The specific gravity of aluminum is smaller than that of cast iron. Under the premise of meeting the strength requirements, the aluminum cylinder is much lighter. The engine is light, which can have a positive impact on the weight distribution of the vehicle, and the vehicle mass is also lighter. Therefore, at this point, the aluminum cylinder block is dominant.
For the same reason, the specific gravity of aluminum is small, and the structural strength of aluminum per unit volume is lower than that of cast iron, so the volume of aluminum cylinders is usually larger. The cylinder center distance of EA113/EA888 is 88mm, while the bore diameter of the existing version can reach 82.5mm. Excluding the cooling water channel, the cylinder wall is actually quite thin.

Aluminum conducts heat faster, so it has better cooling performance, which can help the engine reduce the probability of abnormal combustion. With the same compression ratio, an aluminum cylinder engine can use lower-grade gasoline than a cast iron cylinder engine. At this point, the aluminum cylinder block is dominant.
