A liquid-cooled engine is a combustion engine that uses a cooling liquid to remove heat from the cooled surfaces, dissipating this heat into the air.

Liquid cooling of the engine is indirect because the liquid is only an intermediary for transferring temperature from the engine to the air. Distilled water or antifreeze is used as a cooling liquid.

A rocket engine is a type of reactive engine that is not affected by the external environment, thanks to the fact that it carries fuel and an oxidizer in its reservoir.

This article will briefly examine how a rocket engine works, its history, and possible types.

A carburetor prepares the mixture for petrol engines that burn liquid fuel and air. This mixture's preparation consists of atomizing the fuel in the air stream.

Almost all spark-ignition engines used a carburetor in the past, but today it is replaced by injection devices.

The task of the engine cooling system is to remove the excess heat generated during the combustion process and transfer it to the individual parts of the engine and into the engine oil.

Engine cooling is, therefore, a critical aspect of maintaining optimal engine performance and extending its lifespan. It protects the engine and components from overheating and ensures a stable engine operating temperature.

A thermostat is a device that controls the flow of coolant liquid in the engine's cooling circuit. Every engine has a certain ideal working temperature that it needs to reach for its optimal operation.

If the engine does not work at its ideal working temperature - it is not optimally warmed up - it leads to higher fuel consumption, worse operation, higher noise, but also greater wear of all engine parts.

Every internal combustion engine needs an optimal temperature for its efficient operation. The cooling system ensures this optimal engine operating temperature, without which the engine would quickly overheat and seize.

There are several ways to cool the engine, but when it comes to liquid cooling, the cooling system logically needs coolant liquid to function properly.
