VW 2.0 TDI-CR Blue Motion Diesel

with SCR
Functional Engine
Description

The Christiani functional motors are mounted on a mobile frame made of high-strength aluminium profile. Instrument cluster, fuse block, as well as ignition start switch, emergency stop switch and a component simulation are installed on the control panel on the front side.

The component simulation is used to display different operating states and emergency running characteristics. By manipulation of individual sensors, the reaction of the engine management, e.g. by evaluation of measured value blocks or error entries, can be visibly traced.

At the lower front panel there is the original OBD interface and the interface for practice measuring stations. This makes it possible to connect standard workshop diagnostic systems and practice measuring stations (up to 14 in series). A pull-out shelf for measuring instruments, laptop or work documents is located below the interface plate.

With the built-in and lockable fault circuit, 24 different electrical faults can be connected within the engine control system, the voltage supply system, the fuel injection system and the fuel supply system. The resulting malfunctions enable the instructor to perform various realistic learning situations.

For troubleshooting, optional practice measuring stations or test boxes with test adapters for the engine management system are available. With these the signals and voltage values of all system-relevant parts and components can be measured or diagnosed. In addition, parallel test adapters can be installed at the plug connections of the components to which faults can be applied. This enables the electrical cable connections to be measured without disassembly, even in places that are difficult to access.

To generate the necessary signals of drive components that are not installed, the training stand has a residual bus simulation to ensure perfect function and diagnostic capability without restrictions. Rotating components and assemblies with high operating temperatures are protected against accidental contact.

All components used for real function are original components of the respective manufacturers. The superstructures shown are examples of functional engine training stands manufactured to date.

The new EA288 diesel engine series is also known as the Modular Diesel Kit, or MDB for short. The modular diesel kit creates a uniform basis for future in-line diesel engines in the Volkswagen Group which can be used across vehicle classes. The concept of the modular diesel kit is based on the fact that the engine's functional units are subdivided into modules. Depending on the requirements in terms of displacement, power output, emission standard and vehicle class, the engines can be balanced and, if necessary, configured from modified unit modules of the basic engine and add-on parts.

The 2.0 TDI engines (85/110/140kW) with Euro 6 emission standard

The 2.0 TDI engines belong to the EA288 diesel engine series. The different performance variants are achieved by means of modified engine software and exhaust gas turbochargers of different sizes. All diesel engines are equipped with the Selective Catalytic Reduction (SCR) exhaust aftertreatment system and comply with the EU6 emissions standard.

Exhaust aftertreatment with an SCR system

An effective way to reduce nitrogen oxide emissions is to treat the exhaust gas with an SCR system. The abbreviation SCR stands for Selective Catalytic Reduction. This system specifically reduces the nitrogen oxides in the exhaust gas. The nitrogen oxides (NOx) contained in the exhaust gas react with ammonia (NH3) to form non-toxic nitrogen (N2) and water (H2O). This chemical process takes place in a reduction catalytic converter. The ammonia required for the reduction process is obtained from a urea water solution, the reducing agent AdBlue®. This takes place under the influence of the heat contained in the exhaust gas. The reducing agent AdBlue® is carried in an additional tank in the vehicle and is continuously injected into the exhaust gas stream upstream of the reduction catalytic converter.
