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

A method and apparatus for boosting the pressure of the air charge to an internal combustion engine, which has an exhaust gas recirculation (EGR) system and a turbocharger. The EGR system is arranged to recirculate exhaust gas from an engine exhaust outlet passage to the engine air inlet passage. An exhaust gas bypass passage is arranged to divert exhaust gas that would otherwise reach the turbocharger's impeller. The engine has a single, unitary control valve with a valve inlet arranged to receive exhaust gas from the engine exhaust outlet passage, and three valve outlets. A first of the valve outlets provides exhaust gas to the EGR system for recirculation to the engine air inlet passage, a second of the valve outlets provides exhaust gas to the exhaust gas bypass passage and a third of the outlets provides exhaust gas to the impeller.

Pressure boosted IC engine with exhaust gas recirculation

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

This invention relates to a method of cooling an internal combustion engine, to an internal combustion engine assembly. The invention provides an internal combustion engine which has a primary and a secondary flow of coolant together with a method of cooling such and engine. The secondary flow of coolant is injected into the primary flow of coolant in dependence upon a variable provided by a sensor, which provides an indication of the temperature of the engine body in the region where the secondary flow of coolant mixes with the primary flow of coolant.

Internal combustion engine cooling system

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.
