“…However, the article does not analyze the possibilities and consequences of reducing M Σ in various specially designed systems with such regulation. In article [15], the authors optimize the cooling system of a marine diesel engine by regulating pump performance while keeping the system design unchanged but open to improvement. Article [16] addresses the enhancement of a cooling system by regulating ICC consumption based on the main engine mode, suggesting the replacement of traditional mechanically driven pumps with electrically driven pumps.…”

Rational designs for cooling systems (CS) of internal combustion engines are formulated in the form of a series of circulation circuits. The engine is integrated into a circuit with the highest and unregulated flow of internal circuit coolant (ICC). All heat exchangers are placed in circulation circuits with relatively reduced and adjustable ICC flow rates. While the circuits are usually interconnected, they can also be designed to operate independently. This CS scheme enables the achievement of the minimum possible value of the sum of masses of exchanger cores, denoted as MΣ. The reduction in MΣ is achieved through the regulation of ICC flow in a closed circulation loop involving two heat exchangers. The variations in MΣ based on the circuit parameters have been thoroughly investigated. The reduction in MΣ can also be applicable to more intricate systems. A decrease in MΣ, under identical initial CS parameters, may occur in different magnitudes, depending on the specific features of the CS scheme and the operating conditions of the heat exchangers within it. Cooling systems, constructed with the same initial parameters and comprising multiple circulation circuits that meet all criteria for rational design, may exhibit diverse configurations. Examples of such systems are explored, and the minimum values of MΣ are calculated for each. It has been determined that the disparity in the minimum values of MΣ for such systems, while maintaining equal efficiency, can exceed 30%. The selection of the optimal CS scheme is contingent not only on achieving the minimum possible value of MΣ but also on various other factors.

“…In this way, the aim is to avoid high temperatures, which can cause detonation problems or require engine protection strategies, and low temperatures, which result in higher lubricant viscosity and increased losses due to internal friction [2]. Hence, the vehicle's cooling system must consider its role in critical situations where additional heat could cause localized heating in specific components, resulting in material damage [3]. This issue mainly occurs under full engine load conditions and can be mitigated by circulating coolant at high speeds.…”

“…However, outside these conditions, the system tends to be oversized, leading to high hydraulic losses when under partial load. As a result, cooling systems have undergone numerous improvements to increase cooling capacity to compensate for the engine's thermal rejection [2][3][4]. However, this increase is associated with high energy consumption [3].…”

This study aims to enhance energy efficiency by reducing parasitic losses in the engine cooling system through a new drive strategy involving a two-stage water pump and a variable electro-fan. The fuel consumption gain analysis focused on a vehicle with average characteristics typical of 1.0L hatchbacks in the Brazilian market and urban driving conditions. The methodology implemented aims to minimize power absorbed by the forced water circulation and thermal rejection, thereby reducing parasitic losses, particularly during low-speed urban driving, without causing air-side heat exchanger saturation. The results show a potential decrease of up to 80% in power absorbed by the cooling system, leading to an estimated fuel consumption saving of approximately 1.4% during urban driving cycles.
