Compared to heavy industry, no. Compared to gas, propane, etc, engines, yes.
The draw back from using diesel engines is they put out the most "Heavy" particulates then a gas engine. ALL vehicles have soot/heavy particulates.
With the newer diesels it has become less of a problem. The upside of running a diesel is you get more power/torque from a diesel then a gasoline engine. More bang for your buck.
A running Diesel engine releases soot in its exhaust. Another word for soot is particulate pollution - as soot consists of small particles.
Mostly un-burned carbon in the form of a fine soot.
If the engine is diesel, no that is normal. If the engine is gasoline, yes it is probably burning oil.
A diesel particulate filter, sometimes called a DPF, is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine.
There is not a whole lot of difference if you are using the oil in an older diesel engine. The diesel oil of today has special additives to combat the soot buildup in the oil from the EGR. The diesel oil will get dirty a lot sooner on the late model engines. A 15w40 for a gas engine can be used in a diesel.
Soot particles are the result of incomplete combustion of carbon or organic compounds.
Of an individual diesel engine and an individual steam engine of the same energy output the diesel engine would be less polluting. It is far more efficient. However, there are far more diesel engines than steam engines in the world today so overall diesel engines pollute more than steam engines.

Only on cars equipped with diesel engines. Diesel catalytic converter is equipped with a DPF or Soot Trap. All diesel engine powered vehicles built after 1/2007 must be equipped with a Diesel Particulate Filter (DPF). As the amount of soot trapped on the DPF increases, so does the back pressure in the exhaust system. Periodic regenerations (high temperature excursions) are required to initiate combustion of the trapped soot and thereby reducing the exhaust back pressure. The amount of soot loaded on the DPF prior to regeneration may also be limited to prevent extreme exotherms from damaging the trap during regeneration.
The present invention relates to a soot afterburner for amotor vehicle exhaust system. More particularly this invention concerns an electrically powered device that burns soot separated out of the exhaust gas stream of, for instance, a diesel engine.
Diesel, if you can believe it, with all the soot it makes... Diesel has a significantly lower number of certain carbons in it that harm the environment.
Modern Diesel cars often have a diesel particle filter (DPF) installed in the exhaust to trap fine soot particles and stop them getting into the athmosphere.
