Yuchai YC6J Series: High-Performance Power Solution for Sand and Aggregate Transportation - Cases

In order to objectively assess the actual performance of Yuchai YC6J180-33 and YC6J220-33 engines, field operation tests were carried out under real working conditions for sand and aggregate transportation.

The test runs between sand and gravel yards and material stockyards, covering mainly dirt roads and simple gravel roads. The one-way distance ranges from 50 to 80 km, with a round trip within 150 km. Such conditions are highly consistent with the daily operation scenarios of local transport users.
