Abstract: An intake system of an internal combustion engine of a vehicle includes: an intake manifold configured to be fluidly coupled to a throttle valve and including intake runners for cylinders, respectively, of the internal combustion engine; and a plenum that includes a flange configured to receive gas from a valve of the vehicle, that is fixed to the intake manifold, and that includes apertures configured to flow gas from the plenum into the intake manifold one of: between ones of the intake runners; and directly into the intake runners.

Abstract: A mass airflow sensor according to the present disclosure includes a housing, a sensor element, and a flow deflector. The housing defines an airflow passage configured to receive air flowing in a first direction. The sensor element is disposed in the airflow passage and generates a signal indicating a mass flow rate of air flowing through the airflow passage. The flow deflector is disposed in the airflow passage downstream of the sensor element, extends from an inner wall surface of the airflow passage, and is configured to inhibit air flow through the airflow passage in a second direction that is opposite of the first direction.

Abstract: A gas compressor assembly configured to pressurize an airflow received from the ambient for delivery to an internal combustion engine having a cylinder includes a compressor housing. A compressor wheel is disposed inside the compressor housing and configured to pressurize the airflow. A compressor bypass is configured to direct the pressurized airflow away from the cylinder. A pressure relief valve is configured to selectively open and close the compressor bypass to thereby limit pressure of the pressurized airflow and minimize surge of the compressor wheel. A baffle arranged inside the compressor bypass is configured to dissipate energy of a sound wave generated by the pressurized airflow upon an initial opening of the pressure relief valve. An internal combustion engine employing such a turbocharger is also disclosed.
