Preventive Maintenance Inspection (PMI) is a popular practice widely used companies all over the world. It’s an inspection schedule that checks key areas of a vehicle. It’s performed at certain intervals during the year to make sure truck fleets, and construction equipment issues are identified and solved before they become big problems and cost them thousands in repair and downtime.
However, many of these companies run into a problem. They don’t implement these practices or adhere to a schedule. This means their equipment is operating unchecked and the chance of failure is imminent, which means loss of $$$.
As we’ve covered before, carbon and soot is a problem. Its inability to burn complete presents an ever-looming culprit that will eventually rob your bottom line. But if you think it will just affect one injector and make your engine run a little rough think again.
The EGR System


1. As the exhaust exits and enters the EGR valve, the carbon build-up will cause reduced exhaust flow, rough idle and poor acceleration. This means you or your driver will stomp on the gas pedal, wasting more fuel and creating more carbon and soot. $$$
2. The EGR Cooler – The EGR Cooler cools the exhaust from the engine via the EGR valve, using engine coolant and redistributes back to the engine.

This boost helps atomize the fuel mixed with air to create a more efficient combustion. However, carbon and soot will cook on the impeller fans and will not only slow them down causing a rough idle, power loss and poor acceleration but can also cause overheating and cause the impeller shafts to lock up. $$$
Potential Repair Costs
Do the math.
