Detroit Diesel Series 60 Fuel Pump: An Overview

The Detroit Diesel Series 60 fuel pump is a critical component responsible for delivering fuel to the engine’s injectors at the precise pressure and timing required for efficient combustion. This mechanical pump plays a vital role in the overall performance and fuel economy of the engine. Variations in design and functionality occur across different Series 60 engine models and years.

The fuel pump is designed to draw fuel from the fuel tank, pressurize it, and then send it to the injectors. Precise fuel delivery ensures optimal engine operation, emission control, and power output.

Fuel Pump Functionality

The primary function of the Detroit Diesel Series 60 fuel pump is to supply the injectors with a consistent and properly pressurized stream of fuel. The pump achieves this by drawing fuel from the fuel tank, passing it through a series of internal components that increase the pressure. This pressurized fuel is then delivered to the fuel injectors, which atomize the fuel and inject it into the cylinders for combustion. The timing and quantity of fuel delivered are crucial for maximizing engine efficiency and minimizing emissions.

Types of Series 60 Fuel Pumps

While the fundamental principle remains the same, there can be variations in the design and specifications of fuel pumps used in different Series 60 engines. These differences are usually dictated by engine horsepower, application, and emission standards. Some variations include:

• Mechanical Fuel Pumps: The original and most common type, driven directly by the engine.
• Electronically Controlled Unit Injector (EUI) Systems: In some later models, the fuel injection system uses electronically controlled unit injectors. While these systems still have a pump to supply fuel to the injectors, the injection timing and quantity are controlled electronically.

Maintenance and Troubleshooting

Regular maintenance is vital to ensure the longevity and proper function of the Series 60 fuel pump. This includes regular fuel filter changes to prevent contaminants from entering the pump, and periodic inspections for leaks or other signs of wear. Common problems include fuel leaks, low fuel pressure, and pump failure. Symptoms of a failing fuel pump can include hard starting, reduced engine power, poor fuel economy, and rough idling.
