What is the equivalent to an intake manifold in a 2 stroke engine?

In a two-stroke engine, the equivalent to an intake manifold is the air box. The air box serves as the chamber that collects and directs the incoming air-fuel mixture to the combustion chamber. Unlike a four-stroke engine, where an intake manifold is used to manage the flow of air into the engine, a two-stroke engine relies on the air box to facilitate the flow of the mixture directly into the crankcase or cylinder.

As the piston moves down during the intake phase of the cycle, fresh air enters the air box, often aided by the unique design of the engine which utilizes the crankcase pressure to help draw in the air-fuel mixture. This is crucial for the operation of a two-stroke engine, contributing to its efficiency and power output. The air box must be designed to optimize airflow, ensuring that the engine receives the correct mixture of air and fuel for combustion.

The other options—carburetor, throttle body, and fuel injector—play different roles in the fuel management system. The carburetor mixes air with fuel before it enters the combustion chamber, the throttle body controls the amount of air entering the engine, and the fuel injector is responsible for directly injecting fuel into the combustion chamber. However, none of
