# Industrial Specification: Diesel Engine

## 1. Technical Definition
An internal combustion engine that uses diesel fuel compression ignition to convert chemical energy into mechanical energy.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **Compression pressure: 15-25 MPa, Peak cylinder temperature: 1800-2200°C, Injection pressure: 100-250 MPa**. Failure boundary: **Compression pressure exceeding 30 MPa causes piston ring failure, cylinder temperature exceeding 2400°C causes piston melting, injection pressure exceeding 300 MPa causes injector nozzle erosion**, Mechanism: **Thermal fatigue from cyclic heating/cooling (ΔT &gt; 500°C), cavitation erosion in fuel injection system (bubble collapse pressure &gt; 1 GPa), creep deformation at sustained temperatures &gt; 400°C**.

### 2.1 Analytical Physics Model
Governed by the **Heat Sterilization F0 Lethality Model**:

> **Primary Equation**: $F_0 = \int_{0}^{t} 10^{(T-121.1)/z} dt$  
> **Engineering Impact**: Validates microbial reduction integrity for aseptic packaging.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| T | Process Temp (°C) | **$T \in [1800-2200°C]$ °C** (Per `temperature_range`) |
| t | Exposure Time (min) | Engineering Constant |
| z | Z-value | **10 °C** (Standard for *C. botulinum*) |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Fuel injector nozzle coking from incomplete combustion deposits | 8 | Reduced fuel atomization causing uneven combustion and power loss | Multi-hole piezoelectric injectors with 2000 bar injection pressure and 0.1 ms response time |
| Cylinder liner cavitation from coolant pressure fluctuations | 8 | Pitting corrosion leading to coolant leakage into combustion chamber | Stiffened liner design with controlled coolant flow velocity &lt; 2 m/s and pressure stabilization chambers |
