The company's engines are used in a variety of vessels such as fishing boats and small tugs.
Bergius rented a premises in Finnieston Street, Glasgow, and set about developing his first car which he named the "Kelvin".
Car manufacture was abandoned, and the company began to specialize in marine engines.
The company expanded rapidly with the move to a new factory at Dobbies Loan, Glasgow in 1910.
The model "P" range was introduced in 1956, having been designed by Mr. W. Miller, who joined the company from Petters Limited in 1954.
Bergius-Kelvin was purchased by Ruston & Hornsby in 1966, who in turn were acquired by English Electric.
GEC consolidated all production of Kelvin Engines at Kyle Street in 1983.
