Abstract:
1. A more fuel-efficient automotive vehicle comprising: (a) an internal combustion engine powered directly by gasoline, (b) a piston-type steam engine powered indirectly by gasoline, (c) with both said piston-type steam engine and said internal combustion engine connected to a drivetrain, (d) a self-contained gasoline-powered boiler to produce the necessary steam, (e) a condenser to recycle the spent steam from the piston-type steam engine, (f) said internal combustion engine and said boiler receive combustible fuel from the fuel tank, (g) said piston-type steam engine receives steam from the boiler, (h) said boiler generates steam by the direct combustion of gasoline within the boiler apparatus to heat water and thus generate steam, (i) said piston-type steam engine is capable of transmitting force directly to a drivetrain and thus powering the vehicle alone after a warm-up period without the concurrent operation of the internal combustion engine, (j) said internal combustion engine burns fuel and transmits power to a drivetrain to power the vehicle upon starting from cold, (k) wherein after adequate steam pressure has been attained in the directly gasoline-powered boiler apparatus, operation of the internal combustion engine ceases and the piston-type steam engine is able to power the vehicle alone independently for the remainder of the trip, (l) wherein the relatively superior power and thermal efficiency of the steam engine as compared to the internal combustion engine allows for augmented overall fuel efficiency and reduced emissions.
