EXHAUST: Describes the system to disperse spent fuel in an internal combustion engine.
EXHAUST BACK PRESSURE: Describes any pressure holding back the flow of the gases in an exhaust system.
EXHAUST BACK PRESSURE TRANSDUCER VALVE(BPV): Describes a device that senses changes in an exhaust system and will control the build-up of vacuums in response to these changes
EXHAUST CAMSHAFT: Describes a separate camshaft whose role it is to control the opening and closing of the exhaust valves used in twin overhead camshaft engines
EXHAUST CHAMBER: Describes part of the two-stroke exhaust system designed to maintain a specified back pressure
EXHAUST CUTOUT: Describes a Y-shaped device placed in the exhaust pipe ahead of the muffler. The vehicle can then channel the exhaust through the muffler or out the other leg of the "Y", where the exhaust passes out by bypassing the muffler.
EXHAUST DOUGHNUTS: Describes the small rubber connectors used to suspend the exhaust system from the chassis pan
EXHAUST EMISSION CONTROL SYSTEM: Describes the general term for any system used to reduce harmful exhaust emissions in a motor vehicle.
EXHAUST EMISSIONS: Describes the unburned hydrocarbons, carbon monoxide, oxides of nitrogen, and other toxic gases emitted when gasoline is burned in an engine.
EXHAUST GAS: Describes gas which is the product of the combustion process passed out of the cylinder through the exhaust valve or port into the exhaust system.
EXHAUST GAS ANALYSER: Describes an instrument designed to determine an engine's efficiency levels to determine both combustion efficiency and the number of pollutants in the exhaust.
EXHAUST GAS CHECK VALVE(EGC): Describes a device that allows air in an injection system to enter the exhaust manifold while preventing a reverse flow in the event of irregular operation in other components
EXHAUST GAS OXYGEN SENSOR(EGO): Describes a device that changes its output voltage as the exhaust gas oxygen content changes when compared to the oxygen content inf the atmosphere. This constantly evolving voltage signal is sent to the processor for analysis and adjustment to the air/fuel ratio
EXHAUST GAS PURIFICATION SYSTEM: Describes an exhaust emission control system for diesel engines, which typically consists of an exhaust scrubber, diesel exhaust filter, and a catalytic converter
EXHAUST-GAS RECIRCULATION(EGR): Describes an emission control system where some of the exhaust gases generated are rerouted from the exhaust manifold into the combustion chamber to ensure that all fuel is burned before entering the atmosphere.
EXHAUST HEADER: Describes the steel tubing connecting pipes situated between the exhaust ports and the exhaust pipe.
EXHAUST HEAT CONTROL VALVE(HCV): Describes a valve whose role is to reroute hot exhaust gases to the intake manifold heat riser during cold engine operation. HCVs can be thermostatically, or computer-controlled, or vacuum operated.
EXHAUST MANIFOLD: Describes the connecting pipes between the exhaust ports of each cylinder and the exhaust pipe, usually made of cast iron or steel tubing.
EXHAUST OXYGEN SENSOR: Describes a device designed to detect levels of oxygen within the exhaust stream.
EXHAUST PIPE: Describes the pipe that connects the exhaust manifold to the muffler.
EXHAUST PORT: Describes the passage in the cylinder head that connects the exhaust valve and the exhaust manifold.
EXHAUST PRESSURE REGULATOR(EPR): Describes a device used to increase exhaust backpressure at specific times,
EXHAUST STROKE: Describes the fourth stroke of a four-stroke cycle in which the piston moves upward from bottom dead centre to top dead centre and pushes the burned exhaust gases out of the cylinder.
EXHAUST SYSTEM: Describes the pipes, resonators and mufflers that combine to carry the exhaust gases from the exhaust manifold into the atmosphere.
EXHAUST TREATMENT: Describes any measures taken to reduce pollutant concentrations in an internal combustion engine's exhaust before they are released into the atmosphere
EXHAUST VALVE: Describes the valve through which the burned fuel charge passes on its way from the cylinder to the exhaust manifold, driven by the camshaft.
