CRC Hot Start and Run Technique Investigations (Report of Hot Start Technique Panel of Volatility Group of Motor Vehicle Fuel, Lubricant and Research Committee of Coordinated Research Council) 680435
A test technique has been developed that permits evaluation of passenger car hot start and run characteristics at various severity levels with a minimum of instrumentation. The most critical of several test conditions investigated in five cars at approximately 95 F ambient were a 20-mile warmup at 70 mph followed by a 20-minute engine-off soak period.A hot start and run is defined as an engine start followed by an idle period of at least one minute. The technique gives satisfactory results when using adjusted RVP for two stalls or for a 4 sec start. Two fuel series are desirable but one series, more severe than average commercial summer gasolines, should be satisfactory for survey purposes.
