The VW EA211evo (EA = development contract) is the further development of the gasoline engine series EA211 from Volkswagen AG . The series includes engines with three and four cylinders and has been used in various vehicles of the Volkswagen Group since 2017. Important features of the EA211 series have been retained, including the construction as an all-aluminum engine, four-valve technology , the drive of the two overhead camshafts ( DOHC valve control ) via a maintenance-free toothed belt and the exhaust manifold integrated into the cylinder head .
technology
The engines of the EA211evo series are based on the EA211 series engines that have been used in numerous vehicles of the Volkswagen Group since 2011. There will also be a 1.0-l three-cylinder variant with intake manifold injection and without supercharging (1.0 MPI) and a 1.0-l three-cylinder variant with direct injection and exhaust gas turbocharging (1.0 TSI). The 1.2-liter four-cylinder variants are no longer available. The new 1.5-l four-cylinder (1.5 TSI) are based on the old 1.4-l engines. By extending the stroke from 80.0 mm to 85.9 mm, the displacement is increased from 1395 cm³ to 1498 cm³.
Base engine
The cylinder crankcase is manufactured as a so-called open deck construction in die casting from the aluminum alloy AlSi9Cu3. The 1.5 TSI variant with 96 kW continues to use cast-in cylinder liners made of gray cast iron , while the 110 kW variant is coated with a plasma spray coating on the aluminum cylinder liner.
Valve train
All variants have four valves per cylinder, which are operated by the two overhead camshafts ( DOHC valve control ) via roller rocker arms. The camshafts are driven by the crankshaft via a maintenance-free toothed belt .
All 1.5 TSI engines have infinitely variable adjustment of the intake and exhaust camshafts using hydraulic phase adjusters. The 1.5 TSI also uses cylinder deactivation , which Volkswagen also calls Active Cylinder Technology (ACT). At low and medium loads, the second and third cylinders are shut down. The 1.5 TSI with 110 kW has sodium-filled exhaust valves due to the high exhaust gas temperatures .
Charging and exhaust
The 96 kW variant of the 1.5 TSI uses a turbocharger with variable turbine geometry ( VTG charger ). This design has been widespread in the field of diesel engines for some years, but has only been found in a few models in Otto engines due to the higher exhaust gas temperatures. The VTG charger in the 96 kW variant is designed for exhaust gas temperatures of up to 880 ° C, the conventional turbocharger with wastegate in the 110 kW variant for exhaust gas temperatures of up to 1050 ° C.
Volkswagen uses the brand name " TSI " for these engines . Depending on the variant, different turbochargers are used, which differ primarily in the dimensions of the turbine and compressor wheels. The 96 kw (130 PS) variant is only offered as BlueMotion at VW.
All engines have a three-way catalytic converter .
cooling
All engines are liquid-cooled . The high-temperature cooling circuit of the engine cooling system is divided into two circuits, one for the cylinder block and one for the cylinder head, in order to accelerate the warm-up. Each circuit has its own thermostat. The cylinder head is cooled according to the cross-flow cooling principle.
There is also a low-temperature cooling circuit for indirect charge air cooling. The cooling of the exhaust manifold and the turbocharger is also integrated into this circuit. The low-temperature circuit has an electrically driven coolant pump, which means, for example, that the turbocharger can be cooled even after the vehicle has been switched off.
variants
1.5 l four-cylinder (1.5 TSI)
The displacement of the four-cylinder in - line engine is 1498 cm³ with a bore of 74.5 mm and a stroke of 85.9 mm with a cylinder spacing of 82 mm. The compression is 12.5 for the 96 kW variant and 10.5 for the 110 kW variant. With this motor variant, a change interval of 240,000 km is provided for the toothed belt.
The engine code DPCA was used from model year 2020.
