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.
Honda Accord owners may report a thump as the ignition switch is released from the start position or as the engine starts. This noise sounds similar to a rubber mallet striking the frame and occurs only on a cold start (the vehicle has been sitting for some time, usually overnight).
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
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.”
Are you one of the 7,570 technicians who are ASE-Certified Undercar Specialists? If not, you should be. I recently took the X1 Exhaust Test to qualify as an Undercar Specialist.

A useful diagnostic tool is to determine if the fuel trim problem exists in more than one engine operating range. Fuel trim should be checked at idle, at 1,500 rpm and at 2,500 rpm. In addition to these no-load checks, drive the vehicle at various steady load conditions and watch for fuel trim variation.
