Method of managing engine torque upon loss of engine coolant

An engine torque management system of a V-style engine utilizes a cylinder head metal temperature sensor in each cylinder head to detect a temperature. When the sensor temperature rises above a threshold value for a particular time period, the response software shuts down the fuel injection of a ban...

More Information
Summary:An engine torque management system of a V-style engine utilizes a cylinder head metal temperature sensor in each cylinder head to detect a temperature. When the sensor temperature rises above a threshold value for a particular time period, the response software shuts down the fuel injection of a bank of cylinders in which the sensor is installed. Cool, uncombusted intake air cools that bank and an external fan blows air over that bank. If the sensor in the second bank of cylinders rises above the threshold, the fuel injection on that bank shuts off to undergo cooling while the fuel injection on the first bank restarts. Alternation between the two banks occurs to maintain the desired level of torque demanded by the vehicle driver.
