Self Study Program 68 – 1.4 CAXC 92kW TSI petrol engine with turbocharging

VAG SSP 68. Maximum force for minimum fuel consumption – these are the main highlights of the 1.4 ltr. TSI engine. By way of the downsizing concept, turbocharging and direct fuel injection, the customer’s demands were met and an engine with better driving dynamics and lower fuel consumption was developed.

The 1.4 ltr. TSI engine is the first engine of Skoda vehicles which operates according to the downsizing concept.

The basic idea of the downsizing concept is to reduce the displacement, however not to impair the engine performance. The efficiency stage of the engine is increased by reducing the displacement because the friction losses are decreased in this way. Furthermore, the engines have a lower overall weight and therefore also a reduced rotating mass.

The engines which operate according to the downsizing concept must therefore only move a reduced mass which results in a lower fuel consumption and at the same time lower exhaust emissions.
