Infiniti VC-T for an engine with variable compression (Update!) Engine-Revolution Infiniti VC-T

The Infiniti VC-T is a four-cylinder gasoline engine with variable compression as economical as a Diesel. We explain how the high-tech engine to the seemingly impossible.

The reciprocating piston engine with variable compression, the engineers dream for a long time, but in the series it didn't manage the many this concepts so far – technically too complex and therefore too expensive. However, the seemingly unhappy Situation is changing, because with the Infiniti VC-T (short for "Variable Compression Turbo") will go in the coming year, the first engine with variable compression in the new QX50 in series. And of course, the high-tech will power the Motor later on more models. The gasoline engine, the compaction has a decisive influence on the fuel consumption and CO2 emissions: the higher, the more efficient the combustion process. However, the compression also affects the performance. That is why sports cars usually are compacted less than economical. The compression to adapt flexibly to the requirements, be varied at the Infiniti VC-T engine, the stroke and the piston position at top dead center on an electronically controlled, complex kinematics.
