Company

AS  -  Abt System 
The company Abt-System GmbH was founded in Frankfurt am Main, Germany, in July 2013. We have specialised from the outset in developing and manufacturing air-management systems designed to increase engine performance and reduce fuel consumption. We specialise in R&D in the field of air management for vehicles powered by combustion engines, and have developed a series of special airboxes designed to meet the commercial and legislative requirements that are likely to become applicable as exhaust-gas emission limits are reduced.

We have specialised from the outset in developing and manufacturing air-management systems designed to increase engine performance and reduce fuel consumption. We specialise in R&D in the field of air management for vehicles powered by combustion engines, and have developed a series of special airboxes designed to meet the commercial and legislative requirements that are likely to become applicable as exhaust-gas emission limits are reduced. The ABT-System configuration can be supplied as a plug-in unit suitable for adapting an existing engine layout, at reasonable cost and with few mechanical installation tasks. The ABT-System approach can also be integrated into the new technology of hybrid electric traction. Thanks to cooperation with our partners in the field, we are able to create and develop customised solutions designed to meet your requirements.

 

Energy

Improved energy efficiency based on advanced technology
ABT-System delivers boost pressure even at idling speeds. This translates into a considerable increase in torque performance for non-turbocharged petrol engines operating at low and medium revolutions, plus additional improvements in response. In the case of turbocharged diesel and petrol engines, the ABT-System configuration compensates for the "turbo lag" that occurs when exhaust pressure is too low during engine-braking overrun, changes in load and at turning speeds of between 500 and 1500 rpm. The flow rate of conventional turbocharging systems can also be increased by the ABT-System configuration, with long and medium-term cost savings based on the reduced dimensions of the turbochargers and/or compressors used.

Technology

Getting unused energy to count in an existing system
Every single percentage point counts when it comes to reducing engine CO2 emissions. Reliance on ABT-System results in economic advantages of increased performance combined with fuel savings, and also in the environmental benefits of reduced exhaust emissions. Our approach is based on conceptual innovations in the field of engine technology. ABT-System forms a decisive part of any overall approach to reducing CO2 emissions, by intervening wherever maximum advantage can be obtained efficiently. The system uses accumulated pressure and electrical energy to create an increase in boost pressure on the inlet side. The vehicle's own battery stores energy, allowing the system to operate independently of the engine. ABT-System has already produced the corresponding "proof of concept". The system operates without loss of intake at a speed of 60 kph / 40 mph. This corresponds, at 90 kph / 55 mph, to a suction speed of 25 m/s. The accumulated pressure flowing directly into the compressor can then be used for supercharging. The additional energy supplied by the electric motor allows the ABT-System configuration to increase the boost pressure on the inlet side, with minimal space requirements, from idling speed upwards and across the entire range of turning speeds. The patented arrangement of the individual components allows the flow-induced pulsation and vibration of the intake air created by increases in pressure in and around the filter to be reduced to a minimum. The ABT-System configuration consists of an axial compressor unit and a diffuser with a combined air filter. The system also includes compressor-pump protection and a mass airflow sensor, which controls the turning speed of the compressor's electric motor relative to the mass flow rate.

True to our mission to transfer racetrack innovations to the road, this system of supercharging based on accumulated pressure has already been in use in motorsport for several years. Large airboxes are used to accumulate air and create extra pressure on the inlet side. This principle has been subjected to painstaking further development by ABT-System, and optimised to a point where a unit of minimal size can generate a boost pressure and multiply it several times. The ABT-System configuration can be supplied as a plug-in unit suitable for integration into an existing system. Vehicles equipped with a 12-volt system can be fitted with electric motors with outputs ranging from 0.9 kW to 1.7 kW, while 48-volt systems can handle a range of 3.0 kW to 4.8 kW. The engine's ECU should be adapted to handle the increase in volume, in order to take full advantage of the potential extra performance offered by ABT-System.

ABT-System supplies a low-pressure turbo system designed to operate with atmospheric air. Turbocharging begins upstream of the air filter unit. Air compression increases the efficiency of combustion engines, and also acts as a range extender for hybrid and electrically-driven vehicles. ABT-System's additional contribution in this respect comes in the shape of reduced CO2 emissions. Hybrid turbocharging uses a combination of accumulated pressure and electrical power to feed unused energy back into the engine's system. The ABT-System unit is available in two configurations. One consists of an axial machine layout designed to improve the volumetric efficiency of high-performance engines, while a radial version optimises the torque curves of the diesel and petrol engines used in series-production vehicles.
