When the points open, the field collapses and voltage is sent to one of the spark plug. Some distributor shafts operate the oil pump. It distributes the coils high voltage to the plugs wires. Secondary Windings consist of several thousand turns of very fine wire, located inside or near the secondary windings. Varies the ignition timing as engine speed, load and other conditions change. Times the spark so that it occurs as the piston nears the TDC on the compression stroke. Operates on various supply voltages Battery Alternator Produces high voltage arcs at the spark plug electrode.ĭistributes spark to each plug in correct sequence.

Advantages of multi point fuel injection system? Multi Point Fuel Injection. The pressure in the intake manifold significantly changes with the engine speed and load. While the control diaphragm and pressure spring controls the outlet valve opening and the amount of fuel that can return. The fuel pressure regulator, connected to the fuel rail by means of an inlet and outlet, directs the flow of the fuel.
MPFI includes a fuel pressure regulator, fuel injectors, cylinders, pressure spring and a control diaphragm. In the simultaneous system, fuel is inserted to all cylinders at the same time, while the sequential system injection is timed to overlap with intake stroke of each cylinder.
In the batched MPFI system fuel is injected to the groups or batches of the cylinders without bringing their intake stroke together. It delivers an exact quantity of fuel in each cylinder at the right time. What is multi point fuel injection MPFI system? The MPFI is a system or method of injecting fuel into internal combustion engine through multi ports situated on intake valve of each cylinder.
