Abstract (en)
[origin: EP0735257A2] An exhaust pulsation control system for an internal combustion engine having at least one cylinder communicating with an intake passage via an intake port and with an exhaust passage via an exhaust port, comprises engine operating condition detecting means and exhaust gas temperature detecting means. Further, there is provided a memory storing target values of exhaust gas temperature related to predetermined engine operating conditions and a control means connected to said memory and adapted to control an air/fuel ratio of an air/fuel mixture to be supplied to said engine so as to approach said detected exhaust gas temperature to said target exhaust gas temperature corresponding to the engine operating conditions detected. <IMAGE>
