Abstract

Abstract The invention joins the intake module or intake tube to the engine with the aid of a displaceable retaining element. The retaining element, which in the mounted state is under initial tension, is braced against an engine retention face associated with the engine and against at least one counterpart intake module retention face joined to the intake module or intake tube. Because of the displaceability of the retaining element, the expense and effort of mounting and dismantling the intake module or intake tube to the engine by screws are substantially reduced. The engine is intended in particular for motor vehicles.

Claim 1
Independent Claim 114 words
An internal combustion engine with an intake module or intake tube, wherein the intake module or intake tube is fastened to the engine by a fastening means (10) in a retention direction (30), the fastening means (10), includes at least one retaining element (33, 33z) that is under spring force in a mounted state and that is braced on one side on at least one retention face (32) associated with the engine (4) and oriented substantially in a direction of the retention direction (30) and on another side on at least one counterpart retention face (34) associated with the intake module (6) or intake tube and oriented substantially counter to the retention direction (30).
Claim 2
Dependent Claim 114 words
An internal combustion engine with an intake module or intake tube, wherein the intake module or intake tube is fastened to the engine by a fastening means (10) in a retention direction (30), the fastening means (10), includes at least one retaining element (33, 33z) that is under spring force in a mounted state and that is braced on one side on at least one retention face (32) associated with the engine (4) and oriented substantially in a direction of the retention direction (30) and on another side on at least one counterpart retention face (34) associated with the intake module (6) or intake tube and oriented substantially counter to the retention direction (30).
Claim 3
Dependent Claim 28 words
The engine in accordance with claim 1, in which the retaining element (33, 33z) is braced against a plurality of retention faces (32) associated with the engine (4).
Claim 4
Dependent Claim 33 words
The engine in accordance with claim 1 in which the retaining element (33, 33z) is braced against a plurality of counterpart retention faces (34) associated with the intake module (6) or intake tube.
Claim 5
Dependent Claim 33 words
The engine in accordance with claim 2 in which the retaining element (33, 33z) is braced against a plurality of counterpart retention faces (34) associated with the intake module (6) or intake tube.
Claim 6
Dependent Claim 18 words
The engine in accordance with claim 1, in which the retaining element (33, 33z) is an elastic element.
Claim 7
Dependent Claim 47 words
The engine in accordance with claim 1, in which the spring force arises by means of a displacement of the retaining element (33, 33z) oriented substantially crosswise to the retention on direction (30), and in particular by a substantially linear displacement of the retaining element (33, 33z).
Claim 8
Dependent Claim 27 words
The engine in accordance with claim 1, in which the retaining element (33, 33z) has an approximately U-shaped or bracketlike cross section, at least in one portion.
Claim 9
Dependent Claim 39 words
The engine in accordance with claim 1, in which when the intake module (6) or intake tube has been removed from the engine (4), the retaining element (33, 33z) is coupled to the intake module (6) or intake tube.
Claim 10
Dependent Claim 35 words
The engine in accordance with claim 1, in which when the intake module (6) or intake tube has been removed from the engine (4), the retaining element (33, 33z) is coupled to the engine (4).
Claim 11
Dependent Claim 25 words
The engine in accordance with claim 1, in which the retention face (32) is provided on a stop piece (66) associated with the engine (4).
Claim 12
Dependent Claim 17 words
The engine in accordance with claim 10, in which the stop piece (66) is a bolt (80).
Claim 13
Dependent Claim 31 words
The engine in accordance with claim 1, in which the counterpart retention face (34) is provided on a counterpart stop piece (70) associated with the intake module (6) or intake tube.
Claim 14
Dependent Claim 75 words
The engine in accordance with claim 1, in which at least one chamfer (76) associated with the engine (4) is provided, said at least one chamfer is made in such a way that once the intake module (6) or intake tube has been mounted on the engine (4), the spring force is generated by a displacement of the retaining element (33, 33z), by means of a substantially linear displacement of the retaining element (33, 33z).
Claim 15
Dependent Claim 79 words
The engine in accordance with claim 1, in which at least one chamfer (76) associated with the intake module (6) or intake tube is provided, said at least one chamfer is made in such a way that once the intake module (6) or intake tube has been mounted on the engine (4), the spring force is generated by a displacement of the retaining element (33, 33z), by means of a substantially linear displacement of the retaining element (33, 33z).
Claim 16
Dependent Claim 77 words
The engine in accordance with claim 1, in which at least one chamfer (76) associated with the retaining element (33, 33z) is provided, said at least one chamfer is made in such a way that once the intake module (6) or intake tube has been mounted on the engine (4), the spring force is generated by a displacement of the retaining element (33, 33z), by means of a substantially linear displacement of the retaining element (33, 33z).
Claim 17
Independent Claim 126 words
