Diesel exhaust is the exhaust gas produced by a diesel engine, plus any contained particulates. Its composition may vary with the fuel type, rate of consumption or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator ...
Cars produce numerous harmful air pollutants in their exhaust such as NO x, particulate matter and ground-level ozone (indirectly). [9] Additionally, as car tires wear down, they shed the materials they are made of into the air as particulate pollution. [ 10 ]
A study just published in an American Heart Association journal links atherosclerosis -- hardening of the arteries -- to car exhaust. The diesel exhaust fumes robbed what is generally known as ...

Idling automobiles with the exhaust pipe blocked by snow has led to the poisoning of car occupants. [83] Any perforation between the exhaust manifold and shroud can result in exhaust gases reaching the cabin. Generators and propulsion engines on boats, notably houseboats, have resulted in fatal carbon monoxide exposures. [84] [85]
In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO x) emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. [1] EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders .
