Self Study Program 111 – Spark-ignition three-cylinder engine 1.0L TSI 85kW series EA211

The new modern turbocharged three-cylinder 1.0l TSI 85 kW engine will replace the older four-cylinder 1.2l TSI 81 kW engine in SKODA models. With a displacement of 999 cm3, the new 1.0l TSI engine has a power output of 85 kW at 2,000 to 3,500 rpm and a torque output of 200 Nm. The engine is very refined and its performance characteristics surpass its four-cylinder predecessor.

The 1.0l TSI 85 kW engine is the first-ever three-cylinder engine deployed in the SKODA Octavia model range.

Thanks to the compact design of its aluminium block, the engine weighs only 78 kg. Great care goes into the correct balancing of the aluminium pistons and forged connecting rods, and the engine is therefore very refined even without a balancing shaft. The crankshaft is very light and the created friction losses are very low.

The crankcase and the cylinder head have two independent cooling circuits.

The integrated exhaust manifold in the cylinder head plays an important part in engine heat management.
