Diesel Engine Manufacturing Powers State Economies, American Jobs

Oct. 8, 2019 – In 2018, more than 1 million heavy-duty diesel engines were manufactured in facilities across the United States – a growth of 13% over the previous year, or nearly 120,000 engines, according to new data from the Diesel Technology Forum.


Thirteen states are home to heavy-duty diesel engine manufacturing, with North Carolina producing more than one-in-three U.S.-made heavy-duty diesel engines. Other key states include Indiana, Ohio, Michigan, and New York.

“American-made heavy-duty diesel engines are the workhorse of the economy, fueling half the key U.S. economic sectors with proven, economical, efficient, and now near-zero emissions technology,” said Allen Schaeffer, executive director of the Diesel Technology Forum. “From agricultural, mining, and construction equipment, to commercial vehicles, trucks, buses, locomotives, tugboats, and other goods-movement equipment, diesel remains the powertrain of choice.”

Schaeffer continued, “The growth in diesel engine manufacturing is a clear indicator of the importance and future of this technology. U.S.-based heavy-duty diesel engine manufacturing facilities are producing the latest new-generation diesel technologies, which not only are near-zero emissions, but also lower in greenhouse gas emissions and consume less fuel.”

In just the first quarter of 2019, heavy-duty clean diesel engines directly supported more than $4 trillion in U.S. economic activity. Diesel-related jobs totaled almost 265,000, with wages and salaries above the national average and a job-growth outlook of 5% each year, according to the 
U.S. Bureau of Labor Statistics.

The agricultural, mining, construction, transportation, and logistics industries are directly dependent on heavy-duty diesel engines. 
According to the U.S. Bureau of Economic Analysis, these diesel-dependent industrial sectors have grown by 6% over last year. These sectors represent more than 12% of all private-sector industrial activity.

New analysis from the Diesel Technology Forum provides insights into the broad impact of diesel engine manufacturing on state economies. A look through the Forum’s 
searchable, state-by-state database further shows how diesel is the workhorse of each state’s economy and transportation systems. This resource identifies each state’s diesel-related manufacturing and jobs; number of renewable fuel producers and stations; diesel fuel consumption; and population of diesel-powered commercial trucks, marine vessels, transit and school buses, and passenger vehicles.

Beyond manufacturing, each state’s economy benefits from large workforce and training sectors dedicated to servicing and maintaining diesel engines, vehicles, equipment, and fueling operations, along with the public and private services they provide that can be found in every community.
