In the heart of the automobile's power scene, the precision of fuel injectors directly determines engine efficiency and environmental performance. Traditional processing processes face bottlenecks such as insufficient microporous accuracy, heat-affected zone damage, and limited special-shaped hole processing, making it difficult to meet the stricter emission standards of China VIB and the future. Yue Qian Laser uses femtosecond laser technology to bring revolutionary solutions to the manufacturing of automotive fuel injectors.

Three major pain points of traditional technology: restricting the upgrading of internal combustion engines
Accuracy bottlenecks | EDM is difficult to achieve stable < 100μm micropores, large pore size error, and insufficient roundness, resulting in uneven fuel atomization and low combustion efficiency. |
Thermal damage traps | Nanosecond/microsecond laser processing produces recast layers, microcracks and burrs, which become a breeding ground for carbon build-up and shorten the life of the injector by more than 30%. |
Structural limitations | Complex special-shaped holes require multi-process processing, and the cumulative accuracy error is large, which cannot meet the precise control requirements of the new generation engine for precise control of the injection trajectory |

Three core advantages of femtosecond laser: solving industry problems
Micron level Precision control | Precise atomization, green and environmentally friendly With ±1μm positioning and processing accuracy, the nozzle taper deviation is zero, the roundness error is < 1μm, the fuel particle atomization uniformity is increased by 25%, the combustion efficiency is increased by 12%, and the fuel consumption is reduced by 8%. Every drop of fuel is atomized with precision and fully combusted, reducing pollutant emissions at the source. |
Zero thermal damage Cold processing | Say goodbye to carbon deposits and reduce costs Femtosecond ultra-short pulses (10⁻¹⁵ seconds) directly vaporize the material through a "cold ablation" mechanism, completely eliminating recast layers, microcracks and burrs, and the hole wall roughness Ra≤0.4 μm. The carbon adhesion rate is reduced by 90%, and the fuel injector life is extended by 2 times, reducing engine maintenance costs and downtime. |
Complex structure Freeforming | Jet trajectory, precise customization It supports the one-time forming of dozens of special-shaped holes such as oblique holes, inverted cone holes, and rice zigzag holes, and with the five-axis linkage system, the angle and distribution of the porous array can be accurately customized. After the optimization of the injection trajectory and air-fuel ratio, exhaust emissions are reduced by 18%, which can easily meet the stricter emission standards of China VIB and the future. |
