25 views

The key difference between gas and diesel lies in their combustion process. Diesel engines ignite fuel through compression without spark plugs, offering better fuel efficiency and torque. Gas engines generally provide smoother, quieter operation and are more suited for lighter vehicles.

FAQs & Answers

  1. Which engine type is more fuel-efficient, gas or diesel? Diesel engines are generally more fuel-efficient due to their combustion process that relies on compression ignition.
  2. Why do diesel engines have more torque than gas engines? Diesel engines produce higher torque because they operate with higher compression ratios, providing more power at lower RPMs.
  3. Are gas engines quieter than diesel engines? Yes, gas engines typically provide smoother and quieter operation compared to diesel engines.
  4. Which engine type is better for lighter vehicles? Gas engines are generally more suited for lighter vehicles due to their smoother performance and quieter operation.
