This invention relates to a method of cooling an engine for an automobile. The method operates using a predictive, feed-forward element combined with a fuzzy logic feedback controller to achieve accurate control over engine temperature. The fuzzy logic feedback is only utilized in the event that the predictive control results in a cylinder head temperature outside a predetermined range.

Method of engine cooling

The present invention relates to a method and apparatus for cooling intake air prior to entry into a combustion chamber of a boosted internal combustion engine. The invention provides an air intake system comprising a cooler disposed in an intake passage downstream of a charger; a bypass passage for communication between a portion of said intake passage located upstream of said cooler and a portion of said intake passage located downstream of said cooler so as to allow a flow of air discharged from the charger to bypass the cooler; a bypass control valve disposed in said bypass passage to open and close the bypass passage and a flow restriction disposed in the bypass passage limiting the flow in the event that the bypass control valve remains in an open position.

Air intake cooling system and method

An engine thermal management system and method for a vehicle engine that allows for reduced coolant flow and energy consumption by the system, while avoiding excessive critical metal temperatures in the engine. The engine includes a coolant inlet in a head and a coolant outlet in a block. A variable speed pump pushes the coolant into the head inlet. A multi-port valve receives the coolant exiting the engine block and selectively routes it to various system components. The speed of the pump and the valve are electronically controlled by a control module, based upon various engine and vehicle operating conditions.

Engine thermal management for internal combustion engine

An engine cooling system and method applicable to a diesel engine in a vehicle. A control module, via a single multi-port valve, controls the coolant flow through a radiator, heater and oil cooler based upon engine operating conditions.
