Elements of system of injection Ford Motorcraft EFI of the DOHC engine
Design and principle of action
In electronic multipoint system of injection Ford Motorcraft EFI the fuel given under constant small pressure goes to four nozzles which inject it on inlet the valve. The amount of the sprayed fuel is regulated by time of opening of nozzles determined by the EEC IV electronic control unit on the basis of the speed 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, the regulator of pressure (6), a collector of nozzles (8) and nozzles (10). The regulator of pressure supports constant pressure for this depression in an inlet collector.
The amount of the fuel given to each cylinder is regulated by time of opening of a nozzle falling on each cycle of operation of the cylinder.
The electronic EEC IV actuation device defines this time on the basis of the following signals:
– the sensor (5) of temperature of the arriving air;
– the sensor of speed of the engine located in the ignition distributor;
– 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 the automatic transmission (in cars with the automatic transmission);
– the sensor of turning on of the compressor of the conditioner (in cars with conditioning).
On the basis of these signals the electronic EEC IV actuation device provides composition of mix of fuel, optimum for these operating conditions of the engine, and air.
Besides it operates the valve of the regulator (11) of idling which corrects idling speed by means of supply of additional air via the pipeline (3). In the course of start of the engine the valve of the regulator of idling is open as much as possible.
In no-load time its opening changes depending on requirement, keeping the constant speed of the engine.
