Description:COOLANT FLOW MANAGEMENT SYSTEM AND A METHOD THEREOF
FIELD OF THE DISCLOSURE
[0001] This invention generally relates to coolant system of vehicles, in particular relates to a coolant flow management system that helps in circulating controlled flow of coolant to regulate temperature of engine oil of vehicles based on real time requirements of the vehicle’s engine.
BACKGROUND
[0002] Coolant flow management is a critical requirement in modern internal combustion engines to optimize thermal performance, fuel efficiency, and engine durability. In heavy-duty diesel engines, maintaining an optimal temperature range is essential to ensure proper combustion, reduce emissions, and enhance component longevity. However, conventional cooling systems rely on a constant coolant flow rate, irrespective of engine load and operating conditions. This results in excessive energy consumption by the coolant pump, leading to a fuel efficiency penalty and unnecessary thermal losses.
[0003] In existing designs of cooling system, , Claims:We Claim:
1. A coolant flow management system (100) comprising an oil cooler (202) integrated in an oil cooling circuit of a vehicle and configured to regulate temperature of engine oil by circulating coolant through the cooling circuit using a coolant pump (204), the system (100) characterised in that:
one or more temperature sensors (102) integrated within the oil cooling circuit and configured to monitor temperature of the engine oil in real time;
a control valve (106) operatively coupled between the oil cooler (202) and the coolant pump (204), wherein the control valve (106) is configured to regulate flow of the coolant towards the coolant pump (204) based at least on the temperature of the engine oil; and
an electronic control unit (ECU) (104) operatively coupled to the one or more temperature sensors (102) and the control valve (106), wherein the ECU (104) is configured to:
determine whether the temperature of the engine oil determined by the one or more temperature sensors (102) is more or less than
