Patent ID: 8505296

Claim:
A system for controlling an engine, comprising: a turbocharger; at least one adjustable camshaft; a direct injector for injecting fuel to at least a cylinder of said engine; an automatic transmission coupled to said engine; and a controller that operates said engine such that a rate of temperature change of said engine is less than a first amount when an engine temperature is less than a first threshold temperature, said controller operating said engine such that said rate of temperature change of said engine is less than or equal to a second amount when said engine temperature exceeds said first threshold temperature, and said second amount less than said first amount, said controller limiting boost of said turbocharger when said engine temperature exceeds said first threshold temperature, said controller adjusting a position of said at least one adjustable camshaft when said engine temperature exceeds said first threshold temperature, said controller adjusting the amount of fuel injected by said direct injector when said engine temperature exceeds said first threshold temperature, and said controller adjusting shifting of said automatic transmission when said engine temperature exceeds said first threshold temperature.
