TULA DEVELOPING DYNAMIC SKIP FIRE TECHNOLOGY FOR ALL ENERGY SOURCES
Auto Tech Review|June 2020
Ever since its introduction to the market in 2019, Silicon Valley-based Tula Technology’s innovative cylinder deactivation technology, Dynamic Skip Fire, has found increasing acceptance in the North American market, with General Motors selling over half a million units featuring this proprietary technology. In its effort to further improve vehicle fuel efficiency and emissions, the company has now collaborated with global power leader Cummins on a significant technical demonstration of diesel Dynamic Skip Fire (dDSF). DSF as a technology, nonetheless, is not limited to petrol and diesel alone.

TULA DEVELOPING DYNAMIC SKIP FIRE TECHNOLOGY FOR ALL ENERGY SOURCES

Cleaner mobility, aided by the electrified powertrain, has been the subject of intense discussion and debate world over. Most developed and many developing countries have committed to completely do away with fossil fuel-based, internal combustion engine (ICE) vehicles over the next couple of decades. Of course, this has led many companies to completely overhaul their business strategies. It is interesting that, in such times, there are companies that wholeheartedly believe in the sizeable opportunity in improving vehicle efficiency and reducing emissions.

One such company is the Silicon Valley-based, 12-year-old, Tula Technology, which specializes in controls technology to optimize propulsion efficiency across vehicle segments and energy domains – petrol, diesel, hybrids, electrics, and other alternative fuels.

Tula’s genesis is in itself a fascinating story. Adya Tripathi, the company’s founder, and Chairman, had a background in digital audio amplification technologies. Tripathi did not really know much about internal combustion engines, but the fundamentals and was just convinced that the control algorithms from the consumer electronics space could apply very well in the automotive engine domain. The result: a combined team of digital consumer electronics engineers and automotive powertrain controls engineers, who have made Tula’s proprietary diesel skip fire (DSF) technology a potential winner world over.

All of Tula’s early work was focussed on ICEs, particularly on spark-ignited petrol engines with an objective to derive improved fuel efficiency and CO 2 reduction. The company broadened its focus in the last few years to include diesel engines, with the primary aim to reduce emissions. The diesel dynamic skip fire (DDSF) is a result of all that effort.

Sound Generation For Enhanced Road Safety

With an ever-increasing number of fully electric and hybrid vehicles entering the market, we are witnessing a change in the acoustic experience in and around the car. The silent nature of the electric powertrain means that other road users miss the familiar acoustic cues that warn them of an approaching vehicle. To remedy this situation, Harman is working on various noise management solutions.

OBJECTIVE ASSESSMENT OF THE SAFETY CONTRIBUTION OF TODAY'S AUTOMOTIVE HEADLAMPS

Good lighting makes a major contribution to road safety. In 2011, the International Commission on Illumination (CIE) presented an evaluation system for headlamps that can objectively assess the quality of illumination and glare limitation. New light sources like LEDs and lighting functions (glare-free high beam, partial high beam) have been available for several years, so that an extension of the proven CIE method is necessary, which takes into account, among other things, changed switch-on and service lives of new lighting functions and represents a generally understandable evaluation system. An evaluation system presented in the following by the Technische Uni versität Darmstadt, which was developed by an encompassing expert commission, is intended to provide representative data and enable an objective evaluation of headlamp performance.

FUNCTIONAL SAFETY STANDARDS TOP PRIORITY FOR FUTURE AUTOMOTIVE DEPLOYMENT

Increasing levels of electronic content in vehicles result in a large amount of software that is required to run the scenes behind the mechanical aspects of a vehicle. Electronic systems in automobiles are part of every section, from the powertrain to comfort and convenience systems as well as all types of safety equipment. This makes electronics and the software running these systems a critical part of the equation for future mobility solutions. In addition, putting standards in place to measure methods of developing, testing and functioning of such electronic systems also becomes highly relevant.
