EGR valve the top of box on top of the inlet manifold of a Saab H engine in a 1987 Saab 90. In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO x) emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. [1]
It is a family of 3-cylinder and 4-cylinder diesel engines featuring modular diesel engine system (MDB (Modularer Diesel Motor Baukasten)), [3] [4] [5] with dual-loop EGR system, with high pressure EGR and a cooled low-pressure EGR loops; variable valve train (VVT) with a camshaft adjuster, Bosch CRS 2-20 2000 bar common rail injection system ...
All Subaru EJ engines have a 1-3-2-4 firing order, which, given the longer exhaust runners on cylinders 2 and 4 causes the characteristic "subaru boxer rumble". Some of the 2005 and later Subaru vehicle Engines (especially the turbo charged engines) are using CAN bus as their sole Vehicle/Vessel speed input channel.
The 2.5-litre 6G73 is a 24-valve SOHC design with two valves running off a single cam lobe on the exhaust valves using a forked rocker arm and each intake valve actuated with two cam lobes, with a smaller bore than the 3.0L version of the same block. Bore and stroke are 83.5 mm × 76 mm (3.29 in × 2.99 in); it is a 60-degree V6 and weighs ...
The crankcase air outlet, where the PCV valve is located, is generally placed as far as possible from the crankcase breather. For example, the breather and outlet are frequently on opposite valve covers on a V engine, or on opposite ends of the valve cover on an inline engine. The PCV valve is often, but not always, placed at the valve cover ...
The 2007 Porsche 911 Turbo has twin variable-geometry turbochargers on its 3.6-litre horizontally-opposed six-cylinder gasoline engine. In 2007, Acura introduced the RDX with Variable Geometry Turbocharger following a (VFT) design. The 2015 Koenigsegg One:1 uses twin variable-geometry turbochargers on its 5.0-litre V8 engine, allowing it to ...
The Nissan QD engine, successor to the Nissan TD engine, was an inline four-cylinder overhead valve diesel produced from the mid-1990s through 2000, with a turbocharger used on three variants, the QD32ETi(Elgrand and Terrano) QD32T and Qd32Ti(intercooled) in Chinese Markets (Nissan Cabstar) .
The Smartstream G1.5 T-GDI (G4LH) is a turbocharged 1,482 cc (1.5 L) inline 4-cylinder engine with GDi from the Kappa family that carries a bore and stroke of 71.6 mm and 92 mm [12] respectively and a 10.5:1 compression ratio; it makes 160 PS (118 kW; 158 hp) at 5,500 rpm and 25.8 kg⋅m (253 N⋅m; 187 lbf⋅ft) of torque between 1,500 and ...
