Optimization fuel systems

It's still possible to improve engines, even after 125 years.

Bosch offers innovative, fuel-efficient, CO2-reduced drives for gasoline systems – and is constantly improving these technologies. Gasoline direct injection is the key to clean and economical driving: injecting fuel directly into the combustion chamber at high pressure cuts fuel consumption and emissions significantly.

What is more, systematic enhancements to manifold injection systems, "Advanced PFI", hold great potential to improve fuel economy. These include a series of individual measures: pressure increase, twin injection, PFI scavenging, and open valve injection.

Optimization diesel systems

Highly developed – for low fuel consumption.

Bosch is getting diesel engines in shape for the future – with innovative common-rail systems that reduce fuel consumption and CO2 emissions. Their high injection pressure of up to 2,500 bar improves combustion, which reduces both fuel consumption and CO2 emissions. This makes it possible to meet future emissions targets. There are different systems to suit anything from one-cylinder to eight-cylinder engines. They can be used for start-stop operation and designed for various qualities of fuel. Tailored local solutions are also possible, for instance for the Indian market.

Employing exhaust-gas treatment systems such as Denoxtronic reduces CO2 emissions even further. These new, improved common-rail systems can also be used in vehicles with an electric or hydraulic hybrid drive to make their fuel consumption and CO2 emissions even lower.

CO2 champion CNG

Reducing exhaust emissions with natural gas.

Bosch CNG technology makes drives clean, powerful, and economical – with high running performance and to OEM quality standards.

Bosch bi-fuel systems achieve particularly low CO2 emissions by controlling two separate fuel circuits for gasoline engines. The engine burns either methane (CNG) or gasoline. Switching between the two modes takes place during driving and is imperceptible. At the IAA Bosch is showing a bi-fuel CNG system with gasoline direct injection.

Hydraulic hybrid

High pressure for energy savings.

Hydraulic hybrids combine a IC engine with a hydraulic-mechanical drive. The system captures braking energy, stores it in a pressure accumulator, and releases it during acceleration. This solution is not only cost-effective, it is also robust and easy to maintain. It requires no charge spots and can be used around the world. Vehicles fitted with this system consume on average up to 30 percent less fuel.

Entry hybridization (BRS) - Bosch makes the affordable hybrid

A boost for the hybrid principle.

The new Bosch BRS boost recuperation system combines the advantages of start-stop technology with those of a hybrid drive – thus providing a sensible, innovative solution for compact cars. Braking energy is recovered and stored in a lithium-ion battery. This energy can then be used, for example to support the vehicle during acceleration, delivering up to 10 kilowatts of additional power. Overall, BRS can lower a vehicle's fuel consumption and CO2 emissions by up to 15 percent. The system offers automakers a great potential for meeting the ever tighter CO2 emissions standards in Europe, China, and the United States.

Plug-in hybrid systems

Fill up at the power socket to save fuel.

Plug-in hybrid vehicles combine standard IC engines with an electric drive. Since they can draw electricity from external power sources, they permit electric driving over longer distances. Whenever the electric drive is in use, the vehicle consumes no fuel. This allows plug-in hybrids to lower fuel consumption and CO2 emissions by 50 percent on average compared to vehicles that are powered purely by an IC engine. Bosch offers electric motors, inverters, regenerative braking systems, and battery systems for plug-in hybrid vehicles – not only as individual components but also as complete drive systems.


The engine that is driving the future.

Electric vehicles have no need for fossil fuels and generate no local emissions. More and more automakers are adding all-electric models to their vehicle range. As more and more electric vehicles appear on the roads, the number of public charging opportunities is also growing.

Bosch designs drive systems especially for vehicles that run purely on electricity. The battery draws electricity from external power sources such as public charge spots.

Bosch develops electric motors, inverters, battery systems, and regenerative braking systems. The company offers automakers not just individual components but also comprehensive integrated systems that are tailored to each vehicle's requirements.
