Know the 2 types of engine cooling systems
The engine cooling system in vehicles is a system that functions to keep the engine temperature and temperature in ideal conditions.
Yes. Many car engines currently use engines with an internal combustion system, where the process of generating engine power is produced through the combustion of fuel and air in the engine cylinders.
The continuous combustion process will increase the temperature and working temperature of the engine. Without an engine cooling system, the engine becomes inefficient, wasteful and causes damage to the engine components inside.
Here are 2 types of engine cooling systems that are widely used in vehicles, see the article about 2 types of engine cooling systems below.
1. Air conditioning system
Machines with air cooling systems are machines that use air / wind directly to reduce the heat and working temperature of the engine.
The engine that uses this air cooling system has a design on the engine cylinder and cylinder head that adds cooling fins around the engine body. The engine cooling fins are installed together with the engine cylinder body and become an integral part of the engine.
These cooling fins serve to expand the contact area between the engine and the surrounding air so that the heat release process from the engine can take place more quickly.
Take a look at the image of an air-cooled engine example below
In an engine with an air cooling system, the heat generated from combustion in the engine cylinder partially propagates out through the cooling fins. The heat that propagates to the cooling fins of this engine will then be absorbed by the outside air whose temperature is much lower than the temperature in the cooling fins.
However, the air used to absorb heat from the cooling fins must continue to flow. In addition, the required air flow speed must also be proportional to the engine rotation speed so that the ideal working temperature of the engine can be achieved and cooling can continue optimally.
Therefore, to anticipate overheating when the air flow is reduced (such as when conditions are jammed and moving slowly), some engines have a blower fan installed to maintain the flow of air that flows between the cooling fins.
Here are some of the advantages and disadvantages of machines with air conditioning systems:
Advantages of the air conditioning system engine:
- Has a more compact engine design
- Has a lighter engine weight compared to water-cooled engines
- Easier to maintain
Disadvantages of air conditioning systems:
- The cooling process is influenced by the speed of the vehicle so that it has the potential to overheat when road conditions are jammed.
- Only suitable for use on small capacity machines
Due to its conspicuous shortcomings when used in car engines, engines with air cooling systems are becoming less popular nowadays. Machines with this air conditioning system are more commonly found in old cars from the 1950s to 2000s, such as the VW frog type 1 and type 4, Fiat 126, Honda 1300, Citroen GS and GSA, and others. other.
2. Water cooling system
Machines with a water cooling system are machines that use water / liquid coolant directly to absorb heat and the engine's working temperature. Machines with a water cooling system have a more complicated machine construction compared to machines with an air cooling system.
This is because the parts of the engine cylinder (especially those that produce engine heat) must be covered with cooling water on the outside so that on the outside of the cylinder wall there must be a water jacket (water coat) as a place for coolant to flow and absorb engine heat. Look at the image of an example of a machine with a water cooling system below.
The working principle for machines that use this water cooling system is to utilize the flow of cold water to absorb engine heat. Cooling water that has been used to absorb heat will flow to the radiator components to cool the temperature again. And cold water from the radiator will flow into the engine.
After the water temperature in the radiator cools down, the cooler water will flow back into the engine to absorb heat again and so on.
For more details about how the water cooling system works and the names of its components, you can read it in the following article:
Here are the advantages and disadvantages of machines with a water cooling system
Advantages of machines with water cooling system:
- The process of cooling the engine temperature can take place at any time without being affected by the speed and speed of the vehicle
- The engine reaches the ideal engine working temperature faster
- More efficient fuel consumption
- Can be used on large capacity engines
Disadvantages of machines with a water cooling system:
- Machine construction is more complicated and prone to liquid leakage
- Requires extra care and maintenance of the cooling system
- Requires more components for water cooling system.
Even so, this engine with a water cooling system has the ability and advantages that are able to maintain the durability of the vehicle during use so that the engine with a water cooling system is more widely used in today's cars.
