Engine idling reduction system

A method for controlling an engine system having an engine and a voltage source, comprising:

• starting the engine system;
• activating an engine idling reduction mode allowing automatic shutdown of the engine;
• obtaining a discharge or charging current of the voltage source;
• obtaining a time since the voltage source was previously in a fully charged state;
• calculating a total energy consumption amount as a product of the obtained discharge or charging current and the obtained time since the voltage source was previously in the fully charged state;
• automatically shutting down the engine if the total energy consumption amount of the voltage source is less than a predetermined energy consumption amount;
• and
• triggering an automatic restarting of the engine, if the engine is automatically shutdown, based on at least two separate temperature measurements of engine temperature, the at least two separate temperature measurements being obtained at two separate respective locations in the engine.

A method for controlling an engine system having an engine and at least one voltage source, comprising:

• starting the engine system;
• activating an engine idling reduction mode allowing automatic shutdown and automatic restarting of the engine;
• and
• triggering an automatic restarting of the engine, if the engine is automatically shutdown, based on at least two separate temperature measurements of engine temperature, the at least two separate temperature measurements being obtained at two separate respective locations in the engine.

A method for controlling an engine system having an engine and at least one voltage source, comprising:

• determining if a temperature condition for disallowing automatic shutdown is satisfied, the temperature condition including at least one of ambient temperature being less than a predetermined ambient temperature value and charge air cooling temperature being less than a predetermined charge air cooling temperature value;
• setting a flag to one of ON if the temperature condition is satisfied, or OFF if the temperature condition is not satisfied;
• starting the engine system;
• activating an engine idling reduction mode allowing automatic shutdown of the engine;
• and
• disallowing automatic shutdown of the engine within the engine idling reduction mode if the flag is set to ON.
