Toyota Supra EGR Valve
The EGR Valve in the Toyota Supra sends a controlled amount of exhaust gas back into the intake stream. This lowers combustion temperature and reduces nitrogen oxide emissions. The EGR Valve is a part that is installed on a passage linking the exhaust manifold with a passage from the intake manifold. An EGR Valve opens when the vehicle is at steady cruising or light acceleration. An inert exhaust will then enter the intake manifold, which results in displacing some of the oxygen. This prevents peak combustion temperatures of 2,500°F from taking place, which generates NOx. Due to controlled dilution by the EGR Valve, detonation in Supra engines is also prevented. At idle, wide-open throttle, and until coolant warms, the EGR Valve closes and prevents rough running or stalling. The flow can be controlled by a vacuum-operated diaphragm or by an internal electric motor. Sensors and solenoids ensure that the command is accurate such that the valve only functions when helpful. The EGR Valve works consistently to make each Toyota Supra comply with emission limits as well as work with the engine's performance, not affecting drivability. This is a clear indication of Toyota's balanced engineering thinking for Supra owners and Toyota environmental goals.

Toyota Supra EGR Valve Parts Questions & Experts Answers
- Q: What Are the Functions and Diagnostic Procedures for the EGR System and EGR Valve on Toyota Supra?A:EGR system works by allowing a portion of exhaust gas to mix with the intake gas to lower the combustion temperature and thus the generation of nitrogen oxides. The main component is the GR valve operated by EGR vacuum modulator, vacuum control vale for 1979-1981, VCV for 1979-1982, VSV for 1982 and later and BM VSV for 1979-1982 models. These systems differ in quite a way for instance 1980 models have two VCV valves and two EGR valves while one VCV valve opens due to the changes in the intake manifold vacuum. According to the model 1983 and the later models, the function of BVSV is regulated by the EFI computer that oversees the coolant temperature. At low engine temperature, both the BVSV and the EGR valve are shut; the recirculation of the exhaust gas is prevented but at the high temperatures, the opening of the BVSV allows the EGR valve to function under pressure changes. The checks include the peeping of filter in modulator for signs of damage or any deposits, checking of hoses for cracking and appropriate connection and checking of vacuum at the operating RPM. The procedures for 79 & 80 models include removing the hoses, application of vacuum and comparatively observing the performance of the engine when it comes to problems relating to EGR valve and its parts. For the 1982-1986 models, similar steps are carried out; such as checking the vacuum levels and ascertaining the status of the EGA valve. More tests in later models concern checking of the vacuum modulator and the VSV with differing actions for turbo and non-turbo models. In replacement of the components a detailed disconnection is done with labeling of hoses since they will be reattached in the similar position including EGR valve, BVSV and other similar components.
