John Moore, CEO van Antonov:
"De Verenigde Staten van Amerika vertegenwoordigen een van 's werelds grootste markten voor tunerproducten. Het feit dat we hier het Antonov drive system succesvol hebben gedemonstreerd geeft ons de mogelijkheid met bewezen techniek de markt te veroveren.
Het vormt verder een stevige basis voor onze discussie met - met name Europese - autoproducenten die geïnteresseerd zijn in globale toepassingen van systemen gericht op het terugdringen van CO2 emissiewaarden, waarvoor Antonov een aantal andere producten in een verregaande staat van ontwikkeling heeft".
Volgens bestuursvoorzitter John Moore van Antonov vormen de nieuwe ontwikkelingen 'een stevige basis' voor zijn discussie met - met name Europese - autoproducenten die geinteresseerd zijn in wereldwijde toepassingen van systemen gericht op het terugdringen van CO2-emissiewaarden. Hiervoor heeft Antonov 'een aantal andere producten in een verregaande staat van ontwikkeling', zo stelt de bestuurder.
Volgens Antonov geeft de supercharger een kleinere motor hetzelfde vermogen als een zware motor, met minder brandstofverbruik en minder CO2-uitstoot

(Novum/Betten) - Antonov heeft woensdag tot 18,75% hoger genoteerd op de Amsterdamse beurs. Omstreeks 13.30 uur wint het lokaal genoteerde aandeel 14,6% op EUR 0,55, bij een omzet die bijna achtmaal hoger ligt dan het tiendaags gemiddelde.
Beleggers reageren enthousiast op het nieuws dat de bedenker van versnellingsbakken tijdens een autoshow in Las Vegas een Hummer H3 zal presenteren die is uitgerust met een '2 speed supercharger' van Antonov.
De supercharger zorgt ervoor dat 58% meer vermogen op de wielen wordt overgebracht in de versnellingsfase, waardoor de performance van de auto 'geheel' wordt veranderd, aldus Antonov in een vanochtend uitgebracht persbericht.
Volgens chairman Christopher Ross is de supercharger een product dat in relatief korte tijd naar de markt kan worden gebracht. Verder meldt hij positieve reacties op het product te ontvangen.
Naast het succesvol aanbrengen van de applicatie in zwaardere auto's als de Hummer, verwacht Ross ook een grote markt voor het toepassen van de 2 speed supercharger in auto's met een kleinere motor.
De supercharger geeft, zo stelt hij, een kleinere motor hetzelfde vermogen als een zware motor, met minder brandstofverbruik en minder CO2-uitstoot. "De technische ontwikkelingsfase is nu voorbij, de toepassing is zo goed als klaar voor serieproductie", aldus Ross.

Antonov showcases design and technical capabilities at Engine Expo
9 May 2007
Antonov Automotive Technologies, the UK-based transmission research and development company, is showcasing its design and technical capabilities this week at the Engine Expo exhibition being held at Stuttgart in Germany. The 3-day exhibition is one of the world's leading annual events for the vehicle powertrain and driveline engineering community.
Antonov’s wide ranging transmission technologies include the world’s first 2-speed supercharger drive system to enter series production. This technology, which has recently made the transition from technical concept to initial low volume manufacture, is currently being demonstrated to prospective customers in the tuner and OEM market in a Chevrolet Lacetti, Ford Mustang and Hummer H3.
Figures released at the show provide further evidence of the dramatic enhancement in the performance of vehicles equipped with an Antonov 2-speed supercharger. Since announcing its latest Hummer H3 demonstrator at the SEMA show last year, Antonov has obtained measurements for the vehicle’s 0-100kph time, which has been virtually halved from 13.6 to 7.3 seconds compared with the base vehicle. On/off road performance, which is a particularly important characteristic for this class of vehicle, shows an equally impressive reduction in the time required for a hill climb, which has been reduced from 15 to 10 seconds. The difference in the Hummer’s terminal speed at the hill summit has increased from 52 to 82 kph when comparing the base vehicle with the 2-speed supercharger.
“There is a dramatic improvement in the driveability of the Hummer when equipped with a 2-speed supercharger with little effect on fuel economy,” said Antonov chief executive John Moore. “This results from the significantly improved low speed engine torque, which we have similarly demonstrated in our Chevrolet Lacetti and Ford Mustang demonstrators.”
The commercial potential of an Antonov step-up drive applied to a centrifugal pump supercharger lies in its ability to increase the power and torque of an engine at low engine revs. The application of a 2-speed drive - which is based on the Antonov Mechanical Module (AMM) - enables a supercharger to be better matched to the engine. By driving the pump faster at low engine speeds, a higher boost ratio can be obtained to provide additional low speed engine torque. As engine speed rises the unit automatically changes up to enable the supercharger to continue to operate effectively at higher engine speeds. The ability of the mechanism to operate as a passive mechanical device without the need for electronic control systems or hydraulic actuators means low cost, high efficiency and simplicity of application.
Antonov anticipates demand for its supercharger drive system will come from carmakers needing to downsize engines in pursuit of better fuel efficiency and reduced CO2 emissions. Smaller displacement engines have less torque at low engine speeds, which adversely affects the driveability of the vehicle and its engine performance characteristics. Hence the need to compensate with forced induction systems. The benefit of the Antonov 2-speed supercharger is that the torque curve of a small displacement engine can be tuned so that it matches the performance of a much larger naturally aspirated unit. This is equally applicable to diesel and gasoline engines.
At the show Moore was also able to report on the company’s progress with its TX6 6-speed transmission system, which is currently being prepared for high volume manufacture by the Chinese carmaker Geely.
=======================================================
When it comes to downsizing engines for reduced fuel consumption and CO2 emissions, the automotive research and development engineers at Antonov reckon a simple dual-speed mechanical approach is the optimum solution when considering supercharging.
‘Two speeds are better than one,’ says Chris Baylis, operations director at Antonov Automotive Technologies based at Warwick in the UK. ‘And two speeds are enough – particularly when considering the cost, weight, packaging and vehicle refinement implications for high volume car production.’
‘Motorists have come to expect a certain level of performance from their vehicles, and while as an industry we strive for ever lower fuel consumption and CO2 emissions we have to keep driver expectations and vehicle performance in mind when making engines smaller,’ said Baylis.
‘Car makers are increasingly looking at superchargers to enhance the performance of small engines. Unlike turbochargers, there are no heat issues to manage, and the study of exhaust gases can then be assigned to energy recovery systems,’ he added. Using the dual-speed approach, Antonov reckons that car makers could halve the size of the engine for any particular application with a dramatic reduction in fuel consumption and carbon emissions.
‘A 25 to 50 per cent reduction in engine size seems feasible for road vehicles,’ says Baylis. ‘The dual-speed supercharging solution certainly delivers the performance and, importantly for road cars, maintains excellent driveability. Improved fuel economy is fundamentally achieved through using a small displacement engine, with a dual-speed supercharger allowing it to run more often at low rpm. The two speeds allow us to spread the charge of air from the supercharger to the engine over a wide engine speed range,’ he adds.
‘Essentially, we’re able to create a better match between the supercharger and its host engine – by running the supercharger faster at low engine speeds and slower at high engine speeds. The benefit is predictable low speed engine torque that is always available for enhanced drivability and performance. The change between drive ratios is smooth and virtually imperceptible to the driver,’ says Baylis.
‘The ability of a dual-speed supercharger to operate as a passive device, without the need for sophisticated and expensive electronic control systems or hydraulic actuators, means low cost, high efficiency and simplicity of application. In addition, a supercharger with a simple dual-speed mechanical drive provides most of the benefit of a fully variable drive unit, or various complex combinations of supercharger and turbocharger, at a fraction of the cost,’ he adds.
Three dual-speed supercharger studies are currently being pursued by Antonov. This includes an engine downsizing application for a typical family car, an aftermarket application already in production for high performance vehicles and a performance enhancement application for off-road vehicles. So does this mean that in another five years, we’ll all be driving supercharged Santros, Zens and Sparks? Stay tuned…!
