MPFI system
In the port injection arrangement, the injectoe is placed on the side of the intake manifold near the intake port. The injector sprays gasoline into the air, inside the intake manifold. The gasoline mixes with the air in the intake manifold near the intake port. This mixture of gasoline and air then passes through the intake valve and enters into the cylinder. Every cylinder is provided with an injector in its intake manifold. If there are six cylinders, there will be six injectors as shown in figure.
