Air Filter Fuel Trim Diagnostics
The modern engine measures two things extremely well, the amount of air going into the combustion chamber with the mass airflow sensor (MAF), and the byproducts that are generated by the combustion event with the oxygen sensor. These measurements allow the engine’s computer to put the right amount of fuel and spark into the cylinder to give the most efficient and cleanest combustion event.
New Innovative Snap-on EVAP Smoke Machine
The new Snap-on EVAP Smoke Machine (EELD100A), featuring the innovative Diagnostic Smoke technology for EVAP testing and all other applications, is unlike anything on the market today, said the company.
Lisle Corp. Offers Mini Zero Degree Ratchet Combo Kit

Pulling Codes: Advanced Misfire and Fuel Trim Analysis, Part 2
Contributing writer Carlton Banks continues with his series on Advanced Misfire and Fuel Trim Analysis, using fuel trims and oxygen sensor behavior to determine if the misfire activity is ignition, engine mechanical or fuel related. This article focuses on fuel-related misfires.

DENSO Develops Highly Standardized Automotive Climate Control Unit
Global automotive supplier DENSO has developed a new automotive climate control unit that can be used for a wide variety of vehicles ranging from compact to luxury cars. Conventional climate control units are often designed and tailored to each vehicle model, but this product has a new structure, which DENSO says enabled the company to standardize components while realizing required performance.

Thumping Noise At Cold Start On Honda Accord
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).
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.”
Why A Clean Fuel Tank Is Important For A Fuel Pump’s Diet
Fuel pump replacement comebacks can be costly and can hurt your reputation. One of the leading causes of failure is the tank. If a vehicle gets 20 miles to the gallon, then more than 5,000 gallons of gas (from many stations) will go through the tank in 100,000 miles. During this time, sediment, rust and debris from the pump can find its way into the tank. Removing all contaminates is critical.
