A method (100) of operating an internal combustion engine (1) is disclosed, the internal combustion engine (1) comprising a plurality of cylinders (c1 - c5). The method (100) comprises the steps of operating (110) a first set (s1) of cylinders (c1 - c3) in...

The method involves controlling a brake flap (20) under operating conditions of an internal combustion engine (1) for defined increase of an exhaust back pressure in preset manner. The exhaust back pressure is maintained below a threshold, which excludes a...

The controlling method involves the use of an EGR valve arranged upstream of the brake flap (6) and recirculation line that connects the exhaust gas system to the engine intake system. The EGR valve (13) is opened in dependence upon the predetermined opera...

A control system and method for engine braking for a includes an engine braking control and at least one exhaust valve actuator (610) responsive to demands from the braking control for causing the exhaust valve (618) to open. The braking control is configu...

A system and method for braking a vehicle 12 having a variable compression ratio engine 14 and a compression braking system 16 is disclosed. The system 10 is adapted to utilise the variable compression ratio engine 14 and the compression braking system 16 ...

A method of engine compression release braking with avoidance of turbine overspeed is disclosed. Initially, an electronic control module (17) determines whether a turbine overspeed condition is present. If an overspeed condition is present, then the blow d...

2.1 Usually, the behavior of an engine is measured by placing the engine in a test cell and connecting it to a dynamometer. 2.2 A method is proposed that utilizes an engine control unit (32) of the engine (12), by means of which the fuel supply and one or ...
