EGR Delete / EGR bypass

Exhaust gas recirculation (EGR) is an emission control technology that reduces nitrogen oxide (NOx) emissions from internal combustion engines.

Benefits of EGR Deletion / removal

EGR Delete software presents an opportunity for cost savings in repair expenditures and fuel usage. As a pioneer in EGR Removal and EGR Bypass software, VZ Tuning excels in the elimination of EGR functionality across diverse ECU models. Merely disabling codes associated with an unplugged ECU falls short of the ideal solution. It is crucial to deactivate the EGR valve to avert exhaust gas recirculation, thereby safeguarding the engine's operational efficiency.

  • Restoration of engine power
  • Improved fuel efficiency
  • Reduced emissions in comparison to defective EGR systems, which lead to significantly higher soot accumulation
  • Potential prevention of DPF failure by capturing soot in the DPF trap
  • Potential avoidance of costly EGR replacements, which could amount to thousands of Rands
how does EGR valve function:
  • The EGR Valve facilitates a connection from the exhaust manifold to the intake manifold, enabling the recirculation of exhaust gases.
  • A solenoid governs the EGR valve, with its operations overseen by the Electronic Control Unit (ECU).
  • The ECU regulates the solenoid through a duty request cycle to facilitate the opening of the valve, allowing for the recirculation of exhaust gases.
  • The Manifold Absolute Pressure sensor quantifies the surplus gas volume, providing feedback to the ECU for control purposes.
EGR valve problem:

The EGR valve, which operates in conjunction with burnt exhaust gases, tends to accumulate high levels of soot over time. This soot buildup can lead to the formation of carbon deposits in the vicinity of the valve, causing it to become stuck in different positions. To optimize engine performance, the EGR valve is best kept closed, fostering a closed-loop system that enables the turbo system to pressurize effectively. A malfunctioning EGR valve can disrupt this closed-loop system, creating an open-loop scenario for the turbo. In such cases, feedback is directly provided to the intake manifold, potentially resulting in issues with boost pressure, as well as reductions in power output and fuel efficiency.
