Fuel Injectors

Overview
Ever increasing demands on vehicle fuel emissions mean tighter tolerances on components such as fuel injector systems, tighter toleranced components require higher accuracy instruments. Sub micron roundness measurement combined with high accuracy and low noise surface finish measurement are essential features for measurement of common rail components.

Automotive Applications - Fuel Injector Measurement

Roundness and run-out of injector seating faces can be measured down to sub micron accuracies with a high degree of confidence helping to control the stringent processes required to produce injectors as detailed in the Talyrond links below.

Whether the component form is radial, angled or straight Taylor Hobson range of surface instruments can measure both form and surface finish in a single pass covering all aspects of analysis as detailed in the Form Talysurf links below.

Form Talysurf Inductive Systems
For accurate measurement of roughness, waviness and form of common rail components.

Form Talysurf PGI Measurement Systems
Provides large gauge range/high resolution roughness,waviness and form measurement on common rail components.

Talyrond 365
For high precision inspection of roundness and cylindrical geometry components.

Talyrond 385
Talyrond 385 is the flagship of the mid-range roundness geometry instruments offering high measurement capacity and fully automated axes.

Talyrond 395
At the heart of the Taylor Hobson range of roundness instruments is the Talyrond 395 this instruments high precision spindle, straightness datums and position control enable measurement of the most exacting components.

The increasing demand on vehicle fuel emissions mean tighter tolerances on both the geometric form and surface finish of the fuel injector system and its associated components. Of critical importance are the concentricity’s of the seating face of both the pin and valve body in relation to their respective axes. For example the valve pin shaft fits with high precision into the valve body, the cylindricity of this shaft is critical as is the concentricity of its seating face to the shaft body, any errors in either would cause the pin to seat incorrectly in the valve body, this would result in bad fuel control and flow rate. To prevent this scenario measurements need to be made on high precision roundness systems such as that of the Talyrond 395. This instrument has high accuracy datums with extremely accurate position control and the ability to automate the centering process to less than 0.2µm making this one of the most accurate measurement systems available.
