The Jacobs Engine Brake Application and Performance 660740
The Jacobs engine brake, introduced early in 1961, has enjoyed a success unequaled by any retarding device marketed in this country. Although the engine brake is a new device, it simply harnesses the built-in braking ability which is as old as Dr. Diesel's first engine. The operation, design, and performance of this engine brake are discussed in this paper. As of this writing, approximately 30,000 units are in operation in both on and off-highway applications.
