FAQ - Microball answers all your questions:
What is the difference between an injector nozzle
and an injection pump?
The main difference between an injector nozzle and an injection
pump lies in their function within the fuel system: The injection pump
controls the fuel quantity and the required pressure to deliver the fuel
to the injector nozzle. It doses and pumps the fuel precisely to provide
the right amount at the right time.
The injector nozzle, on the other hand, is the component that atomizes
the fuel finely and injects it directly into the combustion chamber.
It controls the exact distribution of the fuel-air mixture for optimal
combustion. In short: The pump delivers and pressurizes the fuel,
the nozzle distributes and atomizes it in the engine.
How does an injector nozzle work?
An injector nozzle controls the precise supply of fuel to the combustion
engine. It doses the fuel under high pressure, atomizes it into a fine
mist, and distributes it in the combustion chamber to ensure optimal
combustion. The integrated ball in the valve ensures quick and tight
closing, preventing backflow and precisely regulating the fuel supply.
Thus, the injector nozzle significantly contributes to the efficiency and
performance of the engine.
Balls for Injection Nozzles and Injection Pumps
Reliable Injection Technology Thanks to
High-Quality Balls
Balls play a central role in the injection technology of combustion engines and contribute significantly to the precise dosing of fuel. Gasoline injection, one of the most important methods for generating an ignitable gasoline-air mixture, is carried out either via single-point injection — where one injection nozzle supplies all cylinders — or via multi-point injection, where each cylinder is assigned its own injection nozzle at the intake valve.
Injection pumps ensure the precise delivery of fuel quantity per stroke and generate the required pressure. Special ball valves are often integrated into the injection nozzles, such as in diesel engines with common-rail systems, which precisely control the fuel flow. The quality of the balls used is crucial for the reliability, functionality, and long service life of the injection system.
microball GmbH offers injection balls in various materials and designs that meet the high demands of combustion engines and ensure optimal performance.
Ceramic Balls for Injection Nozzles
and Injection Pumps
Ceramic balls are used in injection nozzles and injection pumps due to their outstanding wear resistance and chemical stability. They feature high hardness, low weight, and excellent corrosion resistance against fuels. These properties ensure precise and reliable fuel dosing while significantly extending the service life
of the components.
Chrome Steel Balls for Injection
Nozzles and Injection Pumps
Hardened balls made of high-quality bearing steel are particularly
well suited for use in injection nozzles. They offer an optimal
combination of high wear resistance and durable corrosion
resistance against fuels. As a result, these balls ensure reliable
performance and a long service life within injection systems.
