An injector is a jet pump designed to pump liquid or gas. Its principle of operation: fuel is injected under pressure, while injection can be single-point or distribution. You can even install the injector in your mini-car workshop - in the garage.
Necessary
- - sealing gaskets;
- - engine cover;
- - pulley with teeth for the crankshaft position sensor;
- - drill;
- - temperature sensor;
- - receiver;
- - throttle position sensor;
- - idle speed regulator;
- - plugs;
- - injector;
- - crankshaft position sensor;
- - tubes;
- - wires;
- - tools.
Instructions
Step 1
Drain the coolant to a level below the cylinder head. After that, twist the carburetor, exhaust and intake manifolds, ignition coil, distributor and switch. If forced airflow is installed in the car, then it must also be removed (later forced airflow will be replaced with electric air).
Step 2
Remove the KB pulley and replace it with a new one with teeth for the crankshaft position sensor. Unscrew the front cover of the motor and replace it with a cover that has a drain for the crankshaft position controller. Replace all gaskets at the same time.
Step 3
Remove the tee from the cylinder head, inspect it and find an outflow on it (the coolant temperature sensor will be installed here). Drill and thread a hole for the temperature controller. Then screw the tee to the cylinder head and also connect the sensor with the O-ring.
Step 4
Slide the manifold gaskets, intake pipes and the manifold over the intake and exhaust ports of the cylinder head. If a ramp with nozzles is not installed at the inlet, screw it on by inserting the nozzles first. Then install the receiver and secure it.
Step 5
Complete the throttle assembly with a throttle position sensor and an idle speed regulator. Then attach the choke assembly to the receiver by placing a gasket between them.
Step 6
Install plugs instead of distributor and fuel pump. Following this, install the fine injection filter (this unit must be installed between the fuel line and the gasoline inlet pipe).
Step 7
When installing the injector, a second fuel line is thrown through, which is intended for the return. Such a line can be represented by either a short pipe running through the trunk of a car, or a long pipe running along the bottom, from which a straight hose goes to the tank. The fuel pipe can be screwed in or soldered (the main thing is to well seal the place of contact of the pipe with the tank).
Step 8
On the outer part of the wheel arch, located near the gas tank, install the bracket for attaching the gas pump and the unit itself. Next, connect the hoses: connect the pipe from the intake to the fuel pump, and the hose from the fuel pump to the supply line.
Step 9
Connect the wiring. Then test the operation of the car with the injector.
