W-9 engine design

Abstract [en]

In this thesis, the design of an internal combustion four-stroke engine is analyzed in the following areas: lubrication system, cooling system, crank train, valve train, induction system and exhaust system. It was concluded that a unique engine configuration could be made i.e. a W-9 engine (a nine cylinder engine with three cylinder rows). This W-9 engine includes many attractive properties, such as: high efficiency, a compact and stiff engine block as well as a rigid crankshaft. The whole engine was modelled in computer aided design (CAD) software and a finite element analysis (FEA) was made on vital parts. The dynamics of the engine were simulated in a multi-body simulation (MBS) software. The engine machining was performed with the latest computer aided manufacturing (CAM) software. By scientifically combine different areas and use advanced computer aid, it was possible to construct and build an automotive engine from scratch, in a comparable short timeframe. Fittings of parts were excellent. The measured weight of 105 kg together with an estimated power above 500 hp, gives a superior power to weight ratio.
