Why You Should Keep Your 6.7 Cummins Exhaust Brake Always On

The 6.7 Cummins Exhaust Brake is a feature found in certain Dodge RAM trucks that allows the driver to reduce engine braking when descending long grades. This feature increases safety and improves fuel efficiency by using the exhaust back pressure to slow the engine down instead of using friction brakes. The 6.7 Cummins Exhaust Brake has two settings: “Always On” and “Manual”. When set to “Always On”, the exhaust brake will automatically engage as soon as the vehicle begins a descent, helping to reduce engine speed and wear on the brakes. In “Manual” mode, the driver can activate and deactivate the brake as needed by pushing a button on the dashboard or on the steering wheel. The 6.7 Cummins Exhaust Brake is an important safety feature for drivers who frequently travel in mountainous terrain or who tow heavy loads on long descents, as it can help reduce brake wear and improve fuel efficiency.

Benefits of Exhaust Braking on Diesel Engines

The exhaust brake is a system that works to slow down the vehicle by reducing engine speed. This reduces wear and tear on the brakes and improves fuel economy, as well as providing improved control when descending hills or driving in slippery conditions. Additionally, exhaust brakes can reduce the risk of brake fade due to excessive heat buildup. As such, they are an important feature for those who do a lot of towing or hauling heavy loads.

Disadvantages of Always Having the 6.7 Cummins Exhaust Brake On

While exhaust brakes can be beneficial in some situations, there are potential drawbacks to always having them engaged. The increased noise from the exhaust can be a nuisance for both drivers and nearby residents. Additionally, constant usage may lead to increased maintenance requirements, such as cleaning or replacing components more often than normal. Finally, keeping them engaged may reduce engine performance due to increased backpressure in the cylinders.

How Does an Exhaust Brake Work on a 6.7 Cummins?

Exhaust brakes on 6.7 Cummins engines effectively increase backpressure in the cylinders by preventing oxygen from entering the combustion chamber during compression strokes. To achieve this, valves open up inside the exhaust system and direct exhaust gases through either a turbine or pistons connected directly to the engine’s crankshaft. This creates resistance that slows down the engine’s rotation speed and thereby reduces its speed with greater efficiency than relying solely on conventional brakes alone. The valves close when not in use so that regular operation is unaffected by this additional braking force.

Factors to Consider Before Installing an Exhaust Brake on 6.7 Cummins

Before installing an exhaust brake system on your 6.7 Cummins engine, there are several factors you should consider first in order to determine if it’s right for you and your vehicle’s needs. What type of driving will you be doing? How much weight will you be towing? Do you need high performance? Will it fit your budget? And will it increase your mileage? Answering these questions will help you decide if installing an exhaust brake is right for you and your vehicle’s specific needs and preferences before taking any further steps towards installation.

Introduction

An exhaust brake is a device that helps to reduce vehicle speed without the need for traditional brakes. This is especially beneficial for vehicles such as large trucks, which require more fuel and energy to stop than smaller cars. The 6.7 Cummings engine is one of the most popular engines used in larger trucks and buses, and it comes with an optional exhaust brake system that can be installed. In this article, we will discuss the benefits of installing an exhaust brake system on your 6.7 Cummings engine, common issues with the 6.7 Cummings’ Exhaust Brakes, maintenance tips for keeping it working properly, troubleshooting common issues and cost considerations when purchasing one.

Benefits of Installing an Exhaust Brake System on Your 6.7 Cummings Engine

One of the main benefits of installing an exhaust brake system on your 6.7 Cummings engine is increased safety while driving in hilly or mountainous terrain. The exhaust brake helps to slow your vehicle down as you come down a steep grade or hill, reducing the need to use your regular brakes as much which can cause them to wear out faster over time. An exhaust brake also reduces stress on the engine by helping to slow down its speed when going downhill, which can help improve fuel efficiency and lower overall maintenance costs over time. Additionally, the exhaust brake system can provide increased control while driving downhill in slippery or icy conditions by slowing down your vehicle’s speed without having to use traditional brakes which could cause skidding or sliding due to decreased traction from wet roads or snow-covered surfaces.

Common Issues with the 6.7 Cummings’ Exhaust Brakes

Leaking vacuum lines, faulty sensors or switches, clogged intake valves and worn out diaphragms are all common issues that can affect performance of your 6 . 7 Cummins’ Exhaust Brakes system . Leaks in vacuum lines can cause air to escape from the system resulting in reduced efficiency and poor performance . Faulty sensors or switches can also cause problems with performance by not sending accurate signals to control valves . Clogged intake valves will reduce airflow into the engine resulting in poor performance or reduced efficiency . Finally worn diaphragms within valves may cause air leaks which will affect performance as well .

Maintenance Tips for Keeping the 6 . 7 Cummings’Exhaust brakes Working Properly

To ensure optimal performance from your 6 . 7 Cummins’ Exhaust Brake System , it is important to perform regular maintenance checks including inspecting valves and diaphragms for leaks and cracks , checking wiring harness connectors for loose connections or corrosion , as well as inspecting sensors and switches regularly for proper operation . It is also important to check oil levels regularly since low levels can lead to poor performance from an exhaust brake system . Finally , remember to replace any worn out parts immediately if needed as this can help prevent costly repairs later on .

Troubleshooting Common Issues with The6.7Cummings’Exhaust brakes

If you experience any noise when engaging your exhaust brake system , check vacuum lines , valves and diaphragms for possible leaks or cracks causing air leaks into the system which could be creating noise when engaged . If you notice poor performance from your system , check intake valves and sensors for clogs or improper operation respectively since these could be causing airflow restriction resulting in reduced power output . If you are experiencing uneven power output then check wiring harness connectors for loose connections , corrosion etc., since these could be preventing accurate signals from being sent between components thus affecting power output .

Cost Considerations When Purchasing anExhuastbrakeSystemfor6.7CummingsEngines

When buying an exhaust brake system for a 6 . 7 Cummins engine , there are several cost considerations that must be taken into account including cost of the actual system itself , installation costs (if needed) , replacement parts & maintenance costs and fuel savings over time if applicable depending on usage rate & environment driven through etc., To get a better idea of what each option may cost upfront it is recommended that you do some research online before making a purchase decision so that you are better informed about what fits best within your budget range & needs overall !

Alternatives To Using AnExhuastbrakeSystemon6.7CummingsEngines

If you do not wish to install an exhaust brake system onto your 6 . 7 Cummins engine then there are several alternatives available that may help reduce wear & tear on traditional brakes such as using higher grade motor oil (which increases lubrication) & installing upgraded braking systems etc., Additionally , other methods such as downshifting & idle control systems may also help reduce reliance on traditionally used brakes over time depending upon usage rate & environment driven through overall !
