Intermittent Dual-fluid Exhaust Burner (IDEB) has been developed to reduce emissions from methanol fueled vehicles during the warm-up period after a cold start. The IDEB does not need any special fuel injector or blower, and has been built mainly through software modification of an ECU. An FTP mode test while operating an IDEB confirmed that the catalyst temperature was rapidly increased to significantly reduce the emissions to meet a level of ULEV standards.
