The report describes an investigation carried out to determine the extra amount of fuel used when a car is started from cold, and so refines the estimates of fuel consumption made in earlier work. A car and a minibus were driven round the small loop of the RRL track. On each run, a start from cold was made, and laps were continued until a steady consumption was attained. The relationships between the extra fuel used and air temperature and method of driving were investigated. The main conclusion is that the extra fuel used in starting from cold would be sufficient to allow the car to travel an additional 1 1/2 to 2 1/2 kilometres; this distance increases with decrease in air temperature and increases with increase in average speed. Average over all trips, the formulae measured when the engine was fully warm were found to underestimate the amount of fuel used by about 10 per cent. (Author)
