As of April 1, 2016, China’s non-road machinery sector has fully transitioned to the National III (Tier 3) emission standards. Mitsubishi Heavy Industries (MHI), a globally recognized leader in non-road engine manufacturing, took a proactive approach by introducing its mechanical Tier 3-compliant engines tailored for forklifts to the Chinese market as early as 2008. These engines have since gained widespread adoption among top-tier domestic forklift manufacturers. Furthermore, MHI’s EPA Tier 4-certified forklift engines (EPAT4) are already being mass-delivered to the North American market.
What sets Mitsubishi apart from conventional engine suppliers is its dual role as both a forklift manufacturer and an engine producer. This unique positioning ensures that its engines are meticulously engineered for forklift-specific applications. Key benefits include:
Forklift-Optimized Performance: Precision-designed to meet the rigorous operational demands of forklifts.
Advanced Swirl Combustion Technology: Ensures exceptional cold-start capability, minimized vibration, and quieter operation.
Long-Stroke Engine Architecture: Enhances low-speed torque output, making it ideal for forklift load-handling tasks.
To cater to the diverse needs of the Chinese market, MHI leverages its robust R&D expertise to offer the SQ and SS series of mechanical Tier 3 engines, supporting forklifts ranging from 1.5 to 7 tons. Notable models include:
The S4S Engine (2.5–3.5-ton capacity): With over 300,000 units sold, its long-term reliability is well proven.
The S4S(T) Engine (4.5–7-ton capacity): Features advanced 4-cylinder technology for superior smoothness and extended service life.
Heavy-Duty Solutions (8+ tons): MHI employs cutting-edge electronically controlled high-pressure common rail systems to achieve Tier 3 compliance.
Committed to sustainability, Mitsubishi Heavy Industries continues to prioritize energy efficiency and emissions reduction. Upholding its customer-centric philosophy, MHI remains dedicated to developing eco-conscious technologies, driving progress toward a greener future.
