The Audi A2 1.4 TDI with 55 kW/75 bhp engine now complies with the stringent European emission standard EU4. This will please the customer for two reasons: they benefit from a tax advantage of up to 614 and from the unchanged basic price of 18,300.
This means that the entire A2 model series already complies with the most stringent emission limit to date, which is not due to become law for newly registered vehicles until 1 January 2005.
This progress has been made possible by extensive detail work on the engine and high-pressure injection system. Exhaust gas recirculation is now electrically controlled and the efficiency of the EGR cooling system has been significantly improved. A map-controlled shutoff valve in the intake manifold assists mixture preparation.
The entire pump-injector fuel injection system has been modified in detail and the pressure level increased further. The newly tuned engine management with EOBD (European On-board Diagnosis) and pilot injection as well as the further increased precision of the injection elements have a positive effect on emissions and acoustics.
Shielding measures on the intake manifold and cylinder block round off the extensive modifications that have been made to this high-performance engine. The acoustic quality of the three-cylinder engine has also been significantly improved as a result.
