China Yuchai Introduces New High-Powered Marine Engine

SINGAPORE,March 10,2020 -- China Yuchai International Limited (NYSE: CYD) ("China Yuchai" or "the Company"),a leading automotive manufacturer and distributor of engines for on- and off-road applications in China through its main operating subsidiary,Guangxi Yuchai Machinery Company Limited ("GYMCL"),announced today that GYMCL has introduced an advanced high-powered marine engine to address the growing demand of the domestic marine industry,particularly vessels in the yacht class.

Stronger,lighter and more compact engines are typically required for the drivetrain in the yacht class of boats. The mainstream product market for Chinese boat engines is presently monopolized by imported brands.

To address this market opportunity,GYMCL launched a high-powered boat engine project in 2019. The new boat engine optimizes the existing design of the Yuchai model YC6MJ engine with innovative technology tailored for the yacht-class engine requirements.

A number of innovative technologies were integrated into Yuchai's unique core technologies in developing the YC6MJ marine engine. These innovations have resulted in the YC6MJ marine engine's kilowatt-to-liter power being increased to 50.1kW/L,with a weight-to-power ratio of the YC6MJ at 2.0kg/kW,and the volume-to-power ratio has reached 0.003m3/kW.

After the completion of bench testing,the marine YC6MJ model will quickly enter the OEM certification phase.

Mr. Weng Ming Hoh,President of China Yuchai,commented,"We are again using our extensive engine expertise and broad product breadth to fill a domestic Chinese market opportunity. The YC6MJ engine will deliver to our customers advanced yacht-class engine performance."
