How does a port injection work?

Answer 1

Port injection is a method of fuel delivery in internal combustion engines where fuel is injected into the intake manifold, just before the intake valves. This allows for better mixing of the air and fuel, promoting more efficient combustion. The injection system is typically controlled by an electronic control unit (ECU), which regulates the timing and amount of fuel injected based on engine conditions. This method is commonly used in gasoline engines to enhance performance and reduce emissions.
