2LITERATURE REVIEWDurairajan A et.al. conducted an Experimental investigation and control the toxic emissions in IC engines by nano materialsInvestigational Study and Manage the Poisonous Emissions in IC Engines by Nano Materials by N.Kanthavelkumaran et.al.

3INTRODUCTIONAll transport vehicles; both SI (Spark ignition) and CI (Compression ignition) are equally responsible for emitting different kind of pollutants Some of the primary kinds having direct hazardous effects such as carbon-monoxide, hydrocarbons, nitrogen oxides, etc

4 Carbon-dioxide is not considered as pollutant. If carbon-dioxide exceeds 5000ppm, then it becomes a health hazard. Using nano catalytic converter, pollution is controlled by means of catalytic reaction

5METHODOLOGY1. Laser ablation2. Arc discharge3. Plasma enhanced CVD4.Chemical vapor deposition (CVD) CVD method is used to synthesis the Nano palladium & Nano rhodium

6CHEMICAL VAPOR DEPOSITION (CVD)7

8CATALYTIC CONVERTOR9

Reduce the toxicity of emissions from an internal combustion engine.Converts the harmful toxic combustion products and its byproducts into less-toxic substances.Catalysis

10Effective after treatment process for reducing engine emissionCatalytic converter is generally called as three way catalytic converterHoneycomb structureCatalytic converter uses alumina

11TYPES OF CONVERTORS Monolythic Convertor

Two way Convertor

Three way Convertor

Dual bed Convertor

12GENERAL PRINCIPLES OF CATALYSISThe following is a typical reaction, where C represents the catalyst, X and Y are reactants, and Z is the product of the reaction of X and Y. X + C XC Y + XC XYC XYC CZ CZ C + Z

16RESULTSNOx Reduction

17

The NOx value decreasing and reaches the minimum value on using nano catalytic converter. Catalytic reaction with Nano palladium No load condition 33.33% decrease in NOx value At peak load condition about 54.3 % NOx value.18HC Reduction

19

The HC value decreases to minimum value on using Nano catalytic converter.

Catalytic reaction with nano rhodium

At no load condition about 72.1% decrease in HC value At peak load condition about 68.8 % decrease in HC value.

20CO Reduction

21

The CO value decreases and reaches the minimum value on Nano catalytic converter.

Catalytic reaction with nano rhodium

At no load condition there is about 60% decrease in CO value At peak load condition there is about 40 %

22CONCLUSIONNano palladium and nano rhodium particles (90-100 nm) were synthesized and characterized byusing chemical vapor deposition method.

The nano catalytic converter efficiently decreases the emission of NOx, HC and CO components.

Only one factor disqualify nano catalytic covertor is the cost
