This is our comprehensive guide to diesel fuel pumps – an essential read for diesel enthusiasts, mechanics, and anyone curious about the inner workings of these critical fuel system components.

As a recap, Exhaust Gas Recirculation Coolers (EGR) cool the exhaust gases, and reduce nitrogen oxide emissions (NOx) for heavy duty internal combustion engines to meet emissions standards set by the US Environmental Protection Agency.

Exhaust Gas Recirculation (EGR) revolutionized diesel engines by enhancing their efficiency and reliability, empowering commercial fleets to mitigate operational costs. But what's the backstory of EGR systems?

Fuel nozzles play a critical role in the efficient functioning of internal combustion engines. However, just like any component in a mechanical system, fuel nozzles are prone to a range of issues which can negatively affect performance, efficiency, and even lead to engine damage if left unaddressed.

Fuel injectors play a crucial role in the modern diesel engine's operation. They finely spray fuel to mix with incoming air before reaching the combustion chamber. When this is working properly, the engine will perform more efficiently, however, if there is a problem with the fuel injector, the performance of the vehicle will suffer.

Diesel engines have enabled humans to build our modern world. In the trucking industry, diesel engines have powered semi-trucks for decades. Over the decades these engines have become more powerful while also becoming increasingly efficient and cleaner. To achieve this the engines have also become more complex.

Fuel injection changed the world of diesel engines making them more efficient and reliable, and enabled commercial fleets to lower their total cost of operation. What is the history of diesel fuel injectors, how do they work, and what do you need to know about them to keep your fleet operating at the lowest cost per mile?

In this article, we will talk about and answer these questions:
