Self Study Program 920253 – The Audi 1.4l TFSI Engine PDF free online

The 1.4l TFSI engine used in the A3 Sportback e-tron is from the EA211 series of 4-cylinder engines used by Audi worldwide. This is the first use of this engine in the North
American market.

It is derived from the EA111 series of 4-cylinder engines but has been further refined to be lighter, more fuel efficient, and reduce emissions. It is compactly dimensioned for vehicles using the cross-platform modular component set (MQB).

In some markets, a selective cylinder shut-down capability that enables two of the four cylinders to be shut down when driving situations allow is employed. However, in the North
American market this feature will not be used.

The 1.4l TFSI engine develops 147 hp (110 kw) and is coupled to the e-machine (Electro-drive Drive Motor V141) and six-speed DSG transmission 0DD.
