Simko, A O; Harrington, J A; Havstad, P H

A method of operating an internal combustion engine of the spark ignition type with a fuel having a high latent heat of vaporization such as methanol by injecting the fuel in two stages, the first major portion of the fuel being injected at the start of the intake stroke into a bowl-in-piston cavity combustion chamber to be vaporized and atomized, the second smaller portion being injected late in the compression stroke just prior to ignition to remain close to the injector tip to richen the mixture adjacent the spark plug, and igniting the mixture.
