High Fuel Economy: Diesel engines use a higher compression ratio instead of spark plugs, extracting more energy per liter than petrol engines.
Superior Torque: They deliver robust low-end pulling power at lower speeds, which reduces the need for frequent downshifting during heavy loads or steep climbs.
Long Range: Greater efficiency translates to significantly longer driving distances between refuelings, ideal for long-distance travel.
Challenges and Maintenance
Emissions Systems: Modern diesel engines require complex aftertreatment technologies like Diesel Particulate Filters (DPF) and Diesel Exhaust Fluid (DEF/AdBlue) to reduce harmful tailpipe emissions.
Driving Habits: Short, stop-and-go city commutes prevent the engine from reaching the high temperatures necessary for system maintenance.
