![]() This also makes temporary boosting of the charge pressure (overboost) possible under acceleration.įresh air is used in addition to oil and water to cool the turbocharger. The modifying signals include the intake air temperature, engine temperature, engine speed and atmospheric pressure. The main input signals for the wastegate control unit are the charge pressure, throttle flap position and the knocking tendency. Numerous parameters are taken into account in this process. ![]() The electronically controlled wastegate (exhaust relief valve) allows the charge pressure to be controlled even more precisely and flexibly while optimising responsiveness, especially when accelerating from partial load. With a maximum charge pressure of 2.1 bar (1.9 bar in the basic version), the 2.0-litre turbo engine is also the top performer in this respect. This provides the best basis for continuing to ensure our high quality level even as the technology becomes more complex," says Emmerich Schiller, COO and member of the Board of Management at Mercedes-AMG GmbH. To achieve this, we created the ideal working conditions in a bright, precisely organised and clean environment for our employees. The result is an ultra-modern production process that places the focus on people. "We have completely revised the principle of "One Man, One Engine" for assembly of the M 139. It safeguards and improves the quality of the engines and production processes using innovative and digital technologies. This excels with maximum flexibility, and is transparent and highly efficient. On the road to implementing Industry 4.0, AMG's hand assembly operation likewise follows the vision of "smart production". On the first floor of the AMG engine manufactory in Affalterbach, a completely newly designed production line was installed in which Mercedes-AMG has brought the "One Man, One Engine" principle to a new level together with Industry 4.0 methods that incorporate the latest findings in ergonomics, materials handling, quality assurance, sustainability and efficiency. The new engine is entirely assembled by hand. Not only is the output per litre unrivalled for a turbocharged engine, the high level of efficiency also demonstrates that the internal combustion engine still has further potential," says Tobias Moers, Chairman of Mercedes-AMG GmbH. With the M 139, we have once again impressively demonstrated the engine expertise of Mercedes-AMG. And we succeeded with a number of sometimes revolutionary solutions. This fundamentally new four-cylinder presented us with the challenge of doing even better. "We already set the benchmark in the segment with the preceding engine. Moreover, the high maximum engine speed (up to 7200 rpm) confirms the M 139 as a sports engine. The increasing torque at higher rpm makes the engine more free-revving. The engine developers were also able to realise a dynamically increasing torque curve in the lower engine speed range, thereby improving agility. With this configuration, the AMG engineers have achieved a power delivery similar to that of a naturally aspirated engine for an even more emotive driving experience. To this end the torque curve was carefully balanced ("torque shaping"): The peak torque of 500 newton metres (480 newton metres for the basic version) is available in a range of 5000-5250 rpm (4750-5000 rpm in the basic version). This product policy logic has already proved successful in the V8-powered AMG Performance models, and more closely meets customer wishes.Īpart from its performance figures, the new engine impresses with its immediate response. The four-cylinder available in two output versions will ensure agile performance for the compact models of Mercedes-AMG: with 310 kW (421 hp) as the S-model and with 285 kW (387 hp) in the basic version. The new, highly efficient powerpack is produced on an innovative production line in Affalterbach, on the "One Man, One Engine" principle. With an output per litre of up to 155 kW (211 hp), the new Mercedes-AMG high-performance turbo engine even ranks ahead of many well-known super-sports car engines. Maximum torque has also increased from 475 to up to 500 newton metres. With this engine, Mercedes-AMG has even exceeded the previously most powerful M 133 by 30 kW (41 hp). Four wins: with an output of up to 310 kW (421 hp), the completely newly developed Mercedes-AMG 2.0-litre M 139 engine is the world's most powerful turbocharged four-cylinder engine in series production.
