS engineers have responded to this problem by developing control devices that reduce the exhaust emission of NOx, CO, and HC. These control devices include exhaust gas re-circulation valves, EGR sensors, thermal vacuum valves, idle speed valves, throttle position sensors, and oxygen sensors. Our engineers are continually improving the design and performance of these valves and sensors to meet the requirements of our customers. LYDS products help the vehicle manufacturers develop fuel efficient engines without sacrificing environmental quality.
