The test of aluminium-alloy bearings was performed using a bearing tester and test diesel engines. The bearing materials used for the test are 6% Sn aluminium base alloy and a newly developed 12% Sn aluminium-alloy of granular structure type and temper hardened. The applicability of aluminium-alloy bearings to diesel engines was tested by applying them to the crank pin journal bearings. From the test results, the following conclusions are obtained, 1. The load capacity of aluminium-alloy bearings is far superior to that of white metal and is comparable to that of copper-base Kelmet alloy bearings. 2. Aluminium-alloy bearings still have problems which have to be solved before applying to practical engines. These are; (i) Quality control of lubricating oil...the filtering of the lubricating oil must be done perfectly. (ii) Installation of bearing metals...the bearing metals must be fitted carefully to the bearing housing. (iii) The bearing has to be constructed with good accuracy because initial breaking-in property is so poor.
