In developing the new 2.0-liter and 2-2-liter diesel engines, the plastic region tightening method was applied to the cylinder head bolts, with the following factors taken into consideration: This paper describes the effects on these factors of bolt form, i.e., thread length, shank diameter and threaded shank, heat treatment after or before thread rolling, and tensile strength.Discussed also are reliable specifications based on the preload, gas pressure, and the load due to thermal expansion of the aluminum alloy cylinder head.
