THE LUCAS ENGINE

12 ADVANTAGES OF THE
LUCAS ENGINE
OVER PISTON ENGINES

1.	Completely expands the burnt air/fuel mixture during the Power Stroke. The piston engines exhaust the gases at 100 PSI thus wasting significant energy. See the Lucas Cycle comparison with the Otto Cycle.

2.	Will produce about 9 times* more** torque per revolution of the motor shaft than a comparable 4 cylinder 4 stroke engine.**

3.

Controls power by reducing or increasing the number of explosions per cycle, instead of varying the quantity of fuel in a fixed volume of air.

Leaner mixtures produce more NOx, gases responsible for smog & Acid Rain, which the Lucas Cycle avoids. Operates in near optimal combustion conditions (stoichiometric) through high and low power demands. This means more economy for the same power generated and less pollutants.

4. Produces high torque at lower speeds, thus allowing power to flow directly from the clutch to the differential mechanism.

Coupled with the capability to varying the number of explosions per cycle, it does away with the expensive gearbox.
In a 2x3 engine configuration, ratios will be 6 x 1, 3 x 1, 2 x 1, 1 x 1, very closely matching the ratios of a four-speed gearbox.

5. Idling Piston Engines, typical of stop-and-go traffic, waste a lot of fuel and its exhaust gases are responsible for most of the air pollution in large urban areas.

In the 34 OECD member states, the monetary impact of death and illness due to outdoor air pollution was $1.7 trillion in 2010. Research suggests that motorized on-road transport accounts for about 50 percent of that cost.

The Lucas Cycle only compresses air for the active Cylinder, and runs only to keep the Rotor moving. Thus, it needs only a minimum of explosions, even one every two, or ten revolutions.

For a quick calculation, say a 6 cyl piston engine revving up at 800 RPM produces 6x800/2=2400 explosions in one minute. A Lucas engine 2x3 configuration conservatively rotating at 60 RPM with only one explosion per cycle will generate 60 explosions in one minute, or 40 times less volume of gases.

In terms of pollution abatement, this is equivalent to removing 39 out of 40 idling cars on the road!

6. Since it only compresses air, and not the air/fuel mixture, the Lucas Cycle can use higher compression for lighter fuels like gasoline, because pre-ignition is eliminated by design.

There is no need to put expensive anti-knock additives in the gasoline. The result is higher efficiency, or more economy in the operation of the Lucas motor.

7.

Simple to build.

Only two cylinders and three cavities in the rotor do the work of a twelve cylinder Piston Engine (to produce six power strokes per revolution). Even when compared to the four cylinder engine that today powers most automobiles, the reduction in components of the Lucas engine is impressive.

This means LOWER PRODUCTION costs.

8.	Lower discharge temperatures and much lower production of NOx gases will greatly reduce the expense of components of a catalytic converter or even eliminate the need for one.

9. Variable Compression Ratio (VCR) is a much desired characteristic of internal combustion engines (see 2- above).

Some very expensive engines developed complicated mechanisms to accomplish this. The Lucas engine has this feature built into its design. Increasing the fuel in the air/fuel mixture produces more pressure in the combustion chamber, automatically increasing piston travel and air reservoir pressure. Decreasing the fuel content has the reverse effect. The neat result is bringing back a near ideal operation.

10.

Smooth Power Curve 

The Lucas Cycle torque is produced by tangential forces to the Rotor with multiple power events spread out per revolution.

With a piston engines the output torque is ZERO at Top Dead Center when the force at the top of the piston is near maximum. Torque is largest at about 90 degrees, when the lateral forces on the piston produce the highest friction on the cylinder walls.

Using a bicycle metaphor for a piston engine, it is like putting all your weight on a bike pedal at the 12 o’clock position - one does not go anywhere. At 3 o'clock one takes off.

The Lucas Cycle is always at the 3 o'clock position.

11. High Power to Weight ratio comes from lower size coupled with all the preceding advantages.

We estimate (at a minimum) an engine and power train weight reduction of 50%.

12.

Potential stealth application due to reduced exhaust heat signature and reduced exhaust sound.
