Light-duty commercial vehicles below 3.5 ton National III standard was implemented on July 1, 2008. Though core technology and parts&components deficit, petroleum suitability, service guarantee and other reasons are barriers to commercial vehicles,which make them hard to match National III standard,however,it’s no doubt that it’s National III times now,and competion will be fiercer.
Dachai CA4DC
Low violation, low noise, but needs more maintenance
Technology content: The CA4DC diesel engine is based on Deutz FAW Dachai CA498 diesel engine, adopts BOSCH electrically controlled common rail system and the K coefficient oil atomizer, saves more diesel compared with domestic similar type diesel engines,and it’s in accordance with CKD optimization low-speed characteristic.
CA4DC National Ⅲproduct makes use of German Deutz, Japanese MAE design ideas and the confirmation standard to develop parts&components and CKD,adopts alloy cast iron cylinder body and the integral-type cylinder cover, with high intensity and good rigidity, its vibration noise achieves the international similar products level.
CA4DC diesel engine also has enormous overseas market. Two major light-duty autos export enterprises Shandong Shifeng Group and Shandong Kama Group match the light-duty autos with 3CA4DC diesel engines which exported to South America and the Middle East market.
Chaochai 4102-C3
Economy, but not easy to maintenance.
Technology content: The CY4102-C3 diesel engine is jointly developed by Chaochai and Austrian AVL Corporation, it adopts four valve structure cylinder cover, German BOSCH electrically controlled high pressure common rail fuel delivery system, exhaust gas turbocharger inter-cooled,it’s 4 volve high quality engin in accordance with National III and Euro IVstandard.
Xichai 4DW Fuwei
Great power, widely match.
Technology content: Xichai makes full use of Aochai diesel engine’s experience and technology,turns to Austrian AVL for consultancy,cooperates with Shanghai institute of Internal combustion engine. It has three types,natural aspiration, turbo-charged and the turbo-charged inter cooled,of which, 4DW93-96E3, 4DW93-84E3 reach NationaⅢemission standard,and it is the best low power diesel engine in China.
4DW Fuwei diesel engine has the characteristic of high interchangeability with complete engine,when matching passenger car enterprises want to upgrade,they only need to change diesel engines,not need to change the arrangement of complete auto,which will help reduce the time of passenger car enterprises for products development time and process.
Yuchai YC4F
Quality guarantee, high cost.
Technology content: The YC4F engine is jointly designed by Yuchai and German FEV and the Japanese YAMAHA ,adopts many modern diesel engine scientific research technology achievements. National Ⅲengine adopts American DELPHI electrically controlled high pressure common rail technology, low turbulent flow combustion chamber and many other modern diesel engine technology achievements. At the same time, because it is designed and developed according to National III emission standard,and takes National III and National IV upgrading into consideration ,so it has upgrading potential .
Because Yuchai has carried out massive reliable and compatible development according to the German FEV Corporation machinery development procedure, it is said that the guarantee distance under the maintenance is more than 500,000 kilometers, in view of the fact that YC4F uses the wet cylinder sleeve structure, four cylinder covers make one cylinder cover, with good accessibility, easy to maintenance.
