[1][2][3] The company made diesels for tugboats, fishboats, coasters, yachts, lightvessels, and other ships.
The company produced engines in a variety of sizes and ratings, from a 2-cylinder model that generated 30 horsepower (22 kW) to an 8-cylinder model that generated 600 horsepower (450 kW).
Known for their reliability and serviceability, Atlas diesels were installed in workboats around the world.
[citation needed] While the Atlas-Imperial factory closed in the 1950s, its engines continued to power vessels well into the era of high-speed, small-cylinder diesel technology.
[citation needed] Today, numerous Atlas Imperial engines remain, with some still in operational condition.
