Improvement in engine thermal management by changing coolant and oil mass

Editorial: New developments in vehicle thermal management

“…The use of thermal storage is more than an option in the optimization of a so-complex cooling system. It can be used in thermal engines to store the excess energy when the vehicle is running to use it during the warm-up phase, accelerating the heating of the engine or the lubricating oil and reducing fuel consumption and pollutants emissions due to quenching phenomena, low combustion efficiencies and catalyst light-off during the cold phase (Broatch et al, 2022;Vittorini et al, 2022). It can also be helpful in hybrid and electric vehicles to have a reliable thermal source for critical conditions.…”

Model Parameterized Assessment of a Thermal Storage Unit for Engine Oil Warm-up Improvement

“…An extensive literature deals with engine thermal management as a promising option for obtaining reduced emissions and lower fuel consumption via a faster thermal stabilization of the engine [10,11]. Wide margins for enhanced engine performance are associated with a shorter warm up time of the lubricant oil [12,13,14]: a higher temperature of the lubricant is associated with lower viscosity and higher mechanical and organic efficiencies due to lower friction mean effective pressure (FMEP), particularly during engine cold states, when both the power unit and the aftertreatment line provide poor performance [15,16]. In normal conditions, the lube oil heats up by direct contact with metallic parts of the engine.…”
