For higher fuel efficiency: SC60 brings Start/Stop to compact cars

For higher fuel efficiency: SC60 brings Start/Stop to compact cars

  • SC60 is a Start/Stop starter motor tailor made for downsizing – saving 8% fuel in real world
  • India is the first market worldwide to introduce the product. Test.

Stuttgart/Bangalore, 18.09.2018– Start/Stop is an important technology to make cars more environmentally friendly, offering immediate fuel efficiency increases of up to 8%. However, it was previously available almost exclusively in larger cars. The new SC60 Start/Stop starter motor by SEG Automotive remedies this situation: it is among the smallest of its kind in the world and able to fit in compact cars with small combustion engines, yet it provides up to 1.2kW starting power. The SC60 is based on the C60 Starter, which has been tremendously successful with OEMs across the world.


World premiere in the Indian market

The product was engineered in Germany with emerging markets and compact vehicles in mind and fittingly, it has now been premiered in India by both domestic and international OEMs. Today, air pollution is a major problem in the country - the WHO counts 12 Indian cities among the 25 most polluted in the world. The SC60 is an efficient answer to reduce pollution by decreasing fuel consumption and help OEMs reach increasingly more stringent CAFE goals.
“We are pioneers of Start/Stop, having introduced the technology in 2007, and have since seen it bring efficient CO2-reductions to a large share of the European, US and Chinese market. With the new extra-compact SC60 we are confident that the technology will now also conquer developing markets like India, since it perfectly serves the smaller cars which are prevalent there,” states Peter Sokol, COO of SEG Automotive.
SEG Automotive has ongoing projects that aim to also roll out the new product to other OEMs in India and other markets like Brazil, China and Europe, further solidifying its role as technology leader and one of the most significant global suppliers.


Background information: How does Start/Stop work?

The engine control unit (ECU) automatically switches off the engine if the vehicle comes to a stop and the driver puts the gear into neutral, for example at a traffic light. For cars with automatic transmission just the pressed brake pedal and vehicle standstill is required. As soon as the driver presses the clutch again or in case of automatic transmission releases the brake, the engine is re-started automatically. Start/Stop works conveniently in the background, and evaluates a wide array of sensor information before being activated. For instance, a battery sensor determines the battery’s level of charge; only if a quick restart is guaranteed, the engine will be switched off when the vehicle is stopped.
Another example is the vehicle’s air conditioning. If the cabin temperature is too cold or too hot, the engine will continue to run to more quickly achieve the occupants’ desired temperature. Finally, there is a DC/DC converter for stabilizing the voltage of the electrical system during starts to ensure that the radio, navigation system, or hands-free telephone operate without any interference or interruption. Advanced Start/Stop
Engineers are continually working to extend engine shutdown times in order to further reduce consumption, and thus CO2 emissions. Advanced Start/Stop therefore also turns off the engine when the vehicle is coasting to a stop and is already at low vehicle speed. Depending on the style of driving and the traffic conditions, the advanced Start/Stop system from SEG Automotive can save up to 10 percent of total fuel consumption.


Other products by SEG Automotive that contribute to reduction of CO2 emissions

In parallel, SEG Automotive is pursuing a range of additional projects to further decrease CO2 emissions of passenger cars and commercial vehicles. With the Boost Recuperation Machine (BRM), which facilitates 48-volt mild hybridization, SEG Automotive already offers a technology for hybridizing gasoline and diesel engines in a cost-effective manner. The BRM enables regenerative braking, storing energy that is later converted into additional driving power, delivering extra torque during acceleration and allows “coasting” at high speeds with the engine turned off. Through the use of BRM fuel consumption and CO2 emissions can be further reduced by about 15 percent. SEG Automotive also offers a broad range of high efficiency generators for any power requirements, which keep the vehicle’s electrical system stable and reduce CO2 emissions and fuel consumption.
