Testing unit for testing a multi-cylinder engine

A testing unit configured to test a multi-cylinder engine including a plurality of ports including an intake port and an exhaust port in a pseudo driving state, comprising:

• a plurality of pressure inspection units;
• and
• at least one opening/closing mechanism,
• wherein each of said plurality of pressure inspection units includes:
• a pipeline connected to one of the plurality of ports;
• and
• a valve for opening/closing the pipeline,
• wherein the pipeline includes a mounting unit to which a sensor for detecting a pressure in the pipeline is mounted, the mounting unit being positioned between the valve and the intake port or the exhaust port;
• wherein said opening/closing mechanism includes:
• one actuator;
• and
• a transmission mechanism connected to the actuator and transmitting a driving force of the actuator to an operation unit of each of the plurality of valves to open and close the plurality of valves,
• wherein said transmission mechanism includes:
• a plurality of link members which is moved by the driving force, each link member including an engaging unit;
• and
• a plurality of handle members,
• wherein one end portion of each handle member is connected to a corresponding operation unit, and
• wherein the other end portion of each handle member is engaged with the corresponding engaging unit.
