PROCEDURE AND MECHANISM FOR THE COOLING OF AN INTERNAL-COMBUSTION ENGINE OF A MOTOR VEHICLE

APPARATUS AND METHOD FOR INTERNAL COMBUSTION ENGINE COOLING SYSTEM

In the field of cooling of internal combustion engines a known characteristic of thermostatic flow control valves is their lagging control response to variable rates of internal heat generation in the engine. Further, there is a thermal inertia effect due to engine mass and internal fluids masses which masks imbalances between instantaneous internal heating and cooling rates, in many cases allowing internal temperatures to rise excessively and pre-ignition damage or other heat-related component damage to occur to the engine system. The invention seeks to overcome these known characteristics using simple apparatus with a method to effect improved operation of the cooling system.

When the coolant temperature is equal to or higher than a fan operation temperature at which the operation of the electric fan is started, the first flow rate correction means increases the discharge flow rate of the electric water pump in accordance with an increase in the coolant temperature.

Cooling device for internal combustion engine of vehicle and control method thereof

The cooling device according to the present invention includes an electric water pump for circulating cooling water through an internal combustion engine of a vehicle, and controls the discharge flow rate of the electric water pump as follows. Until the cooling water temperature. TW reaches a warm-up completion determination temperature, the cooling device increases the discharge flow rate along with an increase of the cooling water temperature TW. After the cooling water temperature TW reaches the warm-up completion determination temperature, the cooling device controls the discharge flow rate so as to bring the combustion chamber wall temperature TCYL toward a target temperature. Thereby, the cooling device can warm up the internal combustion engine more efficiently, and improve the combustion performance of the internal combustion engine after the completion of warm-up.

Engine cooling apparatus

An engine cooling apparatus suitable for use in a vehicle shortens engine warm-up time without decreasing the heat-radiation capacity of a radiator. A shroud is disposed between a radiator and a water-cooled engine. A first air passage for blowing air toward the engine and its auxiliaries is formed in the upper side of the shroud, and a second air passage for discharging air having passed through the radiator to outside the engine compartment is formed in the lower side of the shroud. Accordingly, air is prevented from directly striking the engine and from passing around to the upstream side of the radiator through gaps between the walls of the engine compartment and the radiator. Thus the engine warm-up time is shortened without reducing the heat-radiation capacity of the radiator.

The thermostatic valve is acted upon by current from the vehicle start as long as the distance covered after the vehicle start is shorter than the limit distance.

Thermostat abnormal state detecting apparatus

When a temperature of cooling water detected by a water temperature sensor is, for instance, higher than, or equal to degrees, and is smaller than degrees, an abnormal state judging unit judges that an engine is under semiwarming-up condition, and then forcibly drives an electric motor fan so as to forcibly cool cooling water contained in a radiator. After the abnormal state judging unit has forcibly driven the electric motor fan, this abnormal state judging unit calculates a difference between the cooling water temperature detected by the water temperature sensor and a predicted cooling water temperature. When the calculated temperature difference is smaller than a predetermined abnormal state judging value, the abnormal state judging unit judges that a thermostat provided in a cooling water circulating path is brought into an abnormal valve opening state.

Method (embodiments) and system for engine cooling system control

FIELD: machine building. SUBSTANCE: invention relates to vehicle engine cooling system. Disclosed are methods and systems for improving evaluation of coolant level of an engine in order to reduce engine overheating. Liquid level in the expansion tank of the coolant can be determined based on the liquid level in the hollow vertical tube, connected with possibility of hydraulic communication with the tank in the upper and lower parts, wherein liquid level in the tube can be determined based on the ultrasonic signal echo signal time emitted by the sensor located in the compartment in the lower part of the vertical tube. Output data of the sensor are compensated by correction based on the vehicle motion parameters in order to compensate for deviation of the liquid level in connection with fluid oscillations caused by movement. EFFECT: invention provides higher accuracy of determining the level of coolant volume and operating parameters of the engine to prevent overheating of the engine. 19 cl, 21 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 709 395 C2 (51) МПК F01P 11/18 (2006.01) G01F 23/296 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК F01P 11/18 (2019.08); G01F 23/296 (2019.08) (21)(22) Заявка: 2015154100, 17.12.2015 (24) Дата начала отсчета срока действия патента: Дата регистрации: 17.12.2019 (73) Патентообладатель(и): Форд Глобал Текнолоджиз, ЛЛК (US) 26.12.2014 US 14/583,366 (43) Дата публикации заявки: 22.06.2017 Бюл. № 18 (45) Опубликовано: 17.12.2019 Бюл. № 35 2 7 0 9 3 9 5 R U (54) СПОСОБ (ВАРИАНТЫ) И СИСТЕМА УПРАВЛЕНИЯ СИСТЕМОЙ ОХЛАЖДЕНИЯ ДВИГАТЕЛЯ АВТОМОБИЛЯ (57) Реферат: Изобретение относится к системе охлаждения датчиком, расположенным в отсеке в нижней двигателя автомобиля.

Thermostat malfunction detecting system for engine cooling system

A malfunction of a thermostat in a coolant circulating path is detected from an engine side coolant temperature in consideration of the following behavior of the coolant temperature. When an open-malfunction occurs, the coolant temperature becomes different considerably from that in the normal time in the temperature range in which the thermostat is to be normally closed. When a closure-malfunction occurs, the coolant temperature becomes different considerably from that during the normal time in the temperature range in which the thermostat is to be normally opened. Alternatively, the malfunction may be detected from a difference between the engine side coolant temperature and a radiator side coolant temperature.

Engine cooling system

In the cooling system of a vehicle engine, a thermostatic valve controlling the flow of coolant to a radiator or via a radiator by-pass can be switched to either an upper or lower threshold level determined in accordance with engine and/or environmental conditions. A fan 17 associated with the radiator is switched on when the detected coolant temperature T KW exceeds a first threshold value T KWSOLL1 and the thermostatic valve has been switched to the lower threshold level. The fan 17 can also be switched on when the coolant temperature T KW exceeds a second level T KWSOLL2 and the thermostatic valve has not been switched to the lower threshold level. Look-up tables 21, 25 can be used to determine the actual output level of the fan.
