description: 
The 1.0 TSI is the smallest engine from the EA211 family. The Volkswagen introduced the engine in 2015 as another step of its downsizing strategy. It is a 1.0-liter 3-cylinder gasoline turbocharged engine planed for the VW Polo Mk6, Golf Mk7, and other cars of the Volkswagen AG in different output versions.

The cylinder block for 1.0l TSI is made from die-cast aluminum alloy and has an open-deck design with rough-cast cylinder liners. The engine has a forged steel crankshaft with small crankshaft bearings (45 mm) and connecting rod bearings (47.1 mm) for vibration and friction reduction. The optimized moving masses of the forged connecting rods and aluminum pistons, the unique vibration damper and the flywheel with drilled holes allowed eliminate a balance shaft, despite the 3-cylinder design.

Like the 1.4 TSI EA211 engine, the 1.0 TSI also features an aluminum cylinder head with the integrated exhaust manifold. The hot exhaust gases allow the engine to warm up quickly. The cylinder head has 4 valves for each cylinder (12 valves total). The valves are actuated via roller rocker arms (fingers). The valvetrain is equipped with hydraulic valve-clearance compensators (lifters/lash adjusters). The engine has double overhead camshafts (intake and exhaust camshafts). The camshafts are driven by a toothed belt and installed in the separate camshaft housing attached on top of the cylinder head. The camshafts are not removable from that housing (it forms an integral module). The engine has the variable valve intake and exhaust timing.

The engine has a vane-type oil pump driven directly by a crankshaft. The oil system uses a continuously variable oil pressure control. That means the oil pressure is controlled in accordance with the engine load, engine rpm, and oil temperature. The max pressure produced by the oil pump is a 3.3 bar.

The high-pressure direct injection fuel system operates with injection pressure between 120 and 250 bar and uses 5-hole injectors. The excellent performance and low emissions could not be achieved without using a turbocharger. The 1.0l TSI has a turbocharger with an electronically controlled bypass flap, the charge air cooler cooled by engine coolant, and compact intake manifold made from plastic. The close-coupled catalytic converter goes after a turbocharger and lowers the emissions even better. The engine is controlled by the Bosch Motronic ME 17.5.21.
