Model E71/E72 BMW Spray Hose 61667275175

The BMW X3's water injection hose 61667276500 technology is mainly used in its high-performance models, particularly the M4 and M4 GTS models. Known as the Water Injection System (WIS), the core principle of this technology is that pure water is atomized and mixed with air by means of high-pressure injectors fitted to the intake tracts, cooling the intake manifolds with the heat of vaporization before the fuel is ignited. This technology is particularly effective during acceleration and at high speeds, and can significantly reduce fuel consumption and improve fuel consumption performance by up to 13 percent

Working PrincipleWhen the engine is under high load, the water pump transports the water from the water tank to the water injector, which atomizes the water and sprays it into the intake tract to pre-mix with the air. When the intake valve is opened, what enters the cylinder is no longer just air, but a mixture of air and atomized water. This mixture can reduce the temperature of the oil and gas mixture in the cylinder, thereby improving combustion efficiency, reducing the occurrence of detonation, and increase the compression ratio of the engine, which in turn improves the engine output power and torque!
