Abstract

An engine system having a turbocharger, in which an intake manifold is integrally formed, may include an intercooler that cools intake air supplied from the turbocharger, an EGR cooler that cools EGR gas supplied from an exhaust manifold, the intake manifold in which the intake air and the EGR gas supplied from the intercooler and the EGR cooler are mixed and that supplies a combustion chamber with the mixed gas, and a distribution unit that is mounted in the intake manifold and includes distribution pipes. One or each of the distribution pipes may receive the EGR gas from a connection hole through which the EGR gas is supplied and exhaust the EGR gas through an outlet towards an intake port.

First claim

What is claimed is:

1. An engine system having a turbocharger in which an intake manifold is integrally formed, the engine system comprising:
an intercooler cooling intake air supplied from the turbocharger;
an EGR cooler cooling EGR gas supplied from an exhaust manifold;
the intake manifold in which the intake air and the EGR gas supplied from the intercooler and the EGR cooler are mixed and that supplies a combustion chamber with the mixed gas; and
a distribution unit mounted in the intake manifold and including distribution pipes,
wherein one or each of the distribution pipes receives the EGR gas from a connection hole through which the EGR gas is supplied and exhausts the EGR gas through an outlet towards an intake port,
wherein an EGR gas passage receiving the EGR gas is integrally formed in the intake manifold and the EGR cooler comprises a coolant passage integrally formed at an outside of the EGR gas passage,
wherein a low temperature coolant passing through the coolant passage formed at the outside of the EGR gas passage passes through the intercooler, and
wherein the intercooler is directly connected to the intake manifold.

2. The engine system of claim 1 , wherein the distribution pipes are fixed on a fixation bracket fixed on an inner side surface of the intake manifold.

3. The engine system of claim 1 , wherein the outlet is formed at a side surface of the one or each of the distribution pipes such that the EGR gas is exhausted towards the intake port.

4. The engine system of claim 1 , wherein the one or each of the distribution pipes has a curved line shape such that the EGR gas is exhausted towards the intake port.
