Cummins Parts

Cummins specializes in the design, engineering, and manufacture of engines and related technologies, including fuel systems, controls, air handling, filtration, emissions, and electrical power generation. For the motor vehicle sector, Cummins parts and complete engine systems are available for heavy duty commercial vehicles, buses, mining, construction, and forestry vehicles.

Cummins Engines for Trucking

From delivery trucks to full-sized tractor-trailers, Cummins offers a comprehensive range of engine systems to help owners and operators get the most value out of their trucks.

Medium duty. Cummins takes pride in its vast range of engine solutions for medium duty trucks, ranging from conventional diesel engines to its Cummins Westport natural gas and near-zero emission engines. These engines are designed to maximize uptime and minimize fuel consumption. Fuel savings are a crucial focus for Cummins, with engines tuned to specific combustion ratios and enhanced turbo efficiency to deliver high torque within the critical RPM range. These result in an average fuel economy improvement of 8.5% for efficiency series engines than previous models. Some applications, such as pickup and delivery, can reach as high as a 13% improvement. Performance series engines also experience an average fuel economy increase of 5% and gains of up to 11% in specific duty cycles and applications. Backed by R&D, manufacturing, and testing processes developed over the course of more than 30 years, Cummins medium-duty engines have set the bar in the industry with a proven track record in the midrange lineup. So it’s no surprise that Cummins engines power more medium-duty trucks across North America than any other engine.

Heavy duty. Cummins’ heavy duty 15-liter and 12-liter engines are built for improved uptime, ease of operations, and a better return to the total cost of ownership. These engines are available in configurations that cater to the customer’s specific needs, whether it’s enhanced driver performance, power output, or less downtime at the shop. Cummins’ 12-liter engine offers efficiency and productivity for medium-bore engine applications that surpass that of 11- to 13-liter powertrains. In addition, these engines are designed with Cummins transmissions system in mind, resulting in the market’s lightest integrated powertrain option with maintenance intervals unsurpassed by the competition. For linehaul and regional haul applications, Cummins 15-liter engines deliver consistent performance for demanding applications. Customers can choose from models tuned for efficiency, productivity, and sheer power to meet various vocational and heavy haul applications. When it comes to heavy duty over-the-road powertrain solutions, Cummins sets the standard in the market.

Light commercial. Cummins’s light commercial vehicle (LCV) engine range is engineered to deliver exceptional, low-cost performance for light duty trucks, vans, pickups, and utility vehicles. These engines are optimized for fuel efficiency, low cost, and low emissions, which are in line with Cummins’ commitment to producing the cleanest diesel engines in the world.

Vocational. Whether it’s a refuse truck, concrete mixer, or dump truck, vocational vehicles don’t have an easy life. This is why Cummins vocational engines are built to meet the horsepower and torque needs of these hardworking vehicles and equipment. These engines are available in both diesel and natural gas options, giving customers flexibility in choosing the fuel that makes the most sense for their operations. Cummins engines also offer competitive maintenance intervals and decades of reliable performance for maximum value.

Cummins Engines for Bus

Whether it’s transporting kids to school or commuters to their workplace, Cummins bus engines are sturdy, reliable, and deliver consistent uptime to ensure safe and efficient transport.

Transit. Manufactured at its Rocky Mount facility in North Carolina, Cummins offers a range of 200-380hp engines for transit buses and similar vehicles. For local shuttle bus operations, Cummins’ hybrid models are a great fit. Authorities looking for alternative energy options can also choose from engines that run on compressed natural gas (CNG), liquid natural gas (LNG), and renewable natural gas (RNG). Cummins transit engines also have unique features, including an advanced Single Module Aftertreatment System that provides better thermal management, easier maintenance, and a small profile for improved shuttle bus performance and fuel economy. Cummins natural gas engines also feature a maintenance-free three-way catalyst that uses an optimized natural gas and oxygen combustion ratio for an oxygen-free exhaust flow.

School bus. When it comes to a clean-running and reliable power source for your school bus fleet, you can never go wrong with Cummins. Produced entirely in its Columbus, IN and Rocky Mount, NC facilities, Cummins school bus engines meet or exceed 2017 U.S. Environmental Protection Agency (EPA) regulations and greenhouse gas (GHG) emissions standards. In addition to cleaner engines, Cummins also offers its Connected Diagnostics system that delivers real-time engine fault code analysis, a probable diagnosis, and recommended action for school buses fitted with telematics. School bus drivers already have more than enough on their plate to worry about engine fault codes, so in the event that one is triggered while driving, it can be diagnosed almost instantly over the air.

Electric buses. With more than 100 school districts switching to all-electric school buses, Cummins’ fleet of electric buses offers zero emissions and lower fuel costs. There are also fewer moving parts to deal with, no air and oil filter changes to remember, and smog checks to think about, drastically cutting down on service and maintenance. And with improved air quality and less noise in the neighborhood, these low-emission electric buses help the community breathe and live better.
