Abstract

A fuel-efficient automotive vehicle is provided having a power train including a primary internal combustion engine, an auxiliary engine, and a coupling system which selectively transfers power from the auxiliary engine to the primary engine when the speed of operation of the auxiliary engine equals the speed of the primary engine. The speeds of both engines are controlled by separate gas pedals conventionally located within the vehicle. The primary engine is of smaller power and better fuel efficiency than an engine which would generally be required by the vehicle. Although the primary engine can maintain the vehicle at a cruising speed, it relies upon the added power of the auxiliary engine for acceleration and hill-climbing.

Claims

1. An automotive vehicle having power train means comprising:

a) a primary internal combustion engine having sufficient power to maintain said vehicle at cruising speed and equipped with a crankshaft having front and rear ends,

b) an auxiliary internal combustion engine having an output shaft, and having a power sufficient, when combined with the power of said primary engine, to impart acceleration to said vehicle,

c) coupling means releasibly interactive between said output shaft and the front end of said crankshaft, and

d) speed change transmission means associated with the rear end of said crankshaft, whereby

e) power from said auxiliary engine may be selectively conveyed to said crankshaft to supply additional power for accelerating said vehicle, and

f) after the vehicle reaches cruising speed, the auxiliary engine may be disengaged from said crankshaft and throttled down or stopped altogether to conserve fuel, thereby

g) enabling said vehicle to travel at cruising speed with reduced fuel consumption on power provided by said primary engine alone, and

h) enabling said auxiliary engine to remain ready to be reactivated whenever increased power is needed, said vehicle being further equipped with a rechargeable storage battery interactive with said power train means, and separate gas pedals for the control of said primary and auxiliary engines.

2. The vehicle of claim 1 wherein said crankshaft is of high capacity construction designed to withstand the combined power from said primary and auxiliary engines.

3. The vehicle of claim 1 wherein the output shaft of said auxiliary engine and the crankshaft of said primary engine are in coaxial alignment.

4. The vehicle of claim 1 wherein said power train means contains an electric motor adapted to add power to said primary engine.

6. The vehicle of claim 1 wherein said rechargeable storage battery is a 12 volt lead/acid battery.

5. A process for modifying an existing automotive vehicle for the purpose of improving its fuel economy, said vehicle having an existing internal combustion engine equipped with multiple cylinders symmetrically positioned with respect to a center axis, and having a crankshaft extending between front and rear ends, said process comprising:

a) deactivating two or more of said cylinders while preserving the positional symmetry of the remaining cylinders, said deactivation including removal of moving components interactive with said cylinders,

b) adding an auxiliary internal combustion engine capable of variable operational speed independent of said existing engine, and having a rotating output shaft, and

c) providing coupling means interactive between said output shaft and the front end of said crankshaft for controllably adding the power of said auxiliary engine to the power of said existing engine when the rotational speed of said output shaft is caused to equal the rotational speed of said crankshaft.
