![]() ![]() These engines were manufactured till 2015. The EA888 Generation 2 fulfills greater emission requirements than the EA888 Generation 1 – Euro5 (CDNC engine) and ULEV 2. Furthermore, the 2.0TFSI engines for Audi applications were outfitted with the AVS system (CCZA, CCZB, CCZC, and CCZD engines) it’s a two-stage intake valve lift controller.Īfter 3,100 rpm, the mechanism changes the valve lift in two stages: 6.35 mm and 10 mm. A variable oil pump is used in this generation. In addition, low-friction thin piston rings, new pistons, and a new technology for creating cylinder wall surfaces were used. The diameter of the main journals was lowered by 6 mm for this reason (58 mm to 52 mm). The primary goal was to reduce friction and increase efficiency. The 2.0TSI EA888 Generation 2 debuted in 2008, with the same set of changes as the 1.8 TSI Gen-2. Further, as a compliance, the 2.0 TSI Gen1 with two lambda probe sensors complies with European pollution standards Euro 4 (CAWB, CAWA engines) and ULEV 2 (CCTA, CCTB engines) the CCTA variant has three lambda probe sensors and complies with Californian SULEV. The whole operation is managed by the Bosch Motronic MED 17.5 ECU. The compressed intake air is routed through the variable shape intake manifold made of plastic. With a maximum boost pressure of 8.7 psi, the engine is turbocharged by the water-cooled and incorporated into cast iron exhaust manifold turbocharger KKK K03. The engine also includes electronic ignition with long-life spark plugs and four unique single spark coils. The low-pressure fuel pump, which is housed in a tank, distributes gasoline to the high-pressure pump, which provides up to 2,760 psi of fuel pressure to the six-hole fuel injectors.Ī four-lobe cam on the exhaust camshaft drives the high-pressure injection pump. The 2.0 TSI Gen1 features direct injection with homogenous mixing. The variable intake valve timing system is installed on the intake camshaft. The timing chain drives the intake and exhaust camshafts, which are located on top of the head. ![]() The intake valve has a diameter of 34.0 mm, the exhaust valve has a diameter of 28.0 mm, and both valves have a stem diameter of 6 mm.įor valve clearance adjustment, the valvetrain uses low-friction roller finger cam followers and hydraulic tappets. Each cylinder has two intake and two exhaust valves. The aluminum 16-valve cylinder head of the 2.0TSI is comparable to the head of the 1.8TSI. The engine block is outfitted with two counter-rotating balancing shafts that are chain-driven. The new forged steel crankshaft with a stroke of 92.8 mm increased displacement while keeping the bore size same.įurthermore, the engine’s short connecting rods and other pistons reduce the compression ratio to 9.6:1. The 2.0l engine, like the 1.8TSI, features a cast-iron cylinder block with 88 mm cylinder spacing and 220 mm height. Maximum Torque: 280 lb-ft at 1,500 – 5,500 RPMĬAWA, CAWB, CBFA, CCTA, and CCTB are the codes for the 2.0TSI EA888 Generation 1.Valvetrain: DOHC four valves per cylinder.The final VW 2.0TSI engine has three versions. This two-liter variant, like the 1.8 TSI engine, went through a number of revisions during manufacture. It was released to replace the existing EA113 family’s 2.0 TSI engines. In March 2008, manufacture of the 2.0 TSI engine began. The Volkswagen 2.0 TSI / TFSI EA888 is a 2.0 liter four-cylinder gasoline turbocharged engine based on the EA888 series’ 1.8 TSI/TFSI. What are VW/Audi 2.0 TSI/TFSI EA888 Engines? This engine is an evolution of its 2.0T engines and where we have been over time with those designs – but there are still many questions about it. Throughout the mid 2000s, the streets are filled with difference machines to impress different crowds in different strokes and one of those is the the VW/Audi EA888 Gen 3 engine. ![]()
