Internal combustion engine with charge air cooling

摘要

An internal combustion engine has a cylinder head having at least one cylinder. A cover is connected to the cylinder head and covers the cylinder and related valve train components. An exhaust gas turbocharger powered by the engine's exhaust system delivers compressed gasses to the intake system. An exhaust gas recirculation system branches off from the exhaust system downstream of the turbocharger and feeds into the intake system upstream of the turbocharger. A coolant-fed charge air cooler is disposed between the cylinder head and the cover, and at a point that is a geodetically highest point in the intake system when the internal combustion engine is in an installed position. This configuration prevents any liquid that has condensed out of the charge air during cooling from collecting in the cooler and/or in the intake system between the cooler and the at least one cylinder.

主权项

1. An internal combustion engine comprising:
a cylinder head having a cylinder; a fuel injector associated with the cylinder; a cover connected to the cylinder head to cover a valve and having an aperture through which the injector passes; an intake system supplying the cylinder with charge air; and a coolant-fed charge air cooler arranged in the intake system, at least a portion of the charge air cooler located between the cylinder head and the cover.
