TSI engines combine what Volkswagen has learned from TDI diesel tech and FSI Fuel Stratified Injection engines. In developing TSI technology it was Volkswagen’s aim to create engines that offer significant benefits by reducing fuel consumption and CO2 emissions while offering impressive power delivery.
Advantages resulting from “downsizing”
The recipe for the success of Volkswagen’s TSI engines is to be found in “downsizing.” Maximum power is obtained with minimum fuel consumption from a smaller engine. The reduction in engine size has brought better efficiency, as there is less power loss resulting from friction. The smaller engines also have the advantage of being lighter from the outset, so there’s less weight to shift in the vehicle. Volkswagen’s TSI engines take full advantage of these effects.
Gas direct injection plus charging
Pioneering technology used in TSI engines combines direct fuel injection with a turbocharger or charge compression with a turbo and a supercharger, enabling them to deliver impressive performance figures and torque as well as the full spectrum of driving pleasure despite their smaller size. Combustion of fuel is particularly efficient, with the result that power output of TSI engines is considerably higher than that of conventional, naturally aspirated engines.
Torque at all engine speeds
Volkswagen TSI engines are designed to deliver maximum torque from engine speeds as low as 1500 or 1800 rpm. This translates into driving pleasure and fuel economy. The driver can make use of superb power delivery across a wide range of engine speeds, and TSI engines can be combined to excellent effect with higher, fuel-saving gear ratios.
The benefits are quite clear when you compare them to older MPI systems: high specific torque is available from much lower revs and maintained at most rpms. This makes cars equipped with these engines more lively at lower revs, which in turn makes them more economical and cleaner. When comparing an older 1.6 105 hp VW MPI automatic with the new 1.2 105 hp TSI DSG, Volkswagen found that emissions had dropped by a very impressive 50 grams. In addition, unlike a hybrid engine powertrain which can’t keep up with with highway speeds once the battery is drained, TSIs have no such downside. In fact, the PFI (Performance Feel Index developed by the automaker) figures are even better due to increased torque. Saving money without forfeiting performance sound too good to be true and yet it is available in the all new VW Beetle 1.2 TSI.
The Beetle 1.2l TSI Design is priced at RM131,888 and RM142,888 for the 1.2l TSI Sport.
