Objectives of the course
The course aims to explain the issues and the design of distribution systems, intake, exhaust, fuel feeding, lubrication and cooling of IC engines. The course provides a descriptive and technical analysis of various devices in order to focalize the issues of these components.
Expected skills
Students will become familiar to the issues related to automotive engines, including problems related to its control.
Prerequisites
Basic knowledge of thermodynamics, machinery applied mechanics, fluid machinery.
The student must own appropriate knowledge of ICE.
Syllabus
The balancing of four strokes engines: forces and torques by crank. Criteria for inclusion drive shaft design and cranks phase shift and longitudinal positioning. Ignition Order. Balance of forces and torques residues by means of additional shaft. V and boxer IC engines.
Lubrication system and lubricating oil. Lubrication of crank pins and shaft plain bearing. Clearances and thickness of fluid oil in plain bearing. Antifriction materials.
Cooling systems and problems related to their design.
Intake systems in four stokes engines and variable geometry devices. Apparatus distribution laws raising valve timing and variable systems and automatic recovery of the play. Variable valve control (VVA) and innovative techniques to the engine control.
Pairing engine-compressor for the supercharger compressor mechanically dragged or propelled by gas turbine exhaust.
Adjustment and control strategies of emissions in the ignition. Internal turbulence control in combustion chambers and stratification of the charge, injection of fuel in the intake manifolds or directly into the combustion chamber (GDI).
Study of electronic injection systems for diesel engines (common-rail) and in particular Bosch electro-injector.
Adjustment and control techniques of emission by pre-injection, multiple injections and post-injections.
Laboratories and/or exercises
Disassembling of automotive gasoline engines and diesel
Bibliography
Any text of heat engines.
Revisions / Exam
Final oral exam (duration indicative 1-2 hours).
