engine maintenance

Diesel trucks are known for their incredibly reliable engines. At National Brake & Muffler in Griffin, we know that the key to a reliable engine is good maintenance. In fleet trucks, the difference between a truck that lasts a million miles and a truck that needs new engine hinges on how well it has been maintained.

When you think about diesel engines, you probably think about large trucks and machinery, and maybe a few oddball cars over the years. So how long has diesel really been around, and why is it used the way it is today? At National Brake & Muffler in Griffin, GA, we have the answers.

At National Brake & Muffler in Griffin, GA, we understand the importance of doing things right. That’s why we are in the business of hiring ASE certified technicians. After all, your car, truck or SUV is only as good as the quality of service it receives.

fuel being put into vehicle

Your car’s fuel system works with the rest of the engine control system to deliver the best performance with the lowest emissions. Check your car’s fuel system regularly or immediately if you smell gas or suspect a problem.

What does it do? - The fuel system transfers fuel from the fuel tank and passes it through a fuel filter for straining before it arrives at the injectors. A pressure regulator controls fuel pressure to ensure good engine performance under a variety of speed and load conditions. Fuel injectors, when activated, spray a metered amount of fuel into the engine. Some vehicles use a return line system to return unused fuel back to the tank.

At National Brake & Muffler in Griffin, our expert mechanics understand the importance of good quality oil, changed at correct intervals, in allowing you to get the most out of your Cummins, Powerstroke, or Duramax diesel.

Now that you’ve got an idea of the components that make up a diesel system, and what they do, understanding how the system works in a more cohesive way isn’t difficult. At National Brake & Muffler in Griffin we understand what’s going on in your fuel system while your diesel engine is running.
