An internal combustion engine includes an intake conduit fluidically coupled to ambient fluid and having an internal cross-sectional area and an engine cylinder fluidically coupled to the intake conduit. A fluidic amplifier is disposed within the intake conduit and is fluidically coupled to the ambient fluid and engine cylinder. The amplifier is further fluidically coupled to a source of primary fluid and is configured to introduce the primary fluid and at least a portion of the ambient fluid to the engine cylinder.

Turbo or super charged intake tract diverter valve system, upstream of a throttle valve, includes a closure means (10) for a diversion aperture (4.1) in the intake tract (3) to vent pressurised gases within to a bypass path or atmosphere; the closure means having a transfer aperture (12) facilitating a net three due to a pressure differential on its opposite sides of the closure means (10) so as to close or keep closed the diversion aperture (4.1). When gas pressure on opposite sides of the closure means is equal, and when an upstream side (10.1) of the closure means (10) has a pressure greater than a downstream side (5.1), then it will open the diversion aperture (4.1). An actuation means opens a control aperture (6) to create the necessary pressure differential on the closure means (10) to thereby cause same to open the diversion aperture (4.1).

A hybrid vehicle includes: an internal combustion engine; a rotating electric machine; a planetary gear mechanism to which the internal combustion engine, the rotating electric machine and an output shaft are connected; a filter that traps a particulate matter contained in exhaust gas of the internal combustion engine; and a controller that controls the internal combustion engine and the rotating electric machine. When the controller performs a regeneration control to combust a particulate matter accumulated in the filter, the controller controls the internal combustion engine and the rotating electric machine to shift an operating point on a map representing a relationship between rotation speed of the internal combustion engine and torque generated by the internal combustion engine to a side on which generated torque is smaller so that the filter has a temperature within a regeneration temperature range enabling the regeneration control to be performed.

A device and method for regulating a compressor for an internal combustion engine. At least one actual variable is detected that characterizes a property of an air column, which is situated at an outlet of the compressor in an induction tract of an internal combustion engine, the actual variable being compared in a comparison with a comparison value, the comparison value characterizing a limit for the property of the air column, a setpoint variable being determined as a function of the result of the comparison in order to shift the actual variable in the direction or opposite direction of the comparison value, and an actuator for influencing the actual variable being operated as a function of the setpoint variable.
