SGV Exhaust brakes Australia

Effect on engine and transmission

 

Very detailed experiments has been carried out all over the world and resulant findings are comparable. Without going into too much detail of stresses and strains, the findings are as follows:

When an exhaust brake is fully applied ,the pressure build - up is generally 40/50 lbs. per sq. inch and does not exceed 70 lbs. per sq. inch even with a petrol engine. This is considerably less than the pressure reached in normal firing sequence. The effect of this pressure is felt as a "cushion" on the pistons, connecting rod, crank shaft and bearings, which normally undergo severe stresses.

The exhaust brake controls the revolutions, keeps the engine at operating temperatures, and prevents any possibility of oil dumping because of the pressure maintained on the piston.

Engine valves and valve springs are uneffected. The normal sequence of operation occurs and the brake neither benefits nor harm the valves. Normal engine temperatures are maintained whilst the brake is in operation.
