The series includes engines with three and four cylinders and will be used from in various vehicles of the Volkswagen Group. Technology The engines of the EAevo series are based on the EA series engines used in numerous vehicles of the Volkswagen Group since There will also be a 1. The 1. The new 1. By extending the stroke from All 1. In addition, the 1. At low and medium load, the second and third cylinders are shut down. Charging and exhaust The weaker variants of the 1.
Depending on the variant, different turbochargers are used, which differ mainly in the dimensions of the turbine and compressor wheels. The 96 kW variant of the 1. This construction has been widespread in the field of diesel engines for several years, but in gasoline engines, due to the higher exhaust gas temperatures so far found only in a few models.
The engine cooling high-temperature cooling circuit is divided into two circuits, one for the cylinder block and one for the cylinder head, to accelerate warm-up. Each circuit has its own thermostat. The cooling of the cylinder head is based on the principle of cross-flow cooling. There is also a low-temperature cooling circuit for indirect intercooling.
In this cycle, the cooling of the exhaust manifold and the turbocharger is involved. The low temperature circuit has an electrically driven coolant pump, which, for example, the turbocharger can be cooled even after parking the vehicle. Variants 1.

Volkswagen Audi 1.4 TSI EA211 Engine Review
Modifications and tuning the 1. You need to keep as much low end torque as you can and aim to achieve a long power band rather than a narrow top end power spike. Forcing more fuel and air into each cylinder is the aim to any performance tuning project and direct injection engines seem pretty well setup and able to cope with decent power increases. Plenum take the air during the suck phase from the filter and allow it to be pulled into the engine cylinders with fuel for the squish phase. Structure and flow rate of the Plenum can make a big change to fuel delivery on the EA
