Government procurement case of Ford New Generation V348 service vehicle in Changchun: Bid-winning solution analysis and winter operation assurance. I. Case Background: Procurement Requirements under Northern Severe Cold Conditions. In December 2025, a municipal sanitation department in Changchun planned to procure a batch of mobile service vehicles for road inspection, equipment maintenance, and emergency response. Due to Changchun’s location in Northeast China—where winter temperatures frequently drop to -25°C to -35°C—the vehicles required exceptional cold-start capability, stable hydraulic systems, and freeze-resistant performance. Following an open tender, Chengli Special Purpose Vehicle Co., Ltd. stood out among multiple bidders with its Ford New Generation V348-based mobile service vehicle solution, ultimately delivering six units at approximately RMB 320,000 per unit (based on publicly available tender information). These vehicles primarily support daily inspection and emergency repair operations along urban trunk roads and key zones, requiring reliable engine start-up at -30°C and smooth, non-jamming operation of the hydraulic lifting platform (used for raising maintenance equipment) under low-temperature conditions. The client explicitly specified requirements: engine-mounted fuel heater; low-temperature, high-cranking-power battery; and hydraulic oil rated for -35°C operation. Chengli’s solution fully met these core requirements—key to its successful bid. II. Key Analysis of the Winning Solution: Configuration and Freeze-Resistant Design of the Ford New Generation V348 Service Vehicle. The Ford New Generation V348 chassis itself offers strong reliability; Chengli Special Purpose Vehicle further enhanced its winter operational capability through deep customization. 1. Low-Temperature Starting System: Standard equipment includes a fuel heater (German Webasto or equivalent), capable of preheating engine coolant down to -40°C to ensure one-button engine start. Additionally, a 12V/120Ah low-temperature, high-cranking-power battery (model: CLW5040XDYJ6, compliant with official announcement specifications) is installed, delivering up to 800 CCA cold-cranking amps—significantly exceeding the ~500 CCA typical of standard batteries. The engine employs an electronically controlled high-pressure common-rail system (meeting China VI emission standards), combined with glow plugs, enabling start-up within 3 seconds at -30°C. 2. Hydraulic System Freeze Protection: The service vehicle’s hydraulic lifting platform (maximum lift height: 1.8 m) uses low-temperature hydraulic oil (pour point ≤ -35°C); hydraulic lines are wrapped with thermal insulation material (10 mm thick, flame-retardant rating V0) and equipped with electric heating sleeves (300 W power, auto-activated temperature control). Field testing in Changchun’s winter confirmed stable lifting/lowering performance at -25°C, with no oil solidification or hose rupture observed. 3. Compartment Thermal Insulation and Freeze Protection: The compartment features integrated foam insulation (50 mm thick, thermal conductivity ≤ 0.03 W/(m·K)), interior-mounted fuel heater (optional), and electric defrosting system (for windshield and side mirrors). The water tank (20 L capacity, used for handwashing or equipment cleaning) is constructed from stainless steel and fitted with electric heating tape to prevent freezing during winter. III.
