Method and apparatus for controlling fuel to an engine during coolant failure

A method of cooling an internal combustion engine having a plurality of cylinders, a plurality of fuel injectors, the method of cooling comprising;

• measuring the temperature of an engine;
• determining if the temperature of the engine exceeds a predetermined temperature threshold;
• shutting off a first number of fuel injectors to a first number of cylinders if the temperature of the engine exceeds the predetermined threshold;
• pumping air through the first number of cylinders to cool the engine;
• providing fuel to a second number of cylinders via a second number of fuel injectors;
• shutting off at least one of the second number of fuel injectors to allow at least one of the second number of cylinders to cool;
• and
• alternating the shut off of the at least one of the second number of fuel injectors among the group of the second number of fuel injectors.

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 comprising:

• 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 wherein 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;
• and
• 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 cylinder of the second group of cylinders.
