Abstract
In an engine braking method and an internal combustion engine including an engine braking arrangement, wherein the engine has high pressure and low pressure exhaust gas turbochargers connected in series, with a bypass () around the high-pressure compressor allowing the air mass flow selectively to bypass the high pressure compressor which is arranged near the engine, and bypasses around both turbines permitting the exhaust gas mass flow selectively to bypass the high-pressure exhaust gas turbine which is near the engine and also the low pressure turbine the intake air and the exhaust gas flow are controlled so as to accurately provide for a desired engine braking power for example for maintaining a desired vehicle speed.
