Abstract

An internal combustion engine equipped with a turbocharger (5) including a turbine (40) and a compressor (27) that are arranged in a coaxial relationship, the internal combustion engine includes an exhaust pipe (41) extending from an outlet (59) of the turbine along a side of the compressor, an actuator (90) attached to a part of the compressor for controlling a flow path of the turbocharger, and a fluid pipe (76, 79) conducting fluid and extending through a space defined between the exhaust pipe and the actuator.

Claims

1. An internal combustion engine equipped with a turbocharger, the turbocharger including a turbine and a compressor that are arranged in a coaxial relationship, the internal combustion engine comprising:

an exhaust pipe extending from an outlet of the turbine along a side of the compressor;

an actuator attached to a part of the compressor for controlling a flow path of the turbocharger; and

a fluid pipe conducting fluid and extending through a space defined between the exhaust pipe and the actuator.

2. The internal combustion engine as defined in claim 1, wherein the fluid pipe is an intake pipe connected to an outlet of the compressor.

3. The internal combustion engine as defined in claim 2, wherein the exhaust pipe extends obliquely from the outlet of the turbine, and passes along a lower side of the compressor, and

the intake pipe includes an upstream part extending downward from the outlet of the compressor, and a downstream part extending away from the turbine, the actuator being positioned above the downstream part and on a side of the upstream part remote from the turbine.

4. The internal combustion engine as defined in claim 3, wherein the turbocharger comprises a turbine housing accommodating a turbine wheel of the turbine therein and a compressor housing accommodating a compressor wheel of the compressor therein, and

wherein the upstream part of the intake pipe consists of a tubular part integrally formed with the compressor housing, and the actuator is supported by the compressor housing via a bracket integrally formed with the compressor housing.

5. The internal combustion engine as defined in claim 4, wherein the actuator includes a case attached to the bracket of the compressor housing, a drive rod extending from the case toward the turbine, and a drive unit received in the case and configured to axially actuate the drive rod, the bracket comprising a plate member having a major plane extending substantially perpendicularly to an axial line of the turbocharger, the case being attached to the bracket such that the drive unit is disposed on a side of the bracket remote from the turbine.

6. The internal combustion engine as defined in claim 5, wherein the bracket has an opening formed therein, and the case of the actuator is attached to the opening of the bracket, the drive rod of the actuator extending through the opening from the drive unit toward the turbine.

7. The internal combustion engine as defined in claim 1, wherein the exhaust pipe includes a catalytic converter.

8. The internal combustion engine as defined in claim 5, wherein an end of the drive rod remote from the case is connected to a wastegate valve of the turbine.
