So, only use your exhaust brake in a state of emergency. Wherever possible, you should use the regular disc brakes first. Exhaust brakes significantly slow down your diesel vehicle quickly. This means, you will need to use up more diesel fuel to re-accelerate and gain speed again.
These three types of braking can be confused with one another but they work quite differently! I will cover each of them a bit more after. Exhaust brakes are used mainly by diesel engines, they compress the exhaust gasses into the manifold where they flow back and stop the movement of pistons. Exhaust brakes are usually used for big trucks where the brake discs alone are not powerful enough.
Engine Brakes on the other hand are the simplest solution for a gasoline engine. It works by removing your feet from the throttle while in gear. This closes the throttle body — preventing any more air to enter and thus slowing down the pistons. Jake brakes — like exhaust brakes — work by operating with the exhaust valves. During a Jake brake, exhaust valves are opened prematurely to let pressure out of the cylinder. This means instead of letting the pressure push the pistons down, the pressure escapes into the exhaust system — removing the power source to move pistons and thus slowing down your vehicle.
Exhaust brakes as we described, work simply by closing the exhaust valves in the manifolds with mechanical valves. Instead of having the exhaust gases flow out into the exhaust system, they buildup and flow back into the cylinders — causing significant pressure that goes against the moving pistons and slowing it down. They are very effective and simple to use in case of emergencies or when you need strong braking power.
Unlike Jake brakes, exhaust brakes do not produce unpleasant sounds when applied — because of this they are fully legal in many countries.
During engine braking, you let go of your foot from the gas paddle. This closes the throttle body and prevents any more air from entering.
This actually creates significant pressure — which stops the pistons from pulling itself. Imagine taking an empty syringe. Cover the syringe with your finger tip and try pulling the syringe. Did you manage to pull it down? When the exhaust brake is applied and the inline butterfly valve is partially closed, significant additional force is required to push the spent exhaust from the engine.
As the engine slows, the vehicle decelerates. In some exhaust brake systems, the vehicle computer controls their operation. In others, the driver can manually actuate the exhaust brake. With either system, the mechanism which closes the butterfly valve may be powered by hydraulic pressure, air pressure or rely on an electronically operated servo motor. Many diesel powered vehicles have supplemental braking systems, such as exhaust brakes.
As a diesel technician , familiarity with their use and operation are important skills to have for your career. The braking systems require occasional maintenance and some users report decreased effectiveness over time.
Properly inspecting, diagnosing, repairing and maintaining exhaust brake systems are important skills to have and can take you far in this industry. One of these programs is the agricultural equipment technician training program , which was created with Fendt, part of the AGCO Corporation. In this week program, students who qualify learn the ins and outs of working on agricultural equipment.
They also earn valuable agricultural technician qualifications that can give them a competitive edge as they start their careers. To learn more, request information today. While times might seem uncertain, the demand for diesel techs remains. He works as a Caterpillar field service tech by day. And he's an entrepreneur by night. This rate excludes graduates not available for employment because of continuing education, military service, health, incarceration, death or international student status.
The rate includes graduates who completed manufacturer-specific advanced training programs and those employed in positions that were obtained before or during their UTI education, where the primary job duties after graduation align with the educational and training objectives of the program. UTI is an educational institution and cannot guarantee employment or salary. Individual circumstances and wages depend on personal credentials and economic factors.
Work experience, industry certifications, the location of the employer and their compensation programs affect wages. Awards vary due to specific conditions, criteria and state. Bureau of Labor Statistics, Employment Projections , www.

Entry-level salaries may be lower. UTI programs prepare graduates for careers in industries using the provided training, primarily as automotive technicians. Some UTI graduates get jobs within their field of study in positions other than as a technician, such as service writer, smog inspector and parts manager. Once the exhaust brakes are installed, they can make a vehicle safer and more secure on the road and they minimize the likelihood of putting the car in a ditch or in a tree when driving on countryside.

When used as recommended, they save money by reducing brake service costs and offer added security if you are traveling or pulling a rig in hill country.
Not all diesel engines can be fitted with an exhaust brake. The engine must be large enough to room proper mounting and have stronger components installed.
