One of the key factors limiting the widespread adoption of electric trucks for long-haul freight is battery technology. Traditional batteries used in commercial electric vehicles are often not sufficient to power heavy-duty trucks over long distances without frequent recharging. However, advancements in battery chemistry and energy density are making NEV new energy vehicles more viable for such tasks.

At its core, a carburetor engine operates on the principle of mixing air and fuel to create a combustible mixture that powers the engine. The carburetor itself is a mechanical device that regulates this mixture by utilizing the Venturi effect—where air flowing through a narrowing passage creates a drop in pressure, drawing fuel from the float chamber into the airstream. This mixture then enters the combustion chamber of the engine, where it is ignited by the spark plugs, producing the energy necessary to propel the vehicle.
