CY4102BQ Diesel Engine General Situation Model CY4102BQ is a high speed diesel engine developed by DCD on the reference of Japan ISUZU 4BD1 diesel engine designing ideology and concept, the launch of this engine meets the demand of auto market to 2-3 ton light-duty diesel vehicles. In the meantime, due to the change of international finance market, this makes some Southeast countries switch over to purchase 2-3 ton light-duty diesel vehicles from China,which greatly opens up the overseas market for CY4102BQ diesel engines CY4102BQ diesel engine features high power index and good economy. It is the ideal power for 2-3 ton payload trucks, 6-7m buses, tourist buses and intercity buses as well. According to customer requirements,auxiliary devices such as air brake ,oil brake, air compressor,warm air heater and power steering pump etc.can be installed.
