“Jake brakes” or “Jacob” brakes are colloquial names for a compression release brake. When a diesel engine slows down using its jake brakes, it opens the exhaust valves on top of the compression stroke. This would be similar to taking your foot off the gas so that gravity and other forces can slow your car down.
