Which of the following is a petroleum product used to drive high vehicles?

Options

A. Petroleum gas
B. Diesel
C. Kerosene
D. None of these

Answer

To determine which petroleum product is used to drive heavy vehicles, we can analyze the characteristics of different types of engines and fuels.

### Step-by-Step Solution:

1. **Understand the Types of Engines**:
- There are primarily two types of internal combustion engines used in vehicles: diesel engines and petrol (gasoline) engines.

2. **Identify the Characteristics of Diesel Engines**:
- Diesel engines have a higher compression ratio compared to petrol engines. This means that they can compress the air-fuel mixture more, which leads to more efficient combustion.
- Diesel engines are designed to produce more torque at lower speeds, making them suitable for heavy load-carrying vehicles.

3. **Identify the Characteristics of Petrol Engines**:
- Petrol engines typically operate at higher speeds and are used in lighter vehicles. They produce less torque compared to diesel engines at low speeds.

4. **Determine the Suitable Fuel for Heavy Vehicles**:
- Given that diesel engines are used in heavy vehicles due to their ability to produce the required torque for carrying heavy loads at low speeds, the fuel used in these engines is diesel.

5. **Conclusion**:
- Therefore, the petroleum product used to drive heavy vehicles is **diesel**.

### Final Answer:
The correct answer is **diesel**.
