Hey friends,

I have just read a news in local news paper which says, CPCB(central pollution control board) recommend the government to ban the personal diesel vehicle usage in Delhi to control the pollution in capital. It also says any other state personal diesel vehicles also should not be allowed to enter into Delhi [surprise]

Source : Andhrajyothy daily news

Mods,

Change the title to "Ban on personal diesel vehicles in Delhi - CPCB recommends to Govt."

If they do something like this, then people will in & around delhi will have to switch to CNG/Petrol cars back.

There is always two sides of the story. Petrol vehicles without catalytic converter are more polluting than diesel. With converter though, the diesel is more polluting.

If this regulation is introduced, what would be the value of Bharat4/3 then?

On a separate note, think electric vehicles are pollution free? Think again - Study shows impact of electric cars is worse than petrol-powered vehicles | Mail Online

This is just another tantrum from non working babus of our country to show that they care for environment and all that jazz. Eventually, like all other initiatives from them, nothing will happen.

Re: Ban Personal Diesel Vehicles in Delhi - CPCB Recommends To Govt.

these are just implemented on papers and nothing is done for real.

why don't they ban all the goverment's trucks and jeeps which are just rotting for years but still are under usage.

pollution level will come down.

What is wrong with diesel .... anybody?[surprise]
Diesel cars have very different emission characteristics, and an increase in diesel cars at the expense of petrol cars could have important implications on air quality, smog formation, global warming and other environmental issues probably. Emissions of lead are falling due to the banning of leaded fuel in most of the countries

when compared to petrol cars with a catalyst, diesels have higher emissions of NOx [roll]

Something out of the point :

Leaving all emission aspects, a diesel engine is more better than petrol engine because diesel engine has the maximum efficiency than petrol engine. also diesel engine can handle more load than petrol,as we can see in case in case of heavy vehicles.

And moreover there is no Ignition Circuit to fail on a diesel engine. The ignition is achieved by compression and a "glow plug" which remains heated between piston cycles.

Heart always tells diesel when we are so addicted to torque [evil]

That was really enlightening, Thanks "swift&furious".

Which petrol cars dont come with Catalytic converter? My 96' M800 has it, so are we referring to older cars?

Re: Ban Personal Diesel Vehicles in Delhi - CPCB Recommends To Govt.

It's the onset of winter and Delhi is notorious for it's fog / smog problem. The decision might have been made in this context. If that is indeed the case, what about those trucks? A very difficult decision to implement though.

Found an interesting article:

Since 2000, the levels of two key pollutants have risen sharply in Delhi's air — respirable particulate matter (PM10) has gone up by 47% and nitrogen oxides (NOx) by 57%. Both are higher than safe levels and pose a danger to public health. They're linked to respiratory diseases and, in the case of NOx, aggravation of heart ailments. Both are emitted mainly in diesel fumes.

Reason, the Supreme Court asked for the government's view on a proposal to tax diesel cars at the rate of 25% as a possible means of curbing Delhi's pollution. Carmakers oppose the proposal insisting diesel isn't used just to run cars. Generator sets, pumps to irrigate fields use diesel. Industrial pollution and the construction boom play a role.

Environmentalists agree there are multiple sources of diesel emissions and all need to be tackled. But, they say, private diesel cars are a major source. The rise in PM10 and NOx levels corresponds with the growth of diesel vehicles in Delhi. The share of diesel vehicles in the Capital's car sales has risen from 4-5 % in 2000 to almost 60% today, driven by the widening petrol-diesel price gap.

But as the number of private diesel vehicles has grown, so has the myth that modern diesel technology has made the fuel clean. Experts say that's hardly true in India. "The BharatIV norms are in force in 20 cities (including Delhi). These are 12 years behind Europe's current norms," Anumita Roychowdhury, who tracks air pollution at the Centre for Science and Environment, says. She has a point. NOx emission values of diesel in Bharat IV remain almost three times higher than that of petrol. Diesel norms allow significant amounts of PM while these emissions are close to zero in petrol. That apart, diesel fumes contain another class of carcinogens called polycyclic aromatic hydrocarbons (PAHs).

Earlier this year, WHO reclassified diesel exhaust as a class 1 carcinogen, placing it in the same toxic bracket as tobacco smoke. A recent AIIMS study found growing incidence of lung cancer among non-smokers in Delhi. "Exposure to diesel exhaust fumes certainly appears to be one of the factors behind this rise," Dr Randeep Guleria, professor and HoD, pulmonary medicine at AIIMS, said.

Here is the counter argument by the auto maker's on the above article

Is diesel really dirty? Is slapping a green tax on vehicles that run on the fuel the right way to control air pollution and smog in and around the national capital?

It's true pollution and smog levels are on the rise. But the solution to these problems don't necessarily lie in taxing diesel cars higher, auto industry players say. Policy planners will need to look at other contributors, including use of diesel generator sets and the construction boom.

A recent Central Pollution Control Board (CPCB) study throws up important findings. Vehicles, it says, contribute 6.6% to particulate emissions (PM) in Delhi. Road dust is the biggest contributor at 52.5%. Industries around Delhi and in neighbouring states account for as much as 22% of particulate emissions, while 19% is because of its geography.

The Society of Indian Automobile Manufacturers (Siam), a lobby group for automakers, cites this CPCB report and adds personal vehicles constitute an even smaller proportion of the overall vehicles category. "Diesel technology in cars and SUVs is clean and fuel-efficient . Most of the PM discharge attributed to vehicles is from old trucks that enter Delhi. They run on outdated engines," Vishnu Mathur, Siam DG, says.

Siam talks of an "urgent need" to modernise commercial vehicles and wants quick implementation of stringent Bharat Stage IV (BSIV) norms across the country. "We have BSIV in 20 cities. The next phase of expansion is in 2015, when 50 more cities will be upgraded," Mathur says.

The story in Europe, where diesel is the preferred fuel, is an eye-opener . The diesel Europeans use is super refined, often considered greener than petrol. Importantly, in the continent, diesel cars must conform to Euro V emission standards . In India, we are way behind at BS IV. Carmakers insist they can introduce more efficient car engines once the government raises the bar and implements tougher emission standards. The need of the hour, they say, is a clear roadmap.

When BSIII norms were in force in India, the permissible particulate matter discharge was 0.05 grams/km for diesel cars. It's fallen to 0.025 grams/km under BSIV. Emission levels of carbon monoxide, hydrocarbons and nitrogen oxide have come down in the BSIV regime . "Why are we taking so long for the full BSIV rollout when the norms will lead to improvement in engine quality and cut emissions," Mathur asks.

Siam dismisses suggestions that Delhi's worsening air quality is because of the rise in diesel car numbers. "It's a wrong argument. The same norms and technology existed in Europe till 2005. They didn't have the kind of smog we do."

Yes, true indeed, and what about the tourists UVs that throw out black smoke even when they are driven normally? Private passenger cars are the most maintained of all the diesel cars/UVs/Trucks. Why not just scrap the 10/15 years old truck, so that pollution can be controlled. They just want to earn money by puttng more and more burden on common man's shoulder in the name of tax. And where does tax goes? under table. Few more farm houses and buildings will be developed in few years. [anger]
