ABSTRACT:
An engine combustion system is provided wherein fuel is supplied to the engine combustion chamber in the form of a hot vapor. The system preferably includes a preburner wherein a portion of a liquid fuel supply is burned internally to provide a hot, gaseous admixture of gasified fuel and products of combustion. A portion of the output of the preburner is used to heat air induced into the intake manifold, the heated air being thence supplied to the combustion chamber. The output of the preburner can also be used in auxiliary units such as a heating system for the passenger compartment. For a piston-type engine, the gaseous fuel is released into the combustion chamber formed by the clearance volume above the piston at the top center position of the piston, air being compressed within a recess in the cylinder during the cylinder head and rushing past the fuel inlet upon the downstroke of the piston to provide thorough mixing and, hence, complete burning of the gaseous fuel. The system described also includes temperature and pressure controls for both normal operation and startup as well as hydraulic controls for the fuel release valve assembly, the fuel release valve assembly including both an operator-controlled metering valve and an engine speed responsive poppet-type timing valve.
