Abstract
Increasing the thermal efficiency of an engine decreases the amount of available thermal energy, making it necessary to optimize the heat distribution between the engine and each device to make effective use of the limited amount of energy. The research described in this article addressed the creation of an integrated system for analyzing the cooling system as a whole to enable more efficient vehicle development. A method to predict time histories of temperature and heat distribution of each part based on vehicle driving patterns has been completed by utilizing 1D analysis in which elements relating to the performance of the vehicle heater system are arranged as parameters. This simulation
method can be also utilized at the planning stage of vehicle development by converting the
parameters into a database. In addition, the method can be also utilized to analyze fuel
consumption in the warm-up process, the results of which can be used to effectively improve
fuel consumption.
