Humphrey Valves are becoming a popular tool to see the adoption of automated manual transmissions (AMTs) and safety technology that is supported by electronic controlled braking systems and the vehicle air system in a commercial environment. There is a list of AMTs that are available on the market that use a mechatronic shifter with the technology of electronic controls that offer high power density. The engine’s air compressor controls the air that the AMTs provide. Additionally, a majority of controls used for trucks utilize a number of electronic operated solenoids that clean and dry air that is not common in traditional manual brake valves. As a result, AMTs are sensitive to oil contamination and small particles.
With our knowledge in the industry, we included a list of things to look for when it comes to air contamination that can have a negative impact on connected vehicle systems. Remember to purchase your Humphrey Valves by viewing our products on our website and calling 1-800-282-4886.
The Signs of Poor Air Quality
There are early signs of poor air quality in a compressor and air dryer. These systems depend on properly functioning valves that includes solenoid valves for pneumatic and emissions controls.
“These components have very tight tolerances, and if there’s too much of that ‘toxic brew’ of contaminants, engine oil, and water, it leads to mechanical malfunctions due to fouling within valves, for example,” stated the director of marketing and customer solutions for Bendix. “That’s actually how many customers first realize there’s a problem with the air system: Drivers will report noticeable performance changes, like malfunctioning brake valves or an AMT not engaging or operating as smoothly as expected.”
Additional signs to look out for include a high amount of oil mixed in water that is seen when draining an air system tanks is completed. The importance of replacing air dryer cartridges more often is highly recommended.
Helpful Compressor Facts
Designers made a compressor to collect oil to lubricate the piston. The amount of oil that passes through will depend on a number of different factors that includes the duty cycle, age, operating temperature and the engine. A compressor that is in good shape can pass a high amount of oil every year. In contrast, an inefficient compressor can pass more oil than that of which is needed.
As the oil moves through the compressor piston, moisture sets into the engine through the air intake system of a truck that causes emulsions to accumulate in the air system. If a higher amount of oil that passes through a compressor in addition to ambient temperatures takes place, carbon buildup in the unloading valves can cause a malfunction of the unloading system. A combination of water and oil can stop the air passage in the discharge line.
