Next step in ef­fec­tive en­gines

The Witness - Wheels - - MOTORING -

NIS­SAN’s e lux­ury ve­hi­cle di­vi­sion, In­finiti, has to date seen lit­tle sales in South Africa and rel­a­tively few around the world, but this may all change if Infinity’s new 2.0-litre, four cylin­der turbo en­gine with vari­able cylin­der com­pres­sion lives up to the hype.

Pres­i­dent of In­finiti Roland Krueger de­scribed the new en­gine as “a revo­lu­tion­ary next step in op­ti­mis­ing the ef­fi­ciency of the in­ter­nal com­bus­tion en­gine”.

Krueger said this tech­no­log­i­cal break­through de­liv­ers the power of a high-per­for­mance 2.0-litre turbo petrol en­gine with a high level of ef­fi­ciency at the same time, mov­ing be­tween com­pres­sion ra­tios of 8:1, which al­lows high turbo boost; and 14:1, which al­lows the pis­tons to just sip while cruis­ing. Infinity said it can vary the com­pres­sion by rais­ing and low­er­ing the top and bot­tom points of the pis­ton stroke with­out mov­ing the crank­shaft or the cylin­der head, in­stead us­ing an ac­tu­a­tor arm that changes the angle of a multi-link that sits around the crank­shaft

The en­gine goes on show at the 2016 Paris Mo­tor Show at the end of Septem­ber, when power specs will also be an­nounced.
