What is an exhaust brake indicator light?

The picture is meant to be a throttle plate in the closed position (the horizontal line with the dot in the middle) and air being stopped by the plate (the vertical lines).
What is exhaust brake on Isuzu?
An exhaust brake is a means of slowing a diesel engine by closing off the exhaust path from the engine, causing the exhaust gases to be compressed in the exhaust manifold, and in the cylinder. Since the exhaust is being compressed, and there is no fuel being applied, the engine slows down the vehicle.
What is the exhaust brake button for?
Essentially, it works by trapping engine pressure in the exhaust system, which in turn forces the engine to rotate slower (backpressure). This additional force slows the engine’s rotational speed. As the engine slows, the vehicle decelerates. In some exhaust brake systems, the vehicle computer controls their operation.
Should I drive with my exhaust brake on?
It is recommended to leave it on as much as possible. It helps keep the turbo vanes free of soot, and saves wear and tear on the brakes.
Do exhaust brakes hurt the engine?
The exhaust brake can cause unintended changes of direction on a slippery road… It will never hurt the engine for it to be on though.
When should I use the exhaust brake?
Exhaust brakes can prevent a vehicle from going downhill too fast. In a similar fashion, if a driver transports a fifth wheeler, a caravan or a loaded trailer and he needs to go downhill, the exhaust brake can prevent the vehicle from going too fast and it reduces the likelihood of an accident.
Does exhaust brake use more fuel?
Using the exhaust brake with engine braking shortens the braking distance, but increases fuel consumption.
Why is my exhaust brake not working?
Either the electronic boost sensor has failed or the vanes inside the turbo are sticking in the wrong position. The most likely cause of both the exhaust brake not working and lack of boost on the low-end stem from the variable-vane actuators inside the turbo being clogged with carbon deposits (soot).
Are exhaust brakes bad?
Exhaust brake is typically a butterfly valve in the exhaust that closes and creates back pressure that makes for braking action. This can cause engine damage if not adjusted properly.
Are exhaust brakes hard on transmission?
No — to answer your question. This is what it’s built to do. The transmission locks up in the gears, the vanes close in the vgturbo and then you get braking. If it gives you joy (not mocking you), do it.
Does exhaust brake help warm up?
“Operating the exhaust brake at idle will greatly improve warm up rate and will help keep the engine close to operating temperature during extended idle.” “The exhaust brake feature can also be used to reduce the engine warm up time.
When should you not use Jake brake?
Do not use the Jake in icy or slippery road conditions! Avoid using it when the truck is not going at a controlled speed, also. 2. If you must use it, make sure your trailer is straight and lined up behind the cab to prevent jackknifing.
