None its only used when the car is moving
It releases gasses that facilitates the greenhouse effect into the atmosphere.
The reason why Car exhaust is bad for the planet is Because, The exhaust gases Become trapped in the atmosphere. They then trap heat from the sun like a greenhouse(hence the greenhouse effect), and Mess up the ecosystem.
The motor in your car does not burn the fuel completely, and what is left over is excreted into the atmosphere.
It varies by car, year and engine.
By emitting Carbon Monoxide, Carbon Dioxide, Nitrogen Oxides, and Hydrocarbons.
The internal combustion engine, especially the gasoline type, is not very efficient. The exhaust gases leaving the cylinder on the exhaust stroke are still very hot, and therefore take a lot of heat with them. In a car this is just rejected to the atmosphere via the exhaust system. In addition the engine must be cooled to avoid damage to the cylinder head and block, and this loses heat via the car's radiator to the atmosphere.
by littering By polluting the atmosphere with car exhaust and industrial byproducts such as CO2, CO and methane (among worse things).
anywhere from $20 to $1500
It can. Backfires are caused by raw fuel in the exhaust pipe and lit off by hot gases from the cylinders. If enough fuel enters the exhaust system and the muffler or catalytic converter, it can cause enough pressure once lit to split pipes and mufflers.
if it runs on pure hydrogen then the only exhaust will be pure water vapor.
Carbon Monoxide and Carbon Dioxide are contained in car exhaust fumes. Carbon Monoxide is a toxic gas that if too much is breathed in, you die.
from the car exhaus or in the car exhaust?.... if u have oil in ur exhaust that's not good..lol from the outside of the exhaus just use degresser doesnt cost much... and if u don't wanna buy that just use fuel
