Self Study Program 443 – The 1.2L 77kW TSI engine with turbocharger
VAG SSP 443. This 1.2l 77kW TSI engine replaces the 1.6l 75kW engine with intake manifold injection. Compared with the latter, this engine achieves significantly better performance with significantly reduced fuel consumption and therefore lower CO2 emissions. The aspect of CO2 emissions has now become an important factor which influences the customer’s purchasing decision.
Volkswagen is consistently pursuing its TSI strategy and is continuing this engine family’s success story with the new 1.2l TSI engine. The further development of the engine technology used in this small but powerful engine model series is based on consistent output optimisation and lightweight design. With its new aluminium cylinder block and a newly developed combustion process, this engine combines response plus low consumption and costs for Volkswagen’s high-volume engines.
On the following pages, we will introduce you to the design and function of the new 1.2l 77kW TSI engine with turbocharger.
Further information on engine mechanics and engine management can be found in self-study programme 405 “The 1.4l 90kW TSI Engine with Turbocharger”.
