An external wastegate requires a specially constructed turbo manifold with a dedicated runner going to the wastegate. The external wastegate may be part of the exhaust housing itself. External wastegates are commonly used for regulating boost levels more precisely than internal wastegates in high power applications, where high boost levels can ...
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.
The limited-production 1989 Shelby CSX-VNT, with only 500 examples produced, was equipped with a 2.2-litre Chrysler K engine with a Garrett turbo called the VNT-25 (because it used the same compressor and shaft as the fixed-geometry Garrett T-25). In 1991, Fiat incorporated a VGT into the Croma's direct-injected turbodiesel. [2]
The Fusion replaced the Mondeo for the Latin American markets—except in Argentina (where the current European Mondeo is available) and in the United States and Canada (where it superseded the then mid-size Taurus and the compact Contour). The Fusion is positioned between the compact Ford Focus and the full-size Ford Taurus. [4]
A 3-port solenoid-type boost controller A 4-port solenoid-type boost controller (used for a dual-port wastegate). The purpose of a boost controller is to reduce the boost pressure seen by the wastegate's reference port, in order to trick the wastegate into allowing higher boost pressures than it was designed for.
The anti-lag system (ALS) is a method of reducing turbo lag or effective compression used on turbocharged engines to minimize turbo lag on racing or performance cars. It works by retarding the ignition timing and adding extra fuel (and sometimes air) to balance an inherent loss in combustion efficiency with increased pressure at the charging side of the turbo.
A 1.5 L version of the EcoBoost engine family was first unveiled in the 2014 Ford Fusion as a downsized version of the 1.6 L EcoBoost engine. [34] The downsized displacement is a result of Chinese vehicle tax regulations which tax vehicles with engine displacements of 1.5 L or less at lower rates.
It is a development of the IDI Mazda 2.2L normally aspirated, later 2.5L NA and Turbo and later 2.9L NA, with Bosch common-rail direct injection and a variable geometry turbocharger. The WLC engine code is a Mazda engine code, not being changed for use in the Mazda B-Series clone Ford Ranger.
