Internal Combustion Engine Blades

Internal combustion engine blades typically have complex curved shapes to accommodate airflow characteristics. Their profile may be approximately trapezoidal, gradually widening from the inner diameter to the outer diameter and curving inward, with the outlet edge possibly being a convex arc. In internal combustion engines, internal combustion engine blades work by interacting with the airflow, using high-temperature, high-pressure gas to drive the blades to rotate, converting thermal energy into mechanical energy. Cooling fan blades, on the other hand, promote airflow through rotation, dissipating heat for the internal combustion engine.
Internal combustion engine blades are often manufactured using processes such as precision casting, with high requirements for dimensional accuracy. It is necessary to control the blade profile and channel contour to ensure blade performance and the accuracy of fit with other components.
