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]
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 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 ...
The 2.9 TFSI engine is a twin-turbo charged high performance variant with shorter stroke. Petrol versions of S6 and S7 (C8), like their diesel powered counter parts, feature an electric supercharger powered by the 48V mild hybrid system in their 2.9 TFSI engines. identification parts code prefix:???, ID codes: CWGD, CZSE/DR, DECA, DKMB
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.
[69] [70] The Chevrolet division of GM built the Turbo Titan series of concept trucks with turbine motors as analogs of the Firebird concepts, including Turbo Titan I (c. 1959, shares GT-304 engine with Firebird II), Turbo Titan II (c. 1962, shares GT-305 engine with Firebird III), and Turbo Titan III (1965, GT-309 engine); in addition, the GM ...
