5. Mechanical power transmission means are often the cause of vibration.
6. It should be noted that the depth of the cover is very small compared with its diameter, which means that the fuel valves can be made short and light.

9. These bearings are used for both crankpins and main bearings.
10. The speed of both the in-line and vee-form engines is reduced from 720 to 500 rpm when they are used for auxiliary purposes.
