Turbocharging technology works by forcing fresh air into the engine. Energy from the diesel engine exhaust that would otherwise be wasted rotates a turbine. The turbine is coupled to a compressor that pressurizes incoming air into the combustion chambers, generating a virtually instantaneous surge of on-demand power, significantly increasing output per liter.
As the name suggests, an exhaust brake uses the exhaust system to slow your vehicle down. It offers several benefits: it can reduce wear and tear on the regular brakes, help regulate speed (and prevent brakes from overheating) when driving downhill.
