en urged to double the real price of petrol, triple the use of public transport, and halve the size of its current 19 billion roads program by 2005. The findings have raised interest in possible alternative fuels," (Cavenagh, 15).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. Positive and negative aspects to implementation will be discussed as well as an analysis made on whether the alternative approach is feasible on a mass production scale.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 2001 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 fuels such as alcohol, and various combustible gasses such as butane, propane, methane."Martin-Marietta Energy Systems Inc. of Oak Ridge, Tennessee, has developed a magnetohydrodynamic engine that converts the chemical energy of liquid or gaseous fuels into variable-frequency alternating-current electrical power. Nicholaos Pahis of Vernon, Connecticut, has developed a rotary internal combustion engine with an inherently balanced 8-cylinder design that ingests a constant air/fuel mixture.
