Elements of system of injection of Ford Motorcraft EFI of the DOHC engine
Design and action principle
In electronic multipoint system of injection of Ford Motorcraft EFI the fuel submitted under constant small pressure, goes to four nozzles which inject it on inlet the valve. The amount of sprayed fuel is regulated by time of opening of the nozzles, a defined electronic control unit of EES IV on the basis of number of turns of the engine and size of course of the air consumed by the engine.
The electric fuel pump shipped in a tank, forces constantly fuel through the pipeline to the fuel filter, a regulator of pressure (6), a collector of nozzles (8) and to nozzles (10). The regulator of pressure supports constant pressure for this depression in an inlet collector.
The amount of the fuel submitted to each cylinder, is regulated by time of opening of the nozzle, falling on each cycle of operation of the cylinder.
The EES IV electronic actuation device defines this time on the basis of the following signals:
– the sensor (5) temperatures of arriving air;
– the sensor of number of turns of the engine located in the distributor of ignition;
– the sensor (4) cooling liquids;
– the sensor of provision of the butterfly valve located in a case of a butterfly valve (2);
– the sensor of position of the lever of gear shifting of an automatic transmission (in cars with an automatic transmission);
– the sensor of turning on of the compressor of the conditioner (in cars with conditioning).
On the basis of these signals the EES IV electronic actuation device provides optimum for these operating conditions of the engine structure of a mix of fuel and air.
Besides it operates the valve of a regulator (11) idlings which corrects number of turns of idling by means of supply of additional air via the pipeline (3). In the course of engine start the valve of a regulator of idling is open as much as possible.
In a no-load time its opening changes depending on requirement, holding constant number of turns of the engine.
