Question

The intake manifold on a fuel-injected engine contains passages called blank to route the fuel mixture to each cylinder.

A) Injectors
B) Throttle bodies
C) Valves
D) Runners

Answer 1

The intake manifold passages on a fuel-injected engine are called runners, which distribute the fuel-air mixture to each cylinder. Option D is correct.

Step-by-step explanation:

The intake manifold on a fuel-injected engine contains passages called runners to route the fuel mixture to each cylinder. The correct answer to the question is D) Runners. These intake manifold runners ensure that the fuel and air mixture is delivered evenly and efficiently to each engine cylinder for combustion.

This system optimizes engine performance, improves fuel efficiency, and aids in reducing emissions. Other components like injectors, throttle bodies, and valves play different roles in the engine.

Injectors are responsible for spraying fuel into the engine, a throttle body regulates the air entering the engine, and valves control the entry and exit of the fuel-air mixture and exhaust gases in the engine cylinders.

The correct answer is D) Runners. The intake manifold on a fuel-injected engine contains passages called runners to route the fuel mixture to each cylinder.
