SYSTEMS AND METHODS OF REDUCING A LOAD ON AN ENGINE
First Claim
1. A system for reducing an alternator'"'"'s load on an engine when the engine drives a second load, the system comprising:
- an alternator including a stator, a voltage regulator, a rectifier, and a field coil;
a battery having a first terminal and a second terminal both of which are coupled to the alternator;
a resistor having a first lead coupled to the first terminal and a second lead coupled to the field coil; and
a switch coupled in parallel across the resistor, the switch being open when the engine drives the second load and closed when the engine is not driving the second load.

Abstract
A system for reducing an alternator'"'"'s load on an engine when the engine drives a second load. The system includes an alternator, a battery, a resistor, and a switch. The alternator includes a stator, a voltage regulator, a rectifier, and a field coil. The battery has a first terminal coupled to the alternator and a second terminal coupled to the alternator. The resistor has a first lead coupled to the first terminal and a second lead coupled to the field coil. The switch is coupled in parallel across the resistor, and is open when the engine drives the second load and closed when the engine is not driving the second load.

7. A truck, comprising:
-
a cab; an engine; an air conditioner driven by the engine and configured to cool the cab; an alternator driven by the engine and coupled to the air conditioner, the alternator receiving a signal from the air conditioner indicating whether the air conditioner is operating or not operating, the alternator applying a first load on the engine when the air conditioner is not operating and applying a second load on the engine when the air conditioner is operating, the second load being less than the first load; and a battery charged by the alternator. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method of reducing a load on an engine, the method comprising:
-
driving an alternator by the engine, the alternator applying a first load on the engine; connecting a second load to the engine; providing a signal by the second load in response to the second load connecting with the engine; receiving the signal by the alternator; and reducing the first load on the engine when the alternator receives the signal. - View Dependent Claims (15, 16, 17, 18, 19)
