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. ...
