Amid the growing market demand for fuel-efficient motor vehicles, the demand for diesel engines has been expanding even in the field of small-sized popular motor vehicles as the power plant for passenger cars, not to speak of trucks, thanks to the vibration and noise prevention technology which has made great strides in recent years, in addition to the diesel engine's inherent fuel economy. Under these circumstances, recently we at DAIHATSU have developed the Type CL diesel engine, the smallest three-cylinder, one-liter, diesel engine ever produced in the world (hereinafter referred to as Type CL engine). This newly developed engine has been mounted on our "New Charade" which is classified as a minicar. The Type CL engine is a swirl chamber type diesel engine with a displacement of 993 cc. It is not only a high-performance diesel engine capable of delivering a maximum output of 27 KW and a maximum torque of 60 Nm, but also one in which the greatest efforts have been exterted to reduce vibration and noise levels. This paper describes some of the problems we encountered and the improvements we have made in our pursuit of effective control methods of vibration and noise in a three-cylinder diesel-powered passenger car, in connection with vibration and noise characteristics of the three-cylinder diesel engine as the source thereof as well as their control measures taken at the engine side and the anti-vibration and noise-insulating measures taken at the vehicle body side.
