Abstract
The internal combustion engine includes an engine preheating apparatus for preheating the internal combustion engine upon or before starting thereof. This internal combustion engine further includes an air-fuel ratio controller for setting an air-fuel ratio of the internal combustion engine that is preheated, to a value higher than that of the internal combustion engine that is not preheated, and/or an ignition-timing controller for retarding an ignition timing of the internal combustion engine that is preheated as compared with the ignition timing of the internal combustion engine that is not preheated.
Claims18
An internal combustion engine, comprising:
- an engine preheating apparatus which preheats the internal combustion engine upon or before starting thereof;
- and
- an air-fuel ratio controller which sets an air-fuel ratio of the internal combustion engine that is preheated by the engine preheating apparatus to a value higher than the air-fuel ratio of the internal combustion engine that is not preheated by the engine preheating apparatus.
An internal combustion engine, comprising:
- an engine preheating apparatus which preheats the internal combustion engine upon or before starting thereof;
- an air-fuel ratio controller which sets an air-fuel ratio of the internal combustion engine that is preheated by the engine preheating apparatus to a value higher than the air-fuel ratio of the internal combustion engine that is not preheated;
- and
- an ignition-timing controller which retards an ignition timing of the internal combustion engine that is preheated as compared with the ignition timing of the internal combustion engine that is not preheated.
A method for controlling an internal combustion engine, comprising the steps of:
- preheating the internal combustion engine upon or before starting thereof;
- and
- setting an air-fuel ratio of the internal combustion engine that is preheated to a value higher than the air-fuel ratio of the internal combustion engine that is not preheated.
