What is a Core Charge?

A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.

30 Day Core Charge Hold

You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.

The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.

The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.

All fluids must be drained.

If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.

Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

The Exhaust Gas Recirculation (EGR) valve is a crucial component in modern internal combustion engines, particularly in diesel engines. Its primary function is to reduce nitrogen oxide (NOx) emissions, which are harmful pollutants that contribute to smog and air quality deterioration. Understanding what an EGR valve is and how it works can help you appreciate its role in maintaining engine efficiency and complying with environmental regulations.

What Is an EGR Valve?

The EGR valve is a mechanical device that controls the flow of exhaust gases from the engine's exhaust manifold back into the intake manifold. By recirculating a portion of the exhaust gases into the combustion chamber, the EGR valve helps lower the combustion temperature, thereby reducing the formation of NOx emissions.

How Does an EGR Valve Work?

  • Operation

    • The EGR valve operates by opening and closing at specific times to allow a measured amount of exhaust gas to enter the intake manifold. This process is controlled by the engine control unit (ECU), which uses various sensors to determine the optimal timing and amount of exhaust gas to be recirculated based on engine load, speed, and temperature.

  • Reduction of NOx Emissions

    • NOx emissions are primarily formed at high combustion temperatures. By introducing exhaust gases back into the combustion chamber, the EGR valve helps lower the peak combustion temperature. This reduction in temperature decreases the formation of NOx, making the engine more environmentally friendly.

  • Combustion Efficiency

    • The introduction of exhaust gases dilutes the incoming air-fuel mixture, leading to a slower and more controlled combustion process. This not only reduces NOx emissions but also improves overall combustion efficiency. A more efficient combustion process can enhance engine performance and fuel economy.

  • Types of EGR Valves

    • There are two main types of EGR valves—pneumatic and electronic. Pneumatic EGR valves are operated by vacuum pressure, while electronic EGR valves are controlled by the ECU through electrical signals. Modern vehicles primarily use electronic EGR valves due to their precision and reliability.

  • Components of an EGR System

    • The EGR system typically includes the EGR valve, EGR cooler, and associated sensors and actuators. The EGR cooler helps lower the temperature of the recirculated exhaust gases, further enhancing the effectiveness of the EGR system in reducing NOx emissions.

  • Maintenance and Issues

    • Regular maintenance of the EGR valve is crucial for ensuring its proper function. Common issues with EGR valves include clogging due to carbon buildup, sticking valves, and faulty sensors. Symptoms of a malfunctioning EGR valve include rough idling, decreased engine performance, increased fuel consumption, and illuminated check engine light.

Maintaining the health of your EGR valve is essential for optimal engine performance and compliance with emission standards. Regular inspections and timely cleaning or replacement can prevent issues and ensure that your vehicle remains in good working condition.

In conclusion, the EGR valve plays a vital role in reducing NOx emissions by recirculating exhaust gases back into the combustion chamber. This process lowers combustion temperatures, improves combustion efficiency, and helps meet stringent environmental regulations. Understanding the function and importance of the EGR valve can help you maintain your vehicle’s performance and contribute to a cleaner environment. Regular maintenance and timely repairs are crucial for the longevity and efficiency of the EGR system.

By recirculating a portion of exhaust gases, it lowers combustion temperatures and reduces harmful NOx emissions.

Failure can result in poor fuel economy, increased emissions, rough idling, engine hesitation, or fault codes.

A sticking valve may cause engine surging, loss of power, black smoke, or erratic idle behavior.

Excessive carbon deposits can block the valve, restricting exhaust flow and impairing its ability to regulate emissions.
