Embodiment Construction

[0048] exist figure 1 In , the invention is described in detail, for example with the aid of a six-cylinder turbocharged engine, where it should be pointed out that the function of the engine braking device according to the invention is independent of the number of cylinders and of the charging system, for example also without booster Compression engine use.

[0049] The six cylinders C1 , C2 , C3 , C4 , C5 , C6 of the internal combustion engine 1 are connected via intake ducts (not further shown) to an intake air collector 2 , which starts from the air filter 3 via the turbocharger 4 compressor part C and supply charge air through the charge air cooler 5. The exhaust valve of the internal combustion engine 1 opens into an exhaust system 6 , wherein the exhaust gas is conveyed in a conventional manner via a turbine part T of a turbocharger 4 and discharged via a muffler 7 .

[0050] The engine brake device 8 has a tubular pressure tank 9 (brake pressure accumulator pipe), an...

Abstract

The invention relates to a method for operating internal combustion engine, particularly multi-cylinder internal-combustion engine, and an engine brake mechanism. In a brake valve, each cylinder has, additionally to the input and exhaust valves, at least one brake valve which leads into a common container (brake Rail). The brake valve is at least opened once before, at the beginning and / or during the compression phase of the cylinder. In order to regulate the brake power in a more simple way, the brake power of the engine brake mechanism is controlled by changing the control times of the brake valve.

Description

technical field [0001] The invention relates to a method for operating an internal combustion engine, in particular a multi-cylinder internal combustion engine, and to an internal combustion engine for carrying out the method, with an engine braking device with at least one valve per cylinder, preferably connected to an intake valve and an exhaust valve. valve additional brake valve, which leads into a common pressure tank (brake pressure reservoir), wherein the brake valve is activated before, at the beginning and / or during the cylinder compression phase under engine braking Open it at least once. Background technique [0002] In particular, braking systems integrated into motor vehicles such as commercial vehicle engines are gaining in importance because these systems represent cost-effective and space-saving additional braking systems. However, increasing the specific power of modern commercial vehicle engines also requires increasing the braking power to be achieved. ...
