diesel is in principle easier to refine than gasoline, it needs to be cleaned from more pollutants to ensure that tailpipe emissions remain as low as possible. However, diesel contains more energy than petrol and the vehicle’s engine combustion process is more efficient, adding up to higher fuel efficiency and lower CO2 emissions when using diesel
a diesel engine is more efficient than a spark-ignited petrol engine having the same power output when the engines are installed in a vehicle having a similar mass.his results in the diesel having lower fuel consumption - a common margin is roughly 40% more km travelled for an efficient turbo-diesel engine
diesel fuel is denser than petrol and contains about 15% more energy by volume
efficiency of the diesel engine is still some 20% greater than the petrol engine, despite the diesel engine also being heavier
1kg of diesel burnt under ideal conditions will produce 2.68kg of CO2. 1kg of petrol burnt under ideal conditions will produce 2.3kg of CO2
