Diesel? What’s that?
Volkswagen is embracing a far less controversial type of gas with its new 1.5-liter TSI engine, unveiled yesterday at the Vienna Motor Symposium.
The ultra-efficient four-cylinder uses variable turbine geometry (VTG) in the turbocharger to generate peak torque at a low 1,300 rpm, then maintain a flat twisting curve until about 4,500 rpm. This leads to fuel economy increases and a better driving experience.
Used previously through Porsche, VTG technology changes the turbocharger turbine guide vane position to optimize compressor speed for a given speed and cargo. This helps?build up boost in a hurry at reduced engine speeds as well as manages it better at higher speeds.
Volkswagen’s new direct-injection motor uses the Burns combustion cycle and has a compression ratio of 12.Five:1. This technology, in addition cylinder deactivation, a friction package and a VTG turbocharger, reduces fuel consumption in order to 10 percent below that of its well-regarded 1.4-liter TSI engine.
That particular engine tends to make?39 miles per gallon on the highway in a Jetta with an automated transmission, so it’utes an impressive achievement.
“An important aspect here is that the improvements in gas mileage take effect across a wide range of the engine chart,” the automaker said in a statement. “As a result, they do not merely utilize under test bench conditions but also have a distinct impact on the actual customer’s everyday traveling.”
The automaker showed off 2 versions of its 1.5-liter in Vienna?- a 130 hp edition and a higher-output 150 hp, with the lower-end engine producing 147 pounds-feet of torque. Absolutely no applications are outlined, but Volkwagen said it plans to start offering the One.5-liter in its lineup later this year.
