Inter Diesel Engines, also known as International Diesel Engines, are produced by International Harvester, a company with a rich history in the manufacturing of agricultural machinery, vehicles, and engines. International Harvester was founded in 1902 in the United States and became a significant player in the development of diesel engines over the 20th century.
The company's venture into diesel engine production began in the 1930s when diesel technology was becoming more viable for industrial, agricultural, and commercial use. International Harvester designed and manufactured diesel engines for a variety of purposes, including trucks, tractors, and power generation, other heavy machinery. Their engines were known for their durability and reliability in tough working conditions, which made them a popular choice in industries that required robust power sources.
International Harvester engines were widely used in trucks under the "Navistar" brand after the company's restructuring in the 1980s. Navistar continued the legacy of International Harvester's diesel engines by producing high-performance diesel engines for commercial vehicles, buses, power generation and industrial applications.
The legacy of Inter Diesel Engines, through International Harvester and Navistar, played a key role in shaping the diesel engine industry, particularly in North America, where their engines were commonly found in various transportation and industrial sectors.
