Detailed Description
The invention will be further described with reference to the following detailed description and accompanying drawings.
Example 1:
as shown in fig. 1 to 4, an environmentally friendly aluminum alloy engine case includes a crankcase body 1 and a cylinder block 2. The crankcase body 1 and the cylinder block 2 are integrally formed by casting. The crankcase body 1 and the cylinder block 2 are both made of environment-friendly aluminum alloy materials. One end of the cylinder block 2 is provided with a connection hole 4. The cylinder block 2 is provided with cylinder bores. A wear resistant liner 3 is provided in the cylinder bore.
The wear-resistant bush 3 is cylindrical. The wear-resistant lining 3 consists of an outer ring layer 5 and an inner ring layer 6. The outer ring layer 5 is made of metal and the inner ring layer 6 is made of wear-resistant ceramic.
