Reverse engineering of research engine cylinder-head

Abstract

The pursuit of increasing the efficiency of internal combustion engines is an ongoing engineering task that requires numerous research efforts. New concepts of injection or combustion systems require preliminary investigation work using research engines. These engines, usually single-cylinder, make it possible to isolate a single variable in a complex combustion mixture preparation process, thus enabling analysis of the changes being made. However, these engines are relatively expensive and their designs are offered by a limited number of manufacturers. The authors of this paper have successfully undertaken the engineering task of modifying an existing research engine cylinder head in such a way as to implement an electronically controlled variable valve timing system of the intake system. The process of reverse engineering, together with design assumptions that finally contributed to the construction of the assumed solution has been described in this paper.

Reverse engineering as a modern methods of test bed modernization

“…Now engine has a common rail injection system with a spark TJI ignition which enables it to work with gas and 3D scanning and reverse engineering as a method to develop existing dynamometers liquid fuels. Additionally, a variable valve timing system VVT-iE, which uses an electric motor to rotate the camshaft, has been added to the engine [3]. The engine head was modified to adjust for the variable camshaft phasing.…”
