Technical Overview of Mitsubishi S4S Engine Assembly
The Mitsubishi S4S engine assembly exemplifies cutting-edge engineering, combining advanced performance, fuel efficiency, and environmental compliance. Designed for durability and adaptability, this powerplant integrates Mitsubishi’s proprietary technologies to deliver a refined driving experience across diverse applications.
**1. MIVEC (Mitsubishi Innovative Valve timing & lift Electronic Control System)
The S4S engine employs Mitsubishi’s MIVEC technology, a dual-stage variable valve timing and lift system. By dynamically adjusting intake and exhaust valve timing and lift profiles, MIVEC optimizes combustion efficiency across all RPM ranges. At low-to-mid RPM, valve timing prioritizes torque output and fuel economy, while high-RPM operation shifts to a high-lift cam profile for enhanced power delivery. This dual-mode functionality ensures seamless transitions between efficiency and performance, achieving a balance of 157 PS maximum output and class-leading fuel efficiency (up to 15.4 km/L in combined cycles)
**2. Lightweight, High-Strength Construction
Constructed with a die-cast aluminum alloy block and cylinder head, the S4S engine achieves significant weight reduction without compromising structural integrity. Advanced friction-reduction measures—including low-viscosity 0W-20 oil compatibility, micro-polished valve stems, and a silent timing chain—minimize mechanical losses and noise. The compact design reduces engine length by 37 mm compared to conventional layouts, enhancing vehicle packaging flexibility
**3. INVECS-III CVT with SPORTS-MODE
Paired with Mitsubishi’s INVECS-III (Intelligent & Innovative Vehicle Electronic Control System) continuously variable transmission, the S4S engine delivers smooth power delivery and optimized fuel economy. The CVT’s adaptive logic learns driver behavior and adjusts gear ratios in real time, maintaining engine RPM within the most efficient range. The SPORTS-MODE 6-speed manual override provides dynamic control, enabling rapid acceleration and precise throttle response. Reinforced steel belts and a multi-layered pulley system ensure durability under high torque loads (up to 30 kg·m)
**4. Emission Control and Thermal Management
The S4S engine complies with stringent global emission standards through a combination of ultra-lean combustion and integrated exhaust gas recirculation (EGR). The redesigned cylinder head optimizes airflow dynamics, while a high-precision direct-injection system ensures homogeneous air-fuel mixture distribution. A dual-stage cooling system with an electronically controlled thermostat regulates operating temperatures, reducing warm-up times and minimizing thermal stress
**5. Modular Design and Compatibility
Engineered for versatility, the S4S platform supports hybridization and alternative fuels, including compatibility with e-fuels and hydrogen blends. Its modular architecture allows seamless integration with Mitsubishi’s PHEV and HEV systems, future-proofing the design for evolving environmental regulations
Applications
Ideal for mid-size sedans, crossovers, and light commercial vehicles, the S4S engine assembly is a benchmark in Mitsubishi’s powertrain portfolio, offering a harmonious blend of performance, efficiency, and sustainability. Certified by global energy agencies for its low CO₂ emissions and awarded the Eco Mark seal, it stands as a testament to Mitsubishi’s commitment to innovation and ecological responsibility
