Time to cut fumes from diesel cars
I must congratulate Anna Williams on her informed comments (Gazette 4/1/2017). It just shows how choosy and selective local politicians can be over something of public concern.
To help further the debate on the pollution issue I submit the following. All four transport fuels petrol, diesel, aviation paraffin and motorcycle two-stroke have benzene added. This when in use creates CO2 emissions (greenhouse gases).
Nitrous oxide pollution can largely be attributed to the growth of diesel emissions. There is no oxygen or nitrogen in the fuel itself. Car diesel engines with their turbos run so hot they burn the nitrogen in the air resulting in nitrous oxide (NO2). Most buses and trucks conform to legal limits, so why not cars? In cold weather this toxic level from diesel cars can go up by 11 times. Speed bumps also increase the toxic output levels.
One of the answers for reducing toxic emissions is lean burn engines. Another is for politicians to put pressure on the main culprit that being the big oil companies and the additives they put in the fuels they process. We can all blame cars and planes but big oil is the one that needs to be held to account.
