Toyota Camry Fuel Injectors

A Toyota fuel injector setup is an important component of your Camry sedan. Your vehicle needs a mix of gasoline and oxygen to ignite and power your vehicle. It is the job of the fuel injector to supply the gasoline when needed and to regulate the amount of fuel and oxygen as necessary.

How does a fuel injector work?

Every Toyota Camry uses an internal combustion process to power itself. The two ingredients necessary to this process are oxygen and gasoline. It is important that a precise ratio of gasoline and oxygen is used in your Camry as too little fuel will not allow the vehicle to start and too much fuel will result in excess.

The role of the fuel injector is to ensure the appropriate amount of gasoline is mixed with the oxygen to allow for combustion. A fuel injector is little more than a valve that opens and closes to supply the engine with a stream of pressurized fuel. A fuel injector has electronic automatic control and can open and close multiple times in a second to provide fuel. Each time the Toyota fuel injector opens, gasoline is sprayed through the nozzle, delivering a fine mist into the intake manifold. The more fuel your car needs, the longer the valve stays open. This is known as pulse width.

How long do Toyota fuel injectors last?

The life span of a Toyota fuel injector is intended by the manufacturer to be extensive. In general, fuel injectors should last one billion engine cycles. For most Toyotas, that is longer than the lifetime of the auto itself.

What are the different types of fuel injectors?
  • Single-point injection: A common system, single-point injection replaced traditional carburetors for several reasons, including that they are easier to service. They include a single nozzle connected to the manifold.
  • Multi-point injection: More advanced than single point, multi-point dedicates a nozzle to each cylinder in the engine. Multi-point is more efficient than single-point given the close placement near the intake port.
  • Sequential systems: Sequential models are similar to multi-point in that they have a nozzle for each port, but while all multi-point nozzles fire at the same time, sequential options activate each nozzle only when that specific port needs additional gasoline.
  • Direct injection: More common in diesel trucks, the direct method involves pumping gasoline directly into the combustion chambers on its own.
