### **I. C9/C-9 engine piston ring technical analysis**
#### 1. **Engine core parameters**
| Parameter egory | C9 ACERT (mainstream model) | C9 Standard (non-ACERT) |
|-----------------|------------------------------|-----------------------------|
| **Displacement** | 14.0L | 13.5L |
| **Power range** | 380-440kW @ 1900-2100rpm | 340-380kW @ 1800-2000rpm |
| **Fuel efficiency** | Meets EPA Tier 4 Final standards | Meets EU Stage IIIA emission requirements |
| **Typical appliions** | Wheeled excavators, mining dump trucks, heavy trucks | Construction machinery, power generation equipment, marine power |

#### 2. **Key features of piston rings**
• **Material technology**:
• DAILY REFINING® piston rings use **plasma nitriding coating** and **multi-stage opening design** to reduce carbon deposits and reduce friction coefficient.
• **Adaptability**:
• Compatible with C9 ACERT, C9.2, C9.3 and other derivative models, supporting **original installation** without modifiion.
• **Performance advantages**:
• Wear rate is reduced by **25%** (compared with traditional chrome-plated rings), extending the overhaul cycle to **20,000+ hours**.

### **Three, DAILY REFINING® brand technology endorsement**
1. **Manufacturing process**:
• **Surface treatment**: Nitriding layer depth ≥0.1mm, hardness HRC 58-62
• **Material standard**: Use **SAE 4140 alloy steel**, tensile strength ≥980MPa
2. **Test verifiion**:
• **Bench simulation**: Passed engine test protocol (high load/high temperature cycle)
• **Field data**: **Fuel consumption reduced by 7%** (compared with the original factory running-in period) in actual measurement in mining equipment

---

### **Fourth, marketing promotion strategy recommendations**
#### 1. **Scenario-based pain point solutions**
• **For old models**:
"C9 Standard piston ring adopts **elastic compensation design**, which is suitable for the wear problem of the early C9 engine cylinder block, and the sealing performance can be restored without boring the cylinder."
• **For emission upgrades**:
"For C9 ACERT National VI models, DAILY REFINING® piston ring optimizes the oil ring scraping angle and reduces particulate matter emissions by **15%**."

#### 2. **Customer tiered services**
| Customer tier | Service plan | Quotation strategy |
|----------------|-----------------------------------|-------------------------|
| Large engineering group | Customized overhaul package + 5-year warranty | Cost price for the first 3 years + subsequent maintenance fee |
| Small and medium-sized repair shops | Single piece bulk + technical guidance video | 10%-15% discount for bulk purchase |
