The compression release engine brake works in concert with the engine's positive power valvetrain to effectively convert a diesel engine from a power producing machine into a power consuming air compressor through selective control of various engine valves.
Compression release engine brake or JakeBrake[R] is a device commonly found in vehicles operating over 30 tons.
While driveline retarders provide increased retarding performance over standard compression release brakes, they are an expensive option which add considerable mass to the vehicle and can exceed the thermal capacity of the radiator during prolonged retarding .

Since this was John Deere's first diesel, a compression release
had not been built in and the injection rack stuck open.
Other standard features include mechanical governors; recoil starters with automatic compression release
(a 12 V electric starter is available as an option); integral fuel tanks; external fuel filters; full flow oil filters; dry type air cleaners; and shielded mufflers.

The finishing touch is a flush-mounted compression release
, located near the starter-rope handle.
The new 15LD225 is mechanically governed, has recoil starting and automatic compression release
as standard, with an electric start option.
The compression release system has also been fine-tuned to work in concert with Robin's HotSpark electronic ignition system, Murphy said.
It allows us to adjust the timing to coincide with the compression release," said Murphy.
