Miniaturised cylinder head production by rapid prototyping
Melo, Rodrigo; Monteiro, A. Caetano; Martins, Jorge; Coene, Stijn; Puga, Hélder; Barbosa, J.This work shows the development of the design and manufacturing of a very small engine, namely its head. The engine works under the 4-stroke cycle, therefore having a very complex cylinder head, housing the camshaft, valves and its auxiliaries (seats, guides, springs), spark plug, inlet and exhaust passages and a coolant chamber. The geometries, both inner and outer are highly intricate which makes the producti...
Design of an inlet track of a small I.C. engine for swirl enhancement
Martins, Jorge; Teixeira, S. F. C. F.; Coene, StijnThe purpose of this project was to re-design the inlet port of a small Internal Combustion Engine in order to enhance the production of turbulence by swirl. A good swirl promotes fast combustion and improves the efficiency. A small internal combustion engine was designed to be part of a very efficient vehicle to enter a consumption marathon. The engine should run at low speeds, in order to have low mechanical l...
