Abstract
A method of cooling an internal combustion engine having a first group of fuel injectors supplying fuel to a first group of injectors and a second group of fuel injectors supplying fuel to a second group of cylinders, the method including the steps of measuring the temperature of the engine, determining if the temperature of the engine exceeds a predetermined temperature threshold, shutting off the first group of fuel injectors to the first number of cylinders where air is pumped through the first number of cylinders to cool the first number of cylinders, energizing the second group of fuel injectors to the second group of cylinders to provide an air/fuel mixture to the second group of cylinders to drive the engine, shutting off at least one of the second group of fuel injectors to the second group of cylinders to pump air through at least one of the second group of cylinders.
