ENGINE COOLING TYPE EXPLAINED

ENGINE COOLING TYPE EXPLAINED:

• AIR-COOLED ENGINE
• OIL COOLED ENGINE
• LIQUID-COOLED ENGINE 
• OIL COOLED ENGINE (SUZUKI TECHNOLOGY)

Air Cooled Engine:

Air-cooled engines are the technology we used to see on our daily commuter /traditional bikes. Most of the bikes use air as a medium to cool the engine. An air-cooled engine, the engine was constructed like there were so many fins running on the Engine block and engine head. These things make the air pass through the engine and efficiently remove the heat from the engine while the bike is on the run. Advantages considered these engines are easy to maintain, have no complex engine structure, maintenance of the engine is low. Disadvantages maybe it won't suit for high revving engine. Air Cooling system is not best in summer times it won't lose heat. It reduces the performance of the engine oil. If you push harder and travel a lot we do not recommend this to you because it leads to engine failure/engine seize

Example for Air-cooled engine: See YAMAHA FZ for an air-cooled engine

Oil Cooled Engine:

Simply we can say this is the air-cooled engine with a small radiator connected to the engine. Oil cooled engines pass the engine oil to the radiator and heat transfer happens then the oil comes back to the engine with optimized temperature this helps the engine to avoid overheating. This is one of the cost-effective methods which gives better results than an air-cooled engine.

Example for Air-cooled engine: FZ25

3. Liquid-cooled Engines:

Liquid cooling engines are the most efficient cooling technology among the three. It supports high revving engines from lower CC to liter-class segment. It has a liquid coolant, forced pump, radiator, and a fan for cooling. Those fans and pumps will be controlled by ECU and thermostat, So that whenever the heat is produced by the engine the ECU commands to run its accessories to keep the engine clean.
Advantages maybe it supports all kinds of bikes, keep the performance on peak all the time, reduced sound because of the cooling tank and only disadvantages here is this is very expensive because of its expensive design. Needs attention and coolant also to be refilled on certain KMs it might vary depending on the bike and its category.

Example for Air-cooled engine : R15 series

4. OIL COOLED ENGINE (SUZUKI TECHNOLOGY):

Suzuki went one step ahead and they made Suzuki oil cooling system (SOCS) – The oil cooling system in the engine was first introduced by Suzuki to the world by using technologies derived from MotoGP such as weight-reduction and friction-reduction technologies. This technology also offers a refined acceleration that feels strong and linear. GIXXER 250 engine provides high output, compactness, low fuel consumption, high durability, and ease of maintenance. Better than air-cooled ones but not the best with the liquid-cooled option concerning efficiency.

Example for Air-cooled engine : Suzuki Gixxer 250cc
