Fluid Mechanics: The "Venturi Effect" mixing fuel inside your Smart Generator

The EcoFlow Smart Generator (Dual Fuel) is incredibly efficient, but how does it physically pull the exact right amount of gasoline or propane into the engine without using a high-pressure electronic fuel pump? It relies on a principle of fluid mechanics discovered in 1797: the Venturi Effect.

Inside the generator's carburetor, the air intake tube features a specialized "choke point" where the tunnel becomes very narrow. According to Bernoulli’s Principle, when a fluid (or gas, like air) is forced through a restriction, its velocity must increase. As the air speeds up through this narrow neck, its physical pressure drops drastically, creating a localized vacuum.

This vacuum sits directly over the microscopic fuel jets. The low pressure physically sucks the liquid gasoline (or propane gas) up out of the bowl and atomizes it into the rushing air. The faster the engine runs, the faster the air moves, the stronger the vacuum becomes, pulling in exactly the right stoichiometric ratio of fuel! It is pure, mechanical fluid dynamics driving the engine.
