ABSTRACT:
This disclosure relates to a turbocharged internal combustion engine. The exhaust manifold of the engine is divided into sections, and the engine exhaust from one of the sections is recirculated to the intake manifold. The engine cylinders that feed the EGR exhaust manifold section alternate in the engine firing order with the other cylinders, thereby providing a substantially uniform flow of exhaust gas to all of the cylinders. The turbine of the engine turbocharger is divided into two sections, one having a smaller flow area than the other. The turbine section having the smaller flow area is connected to receive the exhaust gasses from the exhaust manifold section that also supplies the EGR.
