Abstract:
A system according to the principles of the present disclosure includes a temperature estimation module and a fuel control module. The temperature estimation module estimates a piston temperature associated with a cylinder based on engine operating conditions. The fuel control module controls at least one of injection timing associated with the cylinder, injection pressure associated with a cylinder, injection location associated with a cylinder, and a number of injections per engine cycle associated with the cylinder based on the piston temperature.
