In this research we study the most important properties of the cooling media used in internal combustion engines, the amount of heat that loosed in the environment, and we try to develop the scientific basis for possible recycling of waste heat in the context of attempts that seek to increase the motor efficiency.

The study presents the idea to take advantage of liquid fuel in the engine cooling, which raises the temperature and thus the amount of heat entering the engine and to contribute to, as a result, in terms of improving the economic factors of the engine work.

Research includes a pilot study of the thermal properties of some fuels and oils used in internal combustion engines. This will indicate its location among coolants map and their advantages and disadvantages

The study concentrated on the features of fluids used in cooling circuits, and similar types of suggested kinds of fuel to make a good comparison between them, and then determine the optimal conditions for their respective work that lead to improved engine performance.

Keys: diesel fuel, biodiesel, coolants, cottonseeds oil, internal combustion engines.

يتعرض البحث لدراسة أهم خواص وسائط التبريد المستخدمة في محركات الاحتراق الداخلي وكمية الحرارة التي تطرحها في الوسط المحيط، ووضع الأسس العلمية التدوير ما أمكن من الحرارة المهدورة في إطار المحاولات الساعية إلى زيادة مردود المحرك.
