Method for improving the response relationship of an exhaust gas turbo charger of an internal combustion engine

摘要

A method for improving the response relationship of an exhaust gas turbo charger during intermittent operation of a combustion engine having compressed air includes injecting a follow on injection after a principal injection. During a positive load change, an idling operation, or a partial load operation, the follow on injection is delayed to a relatively late time point such that a complete vaporization of the combustion fuel in the cylinder is accomplished without effecting as well a combustion of the mixture of combustion fuel vapor and oxygen remainder of the exhaust gas in the cylinder. The mixture of combustion fuel vapor and exhaust gas is oxidized first upon passage of the mixture through an exhaust gas handling component between the outlet valve and the inlet of an exhaust gas turbine of an exhaust gas turbo charger.
