General Motors Europe has freshened up its Polish-built Suzuki Wagon R clone, the Opel and Vauxhall-badged Agila, with revised front and rear styling, a brighter interior, and a 60 hp 1.0 litre engine that features new twinport technology.
Twinport builds on the standard four-valve technology to achieve fuel savings with a variable intake manifold in combination with a high rate of exhaust gas recirculation. Under ‘partial load’ the engine receives an additional 25% of its fuel air mixture from the already burnt exhaust gas recycled back into the mix.
The advantages of twinport technology are achieved through a combination of fuel injection and exhaust emission control by three-way catalytic converter technology. This reduces technical complexity and consequently the cost to the customer, making the twinport solution particularly attractive for compact-class cars, as power output and efficient fuel consumption are maintained.
The new twinport three-cylinder engine is claimed to “dramatically increase” engine efficiency to up to 48.7 mpg, up nearly two mpg over the previous 57 hp model, while delivering more torque.
Both the twinport and existing 75 hp 1.2 litre Ecotec engine comply with Euro 4 emission standards, which do not become mandatory until 2006.
