![]() ![]() Like the predecessor, the 1.4 TSI of EA211 has direct fuel injection system. The catalytic converter is mounted beyond the turbocharger for a quick warming up process. The integrated exhaust manifold reaches its optimal operating temperature very quickly after the engine is started it also cools the exhaust gases at full power mode increasing a turbocharger lifespan. A low-temperature loop flows through the intercooler and turbocharger housing. The cooling system for the 1.4 TSI has two loops. The engine has a turbocharger system with water-cooled intercooler integrated into the intake manifold. As before, the 1.4 TSI is equipped with hydraulic tappets and roller finger cam followers provided an automatically valve clearance adjustment and low friction. The 140+ hp engines incorporate both variable intake and exhaust timing. The 122 hp versions have variable intake timing only. The camshafts are driven by timing belt now (not a chain). The engine has an aluminum alloy 16-valve DOHC cylinder head with an integrated water-cooled exhaust manifold. ![]() That allows achieving more unification between cars built on MQB platform. The engine block is tilted by 12 degrees backward and the exhaust manifold is always at the back side near the firewall. The engine with new components became lighter by 24.5 kg than its predecessor. The stroke was increased to 80 mm while the cylinder bore was decreased to 74.5 mm (by 2 mm). There are a new die-forged steel crankshaft and connecting rods. First of all, the 1.4 TSI EA211 has a lightweight aluminum cylinder block with cast iron sleeves (liners) instead of complete cast iron block. ![]()
