Application Scenarios

Urban Construction: PC200-6/ZX200-3G engines power compact excavators for pipeline installation and road maintenance. Case Study: 320D engine enabled 24/7 operation in Shanghai metro project.

Mining Operations: 525HP QSX15 assemblies drive 100-ton mining dozers in coal extraction. Featured: D13F engines withstand -30°C to 50°C temperature extremes.

Forestry Applications: EC480D engines with enhanced cooling systems operate in high-dust environments.

Maintenance Tips

1. Replace oil filters every 500 hours for engines operating in high-dust conditions

2. Check coolant pH monthly – maintain between 8.3-10.5 for aluminum components

3. Use SAE 10W-30 oil for temperatures below -15°C

Troubleshooting Guide

1. Engine stalling: Check fuel injector pressure (1800-2000 psi required)

2. Overheating: Clean radiator fins – 40% efficiency loss from dust buildup

3. Hard starting: Test glow plugs – resistance should be 0.1-0.4 ohms
