Demand for gasoline has been the driving force in utilization and depletion of crude petroleum, which is a non-renewable resource. In recent years, tendencies have just begun to, at times, favor alternative fuels to power autos. Many possible alternative fuels exist, certainly not without their drawbacks. These alternatives include, but are not limited to, various batteries coupled with solar power, alcohols, gasohols, and both liquefied and gaseous natural gas, as well as hydrogen. As mentioned above, drawbacks do exist; the chief drawbacks being cost of adaption / implementation, engineering, and cost of the fuels themselves. As stated by many a chairman of petroleum companies, alternative fuels have limited applications and too many economic disadvantages, (Derr, 30).
These alternatives involve modified internal combustion engines, ICE's, modified fuel delivery systems, as well as advancements in the field of electrical storage capacities. This paper will attempt to discuss the many advancements in the field of automobile alternative fuels, reduced and zero emission vehicles, and fuel delivery and ICE modifications producing reduced emissions.

There have been many advancements in reducing emissions of gasoline and diesel powered vehicles. Every month we hear of another vehicle running on petroleum fuels, reducing emissions, and increasing efficiency. "Direct diesel injection into ICE cylinders increases mileage by 20%," (DiChristina, 43), for example. Also, ozone precursor release in the 1960's was on average 324 lb/Yr., whereas now it is 21 lb/Yr. In 1998 it is expected to be 12 lb/Yr., a 96% improvement (Derr, 30). But this paper is examining non-petrol fuels. There are also many advancements in the non-petroleum field, as well as advancements in engines burning gasoline in addition to other...
