Cadillac Secondary Air Injection Pump injects fresh air to reduce cold-start emissions in a short time. Cadillac started in 1902 and soon gained a reputation for clean design and daring engineering, and was among the first marques. Customers love the accommodating cabins, upscale driving interfaces, and smooth powertrains which seem to make the long way look short. The advanced technologies such as full-width touch screens and smart glass roof demonstrate that Cadillac continues to drive comfort in the future. Even its electric flagship which is hand-built shows its dedication to the art, history, and constant innovation without affecting performance. Owners treasure the simple combination of luxury and contemporary comfort that allows them to have a real opportunity to enjoy the open everyday road instead of struggling with it. The Cadillac Secondary Air Injection Pump is located in the air system as it injects contaminated oxygen-rich air into the exhaust stream immediately after ignition. It reduces the production of hydrocarbons and carbon monoxide by burning off uncombusted fuel prior to gaseous entry into the catalytic converter and highly notably during warm-up. Electric or belt drive maintains the operation of the Secondary Air Injection Pump to provide a constant supply of air at an engine temperature that is reliable. Protective diverter and check valves help protect the Secondary Air Injection Pump against backflow of hot water to ensure that the unit lives and does not create ugly backfires.
