  • Preventing Catalytic Converter Thefts
    Ty Henshaw, Chief of Police IRWINDALE POLICE DEPARTMENT Preventing Catalytic Converter Thefts Catalytic converter thefts from vehicle exhaust systems continue to increase throughout the region. A catalytic converter is part of your car's exhaust system and is used to convert dangerous exhaust pollutants into less harmful emissions as they pass through your car's exhaust pipe. Catalytic converters have been required on all cars sold in the U.S since 1975. They don't seem very glamorous, but they are extremely attractive to thieves. The reason lies in the value of the metals used in the manufacturing of the converters. Catalytic converters contain platinum, rhodium, and palladium and their value to thieves across the nation has increased dramatically in recent years due to the black market resale value of these metals. Catalytic converters are relatively easy to steal and a skilled crook can remove one from a car in just a few minutes. Because they are concealed underneath the car, many owners do not even know their converter has been stolen until they notice the car running poorly and they hear a loud, rumbling exhaust noise. If you believe your car’s catalytic converter has been stolen, look under the car. The catalytic converter is a round canister that connects two pieces of the exhaust piping that runs from your engine to your tail pipe. If your converter has been taken, you'll see a gap or open space in the middle of the exhaust and you'll likely see evidence of the exhaust piping being cut away. Not only does the theft of a catalytic converter result in a poorly running vehicle, but it is also illegal to drive your car without one.

  • The Influence of the Exhaust System Leak on the Operating Parameters of a Turbocharged Spark Ignition Engine
    I Eksploatacja i testy Krystian HENNEK, Mariusz GRABA THE INFLUENCE OF THE EXHAUST SYSTEM LEAK ON THE OPERATING PARAMETERS OF A TURBOCHARGED SPARK IGNITION ENGINE Turbocharging of an internal combustion engine is the most common technique to improve an engines’ performance. In present it is not hard to meet vehicles on the road with turbocharged SI engines, which have a high mileage, and because of this fact there is a high risk of exhaust systems leak. This might have its influence not only on the emissions, but also on the vehicles performance. Thereby this dissertation shows the comparative analysis of the influence of exhaust system leak in the catalyzer input on the exhaust gasses composition in the catalyzer output and the operation parameters of an turbocharged SI engine. During the research some parameters were recorded and compared, e. g.: the engines power and torque, the injectors opening time, the oxygen sensors voltage signals in the input and in the output of the catalyzer, the concentration of harmful gasses in the exhaust tailpipe. The research was conducted with the use of a single roller MAHA MSR 500 chassis dynamome- ter. A series of torque measurements was performed. Under these measurements a simulation of the exhaust system leakage of a turbocharged SI passenger car engine was made. As a result three variations of the wideband oxygen sensor acting were reached. The wideband sensor is mounted between the turbocharger unit and the input of the catalyzer. In the test the influence of the leakage on the injector’s opening time and the composition of harmful exhaust substances were pointed.

  • Clean Air Facts
    CClleeaann AAiirr FFaaccttss The Catalytic Converter: Technology for Clean Air Overview The catalytic converter has been the centerpiece of mobile source emission control throughout the world. Since the mid-1970s, catalysts equipped on passenger cars, from the first two-way oxidation catalysts to today's advanced three-way catalysts, have cut pollution by more than 10 billion tons in the U.S. Catalyst technology frequently has been hailed as one of the great automotive engineering achievements. Catalytic converters have been developed for use on trucks, buses, and motorcycles, as well as on construction equipment, lawn and garden equipment, and other non-road engines. The technology has been used on vehicles and equipment fueled with gasoline, diesel, propane, and natural gas. The History of the Automotive Catalyst • When strict vehicle emission standards were first set in the Clean Air Act Amendments of 1970, automakers did not possess the technology to significantly lower vehicle emissions. Catalytic converters for automobiles were developed to meet the standards set by the U.S. Congress. • Catalytic converters, or “catalysts,” were first installed on cars in the mid-1970s. • Over the past 30 years, catalyst technology has continued to advance to meet increasingly tighter emissions standards and greater durability requirements. How a Catalytic Converter Works • First generation catalytic converters, called “two-way converters,” only controlled carbon monoxide (CO) and hydrocarbon (HC) emissions. • In the early 1980s, catalysts were introduced that could control nitrogen oxides (NOx), in addition to controlling CO and HC. All cars sold in the U.S. today are equipped with this type of catalytic converter, called a three-way converter.

  • Decomposition of N2O Over Ru/Fe/Al2o3 Catalyst Nanoparticles Gaston O
    Decomposition of N2O over Ru/Fe/Al2O3 catalyst nanoparticles Gaston O. Larrazabal Particle Technology Laboratory, Department of Mechanical and Process Engineering, ETH Zurich, 8092 Zurich, Switzerland Report handed in on December 23, 2011 Supervisor: Dr. Robert Büchel Abstract. As the third-largest greenhouse gas and the most important ozone-depleting substance, nitrous oxide (N2O) represents a significant environmental issue. In this work, the catalytic activity towards N2O decomposition of six different Ru/Fe/Al2O3 nanoparticle powders synthesized by flame spray pyrolysis (FSP) was investigated. The powders were characterized by X-ray diffraction and N2 adsorption with the BET method. The catalytic tests were conducted with a feed of N2O dissolved in helium in a tubular fixed bed reactor. The prepared powders were found to have a BET specific surface area of approximately 170 g/m2. The prepared powders were catalytically active in the direct decomposition of N2O; 50% conversion of N2O was achieved at approximately 380 °C with the best-performing catalyst. The activity of the catalysts improved as the content of ruthenium increased until 2 wt%, after this point no improvement of the activity with higher Ru content was observed. The addition of iron when Ru was already present did not result in any improvement of the catalyst performance under the studied conditions compared to a Ru-only sample, however, a Fe/Al2O3 powder was found to shift the decomposition of N2O towards lower temperatures compared to the spontaneous thermal decomposition. 1. INTRODUCTION Nitrous oxide (N2O) is very harmful to the environment. It is the third most important greenhouse gas after carbon dioxide and methane: in 2004, nitrous oxide accounted for 7.9% of total greenhouse gas 1 (GHG) emissions in the world on a CO2-equivalent basis .

  • Catalytic Converter Theft Information Bulletin
    CATALYTIC CONVERTER THEFT INFORMATION BULLETIN FRANKLIN-BINGHAM FARMS POLICE DEPARTMENT Crime Prevention Bureau (248) 626-9672 WHAT IS A CATALYTIC CONVERTER? A catalytic converter is an air pollution abatement device that removes pollutants from motor vehicle exhaust, either by oxidizing them into carbon dioxide and water or reducing them into nitrogen and oxygen. The catalytic converter device uses a catalyst to convert three harmful compounds in the car exhaust into harmless compounds. The three compounds are: -Hydrocarbons -Carbon monoxide -Nitrogen oxides In a catalytic converter, the catalyst (in the form of platinum and palladium) is coated onto a ceramic honeycomb or ceramic beads that are housed in a muffler-like package attached to the exhaust pipe. The catalyst helps to convert carbon monoxide into carbon dioxide. It converts the hydrocarbons into carbon dioxide and water. It also converts the nitrogen oxides back into nitrogen and oxygen. PHOTO FROM “HOW IT WORKS.COM” WHY ARE CATALYTIC CONVERTERS POPULAR WITH THIEVES? Converters use the metals Platinum and Palladium as the catalyst. Both of these metals are extremely expensive and provide for high reward versus the risk in committing the theft. Per CNNMONEY.COM, on 03/04/10: Gold sold for $1,133.10 per troy ounce while Platinum sold for $1,582.40 per troy ounce. 2 WHAT DO CATALYTIC CONVERTERS LOOK LIKE?

  • Diesel Catalytic Converters As Emission Control Devices
    DIESEL CATALYTIC CONVERTERS AS EMISSION CONTROL DEVICES Sanaa el Banna and Osama Nour el Deen *EGPC ** Ministry of Petroleum 1. INTRODUCTION; Internal combustion engines are devices that generate work from combustion reactions. Combustion products under high pressure produce work by expansion through a turbine or piston. The combustion reactions inside these engines are not necessarily neutralizing or complete and air pollutants are produced. There are three major types of internal combustion engine"' in use today: !) the spark ignition engine, which is used primarily in automobiles; 2) the diesel engine, which is used in large vehicles and industrial systems where cycle efficiency offers advantages over the more compact and lighter-weight spark ignition engine and; 3) the gas turbine, which is used in aircraft due to its high power/weight ratio and is also used for stationary power generation. Each of these types of engine is an important source of atmospheric pollutants. Automobiles are the one of the major source of carbon monoxide, unbumed hydrocarbons, and nitrogen oxides. Probably more than any other combustion system, the design of automobile engines is now being guided by requirements to reduce emissions of these pollutants. While substantial progress has been made in emission reduction, automobiles remain important sources of air pollutants. TESCE, Vol. 30, No.2 <&> December 2004 In order to reduce emissions, modem cars have been designed to carefully control the amount of fuel they bum. The goal is to keep the air-to-fuel ratio very close to the "stoichiometric" point, which is the calculated ideal ratio of air to fuel. Theoretically, at this ratio, all of the fuel will be burned using all of the oxygen in the air.
