Diagnosing EGR And Secondary Air Systems

The perfect internal combustion vehicle would be able to put the exact amount of fuel and air into the combustion chamber. If the perfect combustion event happened, you would get nothing more than water and carbon dioxide. We are not there yet. In the mean time, we have exhaust gas recirculation systems (EGR), secondary air injection and catalytic converters.

Platinum prices, catalytic converter thefts on the rise?

Platinum miners in South Africa went on strike toward the end of January. This situation half a world away could have real impact on the price, sales and safety of catalytic converters. Also, read how some resourceful shops are marketing services to guard against the rise in catalytic converter thefts.

How Does The EGR And Secondary Air Injection Work With The Catalytic Converter?

The perfect internal combustion vehicle would be able to put the exact amount of fuel and air into the combustion chamber. If the perfect combustion event happened, you would get nothing more than water and carbon dioxide. There would not be any unburned fuel or oxygen. What would be needed to make this happen? Direct injection into the combustion chamber is a good start. You would also need the perfect combustion chamber free from hot spots – areas of unwanted turbulence or carbon build up. In the mean time, we have exhaust gas recirculation systems (EGR), secondary air injection and catalytic converters to reduce emissions

Diesel Particulate Filters: Regeneration

The increased use of EGR valves has led to a bigger problem with soot. So, in order to trap the soot, the government has mandated that all trucks built after Jan. 1, 2007, have a diesel particulate filter (DPF) and a catalytic converter. In simple terms, the DPF is a huge screen that traps the soot coming from the engine. This filter looks like a rocket shell underneath newer trucks. The DPF has temperature sensors and pressure tubes used by the PCM to help in determining when the DPF screen is full. When the DPF needs cleaning it undergoes what is called “regeneration.”

Tech Tip: Clogged Oil Line Leads To Chrysler/Dodge Turbocharger Failure

Extreme temperatures cause the oil circulating through the turbocharger oil feed line to burn. The coked oil buildup restricts oil flow, which leads to turbocharger failure. The oil line may appear fine externally.

Catalytic Converters: New Diagnostic Strategies

Catalytic converter failures on today’s vehicles are rarely caused by defects in catalytic converters. Most catalytic converter failures can be traced back to problems caused by what happens in the combustion chamber. Almost every part on the engine determines how long it will last. It could be a faulty line of computer code that pulses an injector too long, or it could be a stuck piston ring that allows oil to be sucked into the combustion chamber. These little details can limit the life of a catalytic converter.
