BLOOMFIELD, Conn. — Jacobs Vehicle Systems has announced that it is marking the sale of its four millionth Jacobs Engine Brake this month.

Since the Connecticut-based manufacturer pioneered engine retarding technology in 1961, the Jacobs Engine Brake has become an integral part of truck engines worldwide, states the company.

What began as an idea of inventor Clessie Cummins has evolved from an aftermarket option into an essential technology for diesel engines, according to Jacobs. Getting involved early in the engine design cycle has allowed Jacobs to make continuous improvements in retarding performance and engine interface reliability, the company adds. 

“Engine braking technology has evolved over the last 48 years from an add-on for large diesel truck engines, to a device now fitted to all sizes of commercial vehicle diesels, bringing more control and financial benefits to truck owners around the globe,” said Bob Perkins, vice-president of marketing at Jacobs Vehicle Systems.
