COOLING AND LUBRICATING SYSTEMS
The cooling and lubricating systems of the engine really work to-I gether like a team. It might be more accurate if we called the cooling P system a "heat control system". Working with the lubrication system, it carries off excessive heat (cools); but it also keeps the engine at its correct operating temperature (heat control). To get satisfaction and economy from a tractor, this correct temperature must be maintained. Much of the heal of the burning fuel must be quickly absorbed by the cooling system, especially the excessive heat from a cylinder walls, cylinder head, pistons and valves. If this great heat were not quickly carried off, these parts could not function; the oil lubricating them would soon bum. The oil must be kept cool enough to perform its double function of reducing friction and of transmitting heat from the pistons to the cylinder walls and hence to the cooling system. Yet a relatively high tempera-ture-160° F, or more is needed to vaporize the liquid fuel, to get complete combustion and full power, and to prevent unburned fuel from diluting the engine oil. Continual overcooling may be almost as serious, and as costly overheating.III. Ответьте на вопросы:
