EA2 1 1 engine is a new type of automobile engine for Volkswagen. At the same time, this series of engines is also the first engine with closed cylinder system on a four-cylinder engine, which has obvious advantages in improving fuel economy? .
Brand-new EA2 1 1 series engines, all aluminum. Firstly, it is 22kg lighter than the previous EA 1 1 series. At the same time, the fuel consumption of EA2 1 1 engine is also reduced by 8- 10 percentage points due to the reduction of internal friction and fuel consumption of the new engine and the more optimized thermal management system. It is not difficult to see from the engine anatomical diagram that the timing belt configuration of EA2 1 1 engine is restored, mainly to reduce the power consumption and noise inside the engine.
At the 20 12 Geneva International Auto Show, Volkswagen Group officially released a brand-new EA2 1 1 engine technology.
Maybe you won't be surprised by the cylinder closing system (ACT active cylinder management system). After all, some car companies adopted this technology on many models more than ten years ago, and even Volkswagen used it for a long time. But before that, this technology was more like a patent on large V8 and V 12 engines. This time, Volkswagen applied this technology to the small-displacement four-cylinder engine for the first time, which made the small-displacement engine with certain fuel-saving advantages have better fuel economy. At the same time, Volkswagen also showed us the infinite potential of traditional internal combustion engines.
