Special Issue Information

Dear Colleagues,

With regard to all aspects of internal combustion engines (ICEs) and related technologies, including the most recent studies and advancements affecting the automotive, railroad, marine, and aerospace industries as well as stationary power generation engines, the current Special Issue is meant to be a leading resource for long-term reference information on cutting-edge technological developments and strategic evaluations of future ICE progress. Furthermore, exhaust emissions of ICEs are a major concern. Ongoing efforts to develop more environmentally friendly engines and vehicles are focused on the reduction of exhaust emission standards and after-treatment exhaust strategies. The strong need to eliminate fossil fuel consumption also creates new difficulties for the development of ICEs. On the other hand, advances in engine design and technology are constantly needed due to the continuous evolution of road transportation and the rise in end-user demands for vehicles that are more comfortable, robust, dependable, and fuel-efficient. In many applications, there is no substitute for these advancements. It still seems unlikely that the ICE will be replaced by a new but equally effective source of propulsion, despite several attempts. As a result, intensive research into ICE advancements must continue, and the findings must be made publicly available.

All aspiring authors are encouraged to submit original research papers. All manuscripts will go through an assessment process by reviewers with experience and reputation.

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. Full article
