None its only used when the car is moving
It varies by car, year and engine.
The motor in your car does not burn the fuel completely, and what is left over is excreted into the atmosphere.
By emitting Carbon Monoxide, Carbon Dioxide, Nitrogen Oxides, and Hydrocarbons.
Exhaust fumes from cars are an example of air pollution. They contain harmful gases and particulate matter that are released into the atmosphere, contributing to environmental and health issues.
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.

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.
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).
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.
