Abstract

PURPOSE: To reduce the resistance of the cylinder block of an engine wherein the flexural rigidity Kc of the crank shaft beared by a main shaft receiver is set at FL2/ 16(1.5W3.0×10-3), by setting the flexural rigidity Kb at (Kc/Kb)(4/L)≥10.
CONSTITUTION: In the cylinder block wherein the flexural rigidity Kc of the crank shaft 5 beared by the main shaft receiver 6 formed in a partition wall 1 of a skirt 3 of the cylinder block is set at FL2/16(1.5W3.0×10-3), the flexural rigidity Kb of the main shaft receiver is set at (Kc/Kb)(4/L)≤10. Thus, when an explosion load F is acted, the deviated position δ of the main shaft receiver 6 can be decreased, the resistance and weight can be reduced, the output performance and performance for fuel cost for the engine can be improved, and noises from the skirt outer wall can be suppressed.
