Engine brakes
#6

Jacobs type brakes open the exhaust valve on compression stroke, hence the name 'exhaust' brake. PacBrake and others close off the exhaust gas flow after the turbo. In most cases the PacBrake types are sort of useless. Volvo makes their own type of engine brake as well. The older Cats (1693 and 3400 series) used a retarder using engine oil as part of the bell housing. I have one if these in a 1973 Pete with the 1693. Engine oil heats up quickly in mountainous terrain. These are quiet but not as useful as the "Jacobs" style. Newer Cats use the 'Jacobs' type.
