At the end of the compression, both the Gen.3 and Gen.3B engines broadly show similar levels of pressure. The additional use of a turbocharger helps support relatively high engine loads with the short valve opening contour and the lower valve lifts, enabling the good efficiency of the EIVC-based process over a wider load range.
The range of engine performance is very broad. Mail your ECU to APR, 4800 U.S. Hwy 280 W, Opelika, AL 36801, USA, and include the last 6 of your VIN on the outside of the box. Justin.Lau | The EA888 Gen.3B resolves this trade-off through the use of the Audi valvelift system on the intake side. Click to enlarge.
VW/Audi EA888 Gen 3 (MQB/MLB) Engines Explained So the new VW/Audi EA888 Gen 3 motor has been out for quite some time, but I still get questions on what is new with this engine. New cooling system with electronic control of the coolant. I'm looking at buying an '18 2.0T Atlas and have been doing some research on the engine, which appears to be the EA888 Gen 3b.
There is also an evolution of the Gen 3 motor that utilizes their B-Cycle Combustion process (now called Gen.3B). Behind Audi’s new “rightsized” efficient EA888 Gen.3B family Audi’s new “rightsized” 2.0L Gen.3B engine maintains the displacement of the 2.0L Gen.3 and delivers the power of the 1.8L TFSI with the fuel consumption of the 1.4L TFSI. However, we are all a bit spoiled and don’t want to give up any power. Updated intake manifold with stronger runner flaps to handle higher boost pressures; and hopefully fewer failures than what we have seen on the Gen 2 motors. Click to enlarge. The basic Gen.3B idea is to combine a shortened compression with a normal—i.e., longer in proportion to the compression—expansion phase to attain significant gains in efficiency. For specific information and questions contact an APR representative. | Some products may not comply with local laws, and some may affect parts of the manufacturer’s warranty. First introduced in the 2009 CC, the EA888 continued Volkswagen’s move toward smaller, turbocharged engines that offer the fuel economy benefits of downsizing with the power of a larger-displacement unit. Thanks for the detailed response.
The engineers opted for the modified Miller firing process. An increase of the compression ratio from ε = 9.6 to ε= 11.7 by decreasing the combustion chamber volume. number is issued, this product will be updated to 50-state legal status. All Right Reserved. The engine, featuring a new combustion method based on the Miller cycle, will be used for the first time in the next generation of the A4. APR Stage 1 is available for 87 AKI, 91 AKI, 93 AKI, 100 AKI, 104 AKI, and E60-E85 fuel grades in North America, and 95 RON, 98 RON, 104 RON, 108 RON, and E60-E85 in the Rest of the World. Michael Grigo, Copyright© 2020 by APR, LLC. Please note, our E85 software is not a full flex fuel program. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered! Reading reviews of previous generations of this engine leads me to believe that it frequently suffers from timing chain issues. Follow this link for a quick summary. 15 May 2015 at 07:32 AM.

VW/Audi EA888 Gen 3 (MQB/MLB) Engines Explained. Once testing is complete with California, and an E.O. This is made possible through APR's optimization of the factory engine management system to take full advantage of the engine's capabilities, without needing any end user adjustment. A good starting point is understanding the differences between the FSI (or EA113) engine and the TSI (EA888). https://www.alexsautohaus.com/blog/whats-the-difference-between-fsi-and-tsi/. The 2.0TSI EA888/3 or Gen3 was designed to be lighter and more efficient. Audi made a number of design changes to the EA888 Gen.3 engine to realize the Gen.3B. It is used on car platforms and brands of the most diverse group. The Miller cycle uses a higher expansion ratio than compression ratio (i.e., over-expansion) obtained by either early or late closing of the intake valves (EIVC and LIVC, respectively), resulting in a smaller effective compression stroke; combustion and expansion proceed normally. How to Purchase - APR Software Upgrades are available through Authorized APR dealers. Mono Scroll or Twin Scroll? Contributing factors include the vehicle condition, vehicle setup, dyno type, dyno setup, environmental factors, fuel quality, and more. However, short intake durations and high compression ratios limit high engine loads due to reduced filling and increasingly strong knock limits. Click to enlarge. Audi says that the new 2.0L TFSI is the first representative of direct-injection gasoline engines based on “right-sizing” rather than “down-sizing”. When describing fuels, the North American Region (NAR) uses the Anti-Knock Index (AKI), (RON+MON)/2, or (R+M)/2.
Our 36,000 mile warranty is the best in the business! After you have completed this self study programme you will be able to answer the following questions: Click to enlarge. The visualization on the right show the effect of the changes to the Gen.3B engine in maintaining charge motion. Our performance software upgrade is available in multiple stages with optional features.
