Auto Guide While other automakers are playing with the idea of mass-market hybrids and electric cars, Volkswagen Group has continued to rely on its family of petrol engines as it tries to take the no. And as far as engine families are concerned, none are as well known and especially widespread as TSI. TSI is available on an increasing number of our cars, from Polo to Passat.
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. Saving money without forfeiting performance sound too good to be true, which is why we need to examine Turbo Stratified Injection further. The first driving principle behind the system is direct fuel injection. This ensures less pumping losses and a more efficient combustion, thus increasing fuel economy.
The TSI engine combines direct injection with turbocharging and in some cases even twincharging, as the some performance-oriented 1. Another important component for a successful TSI is an intercooler to reduce the temperature of the air coming into the engine and thus allow more of it to come in and reduce the posibility of detonation, or engine knocking. An easily overlooked element of TSI technology has always been downsizing: 3-cylinder engines replacing 4-cylinder one, 1.
Volkswagen never stops inventing new technology to make their TSI engines competitive. The older 1. Here are some of the most important and widespread TSI systems It shows Volkswagen wants its customers to have a downsized alternative, just like the 1L engines offed by Opel and Ford.
The first major application of this 3-cylinder TSI was come with the Polo facelift. However, soon after its launch Audi also introduced the A1 ultra with the same setup, followed by the Skoda Fabia. The engine is derived from the 1-liter in the VW Up!. There are two different versions available. The most powerful one delivers PS 81 kW and Nm of torque from 2, rpm. They have a cast aluminum alloy block for lightness and die-forged steel crankshaft for strength.
This family of four-cylinder turbocharged engines is produced by Skoda Auto at the Mlada Boleslav. All use demand-controlled injectors which eliminate the need for a return fuel system. The single turbocharger offers 1. The 1. Audi also offers it on both the A1 and the A3. Three different output versions of the engine, with increased performance and production costs. First offered on the Golf 6 as an alternative for the 1. A 90 PS 66 kW version of the same 8-valve engine engine was launched on the Polo 5 in It delivers its output rpm lower but has the same Nm lb-ft torque levels.
These engines have four valves per cylinder and offer improved performance. Based on the EA that has been around since the original VW Polo and the Audi 50, the new engine used a turbocharger and a supercharger to offer PS, replacing the 2.
At engine speeds just above idle, the belt-driven supercharger provides a boost pressure until the engine reaches 3,rpm. Just like the EA 1. The newly developed generation of the 1.
Like the EA generation of engines they replaced, they use iron because this has better acoustic damping properties compared to aluminum. Expected to be universally available for all markets on five continents, the 1. The EA generation of 1.
Commonalities are limited to FSI direct injection, cooling systems and spacing between the cylinders. Latest car models:.
Volkswagen Audi 1.5 TSI EA211 Engine Review
Home Volkswagen Audi 1. It is assumed that the new 1. The 1. The crankcase cylinder block has the new design of water jacket and is made from aluminum alloy also. The 96 kW 1.

EA[ edit ] The EA series of internal combustion engines was introduced in the mids in the Audi 50 , and shortly after in the original Volkswagen Polo. It is a series of water-cooled inline three- and inline four-cylinder petrol and diesel engines , in a variety of displacement sizes. This overhead camshaft engine features a crossflow cylinder head design. The camshaft is driven by a toothed belt from the crankshaft, this belt also provides the drive for an intermediate shaft that internally operates the oil pump and ignition distributor. Other "V" belt driven accessories are the water cooling pump, alternator and if fitted power steering. In transverse mount configuration the exhaust side is towards the vehicle firewall, in longitudinal configuration the exhaust side is to the right as you face front in either left or right hand drive vehicles.
Volkswagen Audi 1.4 TSI EA211 Engine Review
Gohn This is a new V12 engine developed for Lamborghini. Another important component for a successful TSI is an intercooler to reduce the temperature of the air coming into the engine and thus allow more of it to come in and reduce the posibility of detonation, or engine knocking. The cylinder block for 1. In order to achieve these ambitious targets, a large number of technical innovations have been combined in the new EA TSI evo, which have been considered in a new kind of combustion process. The engine block is tilted by 12 degrees backward and the exhaust manifold is always at the back side near the firewall. During this time, numerous innovations have come onto the streets.
