An air-cooled engine is an internal combustion engine in which cooling and maintaining optimum engine temperature is ensured using flowing air.

In today's article, we will briefly look at the air-cooled engine, its division, as well as the advantages and disadvantages of this engine.

A stoichiometric mixture is a mixture of fuel and air that contains the exact amount of air required for perfect combustion of the fuel. This perfect ratio of fuel and air in the mixture is called the stoichiometric ratio.

This article will shed some light on what a stoichiometric mixture is and how it affects the engine.

An air-fuel ratio is a dimensionless number that expresses the ratio between the actual amount of air in the mixture and the theoretical amount (stoichiometric amount) of air corresponding to the fuel used. The coefficient, named in English as the Air-Fuel Ratio, is denoted by the Greek letter λ (lambda).

The coefficient defined in this way is mainly used in the field of internal combustion engines because it is a necessary parameter for the preparation of the mixture. The air-fuel ratio thus thoroughly expresses the mixture's richness level. Each fuel needs a different amount of air for its perfect combustion.

Scratched car body and other small damage may occur on your car almost daily. The reason for their occurrence can have many causes. Whether these damages are caused by an unfriendly neighbor who doesn't know how to park or just a bounced pebble, these small cosmetic defects can cause a lot of wrinkles and worries for the car owner.

Since tinkering and car bodywork require expert knowledge and many years of experience, we will only focus on repairs to minor car body damage in today's article.

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.
