Abstract
A gaseous fuel internal combustion engine including a crankcase; a pump configured to transport blow-by gas including the gaseous fuel contained within the crankcase therefrom to an outlet; and a controller configured to control the pump output based on one or more determined operating parameters of the engine.
Claims28
A gaseous fuel internal combustion engine comprising:
- a crankcase;
- a pump configured to transport blow-by gas including the gaseous fuel contained within the crankcase therefrom to an outlet;
- and
- a controller configured to control the pump output based on one or more determined operating parameters of the engine.

A method of controlling a flowrate of expelled gas transported from a crankcase of a gaseous fuel internal combustion engine, the expelled gas including the gaseous fuel, the engine comprising a pump arranged to transport the expelled gas from the crankcase to an outlet, the method comprising the steps of:
- determining one or more operating parameters of the engine;
- and
- controlling the pump output based on the one or more determined operating parameters.
-42. (canceled)
A gaseous fuel internal combustion engine, comprising:
- a crankcase;
- and
- a ventilation system comprising a gas pressure source and a ventilation path, the gas pressure source configured to transport blow-by gas, including the gaseous fuel, contained within the crankcase therefrom via the ventilation path as an expelled gas,
- wherein the ventilation system further comprises a monitoring system configured to monitor an actual parameter indicative of a flowrate of the expelled gas, and
- wherein the monitoring system is configured to provide one or more outputs based on the monitored actual parameter.
