Diesel engines are generally more fuel-efficient than petrol engines, offering better mileage due to higher energy density in diesel fuel. They provide more torque, making them ideal for heavy-duty vehicles and long-distance driving. Additionally, diesels tend to be more durable and have a longer lifespan, which can be cost-effective in the long run.
FAQs & Answers
- Why do diesel engines offer better mileage than petrol engines? Diesel engines provide better mileage because diesel fuel contains higher energy density, allowing them to extract more energy per unit of fuel compared to petrol engines.
- Are diesel engines more durable than petrol engines? Yes, diesel engines are usually built sturdier to handle higher compression, making them more durable and longer-lasting than petrol engines.
- What makes diesel engines better for heavy-duty vehicles? Diesel engines produce more torque at lower RPMs, which is ideal for heavy-duty vehicles requiring greater pulling power and endurance.
