Fuel Injector
Mack

Fuel injectors deliver precise quantities of fuel into each cylinder, controlled by the engine’s fuel pump and electronic control system. In modern heavy-duty engines, injectors atomize fuel into a fine spray, promoting efficient combustion, reduced emissions, and steady power delivery under varying loads. A worn or clogged injector can cause rough idling, misfires, increased fuel consumption, and elevated exhaust temperatures, making clean, dependable spray essential. This injector features tight tolerances, corrosion-resistant materials, and seals designed to handle diesel fuel and high-heat cycles. Proper testing involves spray pattern analysis, flow testing, and leak checks at operating pressure. Replacement should consider the engine type, injector calibration, and compatibility with the fuel system’s rails and connectors. When selecting, match the part to the original design to preserve timing, atomization quality, and injector response.
