Problems solved by technology

However, this is relatively labor-intensive, since the inlet section connected to the connection section is fixedly connected to the periphery of the internal combustion engine when the fresh air system is in the installed state
This makes the structure of the fresh air system more complicated
Therefore, replacing the filter element is also more complicated

Embodiment Construction

[0037] according to Figures 1 to 8 , a fresh air system 1 of which only a part is shown here, which is used to supply fresh air to the combustion chamber of an internal combustion engine (not shown here) when installed, the fresh air system 1 comprises an inlet section 2, an air filter 3 and Connect segment 4.

[0038] In the installed state, the inlet section 2 is fixedly connected to the periphery 5 of the internal combustion engine (indicated here only symbolically). Typically, the internal combustion engine is arranged in the engine compartment of the vehicle, so that the periphery 5 can be represented by an attachment point inside said engine compartment. The inlet section 2 has an inlet opening 6 through which fresh air can enter the fresh air system 1 from the environment. In this case the inlet opening 6 can in principle open directly to the environment. It is also possible that the inlet opening 6 can adjoin a correspondingly shaped air inlet (not shown here).

Abstract

The present invention relates to a fresh air system (1) for an internal combustion engine, with an inlet section (2) for fixed connection to a periphery (5) of the internal combustion engine, with an air filter (3) which has a filtering element, a filter housing (7) for fixed connection to the periphery (5) of the internal combustion engine, and a housing cover (8) for closing the filter housing (7), which housing cover is removable from the filter housing (7) for changing the filtering element, and with a connecting section (4) for fluidic connection of the inlet section (2) to the air filter (3), which connecting section is movably connected on the entry side to the inlet section (2) and is releasably connected on the exit side to the housing cover (8). A simplified changing of the filtering element is produced if, in order to change the filtering element, the connecting section (4), with the inlet section (2) connected thereto, is releasable from the housing cover (8) and is adjustable relative to the filter housing (7) to such an extent that the housing cover (8) is removable from the filter housing (7).

Description

technical field [0001] The invention relates to a fresh air system for an internal combustion engine. Background technique [0002] The internal combustion engine is equipped with a fresh air system to supply the combustion chambers of the internal combustion engine. Such a fresh air system extends in the usual manner from an inlet, through which fresh air enters the fresh air system from the environment, to an outlet section, from which the fresh air is distributed to the individual combustion chambers of the internal combustion engine. Different components of the fresh air system can be arranged between the inlet section and the outlet section. Usually, at least one air filter is arranged between the inlet section and the outlet section, which air filter has a filter element in the filter housing for filtering the fresh air supplied to the internal combustion engine. Furthermore, for example, at least one silencer, an air flow meter, a charging device and a charge air co...
