Pride of Punjab: 2 innovators to receive Clean Tech Open award for innovation to check pollution caused by vehicular emission
It is easy to imagine $7 million but to estimate and understand 7 million people is quite a task. With people are associated their aspirations contributions pleasures and relationships and their whole lives. Seven million is the population of Hyderabad or Lahore or the population of Connecticut in the US.
Clean Tech Open (CTO) in California, is a leading and prestigious organization with the mission to find, fund, and foster entrepreneurs with ideas to solve our greatest environmental and energy challenges.
CTO across America receives thousands of ideas and innovations from across the world. This year, CTO Western (California) shortlisted 1500 applications, after strict scrutiny and evaluation choose 40 applications out of which only 5 were selected to be sent forward to the Global Event to be held in San Francisco in January 2019.
The only Indian application to make it to the Final Global event was that of Adess Singh and Rajandeep Singh Tiwana, detailing a practical and ready to deploy technology, to remove the deadly particulates in exhausts from all vehicles in the world. ”
Adess Singh and Rajan Tiwana are innovators of CentriAirFlow which shall be displayed at the Global Event at San Francisco in January 2019 Adess Singh & Rajandepp Singh Tiwana are the authors of this article and national awardees for innovation.
According to a WHO report, 7 million people die prematurely every year due to air pollution. Reports have clearly attributed vehicles as the major contributors to hazardous air quality in major cities.
Transportation is unavoidable and clean air a bare and now scarce necessity
Present methods like fuel refinement, diesel particulate filters, alternate fuel vehicles etc do not resolve the problem. However, an innovation that holistically resolves the issue, does exist. In October 2018, it quietly won a runner-up prize in the regional round of Clean Tech Open, California, United States. It will be presented at the Clean Tech Open Global conference at Los Angeles, California in January 2019 as one of the global finalists. The two inventors of CentriAirFlow, the writer of this article and Rajandeep Singh Tiwana patented their product across India, USA and EU and previously won two national awards in India as well. They are now looking for partnerships with governments, companies, and organizations to push this disruptive technology ahead.
What is the problem at hand and people are royally ignorant about it
The exhaust from engines contains very fine particles of sizes ranging from 1 micron, 2.5 micron to 10 micron. (A human hair has width of 50 microns). These fine exhaust particles are coated with harmful allergens and cancer-causing chemicals called PAH (Polycyclic Aromatic Hydrocarbons). These small particulates embed themselves deep into our lungs and penetrate blood vessels causing serious health problems. PAH is present only on particulates from engine exhausts and not from residues of fire from farms, which are incorrectly blamed for the hazardous air quality in winters. The particulates from these farm fires are much larger in size and settle down.
Through current methods, govts and automobile industry are trying to resolve the issue but incompletely
Any attempt currently made to resolve the problem has addressed it incompletely. In fact, it requires either massive spends, expensive infrastructure, increased fuel cost, expensive and impractical overhaul of infrastructure or major change in consumer behaviour.
The DPF (Diesel Particulate filter) restricts the outflow of exhaust gases making the engine do more work and burn more fuel. The DPF gets choked with soot which needs to be burnt for which fuel is sprayed on it and ignited. This process is called ‘regeneration’; it does burn the soot but particles of even smaller size are generated. Also, the non-burnable or inorganic part remains and permanently chokes the DPF. The DPF needs to undergo expensive servicing and replacement even before one tenth the life of the vehicle is over. Other than this it entails multiple sensors and controls that make it very expensive.
The use of resistive filters to reduce particulates in exhaust paradoxically binds the industry into a negative inverse relationship between particulate emission, emission of NOx and CO. Using presently available resistive filters any attempt to reduce particulates, leads to an increase in emission of NOx and CO and fuel consumption. This is because resistive filters load the engine.

Thus mere availability of Bharat Stage VI fuel shall have no effect on pollution as it will be mostly used by vehicles of Bharat Stage III or IV
Billions of dollars are spent on refinery upgrade to produce greener and cleaner fuel. While in itself, this is a laudable effort its effect is marginalized by the sheer number of vehicles currently in use. Worldwide there are over 1.2 Billion 4 wheeled (and heavier) on road-vehicles, to which 260,000 are added every day.
These vehicles have a legal service live of about 15 years. Thus the mere availability of Bharat Stage VI fuel shall have no effect on pollution as it will be mostly used by vehicles of Bharat Stage III or IV.
When electricity generation is itself not green, electric vehicles too cannot be considered green
It is only natural in the above situation to grab at straws, the world’s reaction towards electric vehicles sums this up perfectly. When electricity generation is itself not green, electric vehicles too cannot be considered green. Both in the United States and in India the greenhouse gas emission for every kilowatt of electricity produced is exactly equal to the emissions for the same amount of energy produced from internal combustion engines. The same is true in China.
Changing the way electricity is produced is too far away to be considered in the present situation. The pie charts below make this important realization clear. Additionally, electric cars will require a major change in infrastructure at national, manufacturer and consumer levels.
The Solution – CentriAirFlow:
The innovation eliminates particulate release into environment & reduces back pressure, to increase engine efficiency by 12-15% thus saves the end-user on fuel
Today’s reality is that fossil fuels, despite their ill effects, are still the most efficient and easily available source of energy. This situation, by most estimates, will not change for the next 20-40 years.
A practical solution to mitigate the effects of fossil fuels must be easily implementable, save money for all stake-holders, need no expensive and time-consuming infrastructure, need no change in consumer behaviour and be usable by all internal combustion engines irrespective of vintage or type of fuel used.
CentriAirFlow provides all these advantages. It uses speeds available to exhaust gases to separate and entrap up to 95% of particulates including those less than 1 micron in size. It achieves this without increasing back-pressure (resistance) on the engine. In fact, the clever design reduces back pressure, to increase engine efficiency by 12-15% and thus save the end user money on fuel. Initial tests of the technology brought forth
additional benefits of reducing release of NOx, CO and reducing exhaust noise.
CentriFlow retrofits the existing 1.2 billion on-road vehicles irrespective of vintage or type of fuel used
It reduces emission of particulate matter by over 95%. CentreAirFlow also increases engine efficiency, retro-fits all engines. This is irrespective of vintage of the engine or type of fuel used (like diesel, petrol, CNG, biogas etc.) And it works with all internal combustion engines (vehicles, ships, furnaces, generators, heavy-duty vehicles, farm equipment, construction equipment etc.) Proof of concept stage testing, was conducted on a 3 litre diesel vehicle at ICAT Maneser (New Delhi), through an initial grant from Government of India.
The tests clearly proved the claims and showed that entrapment of particles including those smaller than 1 micron size, besides reducing NOx & CO and significantly improving fuel efficiency.
Viewing through powerful microscopes it is clear that CentriAirflow actually separates and entraps particulates of even less than 1 micron size.
CentriAirFlow—A WIN WIN Innovation
CentriAirFlow has the ready ability to positively impact health of all living beings.
CentriAirFlow will provide respite to governments in dealing with the embarrassing situation of toxic air in cities. It will enable manufacturers to use their current infrastructure without major changes. It will also enable consumers to continue using their cars at lesser fuel costs and drive green. If clean air is what you want immediately, this is an innovation you should demand from your governments and car companies.
