ABSTRACT:
An engine having a turbo-supercharger comprised of a blower in the intake passage and an exhaust gas turbine in the exhaust passage. A charging pressure limiting device includes a pressure relief passage in the intake system or a turbine bypass passage in the exhaust system which is provided with a control valve. A control circuit is provided for limiting the peak charging pressure. The control circuit includes a limit signal generating circuit for providing a limit signal which decreases in response to an increase in the engine speed under a high speed range, a comparator for comparing the limit signal with the actual charging pressure signal and producing a control signal when the charging pressure signal reaches or exceeds the limit signal so that the charging pressure does not exceed the limit value which decreases in response to an increase in the engine speed under a high speed range.
