WHAT’S SO GOOD ABOUT DIESEL?

Diesel fuel versus Petrol
Diesel fuel contains more carbon and hydrogen atoms than petrol does, (a petrol hydrocarbon molecule is typically C9H20, while a diesel molecule is typically C14H30). The carbon and hydrogen atoms when combined with oxygen are what produce the energy required to operate an engine. So... more carbon and hydrogen atoms in each molecule mean more energy. Diesel fuel contains nearly 20% more energy than petrol. This explains why diesel engines get better mileage than equivalent petrol engines.

Common Rail
Common rail technology produces higher pressure and better fuel atomisation than older diesel injection systems and lower engine noise and less emissions.



With the advent of Common Rail Technology and electronic control, diesel engines are rivalling petrol engines for power, and have significantly more torque.

Common rail engines pressurise the fuel to about 1,800 bar or 1,800 times atmospheric pressure. 1,800 bar injection pressure is equivalent to the water pressure of a depth of 18,000 meters – deeper than the Mariana Trench, the world’s deepest ocean bottom. High response electronic controlled injectors feature highly accurate multiple injections.

As a result, soot and pollutants are markedly reduced, while improvements in fuel efficiency and torque are also achieved. Engine noise and vibration is also reduced.

Diesel engines have the advantages of good fuel efficiency and low CO2 emissions. Diesel engine management systems have now been developed to further clean up emissions while improving fuel efficiency

These systems are products of various forms of advanced technology and have made modern diesel engines cleaner and more fuel efficient than petrol engines, but at the same time equalling or exceeding petrol engines in performance.
