Universal joints that stay put Every time you add a universal joint to an extension, you know the socket is going to weigh it down, making it hard to fit onto the fastener. I saw this Titan Tools 3 Pc. Auto Flex Universal Joint at SEEMA Show 2022 and had a chance to try it.

Wrench organizer trays that really hold Wrench organizer trays from Ernst Manufacturing I found this neat Ernst Manufacturing wrench storage system at SEEMA 2022. Most wrench trays are designed for a particular wrench brand. But these wrench storage trays accept all brands. Just snap the wrench into place and it stays even if you carry the tray to your work site. Full assortment of wrench organizer tray sizes Ernst makes just about any size organizer to fit your wrench set and toolbox. Choose from trays that hold 4, 5, 6, … Read More

Socket organizer system from Ernst Manufacturing I found this neat system at SEEMA 2022. Most socket rails are either spring clips or magnets. But the SocketBoss is different. Just twist the socket to lock it to the rail and untwist to remove the socket. They mount drive-end down. Buy the socket rails individually or in a set with a tray. To remove a rail from a tray, just push a button and it unlocks. Choose from Blue, Red or Yellow • 15 locking clips per rail • Move the clips … Read More

Particulate Matter  Filter Monitor — PM Monitor Used only on diesel engine the particulate matter (PM) filter removes particulate matter from the exhaust stream by filtration. The filter has a honeycomb structure similar to a catalyst substrate, but with the channels blocked at alternate ends. This forces the exhaust gas to flow through the walls between the channels, filtering the particulate matter out. The filters are self-cleaning by periodic modification of the exhaust gas concentration in order to burn off the trapped particles (oxidizing the particles to form CO2 and … Read More

Exhaust Gas Sensor Monitor Used only on diesel engines, the exhaust gas sensor is used to determine the content of the exhaust stream. The computer checks for component integrity, system operation, and tests for faults in the system, as well as feedback faults that may affect other emission control systems. The Exhaust Gas Sensor Monitor is a “Two-Trip” Monitor. If a fault is found on the first trip, the computer temporarily saves the fault in its memory as a Pending Code. The computer does not command the MIL on at … Read More

Boost Pressure System Monitor The boost pressure system is used on diesel engines to increase the pressure produced inside the intake manifold to a level greater than atmospheric pressure. The pressure increase helps to ensure compete combustion of the air-fuel mixture. The Boost Pressure System Monitor checks for component integrity and system operation, and tests for faults in the system. The computer runs this Monitor once per trip. The Boost Pressure System Monitor is a “Two-Trip” Monitor. If a fault is found on the first trip, the computer temporarily saves … Read More

NOx Aftertreatment Monitor Diesel vehicles are now required to reduce NOx even further. A special catalytic converter is used to accomplish the NOx reductions. The catalytic converter is treated with a special washcoat containing zeolites. The zeolite acts as a molecular “sponge” to trap the NO and NO2 molecules in the exhaust stream. In some implementations, injection of a reactant before the aftertreatment purges it. NO2 in particular is unstable, and will join with hydrocarbons to produce H2O and N2. The NOx Aftertreatment Monitor monitors the function of the NOx … Read More

Non-Methane Hydrocarbon Catalyst (NMHC) Monitor Some diesel vehicles include an extra catalyst called a Non-methane Hydrocarbon Catalyst. It’s designed to remove non-methane hydrocarbons (NMH) left over from the combustion process from the exhaust stream. The NMH catalyst materials react with the exhaust gases to convert CO, HC, Particulate Matter and Soluble Organic Fraction into CO2 and H2O. The computer checks the efficiency of the catalyst by monitoring the quantity of NMH in the exhaust stream. The monitor also verifies that sufficient temperature is present to aid in particulate matter (PM) … Read More

Secondary Air System Monitor Secondary air systems are used to jump start a cold catalytic converter and to cut down on cold start emissions. A catalytic converter must reach approximately 400° to 600°F in order to properly reduce emissions. When a cold engine is started, a large amount of fuel is unburned due to the “quench” effect of the cold combustion chamber and cylinder head. That unburned fuel then enters the cold catalytic converter where there’s not enough oxygen to burn it off. Lacking extra oxygen and heat, that raw … Read More
