Question

all of the following engines direct the air fuel mixture into the engine through the intake manifold except?
a. gasoline direct - injection
b. multiport fuel injection
c. throttle body injection
d. carbureted

Explanation:

• Multiport fuel injection: In multiport fuel injection, fuel is injected into the intake manifold near each cylinder's intake valve. The air - fuel mixture then travels through the intake manifold to the cylinders.
• Throttle body injection: In throttle body injection, fuel is injected into the throttle body (which is part of the intake system). The air - fuel mixture then moves through the intake manifold to the cylinders.
• Carbureted: In a carbureted system, the carburetor mixes air and fuel. The air - fuel mixture is then drawn through the intake manifold into the cylinders.
• Gasoline direct - injection: In gasoline direct - injection, fuel is injected directly into the combustion chamber of each cylinder, bypassing the intake manifold.

Answer:

A. Gasoline direct - injection
