Engine testing device which simulates dynamic gas exchange

An engine testing device comprising:

• a. an internal combustion engine including:
• (1) at least one engine cylinder, and
• (2) an air intake port through which air is admitted into the engine cylinder for combustion;
• b. a processor generating virtual valve output which is representative of the gas intake of at least one virtual cylinder of the internal combustion engine, wherein each virtual cylinder:
• (1) is not physically present in the internal combustion engine, and
• (2) simulates the performance of an actual cylinder present in the internal combustion engine and operating in conjunction with the engine cylinder;
• c. a passage communicating air from an air source to the air intake port;
• d. one or more valves in the passage, the valves being actuated in response to the virtual valve output.

An engine testing device comprising:

• a. an air intake adapter including:
• (1) passage walls which define a passage extending between:
• i. an air source and
• ii. an engine mount whereupon internal combustion engine intake port components may be situated,
• whereby the passage conveys air from the air source to any internal combustion engine intake port components situated on the mount;
• (2) valves provided along the passage walls, the valves being situated between:
• i. the passage, and
• ii. a pressure source having a different pressure than the air source,
• wherein the actuation of one or more of the valves exposes the passage to the pressure source;
• b. a processor generating virtual valve output which is representative of the gas intake of at least one cylinder of an internal combustion engine;
• wherein the valves of the air intake adapter are actuated in response to the virtual valve output.
