How Diesel Works

For some reason all over the world people believe that diesel needs to cost more than gas.  That is unreasonable the fuel diesel is made from crude oil, the sane as gasoline, the difference, however, is the refinement process.  Both diesel and gas go through similar refinement processes but diesel is less refined than gasoline so it costs less to produce than gas does, therefore the end product should cost less but for some reason the big oil companies don't think so.  I also mentioned earlier that diesel burns cleaner than gasoline.  That is because of the way it burns.  Inside the cylinder the fuel is compressed when the piston is pushed up in the cylinder when it reaches a certain pressure mixed with oxygen the two fuel become unstable and react with each other creating combustion. Gasoline engines burn a similar way only they need a spark plug to create ignition thus not burning as much fuel.  That is where people get the idea that gas is cleaner because it burns less fuel but that is not the case, that excess fuel not burned is put into the air out the exhaust.  With the diesel not using spark plugs the fuels are combusted at the optimal pressure causing a burn of most of the fuel in the cylinder meaning only fumes are released which are cleaner than releasing un-burned fuel into the atmosphere.  Since the fuel is burned at a high pressure it creates a more powerful explosion pushing the piston down harder creating more power, this is why vehicles that require the use of more power they use diesel engines in them.  Any diesel that is on the road now has a turbo on it a turbo works on the same principals of a supercharger which are to force more air into the air intake to create more power.  The difference, however, is a supercharger is belt driven and  a turbo charger is driven by exhaust turning a shaft that sucks air in through the intake. That is why when people need power to haul things they go with diesel.
