Volkswagen converts its 1.4 L TSI to 50/50 Technology
Volkswagen is developing its L4 1.4 TSI engine with the introduction of cutoff system, which provides partial deactivation of half the cylinders when the engine is running at constant speed and low speed.
This principle is already well known but little used except with the famous Chrysler Hemi V8 that can run on only four cylinders under certain conditions. Audi has also adopted the system of power failure of half of cylinders of an engine on its new V8 4.0 L TFSI. In the present case, the electronic management and the camshafts put out of service the cylinders 2 and 3 between 1400 and 4000 rev / min, according to the regimes the variation of couple will be from 25 to 75 Nm, but it will be done without accoups, without vibration or discomfort to the user.
This system will allow a fuel economy of 0.4 to 1.4 L/100 km, combined with the Start & Stop system, this principle will save an average of 1.0 L/100 km. Finally, note that this block 1.4 L TSI already complies with future Euro 6 standards and will be available with the 122 hp version, 200 Nm (Golf, Golf Plus, Scirocco, and probably the Audi A1 and A3 equipped with the same block) from the beginning of the year 2012.
The technology will be available afterwards on other variants of the 1.4 L but it is also possible that VW takes this technology to other engine blocks.
