What are the differences between the second and third generation EA888?
1 Answers
Here is an introduction to the differences between the second and third generation EA888: 1. Different engines: The third-generation EA888 engine has made a significant change by integrating the exhaust manifold directly into the cylinder head. Due to the extremely high working temperatures of the exhaust manifold and its more complex structure, this poses a considerable challenge to the stability of the cylinder head. To address this, the cooling system within the cylinder head has been improved, with higher flow rates ensuring better heat dissipation efficiency (otherwise, the coolant in this area could even risk boiling). 2. Injection system: Volkswagen's new dual injection system not only enhances power performance but also reduces emissions (the stringent European emission standards now place significant pressure on all manufacturers). Of course, the dual injection system combined with higher direct injection pressure (increased from the previous 150Bar to 200Bar) imposes higher demands on the stability of the fuel system, which is undoubtedly a challenge for Volkswagen's engineers.
