Reinforced Durable Structural Design

1. Ultra-precision stainless steel multi-hole nozzle: Uniform fine atomization, anti-clogging, resistant to long-term impact of high-pressure gasoline
2. Double-layer PTFE high-temperature sealing gaskets: Prevent high-pressure fuel leakage under continuous cylinder head high temperature
3. Fast-response electromagnetic valve core: Precise control of injection volume and timing, stable fuel supply under idle and full load conditions
4. Integrated thickened metal housing: Anti-corrosion against gasoline additives and engine bay oil mist, extend service life
5. Complete finished product with built-in reusable sealing rings for direct assembly

Core Functions & Engine Protection Advantages

1. Inject atomized high-pressure gasoline into combustion chamber, optimize air-fuel mixing ratio and improve combustion efficiency
2. Eliminate misfire and idle shaking caused by clogged/leaking injectors, restore original throttle response and power output
3. Reduce incomplete combustion black smoke and abnormal fuel consumption, slow carbon buildup on intake valves and pistons
4. Avoid gasoline dilution of lubricating oil, protect crankshaft bearings, piston rings and turbo assembly from premature wear

Fully Resolve Common Injector Failure Symptoms

• Unstable idle speed, periodic severe engine jitter
• Slow acceleration, weak power for overtaking and climbing
• Sharply increased fuel consumption, black smoke emitted during hard acceleration
• Engine malfunction warning light on dashboard, DME stores injector misfire fault codes
• Cold startup difficulty, prolonged cranking time before ignition
• Gasoline mixes with engine oil, causing abnormal oil burning
