In an internal combustion engine, twin-turbo is a layout in which two turbochargers are used to compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine). The most common layout features two identical or mirrored turbochargers in parallel, each processing half of a V engine 's produced exhaust through ...
The VG30DETT is an iron block/aluminum head twin-turbo, twin intercooler 2,960 cc (3.0 L; 180.6 cu in) version first seen in the 1987 MID4-II concept. Producing 330 PS (325 bhp; 243 kW) in the MID-4 and coming in at a weight of 237 kg (523 lb), it was the last of Nissan's DOHC belt driven 4 valve per cylinder turbocharged engines put into ...
Front-mounted air-to-air intercooler Top-mounted air-to-liquid intercooler (the silver cuboid-shaped part) on a BMW S55 turbocharged engine. An intercooler is a heat exchanger used to cool a gas after compression. [1] Often found in turbocharged engines, intercoolers are also used in air compressors, air conditioners, refrigeration and gas ...
Below this rpm, both exhaust and air inlet of the secondary turbo are closed. Being individually smaller they have reduced lag [16] and having the second turbo operating at a higher rpm range allows it to get to full rotational speed before it is required. Such combinations are referred to as a sequential twin-turbo. Sequential twin-turbo ...
1JZ-GTE (non VVT-i) in a 1991 Toyota Mark II 2.5GT Twin Turbo Third Generation 1JZ-GTE VVT-i transplanted into a 1989 MX83 Toyota Cressida. The 1JZ-GTE is a twin-turbocharged version of the 1JZ, produced from 1990 to 2007. The first generation 1JZ-GTE employs twin CT12A turbochargers arranged in parallel and blowing through a side-mount or ...
Mazda went back to the 4 port intake design similar to what was used in the '74–'78 13B. In '86–'88 engines the twin-scroll turbocharger is fed using a two-stage mechanically actuated valve, however, on '89–'91 engines a better turbo design was used with a divided manifold powering the twin-scroll configuration. For engines manufactured ...
The EJ20X and EJ20Y engines were equipped with Subaru's ‘Dual Active Valve Control System’ (‘Dual AVCS’) which provided variable intake and exhaust valve timing. The Legacy GT, the EJ20X engine was fitted with a twin-scroll IHI VF38 turbocharger; the EJ20Y engine, however, had a larger twin-scroll Mitsubishi TD04 HLA 19T turbocharger.
It is turbocharged and intercooled with a power output of 250 PS (184 kW; 247 hp) at 6000 rpm and 350 N⋅m (260 lb⋅ft) of torque at 2400–5000 rpm. It is equipped with Bosch Motronic 4.3 engine management. The 850 R models come with a TD04HL-16T turbo, S70 R and V70 R models come with a TD04HL-18T turbo. Applications:
