An internal wastegate is a built-in bypass valve and passage within the turbocharger housing which allows excess exhaust pressure to bypass the turbine into the downstream exhaust. Control of the internal wastegate valve by a pressure signal from the intake manifold is identical to that of an external wastegate.
The wastegate was designed to eliminate the lag between the driver pressing the accelerator and the turbine increasing its revolutions. Once the turbine was at its maximum revolutions, the wastegate helped regulate the flow of hot gas from the core to the power-turbine, thus increasing or decreasing the power output to the gearbox far quicker ...
The second-generation Toyota CT26 used a twin entry turbine housing with dual wastegate ports. It was fitted to the second generation Toyota Celica GT-Four (ST185) as well as the Toyota MR2 Turbo (SW20). The intake charge is cooled by an air-to-air intercooler either top-mounted in the Celica or side-mounted in the MR2.
This design has a lower flow rate compared to VNT types so a wastegate may be incorporated with this design. [5] VGTs may be controlled by a membrane vacuum actuator, electric servo, 3-phase electric actuation, hydraulic actuator, or pneumatic actuator using air brake pressure. Unlike fixed-geometry turbines, VGTs do not require a wastegate. [6]
The turbine housings direct the gas flow through the turbine section, and the turbine itself can spin at speeds of up to 250,000 rpm. [28] [29] Some turbocharger designs are available with multiple turbine housing options, allowing a housing to be selected to best suit the engine's characteristics and the performance requirements.
The turbine housing was changed to a .84 A/R and a wastegate was added halfway through the 1999 model year. The 1999 engine also received 140 cc (8.5 cu in) injectors, up from 120 cc (7.3 cu in) in the early model engine.
A screamer pipe is a type of exhaust configuration fitted to some automotive turbocharged petrol engines with an external wastegate set-up, which vents the waste exhaust to the atmosphere through a separate un-muffled pipe, rather than back into the main exhaust track. This exhaust setup is known for its loud noise.
Its maximum turbine speed is 2550 s −1, [5] and it delivers a boost pressure of up to 170 kPa. [6] Daimler-Benz did not equip the OM 617 A with an intercooler. Still, the turbocharger improves the engine's thermal efficiency, resulting in a BSFC of 245 g/(kW·h), an improvement of ca. 20 g over the naturally aspirated version. [ 7 ]
