The innovative 1.0 TSI in the new VW up! GTI has been named International Engine of the Year 2018. The 85 kW / 115 HP petrol engine is the first of its kind to be combined with a four-way catalytic converter and installed in the up!. It also comes with a petrol particle filter. Exhaust gas after-treatment paired with features inside the engine enables the power source on board the up! GTI to meet the new EU 6AG (Euro 6d-TEMP) emission standard.
A detailed looked at the engine and emission control system: The 1.0 TSI version of the up! GTI – available since spring this year – is the latest addition to the EA211 range of engines. The 999 cm3 award-winning engine contains a turbocharger with electric wastegate actuator, an intake manifold with integrated intercooler and an exhaust manifold integrated into the cylinder head. With a pressure of 350 bar (high for a petrol engine), the fuel mixture is injected directly into the combustion chambers. Thanks to these features, the compact, lightweight four-valve engine delivers 115 HP at between 5,000 and 5,500 rpm. From 2,000 rpm, the 1.0 TSI – which is fitted with two adjustable camshafts – balances a force of 200 Nm to the drive axle. The maximum torque remains constant up to 3,500 rpm.
One key aim when developing the new TSI was to ensure the lowest possible emissions. This was achieved with new tech, such as the new 5-hole piezoelectric injector, high injection pressure, newly developed turbocharger, new pistons and innovative emission after-treatment system. A core element of the emission after-treatment system is a new four-way catalytic converter with integrated petrol particle filter (OPF). The OPF reduces particle emissions by 95 percent. A second three-way catalytic converter in the underbody guarantees that the threshold specified in EU 6AG is complied with – even under heavy loads.
The EU 6AG (Euro 6d-TEMP) emission standard includes fuel consumption measurements according to the new, realistic Worldwide Harmonised Light Vehicles Test Procedure (WLTP) and Real Driving Emissions (RDE) test. The measurements are made on a dynamometer and under real conditions on the road.
A one-litre engine is no odd thing these days, the VW Golf 1.0 TSI, Ford Fiesta, Audi A1, and Q2 already feature 1.0-litre 3-bangers on sale in Singapore.
