Do fuel injected engines have distributors?
Do fuel injected engines have distributors?
Most distributors used on electronically fuel injected engines lack vacuum and centrifugal advance units. On such distributors, the timing advance is controlled electronically by the engine computer. Additionally, eliminating vacuum and centrifugal advance results in a simpler and more reliable distributor.
Do fuel injected cars have points?
All modern petrol injection systems use indirect injection. A special pump sends the fuel under pressure from the fuel tank to the engine bay where, still under pressure, it is distributed individually to each cylinder. Some cars have multi-point fuel injection where each cylinder is fed by its own injector.
Do modern engines use distributors?
Many modern cars have no distributor at all. The ignition is triggered by toothed timing wheels spinning with the crankshaft, which is much more accurate than points. Then there are individual coils for each cylinder, fired by the engine management computer. But there is still no distributor.
What does a multi point injected engine have?
Typically though, a multi-point injected engine has one fuel injector per cylinder, an electric fuel pump, a fuel distributor, an airflow sensor, and, in modern engines, an engine control unit.
How does a performance ignition distributor work on a fuel injection engine?
Many distributors used with electronic fuel injection engines do not have vacuum and centrifugal advance mechanisms. On such “chip controlled distributors”, the timing advance is controlled electronically by an engine computer. Timing can be adjusted more accurately based on a wider variety of factors – not just rpms and intake manifold vacuum.
How does a single point fuel injection system work?
It’s more common to have single-point injection where a single injector feeds all the cylinders, or to have one injector to every two cylinders. The injectors through which the fuel is sprayed are screwed, nozzle-first, into either the inlet manifold or the cylinder head and are angled so that the spray of fuel is fired towards the inlet valve .
Where is the distributor cap on a fuel injection engine?
A look at the distributor cap that sits on top of a typical modern distributor with computer controls. Many distributors used with electronic fuel injection engines do not have vacuum and centrifugal advance mechanisms. On such “chip controlled distributors”, the timing advance is controlled electronically by an engine computer.

Where are the points on an ignition distributor?
A set of points and condenser sit on a plate under the cap. The opening and closing of the points, once for each cylinder for each rotation of the rotor, helps create the high energy spark from the ignition coil. The distributor shaft may be driven by a gear on the crankshaft or camshaft.
