Cold startability is one problem common to methanol vehicles because of methanol's low volatility. This study describes two necessary conditions for cold starting at -30 Cel: installing a cold start injector in the intake manifold and raising the Reid Vapor Pressure to 75.5 kPa. The cold start injector atomizes fuel to a 90 microms average diameter in the intake ports and improves the mixture distribution at a temperature as cold as -30 Cel. Moreover, accomplishing cold starting requires that the indicated mean effective pressure of 686 kPa and above must be sustained until fast idling is reached.
