China's Yuchai International Limited has announced that its subsidiary, Guangxi Yuchai Machinery Company Limited (GYMCL), just unveiled China's first-ever Euro VI-compliant diesel engine for heavy-duty trucks.
Based on a GYMCL 8.4-liter oil-burning mill, the Euro VI-compliant engine was recently assessed at Tianjin's Automotive Test Center. The results show that the engine has NOx emissions of 307.3 mg/kWh and particulate emissions of 6.5 mg/kWh, well below the Euro VI limits of 400 mg/kWh and 10 mg/kWh, respectively.
GYMCL lists these three emissions-reducing features:
- A proprietary low-temperature combustion technology which reduces the fuel injection pressure requirement hence improving the life span of the fuel injection system and other core parts of the engine;
- The use of medium-intensity cooled exhaust gas recirculation technology resulting in a clean and economic combustion process.
- The use of selective catalytic reduction technology combined with diesel particulate filter regeneration capability to reduce urea consumption during the after-treatment process resulting in cost savings to end-users.

Singapore, Singapore, July 4, 2011 – China Yuchai International Limited (NYSE: CYD) ("China Yuchai" or the "Company"), announced today that its main operating subsidiary, Guangxi Yuchai Machinery Company Limited ("GYMCL"), recently introduced China's first prototype diesel engine compliant with Euro VI emission standards. As China's first Euro VI-compliant automotive diesel engine, GYMCL's heavy-duty model YC6L-60 diesel engine has set another milestone in its history of technological achievement.
At a press conference hosted by GYMCL at its offices in Yulin City, Guangxi Province, the National Passenger Car Quality Supervision and Inspection Center (Tianjin Automotive Test Center) released the test results of the YC6L-60 engine which was jointly developed over a four-year period, between GYMCL and researchers from Tianjin University's National Key Laboratory of engine combustion. The results indicate that the nitrogen oxide emissions and particulate matter emissions of the YC6L-60 were well below the Euro VI emission requirements hence meeting the Euro VI emission standard. There are three key features of GYMCL's YC6L-60 engine: (a) a proprietary low-temperature combustion technology which reduces the fuel injection pressure requirement hence improving the life span of the fuel injection system and other core parts of the engine; (b) the use of medium-intensity cooled exhaust gas recirculation (EGR) technology resulting in a clean and economic combustion process; and (c) the use of selective catalytic reduction (SCR) technology combined with diesel particulate filter (DPF) regeneration capability will reduce urea consumption during the after-treatment process resulting in cost savings to end-users.
Since its introduction in the European Union (EU) in 2009, the Euro VI emission standard is, by far, the most stringent emission standard in the world. As the EU has announced plans to implement the Euro VI emission standards beginning in 2013, most European engine producers have been actively developing their products accordingly. The introduction of China's first Euro VI-compliant diesel engine by GYMCL demonstrates its world-class research and development capabilities.
