What kind of fuel injection does a car have?
Some cars have multi-point fuel injection where each cylinder is fed by its own injector. This is complex and can be expensive. 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.
What causes wear and tear on fuel injectors?
Driving a car hard, combined with short start stop journeys, will increase the wear and tear on injectors. Letting the engine cool down, before shutting it off, will increase the lifespan of the injectors. This will also, benefit the rest of the engine too.
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 .
When to replace fuel injector seals and washers?
If the O-ring fitted to the injector is the problem; then replacing this O-ring will usually fix the leak. If the injector body; nozzle or internal components are cracked; then a new or refurbished injector is your only option. Replacement fuel injector seals and washers are cheap and are, fairly easy to install.
What are the different types of fuel injection?
There are two types of fuel injection systems, manifold fuel injection and direct fuel injection systems. The basic manifold fuel injection system consist of a fuel pump, fuel pressure regulator, fuel lines, fuel filter, fuel rail, fuel injectors and the engine control unit or engine management system.
Driving a car hard, combined with short start stop journeys, will increase the wear and tear on injectors. Letting the engine cool down, before shutting it off, will increase the lifespan of the injectors. This will also, benefit the rest of the engine too.
What happens when a fuel injection system leaks?
Fuel Injection Systems: If an intake valve is in the open position that fuel will enter the cylinder where it will leak past the rings and eventually mixed with the engine oil. This can cause severe engine oil thinning which can lead to engine bearing damage, scorched cylinder side walls and in some cases an explosion inside the engine.
How does the fuel injector work in a Ford?
The engine draws in oxygen by way of the air intake and fuel from fuel injection. There must be a balanced mix of air to fuel in order to get an efficient mix. This is regulated through sensors, your Ford’s engine computer, and the injectors. The fuel injectors are electronically controlled by the car’s engine control unit.
