Daniels, C

This patent describes an ignition system for spark-ignited internal combustion engines operating with diesel fuel at a compression ratio in the range of about 17.5:1 to 21:1, the internal combustion engines having spark igniting means for the combustion chamber of each cylinder. It comprises an intake manifold, an exhaust manifold extending at least in part through the intake manifold, the exhaust manifold being heated, in normal operation of the engine, to a diesel fuel vaporizing temperature, and at least one fuel injector for injecting diesel fuel into the combustion chamber of each engine cylinder, the fuel injector being positioned to direct the fuel upon a portion of the part of the exhaust manifold that extends through the intake manifold, whereby the exhaust manifold heat vaporizes the diesel fuel before it enters the combustion chamber.
