Abstract

In an internal combustion engine for motor vehicles with an engine shutdown driven capability, wherein the engine has intake and exhaust valves with a variable timing valve actuating system permitting the generation of an engine braking torque depending on the state of vehicle operation, the intake and exhaust valves are controlled during shutdown engine driven operation such that at least on type of valves, that is either all the intake or all the exhaust valves remain closed.
