Question

which of the following is not a common characteristic of a gdi system?

a. expensive
b. noisy
c. complicated
d. high emissions

Explanation:

Gasoline Direct Injection (GDI) systems are known for their efficiency, which typically leads to lower emissions compared to some other fuel - injection systems. They are often more expensive due to the precision components required for direct injection. The high - pressure fuel delivery and injection process can make them noisier. Also, the design with direct injection into the combustion chamber (as opposed to port - injection) adds to the complexity of the system.

Answer:

d. High emissions
