“…Demuynck evaluated experimental data obtained in a CFR engine covering a wide range of fuels and engine operation conditions in an attempt to develop a fuel independent heat transfer model for spark ignition engines [261,262,263]. Existing heat flux correlations were shown to reproduce the heat flux trace at constant operating point for methane and methanol.…”

Transportation of people and goods largely relies on the use of fossil hydrocarbons, contributing to global warming and problems with local air quality. There are a number of alternatives to fossil fuels that can avoid a net carbon emission and can also decrease pollutant emissions. However, many have significant difficulty in competing with fossil fuels due to either limited availability, limited energy density, high cost, or a combination of these. Methanol (CH 3 OH) is one of these alternatives, which was demonstrated in large fleet trials during the 1980s and 1990s, and is currently again being introduced in various places and applications. It can be produced from fossil fuels, but also from biomass and from renewable energy sources in carbon capture and utilization schemes. It can be used in pure form or as a blend component, in internal combustion engines (ICEs) or in direct methanol fuel cells (DMFCs). These features added to the fact it is a liquid fuel, making it an efficient way of storing and distributing energy, make it stand out as one of the most attractive scalable alternatives. This review focuses on the use of methanol as a pure fuel or blend component for ICEs. First, we introduce methanol historically, briefly introduce the various methods for its production, and summarize health and safety of using methanol as a fuel. Then, we focus on its use as a fuel for ICEs. The current data on the physical and chemical properties relevant for ICEs are reviewed, highlighting the differences with fuels such as ethanol and gasoline. These are then related to the research reported on the behaviour of methanol and methanol blends in spark ignition and compression ignition engines. Many of the properties of methanol that are significantly different from those of for example gasoline (such as its high heat of vaporization) lead to advantages as well as challenges. Both are extensively discussed. Methanol's performance, in terms of power output, peak and part load efficiency, and emissions formation is summarized, for so-called flex-fuel engines

“…Therefore, how to use more efficient cooling mode to solve the problem of heat dissipation in diesel engine becomes very important. The heat flux density of convective heat transfer can be calculated by Newton cooling formula [21][22][23][24] q = h ( tw -tf ).…”

The study of diesel cooling and heat transfer can improve thermal efficiency and reduce exhaust emissions. The research on the heat transfer characteristics of diesel engine block, the influence of the cooling medium control parameters on the heat transfer characteristics of the cooling system and environmental boundary conditions on the heat transfer characteristics of the diesel engine are elaborated, which as the breakthrough point of the research on the cooling heat transfer of diesel engine. The further development direction is discussed. It is pointed out that the research on the content of the best nanoparticles in the nanofluids, the durability test of the low heat rejection (LHR) diesel engine and the intelligent integrated control of the cooling system of the diesel engine at plateau are the key points of the research on the cooling and heat transfer of the diesel engine in the future.

Desarrollar modelos matemáticos para los motores de generación de energía más confiables que permitan proponer un uso eficiente de los combustibles y aumentar la eficiencia de conversión energética, se ha convertido en uno de los principales objetivos de los trabajos de investigación en el área. Con el fin de estudiar el fenómeno liberación de calor en los cilindros de un motor a gas natural J612 Jenbacher de 2 MW a partir de variables medias disponibles en registros operacionales, se ha propuesto un modelo semifísico a partir de balances de masa, energía, ecuaciones constitutivas y regresiones estadísticas. Los resultados muestran que a partir del modelo propuesto del calor rechazado con un coeficiente de determinación de 0.99, el permiten alcanzar un error relativo máximo de 2% en modo isla y del 4% operando en red para la estimación de la temperatura de los gases a las salidas de los cilindros. Así mismo, el modelo permite determinar la fracción de calor perdido en los cilindros en función de la energía aportada por el gas natural
