Since hydrocarbons, carbon monoxide, and other matter

Since the beginning of the industrial era, humans have been relying more and more on fuels like oil and coal and will probably continue relying on them until they run out. The persistent increase in oil prices over the past decade suggests that global oil markets have entered a period of increased scarcity. We globally use 11 billion tons of oil every year and if our population remains the same, this world’s oil deposit can only last until 2052.

If we keep on using fuels, it will slowly run out.    The burning of fossil fuels by humans is the largest source of emission of CO2 .   Today, scientists are trying to find alternative fuels that can act as a substitute for natural fuels that are running out. Biodiesel is one of the ways.   Biodiesel (mono-alkyl esters) is a “cleaner” burning diesel fuel made from natural and renewable sources like vegetable oils. Biodiesel operates in combustion-ignition engines, just like petroleum diesel.   This means that no engine modifications are required, and biodiesel maintains the capacity and range of diesel.

 The use of biodiesel in a conventional diesel engine results in a large reduction of unburned hydrocarbons, carbon monoxide, and other matter harmful to the environment.  Emissions of nitrogen oxides are either slightly reduced or slightly increased. It is depending on the engine. The use of biodiesel decreases the solid carbon fraction of particulate matter because the oxygen in biodiesel enables complete combustion of CO2 and eliminates the sulfate fraction. This results in the hydrocarbon staying the same or increasing. This means that biodiesel works well with new technologies and catalysts. It reduces the soluble fraction of diesel particulate but not the solid carbon fraction, particulate traps, and exhaust gas recirculation leading to longer engine life.
