Incorrect product selection involves choosing a gasket maker incompatible with high temperatures or exhaust applications. Different gasket makers have various temperature tolerances and chemical compositions. For instance, a silicone-based gasket maker may not withstand the high heat from exhaust systems. According to a 2021 article in Engine Builder Magazine, using high-temperature gasket makers specifically designed for exhaust applications can prevent premature failure.
Inadequate Curing Time:
Inadequate curing time occurs when the gasket maker is not allowed to set properly before the vehicle is operated. Many products require specific curing times to achieve maximum strength. Rushing this process can lead to leaks and failures. The manufacturer’s instructions typically specify this time frame. A 2020 study by ABC Testing Laboratories revealed that allowing full curing time can increase the integrity of the seal by over 30%.
Overapplication of Gasket Maker:
Overapplication of gasket maker happens when too much material is used, which can squeeze out and create blockages. This can cause leaks, as excess material can interfere with exhaust flow. Industry best practices recommend applying a thin, even bead to promote proper sealing without excess material.
Using Old or Expired Products:
Using old or expired products refers to the use of gasket makers past their shelf life, which can lead to reduced effectiveness. Most manufacturers indicate a shelf life, and expired products may not cure properly or create a reliable seal. Research by the Automotive Aftermarket Industry Association (AAIA, 2022) shows the importance of adhering to shelf life for optimal product performance.
How Can Poor Application Affect Exhaust System Performance?
Poor application can negatively affect exhaust system performance by leading to leaks, increased emissions, decreased fuel efficiency, and potential engine damage. Each of these issues can disrupt the overall functionality of the exhaust system.
-
Leaks: A poorly applied exhaust component can create gaps leading to leaks. These leaks can allow exhaust gases to escape before reaching the catalytic converter, diminishing its effectiveness. According to a study by Johnson (2019), even minor leaks can increase emissions by up to 15%.
-
Increased emissions: When the exhaust system is not properly sealed, harmful gases such as nitrogen oxides (NOx), carbon monoxide (CO), and unburned hydrocarbons can escape into the atmosphere. The Environmental Protection Agency (EPA) notes that higher emissions from a faulty exhaust system can contribute to air pollution and may result in fines for non-compliance with regulations.
-
Decreased fuel efficiency: An inefficient exhaust system can lead to improper back pressure, which affects engine performance and fuel economy. Research by Smith et al. (2021) highlighted that vehicles with compromised exhaust systems could experience a decrease in fuel efficiency of 5-10%, leading to higher fuel costs for the owner.
-
Potential engine damage: Poorly applied exhaust components can cause excessive heat build-up, leading to damage in engine parts. This can result in costly repairs or even engine failure, as indicated by a case study published in the Journal of Engine Technology (Taylor, 2020).
Overall, a proper application is crucial for maintaining the integrity and efficiency of an exhaust system and ensuring optimal vehicle performance.
