Fuel systems are essential components that ensure the proper delivery of diesel fuel to the engine for combustion. These systems are designed to supply the engine with the right amount of fuel at the right pressure and timing. 

Cummins leverages over 80 years of fuel systems experience in its current operations. Cummins fuel systems enable engines to meet increasing emissions requirements while maximizing fuel economy and performance. Our advanced, world-class technologies help you get the most out of your fuel system while we continue creating innovative products to meet your future needs.

Here are the key components and aspects of our fuel systems:

•    Fuel tank
•    Fuel lines
•    Fuel filter
•    Fuel pump
•    Fuel injectors
•    Injection pump
•    Governor
•    Injector nozzles
•    Fuel pressure regulator
•    Fuel heater (optional)
•    Fuel return system
 

Turbocharger technologies are designed to enhance the performance and efficiency of internal combustion engines, particularly in terms of power output and fuel efficiency. A turbocharger consists of a pair of fans, a turbine, and a compressor, all housed in a single unit. The primary purpose of a turbocharger is to increase the volume of air that can be delivered to the engine's combustion chambers.

For more than 60 years, we have delivered innovative and reliable turbocharger solutions for our customers. Today, Cummins Turbo Technologies engineers are actively developing state-of-the-art solutions for the next generation, including assisted turbocharging, new bearing systems, and enhanced compressor stage performance.

Our turbocharger technologies capabilities include:

•    Fixed Geometry Turbochargers
•    Wastegate
•    Variable geometry turbochargers (VGT)

Valvetrain technologies refer to the components and mechanisms responsible for controlling the opening and closing of the engine's intake and exhaust valves. The valvetrain plays a critical role in regulating the flow of air and exhaust gases into and out of the combustion chambers, influencing engine performance, efficiency, and emissions. 

By pioneering compression release technology, advancing next-generation valvetrains, and introducing cutting-edge engine braking systems, Cummins consistently elevate the benchmarks of performance. Our relentless commitment focuses on enhancing power, optimizing fuel efficiency, and minimizing emissions, thus redefining the potential achievable by commercial vehicles.

Here are some valvetrain technologies where we focus our efforts:

•    High Power Density Engine Brake 
•    Compression Release Engine Brake 
•    Lashless Valvetrain with Engine Braking
•    Bleeder Brake 
•    Exhaust Brake
