Abstract:
1. A transient engine performance adaptation method executing the steps of: conducting transient testing, during which an engine is operated in a transient state by making changes to control values of control factors supplied to the engine and its output is captured; capturing engine output data produced by the transient testing and creating a transient engine model of the tested engine based on the relationship between the output data and data concerning the control factors supplied to the engine; obtaining control values of control factors that satisfy transient performance targets required of said engine, using the transient engine model that has been created; confirming whether the required transient performance targets are satisfied by conducting transient testing by supplying the control values obtained from the transient engine model to the real engine; and creating control software for a control circuit controlling the engine if the confirmation step finds that the required transient performance targets are satisfied, wherein the transient performance targets are set on a condition that the step of conducting the transient testing is executed by changing control values of the control factors in accordance with a prescribed standardized transient operation mode, and the step of conducting the transient testing is executed, when there are a plurality of the prescribed standardized transient operation modes, in a single transient operation mode that covers changing patterns of control values of the control factors of the plurality of transient operation modes.
