It features some of the latest engine technology such as direct fuel injection, sintered camshaft lobes, thin-walled engine block, variable valve timing and lift for intake and exhaust valves, downstream oxygen sensors, exhaust manifold integrated into the cylinder head, exhaust gas recirculation and cooling, distributors coil-on-plug ignition ...
Gasoline direct injection (GDI), also known as petrol direct injection (PDI), [1] is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. This is distinct from manifold injection systems, which inject fuel into the intake manifold (inlet manifold).
This is due to the fact that the fuel hits the intake valves on the way to the combustion chamber, allowing the detergents in the fuel to keep them clean. However, carbon build-up on intake valves is a problem for engines with direct injection only, as the fuel is injected directly into the combustion chamber.
It is related (through several evolutions of engine families) to the EA827 series, indirect-injection diesels, 16 valves, and five-cylinder gasoline engines. Naturally aspirated direct-injection variants are known as Suction Diesel Injection, abbreviated to SDI. Many are offered with a turbocharger, and known as Turbocharged Direct Injection (TDI).
The engine also had a vacuum actuated variable intake manifold, controlled by the ECU via a valve part of the engines vacuum system. The valve is opened and closed depending on engine load, engine speed and throttle position. This allows the engine to take advantage of pressure waves created by the intake valves opening and closing.

This 2.8 L (171 cu in) engine produced 150 kW (201 hp), and mostly replaced the two-valve engines, except for in North America where an updated version of the two-valve engine was used in the Golf and Jetta from 2000 to 2002. A 3.2 L (195 cu in) EA390 version of the 4 valve engine was introduced in the 2001 Volkswagen New Beetle RSi model
