Electric Trucks offer one of the most promising alternatives to vehicles in the field of transport of goods. In battery electric trucks, heat is generated by components present in the electric truck such as battery of the electric vehicle, electric drive system, Endurance Brake System etc. Generally, in the battery electric vehicle, the thermal management system includes two coolant tanks. The first coolant tank performs thermal management for the battery and e-Drive components which can heat up to 600C and the second coolant tank performs thermal management for the endurance braking component which heat up to ~950C. Since Endurance Braking & HPR is a critical component and operates at high temperatures, it has a separate coolant tank. However, in the conventional thermal management systems, the second coolant tank is used less than 5% in entire lifetime of the vehicle.

This research paper investigates the transformative potential of Hydrogen Internal Combustion Engine (H2 ICE) technology in the field of automotive thermal management, with a particular emphasis on its significant implications for truck radiator and intercooler systems. As the automobile industry works to shift to more sustainable and environmentally friendly solutions, hydrogen-powered vehicles provide a viable alternative to their conventional fossil fuel-powered counterparts. The study investigates the unique thermal properties of H2 ICE technology, the modifications required in H2 ICE technology due to specific requirements of air in the combustion, and changes in auxiliary components of the engine, where heating or cooling is required. Based on these changes, assess their impact on radiator and intercooler systems, which are critical components in maintaining the thermal equilibrium of internal combustion engines.

The world over has resulted in severe pollution problems.They are classified as air and noise pollution.Air pollution is caused by to dispersion of emittents from engine exhaust to the atmosphere at different concentration levels. Similarly,the emission of unwanted sound from engine structure, intake and exhaust is the principal source of noise pollution.

The present study develops and analyses a novel thermal management system that utilizes a serpentine cooling plate with fluid flow channels to regulate the temperature of cylindrical lithium-ion batteries in an electric vehicle battery module. The research investigates the impact of many variables affecting the cooling efficiency during discharge processes, including C-rate, number of cooling channels in the cooling plate, inlet fluid velocity and aluminium nanoparticle concentration in the fluid. The study includes 49 lithium-ion batteries with a capacity of 4.9 Ah each using NMC chemistry and a form factor of 21700 connected in series and parallel. A coolant made of water-glycol combination in 70:30 ratio is considered to disperse the thermal energy generated in the batteries. With the increase in the number of cooling channels, the maximum temperature of the batteries is reduced significantly.

This research study investigates the influence of undercover design on three critical aspects of vehicle performance: water entering into air intake filter, Aerodynamic performance, thermal performance on vehicle engine room components (Condenser, Radiator and Air Intake System). Undercover serves the purpose of protecting Engine, underhood components and also improves aerodynamics of the vehicle. Through CFD simulations, various undercover design configurations: Full Undercover, no undercover and half undercover cases are evaluated to assess their effectiveness in mitigating the water ingress into the air intake system. Additionally, we explore the implications of these design alterations on the thermal performance and aerodynamic drag.

Climate across India varies from extreme Cold to extreme hot. As an objective to improve comfort to drivers during summer, it is mandate by Indian Government to introduce Air Conditioning in Trucks from June 2025. Air Conditioning system includes Evaporator, compressor, Condenser and expansion units. Condenser needs continuous air flow to reject the absorbed heat from driver cabin to surrounding air. This is possible by directing air through condenser by an external fan. For this condenser is remotely mounted with an electric driven fan or directly to the radiator-fan system. In this paper a case study is presented where Cooling system of a Non AC Intermediate Commercial Truck is modified for Air Conditioning application. Condenser is mounted on the radiator and the additional heat load is managed by a minor change in the system. Fan is operated based on coolant temperature and with additional controls for Air Conditioning. Simulations are done in a Thermal management software “KULI”.

In recent times, indoor air quality has become an important concern as it affects people's health and comfort. According to WHO report, air pollution causes 7 million deaths every year. PM2.5 has been identified as a key pollutant which impacts human health causing diseases like stroke, heart diseases, breathing issues, cancer and so on. In today's time, we travel by personal vehicle every day, commuting for hours. It is an extension to our homes. Unfortunately, due to frequent door and windows opening, the cabin air gets exposed to outside pollution, and we end up breathing pollutants. To mitigate the problem, air purifiers are added in the automobile. As people are becoming more aware and conscious about good air quality, there is a growing demand for cabin interior air quality solutions for automobiles. A popular approach is to add an air purifier inside cars like ones being used in our homes to bring down the PM2.5 levels.

Cooling module is used in vehicles for engine and Cabin cooling heat exchange with ambient. Cooling module generates flow induced noise due to cooling fan. Cooling module fan noise prediction at CAE level at vehicle level is not available in literature. Many researchers have done fan noise simulation at component level but to it is important to predict vehicle level noise when fan is mounted on a vehicle. Such simulations are transient and complex due to computational cost. Current paper discusses detailed methodology for component and vehicle level CAE simulation. Results of both scenarios are compared with experiments and correlation is established. Component and vehicle level noise simulation is carried out LBM (Lattice Boltzman) based software and tests were conducted in semi anechoic chamber. This paper also demonstrates test and simulation setup used for component and vehicle level acoustics CFD analysis.

Proton exchange membrane (PEM) fuel cells are one potential green energy option for fuel cells, which are becoming more and more popular in the energy production industry. Despite the fact that it continues to draw a lot of interest, many obstacles, such as enhancing performance, boosting durability and reducing cost are impeding the PEM fuel cell's commercialization. The performance of the fuel cell is affected by air/hydrogen feed and thus there is a need to regulate the supply manifold pressure at the cathode side of the fuel cell. A substantial amount of power is used when operating at maximum load, and fuel cells may experience oxygen starvation due to inadequate air. Maintaining a quick and adequate air concentration in the fuel cell cathode is essential to avoiding oxygen starvation and maximizing durability.

Hydrogen-powered mobility is believed to be crucial in the future, as hydrogen constitutes a promising solution to make up for the non-programmable character of the renewable energy sources. In this context, the hydrogen-fueled internal combustion engine represents one of the suitable technical solution for the future sustainable mobility. In a short-term perspective, the development of the green hydrogen production capability and distribution infrastructure do not allow a substantial penetration of pure hydrogen IC engines. For this reason, natural gas – hydrogen blends can represent a first significant step towards decarbonization, also determining a trigger effect on the hydrogen market development. The present paper is focused on the analysis of the combustion and performance characteristics of a production PFI natural gas engine, run on blends with 15% in volume of hydrogen (HCNG).

The global push to minimize carbon emissions and the imposition of more rigorous regulations on emissions are driving an increased exploration of cleaner powertrains for transportation. Hydrogen fuel applications in internal combustion engines are gaining prominence due to their zero carbon emissions and favorable combustion characteristics, particularly in terms of thermal efficiency. However, conventional Spark-Ignition (SI) engines are facing challenges in meeting performance expectations while complying with strict pollutant-emission regulations. These challenges arise from the engine's difficulty in handling advanced combustion strategies, such as lean mixtures, attributed to factors like low ignition energy and abnormal combustion events. To address these issues, the Barrier Discharge Igniter (BDI) stands out for its capability to generate non-equilibrium Low-Temperature Plasma (LTP), a strong promoter of ignition through kinetic, thermal, and transport effects.

In a context of growing concern for vehicle-related CO2 and pollutant emissions, non-conventional fuels like methanol (CH3OH) represent a valid alternative to fossil fuels to decarbonize the transport sector in a reasonable time. This is mainly due to its lower carbon content, compared to conventional gasoline and diesel. Moreover, methanol can be obtained either from biomass or CO2 capture from the atmosphere, which makes the latter a renewable fuel. Given the possibility of being stored in liquid phase at standard temperature and pressure (STP), methanol is very suitable for Light Duty Vehicles (LDVs), in which the need to contain fuel tank dimensions is relevant. Regarding the deployment of methanol as a fuel, it is not very challenging, as it can be adopted in current production Internal Combustion Engines (ICEs) either in pure form or in blend with other fuels without any significant modifications.
