In the medium term, the number of newly registered vehicles with internal combustion engines will continue to increase around the world. For this reason, legislation to limit CO2 emissions has been introduced in several regions. In Europe, for instance, the CO2 emissions of an average passenger car will have to be reduced from 130 grams per kilometer today to 95 grams in 2020. In terms of average fuel consumption, this is the equivalent of four liters of gasoline or 3.5 liters of diesel per 100 kilometers. Thanks to modern drive technology, Bosch believes this is a realistic aim. The company has already developed many fuel-saving technologies.

These include:

Gasoline direct injection: As early as 1951, Bosch launched a technology for gasoline engines. The system sprays fuel at high pressures directly into the combustion chamber. This enables higher engine compression, which translates into greater efficiency. As a result, gasoline engines with direct injection can perform better and are more fuel-efficient. Combined with downsizing and turbocharging, gasoline direct injection contributes to a CO2 reduction of up to 12 percent. Since the year 2000, an equivalent technology has also been available for diesel vehicles.

Coasting function: With the start/stop system, driving vehicles that operate with diesel or gasoline engines can be emissions-free, noiseless, and low-resistance over considerable distances. The engine is automatically turned off whenever the vehicle can maintain its speed while coasting, for instance on slopes or when rolling to a halt. On average, coasting reduces fuel consumption by up to 10 percent.

Predictive navigation: Predictive navigation is one of Bosch’s most recent innovations for more driving comfort and lower fuel consumption. The system connects map data with the vehicle’s drive system. Using the preview of the road ahead, the engine management system can automatically determine how much power the powertrain needs and controls the internal combustion engine. This enables fuel savings of up to 15 percent.
