Bosch Mobility
Even in the future, two thirds of all new cars worldwide will still be driven by an internal-combustion engine. This is reason enough for Bosch to make one of the world’s most important powertrains as efficient and resource-saving as possible.

People want to stay mobile, even in a future where environmental protection is crucial. The focus will continue to be on affordability and availability. All the more reason to optimize vehicles with internal-combustion engines to address both sustainability and the demand for affordable mobility.
Heiko Weller explains how hybridization and synthetic or renewable fuels can considerably reduce the amount of CO2 emitted by vehicles with internal-combustion engines and thereby make them an important component of sustainable mobility concepts.

It was the beginning of the 1950s when Bosch launched the first gasoline direct-injection system onto the market. Nowadays, this system is still the industry standard in new internal-combustion engines. The constantly rising demand for mobility around the world means that the need for optimized fuel consumption and reduced emissions is also growing – a challenge that continues to make gasoline direct injection a key technology for the future.
Gasoline direct injection offers many advantages for drivers and vehicle manufacturers alike. Downsizing and turbocharging make fuel consumption and CO2 emissions much lower while maintaining the same output. Thanks to the high level of torque, drivers benefit from an improved vehicle response and more dynamic handling. Increasing the charge-air pressure while reducing the displacement ensures a specific output of 60–100 kW/l. Bosch has kept on developing gasoline direct injection since 1951, offering in this regard not only the very best technology to vehicle manufacturers, but also many years of technical expertise.
For gasoline engines – as for their diesel counterparts – the answer to urgent environmental concerns is an improved system approach. As an example, the use of the latest particle filters in conjunction with an innovative injection system reduces the emissions of gases and particulate matter to a fraction of the levels demanded by legislation.
As such, the influence of these vehicles on air quality is not only negligible in major conurbations.
Gasoline port fuel injection is the world’s most widespread powertrain system for gasoline engines. This system convinces with its low cost, simplified technology, and new, innovative further developments. If gasoline port fuel injection is used in engines with an output of around 60 kW/l and downsizing concepts, it offers significant cost advantages over systems with high-pressure direct injection. Thanks to the simplicity of the low-pressure system (approx. 6 bar), the complex requirements of high-pressure control can be dispensed with, while the robust combustion process even tolerates lower-quality fuels.
With port fuel and direct gasoline injection, Bosch combines two distinct fuel injection systems. Two usually separate approaches give rise to a combined system where the strengths of each subsystem ideally complement those of the other. The advantages are lower fuel consumption and reduced particle emissions. Depending on the driving situation, one of the two systems steps in and puts its respective strengths into practice. Port fuel injection impresses in partial-load operation, while gasoline direct injection’s higher knocking threshold makes it the more efficient choice at full loads.
