Can a vehicle have carburetor and also fuel injection?

In general, a vehicle cannot have both a carburetor and fuel injection simultaneously. A carburetor and fuel injection are two different fuel delivery systems used in internal combustion engines. Here's why:

1. Carburetor: A carburetor is a mechanical device that mixes air and fuel before it enters the engine. It relies on the Venturi effect to create suction and draw fuel from the fuel bowl. The fuel is then mixed with air and flows into the engine's intake manifold.

2. Fuel Injection: Fuel injection is a more modern fuel delivery system that uses electronically controlled injectors to spray fuel directly into the engine's intake manifold (in port injection) or directly into the combustion chamber (direct injection). The amount of fuel injected is precisely controlled by the engine control unit (ECU).

Having both a carburetor and fuel injection in the same vehicle would be redundant because both systems serve the same purpose of mixing fuel with air and delivering it to the engine. Additionally, the presence of both systems would introduce unnecessary complexity, potential for fuel delivery conflicts, and potential issues with air-fuel mixture control, potentially causing poor engine performance, increased fuel consumption, and emissions problems.

Therefore, it is generally not practical or effective to have both a carburetor and fuel injection in the same vehicle.
