Three Way Catalytic Converter Diagram

However in some instances they may be housed separately.

Three way catalytic converter diagram. The three way catalyst helps in converting the harmful gases exhausted from the engine into harmless gases. As the exhaust gases pass through it they flow through the channels in the ceramic monolith where they encounter the particles of alumina impregnated with the metal catalysts. Working principle of 2 way and 3 way catalytic converter function of catalyst animation video catalytic converter types of catalytic converter 3 way catalytic. The catalytic converter or catcon in your car is actually a very important element of the car s exhaust system because it removes harmful nitrogen oxides no x x 1 2 3 and carbon monoxide co from the combustion residues before they are released into the environment.

The reduction and oxidation catalysts are typically contained in a common housing. Figure schematic diagram of the three way catalytic converter. The catalytic converter in a metal canister is placed in the exhaust system of the vehicle. Two way converters operate relatively efficiently with a lean fuel mixture.

Most modern cars are equipped with three way catalytic converters this refers to the three regulated emissions it helps to reduce. The reduction catalyst is the first stage of the catalytic converter. It uses platinum and rhodium to help reduce the nox emissions. Allows reduction of nox nitrogen oxides to n2 nitrogen and o2 oxygen.

The engine exhaust gases contain hazardous substances that cause damage to the environment. Catalytic converters have been used in vehicle emissions control for many years e g three way catalytic twc converters in spark ignition engines during the past several decades and docs in diesel engines since the 1990s. The last type is the three way catalytic converter. Types of catalytic converter.

Hydrocarbon no co 2 h 2 o n 2. The main drawback of lean burning is that a complex catalytic converter system is required to reduce nox emissions. Three way plus air catalytic converters. 2 h 2 2 no 2 h 2 o n 2.

As the exhaust gases pass through it they flow through the channels in the ceramic monolith where they encounter the particles of alumina impregnated with the metal catalysts. A three way catalytic converter has three simultaneous tasks. These include the oxides of nitrogen hydrocarbons and carbon. Lean burn engines do not work well with modern 3 way catalytic converter which requires a pollutant balance at the exhaust port so they can carry out oxidation and reduction reactions so most modern engines run at or near the.

Ineffectiveness in controlling nox nitrogen oxides led to the introduction of three way converters. The catalytic converter in a metal canister is placed in the exhaust system of the vehicle.
