Fuel injector measurement

fuel injector

With the continuous improvement of vehicle fuel emission standards, the requirements for the tolerance range of components such as fuel injectors are becoming increasingly strict. Components with stricter tolerance requirements require measuring instruments with higher tolerance. To achieve high-precision measurement of fuel common rail components, it is necessary to have sub micron roundness measuring instruments and high-precision, low-noise surface roughness measuring instruments.

If the measurement of roundness and runout on the surface of the injector seat can achieve sub micron level accuracy, you can confidently control the strict process required for producing injectors.

Regardless of whether the component is radial, angled, or straight, Taylor Hobson series surface measuring instruments can achieve * * analysis of its shape and surface roughness through a single measurement.

With the continuous improvement of vehicle fuel emission standards, the requirements for the tolerance range of geometric shape and surface roughness of fuel injectors and related components are becoming increasingly strict. The concentricity between the valve pin and the base surface of the valve body relative to their respective axes is crucial. For example, the high-precision fit between the valve pin shaft and the valve body requires the cylindricity of the shaft to be critical, and the concentricity of the base surface of the shaft relative to the shaft body is equally important. If any error occurs in either the cylindricity or concentricity mentioned above, it will result in the valve pin not fitting correctly with the valve body, leading to fuel control imbalance and improper flow rate. To prevent such situations, high-precision roundness measurement systems (such as TR395 roundness measurement system) must be used for measurement. The TR395 roundness measurement system has high-precision benchmarks, ultra high precision position control functions, and automatic centering accuracy of up to 0.2 µ m, making it one of the most accurate measurement systems.
