3. Technological Innovations in Diesel Engines

  • 3-1. Introduction to OM 654 Engine

  • The OM 654 engine represents Mercedes-Benz's latest advancement in diesel technology, designed to meet future emissions legislation, particularly the Real Driving Emissions (RDE) standards. This four-cylinder diesel engine is notable for being the first all-aluminum construction from Mercedes-Benz, marking a significant step forward in efficiency.

  • 3-2. Key Features of OM 654

  • The OM 654 engine introduces several key features that distinguish it from previous models. These include a focus on efficiency and emissions reduction, achieved through advanced engineering and innovative design approaches, ensuring that the engine remains compliant with stringent regulations.

  • 3-3. Multiway Exhaust Gas Recirculation

  • Multiway exhaust gas recirculation is a critical feature of the OM 654 engine. This system contributes to reduced emissions by recirculating exhaust gases back into the combustion chamber, which helps lower nitrogen oxide (NOx) emissions and enhance overall engine performance.

  • 3-4. Cold Start Efficiency

  • The OM 654 engine has been optimized for cold start efficiency. Mercedes-Benz has implemented insulation measures and improved catalyst coatings that eliminate the need for extensive engine temperature management during cold starts. This results in lower emissions and improved fuel efficiencies in short journeys, contributing to a more environmentally friendly vehicle operation.

  • 3-5. Materials and Construction

  • The construction of the OM 654 engine employs advanced materials, notably the all-aluminum design. This choice of materials not only contributes to the engine's lightweight characteristics but also enhances thermal efficiency and overall performance, showcasing Mercedes-Benz's commitment to innovative engineering in their diesel technology.

4. Performance and Compliance

  • 4-1. Emissions Legislation Compliance

  • Mercedes-Benz has designed the new diesel engine to comply with future emissions legislation, specifically addressing Real Driving Emissions (RDE). The company's commitment to these regulations emphasizes its focus on maintaining a balance between performance and environmental responsibility.

  • 4-2. Real Driving Emissions (RDE)

  • The report highlights that the RDE measures are actively supported by Mercedes-Benz. Unlike the current NEDC (New European Driving Cycle), the WLTP (Worldwide Harmonized Light Vehicles Test Procedure) cycle aims to align standard consumption figures with real-world conditions. This transition signifies an important evolution in testing and verification of vehicle emissions.

  • 4-3. Fuel Economy and Emissions Reduction

  • The OM 654 engine incorporates several features to enhance both fuel economy and emissions reduction. All relevant components for efficient emissions reduction are integrated directly on the engine, which eliminates the need for engine temperature management during cold starts or low loads. This configuration not only improves emissions performance but also leads to fuel savings, particularly on short drives. The use of multiway exhaust gas recirculation and advanced catalyst coatings further supports optimal operating conditions, showcasing Mercedes-Benz's innovative approach to diesel engine technology.

5. Market Strategies and Future Directions

  • 5-1. Shifts in Focus from EVs to ICE

  • Mercedes-Benz has acknowledged that its previous goals for electric vehicle (EV) adoption were overly ambitious. As a result, the company is now reallocating significant resources towards enhancing its combustion engine technology. This strategic pivot indicates a recognition of the ongoing relevance of internal combustion engine (ICE) technology, which CEO Ola Kallenius has stated will remain in use well into the 2030s.

  • 5-2. Investment in Combustion Engine Technology

  • Mercedes-Benz is making substantial investments in high-tech internal combustion engine technology. This move aligns with the company's commitment to comply with increasingly stringent emissions regulations while also balancing the development of new technologies, including electric vehicles (EVs) and advancements in digitization. The investment is part of a broader strategy to innovate within traditional gasoline and diesel powertrains.
