People commonly refer to exhaust gas as exhaust emissions, which typically originate from the exhaust pipes of cars and other vehicles that run on gasoline or diesel fuel. The exact composition can vary significantly depending on whether it is unburned hydrocarbons or products of partial combustion of air-fuel mixtures that have leaked through seals in engine cylinders and valves and escaped directly into the atmosphere rather than passing through the vehicle's catalytic converter for processing and cleanup before they're released outside into ambient air where humans inhale every time.
