The product has five features: 1. High-precision injection: It can accurately control the amount and timing of fuel injection to ensure that the fuel can be optimally supplied under different working conditions of the engine and improve the combustion efficiency. 2. Good atomization performance: The fuel injector assembly and fuel injector can fully atomize the fuel, make the fuel particles smaller and mix with the air more evenly, so as to achieve more adequate combustion, improve power output and reduce fuel consumption. 3. Reliable working stability: In various driving conditions and environments, it can maintain stable working performance, ensure the reliability and stability of engine operation, and reduce the probability of failure. 4. Strong durability: With high-quality materials and advanced manufacturing processes, it has a long service life and can withstand long-term use and frequent duty cycles. 5. Good adaptability: Designed and optimized for the 2019 EU and US RAV4 and 2021 Highlander 2.5L engines, it can be well matched with other systems of the vehicle to ensure the performance of the whole vehicle.
