一、前言大发柴油机公司生产船用、陆用中小型的中高速柴油机,这些机型逐年改变,从非增压机发展成PS型,继而又发展高功率、小体积的DS型,并各自形成系列机。石油危机后,对柴油机的要求发生了重大变化,时代要求降低油耗、能烧劣质燃油占据了主要地位。为此,改进柴油机结构、提高热效率、烧劣质燃油、余热回收、轴带发电机、大直径螺旋桨等各种节能技术的应用,从而使燃油消耗率不断降低。
I. INTRODUCTION Daihatsu Diesel Engine Co., Ltd. manufactures medium and high-speed diesel engines for small and medium-sized ships and land use engines. These models have been changing year by year. From non-turbochargers to PS models, DS models of high power and small volume have been developed and series of machines have been formed . After the oil crisis, the requirements of diesel engines have undergone major changes. The era requires reducing fuel consumption and burning inferior fuel occupies a major position. To this end, to improve the diesel engine structure, improve thermal efficiency, burning low quality fuel, waste heat recovery, shaft generator, large diameter propeller and other energy-saving technologies, so that the fuel consumption rate continues to decrease.
