Abstract:
The invention relates to a valve timing for an internal-combustion engine with a variable control of the outlet valve. For reducing the HC-emissions, it is suggested according to the invention to adjust the closing of the outlet valve toward "early". This adjustment must be carried out to such an extent that the outlet valve will be closed before the piston has reached the upper dead center.
