Claim Text:
1. An air injection system for a vehicle comprising: an engine having a fluid input end and a fluid output end capable of outputting an exhaust fluid, the engine being configured to provide an output torque; an air intake device configured to output an airflow; a rotatable mechanical connection coupled with the engine and having at least one of a belt or a gear; a supercharger including a compressor mechanically coupled with the rotatable mechanical connection for receiving the output torque of the engine, the compressor having a fluid input end for receiving the airflow outputted by the air intake device and a fluid output end for outputting compressed air; a first fluid path having a fluid input end coupled with the fluid output end of the compressor and a fluid output end coupled with the fluid input end of the engine; a second fluid path coupled with the fluid output end of the engine for transferring the exhaust fluid outputted by the engine; a catalyst coupled with the second fluid path and configured to receive the exhaust fluid from the second fluid path; a supplementary fluid path coupled with the first fluid path and the second fluid path, at least a portion of the supplementary fluid path being positioned adjacent to the engine and configured to receive heat generated from the engine for warming up the catalyst; a valve for controlling a fluid flow of the supplementary fluid path, the valve having a first configuration for allowing transmittal of at least some of the compressed air outputted by the compressor to the catalyst via the supplementary fluid path for warming up the catalyst using at least some of the compressed air outputted by the compressor to the catalyst via the supplementary fluid path and a second configuration for preventing transmittal of the compressed air outputted by the compressor to the catalyst via the supplementary fluid path; a first sensor positioned at a location downstream from the compressor for detecting a flow rate of at least some of the compressed air outputted by the compressor to the catalyst via the supplementary fluid path; a second sensor configured to detect a temperature value of the catalyst; and a controller coupled with the first sensor, the second sensor, and the valve and configured to control the valve to be in the first configuration or the second configuration based on the detected flow rate of the least some of the compressed air outputted by the compressor to the catalyst via the supplementary fluid path and the detected temperature value.
