Internal combustion engine with exhaust gas turbocharger

['■ —- ■ <■ »■■ w-y ■■■ * ■» »■ * g

The invention relates to an internal combustion engine with exhaust gas turbocharging, in which the turbocharger, charge air cooler and the associated lines are attached to the internal combustion engine. Both the lines between the individual units and the lines from the exhaust line to the turbocharger and from the supercharger to the intake line of the internal combustion engine are detachable. This has the disadvantage that when repairing or maintaining the turbocharger or part of it, a number of lines have to be loosened in order to reconnect them after the repair has been carried out. In supercharged diesel engines, the space and weight share of the exhaust and charge air system increases with increasing degrees of supercharging.
This also results in the following disadvantages:

a) Maintenance and repair of the engine are additional made more difficult because vulnerable by the exhaust and charge air system Engine parts. Covered and only after dismantling the exhaust and charge air system become accessible. ,

b) The operationally safe attachment of the individual elements of the exhaust and charge air system to the engine is increasing with increasing Weight and the increasing number of parts are becoming more and more complex and difficult. '

e) The supply of the exhaust and charge air system with lubricant " and coolants requires extensive pipelines, which increase the cost and also the susceptibility to failure. In addition, the image of the engine is impaired in terms of good industrial form.

B? I the known constructions are the individual parts of the exhaust gas and charge air system by each assigned to these parts Brackets attached to the engine. The supply of coolants and additives takes place via separately laid pipelines. When the exhaust and charge air systems are dismantled, there is a large number to resolve connections.

The present invention has set itself the task of reducing the sensitivity of turbocharging systems for internal combustion engines Simplify expected maintenance and repairs without lengthy and laborious dismantling and reassembly of the lines and to carry out devices while avoiding long downtimes of the internal combustion engine and the structural disadvantages to fix.

To solve this problem, the invention provides the exhaust gas and to mount the charge air system on supercharged internal combustion engines on a special framework, with the individual lines between the turbocharger, intercooler and to the charge air ducts are combined into one unit, and this scaffolding is modular to be built on the internal combustion engine, in which case only the connections to the exhaust and intake line and the coolant and monitoring lines are to be connected.

As an extension of the concept of the invention, the framework of the supporting structure for the exhaust gas turbocharger, charge air cooler and accessories are used as a line for operating and coolant. With this arrangement it is possible to add the supporting structure to be more compact and to make mounting and dismounting even easier.

The invention is shown in the drawings as an example.

Figure 1 shows a rare view of an internal combustion engine Turbo-charging, in which a support frame with four turbochargers is placed on the internal combustion engine.

FIG. 2 shows the supporting structure of the internal combustion engine according to FIG in the dismantled state in the side view.

Figure 3 shows the support structure according to Figure 2 in plan view.

In the drawings, 1 denotes the internal combustion engine, with 2 is the intake line, with 3 denotes the exhaust line. 4 is the connection of the intake line with the charge air ducts for the turbocharger, while 5 is the actual supporting structure represents which with supports 6 on the "cylinder heads" of the internal combustion engine 1 rests. The charge air is sucked in by the turbocharger via filter 9 and below via the charge air ducts 1o Cooling through the intercooler 8 into the intake line 2 promoted. The intake line 2 is connected to the charge air line Vo by means of a socket connection. The exhaust gases from the turbocharger will. In each case two superchargers combined, led into an exhaust gas pot. The lines 11 are used to supply the exhaust gas turbocharger with coolants and lubricants and to control and monitoring of the loader. Some of these lines are in the The longitudinal and transverse spars of the supporting structure are laid or the spars of the supporting structure 5 are themselves designed as pipelines, so that part of the lines and the associated individual fastening elements be saved.
