Which engine has an exhaust gas flap (EGF)?

The DD13 High Power engine is specifically designed to include exhaust gas flaps (EGF) as one of its features. The purpose of the exhaust gas flap is to help regulate exhaust gas flow and enhance engine performance by improving the efficiency of the exhaust system, particularly during various operational conditions. The implementation of EGF in the DD13 High Power variant aids in optimizing exhaust temperatures and emissions, which is essential for meeting regulatory standards and achieving better fuel efficiency under load.

In contrast, other engine options may not have the same requirements or specifications that necessitate the use of an exhaust gas flap. The design and tuning of the DD13 High Power engine target specific performance traits, making it suitable for applications that demand a higher output and efficiency, which the EGF supports. Thus, it stands out among the options as having this particular technology.
