# Industrial Specification: Fuel Injection Pump

## 1. Technical Definition
A high-pressure pump that delivers precise amounts of fuel to the injectors in a diesel or direct injection gasoline engine.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **150-2000 bar**. Failure boundary: **Plunger-to-barrel clearance exceeds 3.5 μm or camshaft lobe wear exceeds 0.2 mm**, Mechanism: **Hydrodynamic lubrication breakdown in plunger-barrel interface due to fuel viscosity dropping below 1.8 cSt at 100°C, causing metal-to-metal contact and adhesive wear**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.
