Technical development trend of fuel injectors
1. Ultra-high pressure injection and precise atomization technology
The pressure limit continues to break through: the pressure of the diesel common rail system has moved from 200MPa to 300-400MPa, and the gasoline direct injection (GDI) pressure has increased from 35MPa to 50-80MPa. For example, the Fengyun T8 Kunpeng super hybrid engine adopts 350Bar ultra-high pressure direct injection technology, and the fuel atomization particle size is reduced to 8 microns (1/10 of a hair), and the combustion efficiency is improved by more than 15%.
Porous and micro-spray hole design: the number of spray holes is increased from 6 holes to 8-12 holes, and the hole diameter is reduced to less than 0.1mm. With ultra-high pressure, "micron-level oil mist" (diameter ≤10μm) is achieved, reducing particulate matter (PM) emissions by more than 50%.
2. Intelligent and adaptive control system
Real-time closed-loop feedback system: Dynamically adjust the injection parameters (oil volume, timing, pressure) through the in-cylinder pressure sensor (500 samples per cycle), knock sensor and AI algorithm. For example, the AI self-learning system of the Fengyun T8 engine can automatically optimize the injection volume according to the working conditions such as plateau hypoxia and oil quality differences, and the thermal efficiency fluctuation is less than 1.5%.
Multiple injection strategy upgrade: From the traditional pre-injection + main injection mode, it has developed into a multi-level control of pre-injection, main injection, post-injection, and secondary post-injection, combined with piezoelectric actuators (response speed 0.1ms) to achieve 7 times/cycle injection, reducing NOx emissions by more than 30%.
3. Material science and manufacturing process innovation
Application of high-performance materials:
Wear-resistant coating: tungsten carbide (WC) coating, multi-layer gradient diamond-like coating (such as Fengyun T8 piston ring) reduces the wear rate by 70%.
High-temperature alloys: Nickel-based super-heat-resistant alloys (such as LaserForm® Ni718) are used for 3D printed fuel injectors, which can withstand high temperatures of 3300°C and increase their lifespan by 5 times.
Soft magnetic stainless steel: Through magnetic property heat treatment control technology, the response speed of the electromagnetic coil is optimized and the coercive force is reduced by 20%.
3D printing technology breakthrough: Bosch of Germany integrates more than 30 parts into a single integral structure, reducing weight by 25% and reducing leakage points by 80%. GE Aviation uses 3D printing to manufacture fuel nozzles, and 14 complex flow channels achieve self-cooling, increasing lifespan by 3 times.
4. Integration and lightweight design
Highly integrated structure: The injector is integrated with the high-pressure pump and sensor (such as the Bosch CRIN3 common rail injector, which is 30% smaller in size), reducing energy loss and improving reliability.
Modular manufacturing: "Functional integration" is achieved through 3D printing, such as directly embedding the cooling channel and pressure sensor channel into the injector body, which increases assembly efficiency by 50%.
5. Intelligent diagnosis and maintenance technology
Precise fault diagnosis:
Ultrasonic cleaning: remove carbon deposits from the spray hole and restore the injection volume to the nominal value ±3%.
Intelligent detection system: Through misfire counter, fuel correction value analysis (short-term correction > ±15% triggers an alarm) and λ value monitoring, the fault location accuracy of ±0.3ms injection time difference is achieved.
Predictive maintenance: Combined with the Internet of Things (IoT) and big data analysis, the cloud algorithm predicts the life of components (such as needle valve wear compensation), and the replacement cycle is warned in advance, reducing downtime by more than 30%.
6. Hybrid system collaborative optimization
Hybrid dedicated injector: Develop low-inertia electromagnetic actuators and wide-range pressure regulation technology for hybrid working conditions (such as frequent start-stop and high-load power generation). For example, the Fengyun T8 engine uses 350Bar direct injection and AI control to heat up by 40℃ in 3 minutes when cold-started at -35℃, and achieve an increase of 80km in the range of plateau areas.
Energy recovery linkage control: Optimize the injection strategy in coordination with the motor, such as reducing the injection volume during the braking energy recovery phase, and improving the vehicle's energy efficiency by 8-12%.
7. Technology upgrade driven by environmental regulations
Ultra-low emission adaptation: Meet the requirements of National VI b, Euro VII and other regulations, through ultra-high pressure atomization (oil droplet diameter ≤ 10μm) and precise oxygen sensor feedback, make particulate matter (PM) emissions <4.5mg/kWh, and reduce nitrogen oxides (NOx) by 50%.
Alternative fuel compatibility: Develop injectors that can adapt to biodiesel and synthetic fuels (e-fuel), and ensure that the combustion efficiency is not lower than that of traditional fuels through aperture optimization and spray shape adjustment.
8. Domestic technological breakthroughs and global competition
The rise of independent technology: Nanyue Electric Control's independently developed electronically controlled high-pressure common rail system (pressure 300MPa) has been used by Weichai, Cummins and other companies, and exported to the Southeast Asian market, breaking the foreign monopoly.
Reconstruction of market structure: It is estimated that by 2030, the domestic injector market will reach 30 billion yuan, and the proportion of domestic high-end products will increase from 35% in 2024 to more than 50%, while the export share will increase to 35% of the global market.
9. Exploration of future technological frontiers
Supercritical fluid injection: Using supercritical fluids such as CO₂ to improve the fuel crushing effect, the oil droplet diameter can be further reduced to less than 5μm, and the combustion efficiency is increased by 10%.
Photon counting imaging technology: Through high-speed cameras and photon counting algorithms, the spray morphology is observed in real time to optimize the airflow distribution in the combustion chamber.
Hydrogen fuel injection system: Develop high-pressure direct injection technology suitable for hydrogen internal combustion engines, and the injection pressure must reach more than 70MPa to ensure uniform mixing of hydrogen and air.
