Abstract
An engine testing device including a plurality of seal head units movable forward and backward relative to the intake ports and the exhaust ports. Each of the seal head units includes a plurality of seal heads disposed side by side and are connectable to respective ports of the intake ports and the exhaust ports. A pitch-varying unit changes interval pitches between the seal heads of at least one of the seal head units. The pitch-varying unit includes a plurality of first movement mechanisms connected with the seal heads and movable in a direction across the seal heads disposed side by side, and a plurality of drivers to drive the first movement mechanisms.

An engine testing device configured to test an engine with a plurality of ports including intake ports and exhaust ports in a pseudo driving state, the engine testing device comprising:
- a plurality of seal head units movable forward and backward relative to the intake ports and the exhaust ports of the engine, each of the seal head units including a plurality of seal heads disposed side by side and connectable to respective ports of the intake ports and the exhaust ports;
- at least one pitch-varying unit for at least one of the seal head units to change interval pitches between each adjacent pair of the seal heads of the seal head unit;
- and
- the at least one pitch-varying unit comprises:
- a plurality of first movement mechanisms respectively connected with the seal heads and movable in a direction in which the seal heads are disposed side by side;
- and
- a plurality of drivers to respectively drive the first movement mechanisms.
