Question

* port injection system. Define and explained")​

Answer 1

Answer:

here's ur answer dude

Explanation:

In conventional PFI (port fuel injection) gasoline engines (Fig. 7.1), fuel is injected onto intake port surfaces and closed intake valves. Most of the injected fuel evaporates and mixes with the fresh intake air before it flows into the cylinder. This mixture is typically very well mixed before ignition occurs.

hope it helps

Answer 2

Explanation:

In comparison to PEMFC, a baseline port fuel-injection H2ICE converts hydrogen energy to mechanical power at significantly lower peak efficiencies(HyICE) illustrates the progression of advancing H2ICE technologies relative to a baseline port fuel-injection gasoline engine, where gasoline is injected upstream of the intake valve. Because of its greater volume, gaseous hydrogen used in a port fuel-injection engine actually results in a loss of volumetric efficiency, relative to gasoline, and a loss of power.......
