Does the Volkswagen EA839 Engine Burn Oil?

[DelAndrew]

Here is the relevant introduction about the Volkswagen EA839 engine: 1. Top-mounted fuel injectors: The top-mounted fuel injector structure has changed the FSI architecture that Audi has been operating for many years. Since abandoning the five-valve technology, all of Audi's engines have adopted the FSI architecture, which features side-mounted fuel injectors + intake flaps (LBK) + recessed pistons. This system essentially generates high-tumble mixture gas under medium and low loads, induced by the intake flap LBK, with the assistance of the intake port, combustion chamber, and piston top design. In reality, the side-mounted fuel injectors require the engine to use high tumble to achieve good mixing, which is a limiting factor. The advantage is that the cylinder spacing can be reduced. Due to Audi's unique front-wheel-drive longitudinal layout, the requirements for engine size are very strict, so the FSI has always catered to the vehicle's design requirements. 2. Layout: That is, the hot end is in the center of the V-type, firstly to improve turbo response, and secondly to allow the structure to accommodate both single turbo and Biturbo. Since the intake and exhaust are reversed, all mechanical structures and cooling systems of the engine must be redesigned. The technology that can be inherited from the EA837 is very limited. The HSI is completely developed for sportiness and driving pleasure, sparing no cost for the engine's response, and from a design and technical perspective, it can truly be called a conscientious effort.
