THE ENGINE I AM INVESTIGATING IS THE HONDA GX160 AND
FOR MY PRESENTATION I WILL BE LOOKING AT HOW THE
FUEL USED IN THE ENGINE HAS BEEN DEVELOPED OVER THE
YEARS AND HOW IT WILL CHANGE IN THE FUTURE.
The FUEL
THE HONDA GX160 ENGINE USES PETROL WHICH IS A
PETROLEUM DERIVED LIQUID AND IS FOUND IN CRUDE OIL
OIL DRILLING
CRUDE OIL ITSELF IS EXTRACTED THROUGH OIL DRILLING.
GEOLOGISTS SELECT THE SUITABLE AREAS OF LAND THAT
CAN BE USED FOR OIL DRILLING AND AFTER THE LAND IS
CLEARED AND LEVELLED THE CREW WILL START TO DRILL A
HOLE. IF YOU LOOK At THE DIAGRAM YOU CAN SEE A
PUMPING SYSTEM WHERE THE ELECTRIC MOTOR IS
CONNECTED TO A SYSTEM WHICH MOVES A PUMP UP AND
DOWN IN THE HOLE CREATING A SUCTION WHICH DRAWS
THE OIL UP
FRACTIONAL
AFTER IT HAS BEEN EXTRACTED FROM THE GROUND IT HAS
TO BE REFINED. fractional distillation is used in oil refineries
to separate crude oil into useful substances having different
hydrocarbons of different boiling points. Heated crude oil is
inserted at the bottom where Lower chain hydrocarbons
vaporise and they rise up the column and condense and are
collected at their respective boiling point levels. In the
column as you go up the temperature the boiling point and
the length of the hydrocarbon decreases. So u can find petrol
near the top and fuel for ships near the bottom.
THE FUTURE
So we have talked about how fuel has been developed until
now so what does the future have in store for petrol In
recent times countries such as the UK France and China
have announced that they will ban the sales of petrol
and diesel cars in the next 20 years. So the internal
combustion engine is coming under increased scrutiny,
due to demands of increased efficiency and lower
emissions. These demands have led the way to the
decreased production petrol and diesel and rise in
electric motors. However internal combustion engines
are still used in many vehicles and the decline will be
very gradual so petrol as a fuel is safe in the near future
however it is likely that it will be replaced within the next
30 years.
