A diesel engine exhaust brake can help you avoid the feeling of panic in hard or prolonged braking situations with diesels engine vehicles. Gasoline engines are designed with a throttle or butterfly valve that closes the air intake of the engine forming a vacuum effect that assists the vehicle in braking. Diesel powered engines have no such butterfly valve and thus no compression is developed when the throttle is released during braking. This means the brakes are given the entire task of getting the vehicle stopped.
Additional information can be found at the manufacturer's Diesel Engine Exhaust Brakeweb pages. We are an authorized dealer and can supply most any of the US Gear D-Celerator products.
Top: Valve Open Bottom: Valve Closed
The D-Celerator uses back pressure to provide supplemental braking. An oversize nodular iron housing consisting of two stainless steel butterflies (one large, one small) is added to the exhaust system in front of the muffler. The large version is in the main passage, while the small butterfly operates in a separate waste gate by-pass port. Available from 2-1/2" up to 4" . When signaled, the large butterfly closes , creating immediate exhaust pressure for assisting the vehicle's regular brakes. Gas flow is now directed through the small by-pass port and released by the small butterfly at at pre-determined pressure. This maintains the back pressure longer, providing precision braking whenever you need it. This system does not require valve spring changes or engine modifications.
The key elements to determining which model is applicable is the diameter, lbs of spring pressure and whether it is electronic.
