A three-way catalytic converter on a gasoline-powered 1996 Dodge Ram Simulation of flow inside a catalytic converter. A catalytic converter is an exhaust emission control device which converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction.
Diesel exhaust is the exhaust gas produced by a diesel engine, plus any contained particulates. Its composition may vary with the fuel type, rate of consumption or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator ...
It is one of the three major components for proper engine operation: the computer, electrically controlled carburetor, and the oxygen sensor in the exhaust system. [ 2 ] Starting with the 1986 model year, the AMC straight-4 engines used a throttle body injection (TBI) or single-point , fuel injection system with a new fully computerized engine ...
Heat from the exhaust is used to warm the intake manifold and in turn the carburetor. On V configurations, exhaust gases were directed from one head through the intake cross over to the other head. One method for regulating the exhaust flow on the cross over for intake warming was a weighted eccentric butterfly valve called a heat riser that ...
Fuel-saving devices are sold on the aftermarket with claims they may improve the fuel economy, the exhaust emissions, or optimize ignition, air flow, or fuel flow of automobiles in some way. An early example of such a device sold with difficult-to-justify claims is the 200 mpg ‑US (1.2 L/100 km) carburetor designed by Canadian inventor ...
The draught tube routes all blow-by gases back into the intake mixture and is usually located between the air filter and carburetor. Dry sump engines in some drag racing cars use scavenging pumps to extract oil and gases from the crankcase. [18] A separator removes the oil, then the gases are fed into the exhaust system via a venturi tube.
In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO x) emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. [1] EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders .
Vehicle emissions control is the study of reducing the emissions produced by motor vehicles, especially internal combustion engines.The primary emissions studied include hydrocarbons, volatile organic compounds, carbon monoxide, carbon dioxide, nitrogen oxides, particulate matter, and sulfur oxides.
