“…There are many sources of literature that focus on research on internal combustion vehicles. The authors of the work [25] analyzed the assessment of the impact of the temperature management strategy on engine warm-up in modern spark engines. The article presents techniques such as thermal insulation, the use of thermoactive pumps or cooling system control in order to assess the impact of these strategies on engine warm-up time, its efficiency, fuel consumption and exhaust emissions.…”

The article analyzes and evaluates costs, transport time and CO2 emissions by selected vans. The research was carried out on the example of three models of Iveco Daily vehicles powered by: diesel oil, electricity and compressed natural gas (CNG). The result of the research presented in the article is the determination of the operating costs of vehicles powered by various energy sources and the level of CO2 emissions. The comparative analysis was carried out on real data for the established transport task. Vehicles with engines powered by compressed natural gas are characterized by the highest savings in terms of transport costs. As the authors pointed out, this may be due to the fact that this type of engines, despite the low interest of buyers at the moment, may gain much more popularity in the future. On the other hand, in relation to vehicles with electric motors, the cost of transport is the highest, which means that this type of technology is ineffective in relation to long-distance transport.

“…This led to a decrease in specific CO 2 emissions of 0.4 g/km when the flow rate was regulated by the eccentricity of the pump with a direct mechanical drive of the engine and 1.4 g/km when the speed of the pump regulated the flow rate through the electrical drive of the pump. Naderi et al [16] proposed an intelligent control system for a pump with an electric drive based on the load-rotation map obtained from a thermal simulation model of the engine and cooling system. The most significant results of the study were a 44% reduction in the pump's drive power and a 2.0% reduction in fuel consumption.…”

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.

“…Abhishek et al 26 conducted complete system level 3D simulations and validated the system simulation model that flow distribution and pressure drop across different components show good comparison with the hydraulic test data within 7% error band. Naderi et al 27 proposed presenting a smart speed-load sensitive cooling map for better engine thermal management and results showed using the cooling map leads to a significant reduction in coolant flow, which in turn reduces the power consumption of the water pump and size of the radiator. Qin et al 28 investigated the flow inside a cooling water jacket of an in-line six-cylinder diesel engine and gave two structural optimization schemes for improving the velocity uniformity of each cylinder.…”

Reasonable coolant flow distribution and its heat transfer coefficient (HTC) distribution are of great significance to the cooling performance of water-cooled engine. Therefore, the present paper proposes a coolant transport path analysis method aiming at analyzing coolant velocity distribution and optimizing the coolant flow characteristics of water jacket based on Computational Fluid Dynamics (CFD), with particular emphasis on the assessment of coolant flow velocity distributions of high-temperature area of engine head water jacket. First, the coolant flow characteristics of a single-cylinder water jacket is investigated and it is found that coolant velocity of exhaust bridge is less than 1.5 m/s and the HTC distribution of water jacket under three flow conditions of 15 L/min, 25 L/min and 35 L/min have a small area reaching 5000 W/(m2∙K). Some areas have no coolant flow and the mass flowrate distribution of each gasket hole is unreasonable, proving that original water jacket structure has some shortcomings and need to be optimized. Based on coolant transport analysis, an improved design of the single cylinder water jacket is proposed and HTC distribution of improved water jacket meet cooling requirements that HTC in high heat load area are above 5000 W/(m2∙K). The coolant transport path analysis method for optimizing coolant flow characteristics of water jacket proves to be an effective way through successful application and remarkable achievement in the other single-cylinder water jacket and two-cylinder water jacket that coolant flow distribution become more reasonable and coolant velocity of high-temperature areas are bigger than 1.5 m/s.
