I've been doing a lot of reading up on this recently (as have just ordered a new car) and have come to the conclusion: Diesel is better for the environment than Petrol as it emits lower co2 but the nox emissions (which effects human health) are higher (although not much in it). Based on this the diesel is better in the countryside as the nox gases can disperse better but if you are living in the city then petrol it is. Sound correct?
no PM10 (particulate material <10mu??? thought problem with Diesels?) hey; CAM we still friends aren't we?
particulate carbon less than 10 microns absolute, the black dusty stuff in the tailpipe, apparently causes lung cancer when it gets stuck in your lungs,? this applies to trucks? dont ask Audi and VW? they might not tell the truth, lol; maybe they tell the truth? Maybe current emissions systems got rid of the PM10mu s? 1) reference to VW and Audi and have misrepresented emissions in their product leaflets; where you are getting your information from? I will help you; Audi and VW have fabricated/manipulated emissions test results that have made them liable for hundreds of class action suites from consumers and massive penalties from the relevant environmental agencies in the product's destination markets. BERLIN (Reuters) - Audi’s (NSUG.DE) emissions scandal flared up again on Thursday after the German government accused the carmaker of cheating emissions tests with its top-end models, the first time Audi has been accused of such wrongdoing in its home country. The German Transport Ministry said it has asked Volkswagen’s (VOWG_p.DE) luxury division to recall around 24,000 A7 and A8 models built between 2009 and 2013, about half of which were sold in Germany. VW Chief Executive Matthias Mueller was summoned to the Berlin-based ministry on Thursday, a ministry spokesman said, without elaborating. VW didn’t return calls seeking comment. The affected Audi models with so-called Euro-5 emission standards emit about twice the legal limit of nitrogen oxides when the steering wheel is turned more than 15 degrees, the ministry said. It is also the first time that Audi’s top-of-the-line A8 saloon has been implicated in emissions cheating. VW has said to date that the emissions-control software found in its rigged EA 189 diesel engine does not violate European law. 2) Health Impacts of Diesel Pollution Diesel-powered vehicles and equipment account for nearly half of all nitrogen oxides (NOx) and more than two-thirds of all particulate matter (PM) emissions from US transportation sources. Particulate matter or soot is created during the incomplete combustion of diesel fuel. Its composition often includes hundreds of chemical elements, including sulfates, ammonium, nitrates, elemental carbon, condensed organic compounds, and even carcinogenic compounds and heavy metals such as arsenic, selenium, cadmium and zinc.¹ Though just a fraction of the width of a human hair, particulate matter varies in size from coarse particulates (less than 10 microns in diameter) to fine particulates (less than 2.5 microns) to ultrafine particulates (less than 0.1 microns). Ultrafine particulates, which are small enough to penetrate the cells of the lungs, make up 80-95% of diesel soot pollution. Particulate matter irritates the eyes, nose, throat, and lungs, contributing to respiratory and cardiovascular illnesses and even premature death. Although everyone is susceptible to diesel soot pollution, children, the elderly, and individuals with preexisting respiratory conditions are the most vulnerable. Researchers estimate that, nationwide, tens of thousands of people die prematurely each year as a result of particulate pollution. Diesel engines contribute to the problem by releasing particulates directly into the air and by emitting nitrogen oxides and sulfur oxides, which transform into "secondary" particulates in the atmosphere. Diesel emissions of nitrogen oxides contribute to the formation of ground level ozone, which irritates the respiratory system, causing coughing, choking, and reduced lung capacity. Ground level ozone pollution, formed when nitrogen oxides and hydrocarbon emissions combine in the presence of sunlight, presents a hazard for both healthy adults and individuals suffering from respiratory problems. Urban ozone pollution has been linked to increased hospital admissions for respiratory problems such as asthma, even at levels below the federal standards for ozone. Diesel exhaust has been classified a potential human carcinogen by the U.S. Environmental Protection Agency (EPA) and the International Agency for Research on Cancer. Exposure to high levels of diesel exhaust has been shown to cause lung tumors in rats, and studies of humans routinely exposed to diesel fumes indicate a greater risk of lung cancer. For example, occupational health studies of railroad, dock, trucking, and bus garage workers exposed to high levels of diesel exhaust over many years consistently demonstrate a 20 to 50 percent increase in the risk of lung cancer or mortality.² the question marks ??? are only included because I worry you even addressed the primary questions? That appears to show you never research the answers on the internet, yes you fail tell me something I don't know, rather then criticize my economic use of grammar? good show old boy, good show?
No, me too. It's just gobbledy gook with question marks thrown around like confetti. I find it quite annoying to be honest.
Agreed I is ???? Flying carpets??? Leather chaps???? Nuclear bicycle chain????? Carbon carpet slippers u think????? Sofa diesel chlorine???? Are we still friends pavey ???
I agree with the conclusion, assuming you are doing high(ish) miles in the countryside to justify the higher purchase price of the diesel. However. Would a marginal reduction in CO2 emissions from diesel compared to petrol be significantly better for the environment ? Is scrapping usable diesel cars and replacing them prematurely with new cars good for the environment ? As usual I just don't think it is a simple as they make out.
Wayne/Pavey just trying to save you from dying in a stink box, from large things growing inside you? no not aliens?
Fantastic idea, and we could all buy a diesel generator to recharge the batteries because the national grid will not have enough capacity Best of all the diesel generators can run on red diesel and it will save everybody money because there is no road tax on red diesel Back to reality electric cars are part of the problem not part of the solution, we need to get people out of cars and onto a properly integrated public transport system
We'll all be back on pack horses if the state if the roads continue to deteriorate like they are, as they'll be the only mode of transport that'll be able to tackle the potholed terrain!
You can bugger off with ya public transport idea!! Love my cars and bikes far too much for all that sitting on a crowded bus malarkey
