High temp. in combustion chamber possibly caused by malfunction in EGR system.

The oxides of nitrogen dissolve in rain water to form nitrous and and nitric acid which cause acid rain.

Photochemical smog. The brown color is cause by the presence of a various Nitrous Oxides. Saludos. :-)

When the engine of a vehicle consumes fuel and air to generate energy, the vehicle cannot retain the products of combustion; it would be too inefficient and expensive. The vehicle discharges those waste elements in the exhaust system. The exhaust gases are carbon dioxide, carbon monoxide, nitrous oxides, water vapor and soot.

Yes.Carbon dioxide causes global warming.Nitrous and Sulphur oxides cause acid rain.

Answer:The release of Carbon Dioxide into the atmosphere which is causing global warming and climate change.The release of Nitrous and Sulphur oxides and other polluting gases which cause acid rain.

The EGR valve may not be functioning correctly allowing too much oxygen to enter into the combustion process. If someone has rebuilt the engine the compression could be at a high enough level that increased levels of oxides of Nitrogen could be produced. Note that high compression and faulty EGR valves that allow too much oxygen both cause the combustion temperature to run higher than designed. High compustion temperatures are the ultimate cause of elevated levels of oxides of Nitrogen. *Engine could also be running too hot and casusing incresed combustion temperatures causing increased oxides of nitrogen

Nitrogen Oxides are reactive. General name NOx refer to NO and NO2. They react and cause respiratory system damage.Example reaction of NO2 is as follow.2 NO2 + H2O โ†’ HNO2 + HNO3Nitric acid and nitrous acid are formed with presence of moisture in air and in the lungs. This is highly corrosive to the pulmonary system in the body.

Yes! Nitrogen oxides are toxic colorless gases found in cigarette smoke, vehicle exhaust, burning wood, etc. Inhaling these gases can cause shortness of breath, nausea, fluid build-up in lungs (pulmonary edema) and respiratory airway damage.

There are many things that could cause your exhaust temperature to be high. Your exhaust may be plugged for example.

In controlled amounts(like at the dentist's office), nitrous oxide can cause you to feel drowsy. Or, if you have a reaction to it, it can cause you to laugh hysterically. Hence the name, "laughing gas"

Not directly. The oxygen sensor measures oxygen levels in the exhaust. The computer uses that to calculate fuel and spark timing. If an oxygen sensor is malfunctioning, it could cause idle problems.Not directly. The oxygen sensor measures oxygen levels in the exhaust. The computer uses that to calculate fuel and spark timing.

can exhaust manifold leak cause you to burn oil

A customer's auto is producing blue exhaust. What could cause this

User Avatar

No, it will not cause smoke from the exhaust pipe. However the leaking oil can drip on the exhaust manifold where it will be burnt and smoke.

Substances made of oxygen and sulfur.

The burning of coal that contains a lot of sulfur.

User Avatar

If you mean atmospheric pollution from burning hydrocarbon fuels, the main ones are Carbon Dioxide, Nitrous Oxide and Sulphur Dioxide. All fuels produce CO2 and water-vapour. Nitrous Oxide is a by-product in petrol- and diesel- engine exhaust. The SO2 comes mainly from sulphur-rich coal; but the amount varies a lot with the quality of the coal used.

Volcanoes cause acid rain because the gas bubbles built up in the molten rock are released and go into the air which can sometimes cause acid rain, the sulfur dioxide and nitrous oxides are burnt and these react with the water in the atmosphere, sulfuric and nitric acids are produced and the rain will have a lower pH level making it acidic to make acidic rain.

User Avatar

No. Acid rain is the result of nitrogen oxides and sulfur oxides put into the atmosphere by volcanoes and the burning of fossil fuels.

The cause of an exhaust indicator light in a Volkswagen Beetle is probably an oxygen sensor. There also a possibility that an exhaust pipe is plugged or there is a hole due to rust.

Exhaust gasses are escaping through a hole or rotted section of exhaust system
