Leak testing apparatus

An apparatus, comprising:

• an actuation mechanism which comprises a plurality of actuators, wherein each actuator of the plurality of actuators is configured to seal a corresponding valve of a plurality of valves of a plurality of combustion chambers of an engine;
• a plurality of flow control devices configured to control a flow of a pressurized fluid to each combustion chamber of the plurality of combustion chambers;
• a plurality of sensors which comprise a first set of sensors and a second set of sensors, wherein,
• each sensor of the first set of sensors is disposed in a corresponding inlet channel of an inlet manifold to detect a first flow rate of the pressurized fluid in the inlet manifold, and
• each sensor of the second set of sensors is disposed in a corresponding exhaust channel of an exhaust manifold to detect a second flow rate of the pressurized fluid in the exhaust manifold;
• and
• a notification device configured to generate an alert based on the detected first flow rate and the detected second flow rate.

A method, comprising:

• in an apparatus:
• controlling an actuation mechanism to activate an actuator of the actuation mechanism and seal a valve of a combustion chamber of an engine based on the activation of the actuator;
• controlling a flow control device to control a flow of a pressurized fluid to the combustion chamber;
• controlling a plurality of sensors which comprise a first sensor and a second sensor, wherein,
• the first sensor is disposed in an inlet port of the combustion chamber to detect a first flow rate of the pressurized fluid in the inlet port, and
• the second sensor is disposed in an exhaust port of the combustion chamber to detect a second flow rate of the pressurized fluid in the exhaust port;
• determining a leakage of the pressurized fluid from the combustion chamber based on the detected first flow rate and the detected second flow rate;
• and
• controlling a notification device to generate an alert based on the determined leakage of the pressurized fluid from the combustion chamber.
