EXHIBIT INDEX 1.1 Press Release of the Company dated May 11, 2005.

Exhibit 1.1 CHINA YUCHAI INTERNATIONAL LIMITED 16 RAFFLES QUAY #26-00 HONG LEONG BUILDING SINGAPORE 048581 TEL : (65) 6220 8411 FAX : (65) 6226 0502 FOR IMMEDIATE RELEASE CHINA YUCHAI INTERNATIONAL LIMITED ANNOUNCES GOOD PERFORMANCE FOR Q1 2005 SINGAPORE, MAY 11, 2005 - China Yuchai International Limited (CYI) today announced good performance for the quarter ended March 31, 2005 with net income of Rmb173.6 million (US$21.0 million) as compared to net income of Rmb195.1 million (US$23.6 million) for the same period in 2004. Net sales of Rmb1,761.0 million (US$212.8 million) for the quarter ended March 31, 2005 represents an increase of 12% compared to the same period last year of Rmb1,577.1 million (US$190.5 million). Total unit sales of 70,933 diesel engines for the quarter ended March 31, 2005 was 10% higher than the same period last year of 64,401 diesel engines. The overall gross margin of 28.2% for the quarter ended March 31, 2005 has declined by approximately 4.1% as compared to 32.3% gross margin for the first quarter of 2004. This decline was mainly due to the change in the product sales mix arising from increased sales of the lower margin 4-series light-duty engines and higher raw material costs during the first quarter of 2005. For the quarter ended March 31, 2005, selling, general and administrative expenses increased by approximately 7%, due mainly to higher transportation and other operating expenses. For the quarter ended March 31, 2005, trade account receivables and inventories increased as a result of higher sales volume and normal seasonality factors. Cash balances have decreased and bank borrowings have increased for the quarter ended March 31, 2005 mainly due to increased capital expenditure payments and higher working capital requirements during the first quarter of 2005. Basic and diluted net income per share for the quarter ended March 31, 2005 was Rmb4.91 (US$0.59) compared to a basic and diluted net income per share of Rmb5.52 (US$0.67) for the same period in 2004. Mr Philip Ting, Director and CFO mentioned that "the increase in unit sales of diesel engines by approximately 10% as compared to the same period of last year was primarily due to the continued growth in demand for trucks and buses in China. The Chinese government is increasing expansion of the new highways and toll roads which we believe led to this growth in Q1 2005. Yuchai has seen increasing levels of acceptance of the new super heavy-duty diesel engine - 6L/6M (previously called 6113) and the management believes that the future of this engine remains to be very positive arising from demand for bigger trucks and buses."
