In the diesel world, "blow-by" is a term you're bound to run across at some point if your line of work involves diesel-powered vehicles of any kind. What is blow-by, what causes it, and how concerned should you be? At Wensel Service Centers in Spring City, Allentown, & Reading, PA, our fleet maintenance and diesel technicians see it on a regular basis. Here we'll take a quick look at blow-by, correcting it, and preventing it.

What is Blow-By? - Diesel blow-by is a term that describes an event of lost compression into the crankcase. Blow-by occurs whenever a burnt or unburnt fuel and air mixture escape from the cylinder and past the piston rings and into the crankcase. In a perfect world, the piston would be sealed tightly in the cylinder, able to move up and down but keeping all the air and fuel and exhaust that enters or exits the cylinder during the combustion process out of the crankcase. As you'll see, this perfect world doesn't exist, but it is important to minimize the amount of blow-by in a diesel engine.

No matter what type of fleet vehicles or commercial trucks you maintain, the fuel system on your diesel is an integral part of keeping you on the road. Gas systems are pretty simple - there’s basically just a pump that pushes gasoline to the injectors. Diesels are a bit more complicated.

If there’s an issue with your diesel fuel system, the most important thing to remember is to fix it sooner rather than later. With gas engines, you can often power through a fuel issue for quite some time - they’re irritating, but not often permanently damaging. Diesel systems are a little more important, and parts rely heavily on one another to avoid damage and keep working properly, as well as maintenance and repair from professional technicians.

Keeping your fuel system maintained will prevent premature parts failure and poor running conditions. Here are some important aspects of diesel fuel system maintenance, to keep your fleet running smoothly. While your system and components should typically be serviced by a professional technician, there are some things you can be conscious of that will go a long way toward keeping your engine in good shape.

Obviously, your brakes are pretty important. Your brake system is made of many components that all have to work correctly for your brakes to operate seamlessly. If one thing needs to be repaired, the whole system is compromised. Brake pads, rotors, hoses, calipers, and metal lines all play a part in stopping your car. At Wensel Service Centers in Spring City, Allentown, & Reading, PA, we’re here to make sure your car, truck, or SUV stops as it should.

Obviously, the dirtier your fuel system is, the bigger the improvement you will see in performance and fuel economy after a fuel system cleaning. But it is important not to wait until your system is running poorly. If you do, by the time you get a cleaning, you’ve wasted hundreds of dollars in gas or even possibly damaged your fuel injectors and catalytic converter.
