Abstract
In some embodiments, there is provided a method of controlling a pressure gradient between a combustion chamber and a crankcase of an engine, the method having: receiving, at a control device, a signal indicating that a lubricant container is coupled to a lubricant circulation system associated with the engine, in response to the received signal, providing data to cause operation of a suction control device for facilitating control of the pressure gradient.
Claims47
A method of controlling a pressure gradient between a combustion chamber and a crankcase of an engine, the method comprising:
- receiving, at a control device, a signal indicating that a lubricant container is coupled to a lubricant circulation system associated with the engine;
- and
- in response to the received signal, providing data to cause operation of a suction control device for facilitating control of the pressure gradient such that a pressure in the crankcase is maintained lower than a pressure in the combustion chamber.
A method of inhibiting or reducing entry of a lubricant from a crankcase in to a combustion chamber of an internal combustion engine, the method comprising:
- maintaining a pressure gradient between the combustion chamber and the crankcase using a suction control device such that a pressure in the crankcase is maintained lower than a pressure in the combustion chamber.
An apparatus configured to control a pressure gradient between a combustion chamber and a crankcase of an engine, comprising:
- a control device configured to receive a signal indicating that a lubricant container is coupled to a lubricant circulation system associated with the engine,
- wherein the apparatus is further configured to, in response to the received signal, provide data to cause operation of a suction control device for facilitating control of the pressure gradient such that a pressure in the crankcase is maintained lower than a pressure in the combustion chamber.
