On the initiative of Vianney Rabhi, MCE-5 DEVELOPMENT is founded by a team of engineers led by David Rabhi I Feasibility studies and preliminary tests of VCRi technology

Vianney RABHI

Vianney Rabhi is the inventor of MCE5’s VCRi technology. He filed his first internal combustion engine-related patent in 1985. He soon understood the value of variable compression ratios (VCR) and anticipated many applications for them, especially their use in optimizing the implementation of extended expansion combustion cycles.

In 1991, Vianney Rabhi filed his first variable compression ratio engine patent and established an inventory of the essential functional features that a VCR engine must exhibit. In 1997, the idea of a rack-and-pinion transmission came to him, which met most of the functional criteria of his inventory. A few months later, he filed the first related patent, the one on which the VCRi technology is based.

Between 1997 and 2000, he filed several patent improvements and obtained funding for a first design optimization of the VCRi mechanism. In 2000, MCE-5 DEVELOPMENT was founded on his initiative. A first car manufacturer took interest in the project, leading to a collaboration that continued until 2004.

Vianney Rabhi directed the main strategic and technical orientations of the Company until 2012, taking charge of the commercial promotion of VCRi to the world’s leading car manufacturers and presenting the project to French and European public institutions funding research. From 2013 onwards, the company’s structuring and management efforts since 2009 enabled Vianney Rabhi to reduce his operational activities with MCE5 and devote himself more intensively to his core activity of independent inventor.
