Self Study Program 652 – Audi 4.0L V8 TDI engine of EA898 series

VAG SSP 652 – Audi 4.0L V8 TDI Engine of EA898 Series: High Performance, Efficiency, and Sustainability. Self Study Program 652 provides a detailed look at the design and function of the 4.0L V8 TDI engine of the EA898 series, offering technicians an understanding of the engine’s structure, coolant pump, electric powered compressor (EPC), and charge pressure control system.

As a source of superior driving power in the premium segment, the V8 TDI engine offers high traction and ample power reserves in any driving situation. The electric powered compressor (EPC) contributes to good driveaway performance, and the derivatives of the new engine generation are available with power spread from 310 kW to 320 kW, maximum torque of up to 900 Nm, and certification to EU6 (ZG), EU5, and ULEV125 emission standards for export markets.

The state-of-the-art technologies implemented in the V8 TDI engine were designed to achieve high engine power output and torque for sporty positioning in an S model, low fuel consumption for high efficiency in the high-performance segment, low and sustainable emissions certified to EU6, EU5, and ULEV125 exhaust emission standards for worldwide use, spontaneous power delivery and optimal drive-away performance, and a high level of comfort.

By completing Self Study Program 652, technicians will be able to identify the structure of the components located in the inner V, describe how the coolant pump is driven and switched off, understand the voltage applied to the EPC, and explain how the charge pressure control system works.

This program is a valuable resource for technicians interested in the advanced technologies and performance capabilities of the 4.0L V8 TDI engine of the EA898 series in Audi vehicles.
