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 ...
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 first class of turbo code was the parallel concatenated convolutional code (PCCC). Since the introduction of the original parallel turbo codes in 1993, many other classes of turbo code have been discovered, including serial concatenated convolutional codes and repeat-accumulate codes. Iterative turbo decoding methods have also been applied ...
The first-generation NX is available in three powertrains; which are designated NX 200t/300, NX 300h, and NX 200. The NX 200t/300 is powered by a 2.0-liter 8AR-FTS turbocharged four-cylinder direct injection engine that can run on both Otto and Atkinson cycles. This engine has Lexus' Economy with Superior Thermal Efficient Combustion (ESTEC ...
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.

A 3.0L displacement version, with common-rail fuel injection, four-valve-per-cylinder heads, and 160 hp (119 kW) (wastegate turbo), is the electronic version of the Power Stroke. It has only the block and connecting rods in common with 2.8L Power Stroke. The 4.5L Power Stroke was a V6 Power Stroke with the same turbo design as a 6.4L.
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.
