And what the heck is 'stratified' injection anyway? What does Volkswagen TSI stand for?

TSI is our pioneering technology for petrol engines. TSI engines are compact, high-powered and use less fuel. TSI technology blends the best of our TDI diesel and FSI fuel stratified direct injection petrol engines to give you excellent driveability and outstanding fuel economy. Acceleration is instant, whichever gear you're in, so overtaking is safer and you can power smoothly up hills with no delay. By adding a turbocharger and a supercharger to the fuel-injected engine hence TSI , we have developed an engine with small car fuel economy and emissions, but the power of something much bigger. The engine-driven supercharger operates at lower engine speeds with the turbocharger, powered by the exhaust gases, joining in as engine speed rises.

The TSI system combines the best features of both turbocharged and naturally aspirated engines. Like turbocharged engines, TSI engines have increased power and torque. However, unlike turbocharged engines, TSI engines do not have any lag when accelerating. This makes them more responsive and fun to drive. The heart of the TSI system is the turbocharger. The turbocharger uses exhaust gases to spin a turbine that forces more air into the engine. This extra air results in more power when combined with the right amount of fuel. To prevent the engine from becoming overloaded with too much air, the TSI system uses a stratified charge. This means that the air-fuel mixture is injected directly into the combustion chamber in multiple stages. The first stage injects a small amount of fuel, which ignites and causes the air to expand. This expansion pushes some of the unburned fuel-air mixture out of the cylinder into what is called a pre-chamber. In the second stage of injection, another small amount of fuel is injected into the pre-chamber. This ignites and causes a pressure wave that forces the remaining unburned mixture in the cylinder to detonate. This creates a more complete combustion that results in increased power and efficiency.

Unitronic Fuel System Upgrade February 19, Bimmer Invasion Orlando February 13, The thought of waking up to find your car engine shot is every Audi, Volkswagen, or BMW enthusiast's worst nightmare. In the event that happens, and you need to swap car engines , you need to know which will work best for your Audi, Volkswagen, or BMW. Although similar, there are minor variations between both engines. By the end, we hope, you'll know enough to make an informed decision on which engine to buy. The obvious difference between both engines is in their names.

Mihnea's favorite cars have already been built, the so-called modern classics from the '80s and '90s. He also loves local car culture from all over the world, so don't be surprised to see him getting excited about weird Japanese imports, low-rider VWs out of Germany, replicas from Russia or LS swaps down in Florida. Full profile. 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.

The 1. The result is a compact yet powerful engine that scores highly for both performance and economy, runs smoothly and quietly, and produces less CO2. First, a smaller and lighter engine. Decreasing engine size means less power is lost through friction, and reducing weight means the engine has less to move. Second, direct petrol injection and twincharging. Engines run by burning fuel combustion. The more efficient the combustion, the higher the power output and the lower the fuel consumption. The supercharger is powered via belt drive from the crankshaft, giving optimum pulling power even at very low revs. At higher speeds the turbocharger a system that uses the energy from exhaust gases to power the air intake that is essential for combustion joins in, making the system more energy-efficient. Volkswagen have used a number of design tricks to make the TSIs even more efficient.

So overtaking is safer and you can power smoothly up hills with no delay. How do you benefit? At the heart of TSI is a smaller engine. Volkswagen likely decided that the F was redundant, and dropping it must have saved a noticeable pile of money on badge production alone. Bimmer Invasion Orlando February 13, You're looking to buy a car in the affordable rang. What is TSI? Petrol engines. PCP vs HP — which type of car finance is right for you? Login to Your Account. Whichever suits you best depends on your driving habits.

This provides maximum pulling power on demand, even at very low engine speeds. The heart of the TSI system is the turbocharger. Tips and advice 19 Dec Your Comment. Chrome Safari Edge Firefox Opera. Exhaust manifold in the cylinder head. However, unlike turbocharged engines, TSI engines do not have any lag when accelerating. As well as being offered in pure petrol guise, TSI engines are also used in various Volkswagen Group plug-in hybrid cars. The largest of all TSI engines on offer is a 3. Remarkably, while this design is more complex, it's also more affordable to produce, making the end product - whether that's an Atlas or a humble Golf - cheaper to produce. ACT components. Simply put, stratification in engines is a type of fuel injection.
