What type of fuel injection involves a separate fuel injector for each combustion chamber?

The correct answer is multipoint injection, which involves the use of a separate fuel injector for each combustion chamber in an engine. This setup allows for precise fuel delivery directly into each cylinder, optimizing the air-fuel mixture and improving overall combustion efficiency. By having dedicated injectors, multipoint injection systems can fine-tune the fuel amount and timing according to the specific needs of each cylinder, leading to better performance, reduced emissions, and enhanced fuel economy.

In contrast, single-point injection utilizes a single injector to deliver fuel to all cylinders, which may not provide the same level of efficiency and control as multipoint systems. Direct injection refers to a system where fuel is injected directly into the combustion chamber at high pressure, which can enhance efficiency, but still operates through a different mechanism than multipoint injection where sequential control at the individual cylinder level is emphasized. Carburetion is an older system that mixes air and fuel before it enters the engine, lacking the precision and adaptability of fuel injection systems.
