Information:
The compression brake permits the operator to control the speed of the vehicle on grades and on curves. The compression brake also permits the operator to control the speed whenever a speed reduction is necessary, but long applications of the service brakes are not desired. During downhill operation or any slow down condition, the engine crankshaft is turned by the rear wheels through the following components:
Differential
Drive shaft
Transmission
ClutchTo reduce the speed of the vehicle, an application of a braking force can be made to the pistons of the engine. As the engine compression brake is activated, the braking power occurs by opening the exhaust valves near the top of the compression stroke. This releases highly compressed air and energy into the exhaust system. Therefore, no combustion will occur because the engine brake only works under one condition:
The engine is in a "No Fuel" mode. Since the compressed air is released through the exhaust system during the power stroke, a positive power is not generated. The momentum of the vehicle returns the piston to the exhaust stroke. This is a two-step process:
The cylinder vents the compressed air.
The piston relies on the momentum of the vehicle for movement.This two-step process creates the retarding effect for the engine brake. This results in a loss of energy because the work that is done by the compression of the cylinder charge is not returned by the expansion process. This loss of energy comes from the rear wheels which provides the braking action for the vehicle.Components of the Compression Brake

Installed Compression Brake (1) Rear housing. (2) Front housing. (3) Stud. (4) Support bracket. The compression brake consists of two different housings. Both brake housings are installed in the compartment for the valve mechanism above the rocker arms and the rocker arm shaft. Each brake housing is positioned over three cylinders. Each brake housing is mounted on a support bracket (4) at the end of the rocker shaft brackets. Special adjustment screws for the exhaust rocker arm and exhaust valve bridges are necessary. Note: The operation of the compression brakes only uses the exhaust side of the engine valve mechanism.A spacer is used between the cylinder head and the valve cover for the installation of the valve cover. With an installed compression brake, this increase in height is 90 mm (3.5 inch). The front compression brake housing and the rear compression brake housing consist of the following parts:
Three master pistons
Three slave pistons
Three control valves
One solenoid valveEngine Compression Brake's Operation
