  • Determine appropriate equipment for minimum work requirements in an agricultural or horticultural workplace.

How Do Engines Not Overheat?

When an engine is operating it produces a significant amount of heat due to the burning process in the combustion chamber. To prevent damage to the engine it is necessary to keep the engine at a correct temperature. Operating an engine at overly high temperatures causes structural damage to engine components, and overly cool operating temperatures mean the fuel will not vaporise properly. The two main methods for cooling engines are air cooling and water cooling.

Air cooling is mainly used in small engines (single cylinder) or for machinery like potato harvesters and elevators. A blast of air is directed on the cylinder and cylinder head, both of which are finned (see diagram below). These fins increase the surface area of the cylinder and provide a larger surface area through which the heat can spread. Air cooled systems are simple and reliable, but are less efficient than water cooled systems as air has a lower heat capacity, so more air is needed to produce the same effect as water. Over-heating can occur if the fins become blocked with dirt, as this reduces the surface area to be cooled.



Water cooling is more effective for use in multi-cylinder engines. The engine cylinders are completely surrounded with a water jacket. The water extends to the cylinder head where there is an outlet to the radiator. There is another outlet at the bottom of the radiator connecting back to the water jacket surrounding the cylinders. Water flows around this system. The radiator is composed of a head tank and a bottom tank. Between these there are a lot of thin tubes and metal plates that greatly increase the surface area to be cooled. This is the core of the radiator. Behind the radiator core there is a fan that operates via a pulley system connected to the crank shaft of the engine. This fan blows cool air onto the radiator. The cooled air circulates back through the engine.

WHO IS THIS COURSE GOING TO BENEFIT?

Anyone who works with machinery on farms, in gardens, or in construction; can benefit from this course. You will even find an application with your car, or any other mechanised equipment around the home.

Machines are such an integral part of our daily lives now that most people take them for granted; and even those who work with machines often don't really understand enough about the machines they work with. If you have not studied mechanical engineering before, this course can change the way you look at engines (both petrol and electric, and the machines they power.

When you understand machinery better, you can make better decisions about where and how you use them; and most importantly maintenance and safety issues associated with machinery.
