This paper describes a programme of statistical analyses on test data conducted to investigate the effects of a number of factors on car fuel consumption. The data used for the analyses were obtained from a comparative study of the fuel economy of pe

Classical methods of design and analysis of engine components are in danger of fragmentation and falling into disuse because of their ad hoc development and lack of continuity of personnel. It is argued that although advanced and comprehensive numeri

This paper presents a forecast of the expected shape, drag, power unit, transmission, weight etc. of the motor car in the year 2000 and beyond. Some consideration is given to whether a car in any form will be in existence at that date.

A new look is taken at the analytical procedure for reducing the results of the coast-down test. A three-degree-of-freedom model is discussed, and a derivative-based correction algorithm is shown to account for changes in ambient conditions. A parame

The alternative to the oil based fuels for transportation are considered. These are the synthetic fuels, made from coal, the liquid petroleum gases of propane and butane, compressed natural gas and methanol. The problems associated with the use of el

Emissions of nitric oxide and hydrocarbons are affected by various parameters, combustion duration interval being one of them that can alter the levels of nitric oxide in the exhaust. To some extent hydrocarbon emission depends upon the temperature p

The formation of nitric oxide in the combustion chamber of a spark ignition engine is formulated by developing a simple model. The state of the gas in the chamber and its thermal properties are estimated during a complete cycle. A simple heat transfe
