Engine
The basic layout
The 1.4-liter TSI is an in-line 16V four-cylinder engine of the new EA111 engine generation with 1,390 cm3 displacement, cylinder spacing of 82 millimeters, a bore/stroke ratio of 76.5 to 75.6 millimeters, electronic gasoline direct injection, electronic-mapped ignition with cylinder-selective anti-knock control, turbocharger and intercooling. The TSI exhibits 10:1 compression, which is relatively high for a turbocharged engine and is fueled with more economical super (95 ROZ) fuel. A new generation of pumps ensures optimal buildup of high pressure in the injection system.
A primary focus in the development of the third TSI was to reduce friction losses even further. Advanced development of the combustion process and a redesign of the intake port made it possible to do without charge movement flaps in the intake port. Simultaneously, an absolute requirement set forth in the specification was that the car must be able to achieve a level of agility similar to that of the twincharged TSI engines. And that was not all that was required: The TSI also had to be able to serve as a mass-produced engine for model series ranging up to the Passat.
The 90-kW engine shares the following components with its two stronger brothers:
- Gray cast iron cylinder crankcase in open deck construction (ensures optimal cooling in the upper cylinder area).
- Timing case that integrates the oil filler, crankcase venting and oil filter module.
- Valves are driven by a robust and practical, hydraulically-tensioned toothed chain.
- Steel crankshaft.
- Connecting rod.
