Methods and devices are disclosed for introducing a compressor bypass flow that is returned from location that is downstream of a pressure source of an internal combustion engine to an air filter housing that is located upstream of the pressure source.

Compressor bypass flow arrangement

A turbocharged internal combustion engine system includes at least one high pressure turbocharger system mounted on-engine and at least one low pressure turbocharger system mounted off-engine. An intercooler can further be mounted off-engine with the low pressure turbocharger and an aftercooler can be mounted on-engine with the high pressure turbocharger.

A gaseous fuel mixer for an internal combustion engine includes a check valve. The check valve includes a check valve member that induces mixing of a gaseous fuel flow and an intake air flow as the gaseous fuel flow and intake air flow move or pass from an upstream side of the check valve to a downstream side of the check valve.
