Abstract: A determination is made whether or not the condition that the amount V of condensed water remaining in an intake passage has exceeded a predetermined upper limit has been met, based on an input parameter associated with the amount V. If, during an engine operation in an unsupercharged mode, a determination is made that the condition has been met, a condensed water discharging operation of a supercharger is performed such that the condensed water remaining is discharged to a cylinder of the engine through operation of the supercharger.

Abstract: An intake passage of an engine includes a throttle valve, a supercharger, and a bypass passage connecting an upstream side with a downstream side of the supercharger and opening when the supercharger is not acting. When the supercharger is not acting, the intake passage generates forward flows in which intake air flows from the throttle valve toward the supercharger and bypass-directed flows in which the intake air is reversed due to blockage of forward movement by the supercharger and flows from the supercharger side toward a connection port, of the bypass passage, opening in the intake passage. An evaporated fuel introduction opening leading evaporated fuel produced in a fuel tank to the intake passage opens in a wall surface, on which the bypass-directed flow is generated, in the intake passage.

Abstract: An exhaust gas recirculation (EGR) passage is connected with an intake passage (a bypass passage bypassing a supercharger) of an engine. The EGR passage includes, in a position close to a connection port to the intake passage, an expanding portion in which a passage cross-sectional area expands and which lowers a flow speed of EGR gas so as to reduce an uneven flow, in the connection port, of the EGR gas flowing into the intake passage.

Abstract: Disclosed is an engine which comprises: an engine body comprising a cylinder head and a cylinder block; an inlet duct attached to the engine body; and a fuel system component disposed between the engine body and the inlet duct, wherein the inlet duct is disposed on a vehicle forward side of the engine body when mounted to a vehicle, and wherein the inlet duct has: a fuel system component-corresponding portion located in a zone overlapping the fuel system component when viewed from the vehicle forward side, and a region located adjacent to the fuel system component-corresponding portion and having a lower rigidity than the fuel system component-corresponding portion.
