Improvement of a lightweight aluminium cylinder block design using finite element stress analysis
A SAE technical paper (2012-01-0406) has discussed about the design and manufacturing method of a lightweight cylinder block made from cast iron. In applying the features discussed in the paper to an aluminium cylinder block with a different displacement, certain modifications need to be made to t...

description |
A SAE technical paper (2012-01-0406) has discussed about the design and manufacturing method of a
lightweight cylinder block made from cast iron. In applying the features discussed in the paper to an aluminium
cylinder block with a different displacement, certain modifications need to be made to the previously proposed
design. In addition to that and following the ongoing trend, many modern engines have a boosting system thus
necessitating the engines to be designed to withstand a higher peak combustion pressure. The mentioned SAE paper
has a proven design for a 2-liter cylinder block, but the maximum peak cylinder pressure is only about 85 bar
representing the naturally-aspirated engine. Thus, the new proposed design simulating a boosted engine with
maximum pressure up to 120 bar requires modifications to be made especially to the critical fasteners in terms of the
bolt designs, engaged thread and the structural reinforcements of the bolt bosses. The cylinder block was modelled
using CATIA V5 software and stress analysis of the baseline and proposed designs were done using the same
software to analyse the critical area and force distribution. Two main areas have been investigated which are near
cylinder head bolt thread area and near crankshaft bearing cap thread area. It was found that, the alterations manage
to increase the factor of safety and eliminating the concentrated force at certain locations. The design modifications
made can improve the factor of safety by decreasing the stress and adding more structural strength focusing on
cylinder head bolt threaded area and crankshaft bearing cap thread area. |
