• Includes 90 main nozzles and 30 slow guide nozzles
• Suitable for carburetors such as PWK, CVK, PE, Kei, OK, KOS, Poli, etc
• The nozzle specifications cover a wide Ran, meeting the needs of different engines
• Provide multiple options to improve oil line injection accuracy
• Suitable for motorcycles, scooters, and other small power equipment
• Precise fuel injection: The carburetor nozzle is responsible for accurately injecting fuel into the engine's intake duct, ensuring that an appropriate amount of fuel is mixed with air to achieve optimal combustion efficiency and improve engine efficiency and power output.
• Multiple specification adaptation: Different engines and car models use nozzles of different specifications. Choosing the appropriate nozzle size based on the engine displacement and requirements is crucial for optimizing performance.
• Improving fuel economy: Good fuel injection performance can ensure efficient use of fuel, avoid waste, enhance fuel economy, and reduce environmental pollution caused by incomplete combustion.
• High temperature and corrosion-resistant materials: Nozzles are usually made of materials that are resistant to high temperatures and corrosion, ensuring stable operation in high-temperature and high-pressure working environments and extending their service life.
• Easy to clean and maintain: Due to the tendency of carburetor nozzles to accumulate carbon or oil stains, regular inspection and cleaning are necessary steps to maintain smooth engine operation. Cleaning the nozzle can ensure fuel injection accuracy and avoid performance degradation or engine failure.
