Start of an internal combustion engine with at least one engine valve in an open state during cranking

A method of starting an internal combustion engine, comprising the steps of:

• maintaining one or more engine valves in an engine cylinder in a continuously open state for more than one engine cycle during engine cranking;
• determining whether an engine pressure parameter has reached a predetermined value;
• discontinuing maintaining the one or more engine valves in the continuously open state when it is determined that the engine pressure parameter has reached the predetermined value;
• and
• providing fuel to the engine cylinder for engine start-up subsequent to the discontinuation of maintaining the one or more engine valves in the continuously open state.

A method of starting an internal combustion engine, comprising the steps of:

• maintaining one or more engine valves in an engine cylinder in a continuously open state for more than one engine cycle during, engine cranking;
• determining whether an engine electrical parameter has reached a predetermined value;
• discontinuing maintaining the one or more engine valves in the continuously open state when it is determined that the engine electrical parameter has reached the predetermined value;
• and
• providing fuel to the engine cylinder for engine start-up subsequent to the discontinuation of maintaining the one or more engine valves in the continuously open state.

A method of starting an internal combustion engine, comprising the steps of:

• maintaining one or more engine valves in an engine cylinder in a continuously open state for more than one engine cycle during engine cranking;
• determining whether transmission oil pressure has reached a predetermined value;
• discontinuing maintaining the one or more engine valves in the continuously open state when it is determined that the transmission oil pressure has reached the predetermined value;
• and
• providing fuel to the engine cylinder for engine start-up subsequent to the discontinuation of maintaining the one or more engine valves in the continuously open state.
