19 multiple choice 1 point\nwhat is the advantage of port injection over direct injection?\nport injection offers better catalyst heating\nport injection offers better fuel economy\nport injection ensures intake valves are constantly cleaned\nport injection allows for higher boost pressure with lower octane fuel.
Answer
Brief Explanations:
Port injection sprays fuel into the intake port. As the fuel travels through the intake port and valve, it helps clean deposits on the intake valve. Direct injection sprays fuel directly into the combustion chamber, so the intake valve doesn't get cleaned by fuel in the same way as port injection.
Answer:
port injection ensures intake valves are constantly cleaned
