Audi introduces new CNG A3 Sportback

Green Car Congress

The cylinder head, injection system, turbocharger and catalytic converter were modified accordingly for the CNG engine. Operation with the knock-resistant fuel CNG enables a higher 12.5:1 1 compression ratio compared with the conventional combustion process of the 1.5 TFSI 110 kW (150 PS) and also improves efficiency.
