Connecting rod - General aspects - Critical cross-sections design - Materials and manufacturing )1 CFU) 4. Piston-pin - General aspects - Critical cross-sections design - Materials and manufacturing (1 CFU) 5. Piston - General aspects - Critical cross-sections design - Materials and manufacturing (1 CFU) 6. Crankshaft - General aspects - Critical cross-sections design - Materials and manufacturing (1 CFU) 7.Training (3 CFU) - Engine components design - Carrying out of an electronic spreadsheet for engine components design - 3-D CAD drawing of engine components -Preparation of simple Finite Element models.

Teaching methods

Theoretical lessons will be held in person. The exercises (during which a spreadsheet will be developed to improve the absorption of theoretical concepts, solid models of the different components will be prepared and simple Finite Element models will be implemented) will also be held in person.

Assessment methods

Verification of learning will take place through a test at the end of the course. The exam consists of a written test and an optional oral test to verify the understanding of the concepts relating to the sizing of the components of a crank mechanism of an internal combustion engine. During the written test one exercise is required (2/5 of the overall score), two open questions (2/5 of the overall score) and five multiple choice questions (1/5 of the overall score). The overall score is expressed as 30/30. The use of the calculator is allowed. For the written test the time available is 2.5 hours; for the oral exam (optional) an interview of about 20 minutes is foreseen. The results of the written test are published after about 7 days through the Esse3 platform. The positive outcome of a written test has no time limit. The result of the last written test delivered is considered. The verbalization of a positive result is carried out by registering for an oral exam, communicating whether it is intended: - record the grade of the written test without taking the oral exam; - take the oral exam (± 2 points out of 30); - integrate the total outcome (written plus possible oral) by delivering an optional project report (max 2 points out of 30) The project (possibly group) is optional. The paper must be delivered one week before the oral exam in which the outcome is to be recorded.

Learning outcomes

Learning of the main theoretical instruments for the mechanical design of an internal combustion engine. Detailed design of connecting rods, piston pins, pistons and crankshafts.
