Basic knowledge about inejctor nozzle

Fuel injector nozzles, sometimes better known as fuel injector valves, are present in all electronically injected engines. These are responsible for the metering, or "injection" as some experts prefer to say, the injection of a certain amount of fuel into the combustion chamber. And, the better the dosage is controlled, the more efficient the vehicle is in terms of yield, performance and economy.

But after all, what is an injector nozzle sleeve?
A sleeve, also known as a "nozzle cap" in this regard, is nothing more than a component that helps seal the injector nozzle from leaks that could affect operation.

Or, to sum it up in one word that sums it up: precision. This is because the assembly perfects the alignment between the nozzle and its housing, allowing heat exchange across the cylinder head.

And, to guarantee better resistance at higher temperatures, the sleeves are made of copper or steel. These two materials are recommended to ensure temperature control of the injector.

How to identify the measures of the nozzle sleeve?
