Given that transportation consumes more than its fair share of energy resources, a lot of strategies are being implemented to lower its environmental impact and make it more affordable in the process. The approaches used include such things as alternative fuels, alternative motors, and altering the transportation infrastructure itself.
What’s in the Tank
In terms of vehicles themselves, changing the type of fuel used in them is the easiest way to make them environmentally friendly. This technique doesn’t rely on a major switch from internal combustion engines to electric, or some other type of motor.
Ethanol has already seen widespread use throughout the world. This fuel can be made from renewable crops and requires just a few modifications to existing engines.
According to a Festec engineering professional, for existing engines to handle ethyl alcohol with minimal damage, alternative gasket materials have to be used for piston rings, cylinder head seals, and other vulnerable spots. With biologically-generated methane, the alterations are more extensive and include pressurized tanks.
