Abstract
In an internal combustion engine with a motor block and a charge fluid cooler mounted thereon wherein the motor block comprises a cylinder block with a cylinder head mounted thereon, the charge fluid cooler is attached to the cylinder head via an outlet manifold flange and a cylinder head flange which are joined by at least one first screw connection via a spacer member arranged at a side of a charge fluid inlet passage extending through the flanges and at least one second screw connection is provided for attaching the charge fluid cooler to the cylinder block via a second screw connection providing for a partially rigid and a partially elastic support.

An internal combustion engine (100) including a motor block (10) with a charge fluid cooler (1) mounted thereon,
- the motorblock (10) comprising a crankcase with a cylinder block (3) and a cylinder head mounted onto the cylinder block (3) and the charge fluid cooler (1) comprising a cooler block and a cooler housing (5) with an outlet manifold (9),
- the cooler housing (5) having a first support part for supporting the charge fluid cooler (1) on the cylinder head (2) by means of a first screw connection (30), the first support part including a support opening (31) and the outlet manifold (9) including an outlet manifold-side flange connecting surface (20.1) for forming a flange connection (20) with a cylinder head-side flange connecting surface (20.2),
- the flange connection (20) between the outlet manifold (9) and the cylinder head (2) being held together by the first screw connection (30), which is disposed at the side of a cross-section of a charge fluid inlet passage (12) extending through the flange connection (20) and
- the cooler housing (5) having a second support part (72) for mounting the charge fluid cooler (1) to the cylinder block (3) by means of a second screw connection (60),
- the support opening (31) being arranged at the cooler housing (5) in spaced relationship from the outlet manifold-side flange connecting surface (20.1) so that an accommodation space (A) is formed between the outlet manifold side flange connecting surface (20.1) and the mounting opening (31) which accommodates space (A) has a length exceeding a length (B) of the support opening (31), a load accommodating spacer sleeve (34) being disposed in the accommodation space (A) with the first screw connection (30) extending through the spacer sleeve (34),
- the flange connection (20) being established with a relief gap (22) remaining between the manifold-side (20.1) and the cylinder head-side (20.2) flange connecting surfaces with a seal disposed in the relief gap (22), and
- the second support part (72) being formed by a partially, that is in one direction, rigid and partially, that is in another direction, elastic support disposed between the second support part (72) and the second screw connection (60).
A charge fluid cooler (1) with a cooler block and a cooler housing (5) provided with an outlet manifold (9), the cooler housing (5) comprising:
- a first support part for mounting the charge fluid cooler (1) to a cylinder head (2) by means of a first screw connection (30) wherein the first support part includes a support opening (31),
- the outlet manifold (9) includes an outlet manifold-side flange connecting surface (20.1) for forming a flange connection (20) with a cylinder head-side flange connecting surface (20.2), wherein the flange connection (20) between the outlet manifold (9) and the cylinder head (2) of an internal combustion engine (100) is held together at one side of a cross-section of an inlet passage (12) extending through the flange connection (20) by a first screw connection (20), and
- the cooler housing (5) includes a second support part (72) for mounting the charge fluid cooler (1) by means of a second screw connection (60) to a cylinder block (3) of an internal combustion engine (100), wherein by means of the second support part (72) a support structure is formed for the charge fluid cooler (1) at the second screw connection (60),
- the support opening (31) being arranged at the cooler housing (5) so as to form an accommodation space (A) to the manifold side flange connecting surface (20.1) wherein the length of the accommodation space A is greater than the length (B) of the support opening (31) and
- the accommodation space (A) is provided for accommodating a spacer sleeve (34) serving the first screw connection (30), and wherein
- the support formed by the second support part (72) is a part-side rigid and a part-side elastic support member for disposition between the second support part (72) and the second screw connection (60).
