Reducing consumption of fossil fuels and resulting emissions remains a goal of the worlds’ population. Perhaps as an aid to encourage more fuel-efficient driving style, many modern motor vehicles are equipped with digital displays of average and instantaneous display of fuel efficiency in miles per gallon (mileage) or liters per 100 kilometers. The display may be interesting to drivers concerned with fuel efficiency, but may not yield desired or best results. What is missing is impact on time of travel; what is the fuel- and time-efficient way to accelerate, what steady speed to travel, and how to decelerate? The author has defined a new fuel efficiency measure described as Dynamic Fuel Cost, in units of currency such as dollars, per travel time in hours, and a microprocessor to compute and display same. Using this display, vehicle operators can choose a maximum steady highway speed, accelerate and decelerate in ways that are fuel-, time- and cost-effective and minimize emissions.

Continual investigations into the area of alternative fuels are being conducted in an effort to reduce the emission of tomorrow's internal combustion engines. Recent efforts in both the automotive and heavy-duty industry have focused on the evaluation of methanol, ethanol, and reformulated gasoline liquid fuels in this vein. With this advent of light fuel usage in direct injection engines, the criticality of adequately performing fuel injection equipment is amplified. Typical, unassisted, direct injection fuel systems have their roots in diesel equipment. With rare exception, standard diesel injection equipment is not directly applicable to the utilization of light fuels. Via a program sponsored by the U.S. Environmental Protection Agency, a high speed, electronic, methanol compatible direct injection fuel system has been developed and demonstrated. The base pump design utilized for this effort was AMBAC's mechanical Model 100 diesel fuel injection pump.

The development of a Type F automatic transmission fluid requires care in selection of base stocks and additives in order to achieve the desired balance of performance properties. Considerations involved in selection of antiwear agents, detergents-dispersants and antioxidants are enumerated. Tests are described for use in evaluating the additives, and performance properties of fully formulated fluids are shown. The performance of non-Type F automatic transmission fluids in transmissions designed specifically for Type F fluids are described.
