Related Questions
What is the difference between diesel and gasoline engines?
Diesel engines use compression ignition and higher compression ratios, delivering more torque and better fuel economy but producing more noise. Gasoline engines use spark ignition and are typically lighter, quieter, and rev higher than diesel engines.
Why are diesel engines preferred for commercial vehicles?
Diesel engines provide superior torque, better fuel efficiency, and greater durability under heavy loading. These characteristics make them more economical for commercial operations that involve hauling cargo or extended driving.
How do emission control systems work in diesel engines?
Modern diesel engines use selective catalytic reduction (SCR), diesel particulate filters (DPF), and exhaust gas recirculation (EGR) to reduce nitrogen oxides and particulate matter, meeting strict environmental standards.
