Germany’s ADAC (Allgemeiner Deutscher Automobil-Club e.V.) recently awarded its much coveted “Yellow Angel” (Gelber Engel) awards for the ninth year in a row. Among the winners was a natural gas vehicle, the three-cylinder natural gas powered Volkswagen eco up! which relies on a Bosch injection system to regulate the supply of natural gas as well as gasoline. The eco up! was named “Best Innovation” in the “Innovation and Environment” category.
Bosch worked with Volkswagen to apply the injection technology found in the three-cylinder engine with 1.0 liter displacement in Volkswagen’s eco up!. Bosch supplies the engine management system, injectors for natural gas and gasoline, the gasoline rail, and the lambda sensor system, as well as a mean pressure temperature sensor.
The vehicle can run either on gasoline or on compressed natural gas (CNG). Its engine delivers 50 kW (68 horsepower) at 6,200 rpm, reaching a maximum torque of 90 Nm at 3,000 rpm. In the New European Driving Cycle (NEDC) the eco up! consumes just 2.9 kilograms of natural gas over 100 kilometers, corresponding to CO2 emissions of just 79 grams per kilometer.
Burning natural gas produces up to 25 percent less CO2 than gasoline, making CNG a particularly eco-friendly form of fuel, and the vehicle’s carbon footprint is even smaller when running on biogas.
The “Yellow Angel” awards are given every year by the German Automobile Association (ADAC) and are among the most prestigious honors in the automotive sector, highly coveted by manufacturers and suppliers alike. The ADAC gives awards in five categories: “Car,” “Innovation and Environment,” “Future,” “Quality,” and “Personality.”
