What component is used by a 2 stroke engine to pressurize the air in the airbox?

The component used by a 2-stroke engine to pressurize the air in the airbox is an external blower. In a 2-stroke engine, the air-fuel mixture must be cycled quickly and efficiently to ensure optimal performance. An external blower helps facilitate this process by forcing air into the engine's airbox, allowing for better combustion and improved power output.

The external blower enhances the volumetric efficiency of the engine by ensuring that a sufficient amount of air is present for mixing with fuel. This is especially important as 2-stroke engines typically do not have a dedicated exhaust stroke, meaning they rely on effective scavenging of exhaust gases and replenishing the combustion chamber with fresh air and fuel. The use of an external blower allows for increased pressure in the airbox, helping the engine to achieve higher power and efficiency levels.

In contrast, an internal compressor primarily serves different applications and is not typically used in the context of 2-stroke engines in the same manner. A fuel injector's function is solely related to delivering fuel into the combustion chamber rather than pressurizing air, and a mechanical vacuum pump is used for creating vacuum pressure for various accessories but does not pressurize the airbox for combustion purposes. Thus, the
