Method and system for controlling the amount of fuel in connection to operating an internal combustion engine

A system for controlling an amount of fuel in connection to operating an internal combustion engine based upon an engine boost pressure and engine operational conditions, said engine operational conditions comprising engine speed and ambient air pressure, using a map function, said system comprising:

• means for, for low and/or negative engine boost pressures, using a map function specifying torque values so as to determine an available torque based upon an exhaust gas smoke limit taking driveability into account;
• and
• means for determining a maximum allowable fuel amount based upon said determined available torque considering losses and combustion efficiency.
