抄録

Many four-stroke diesel engines, whose output has been increased by about 15% over the conventional naturally aspirated engines basing on the so called "Exhaust Impulse Principle", have been manufactured. At present 150000 B.HP of these engines have been used without any particular trouble owing to application of this principle. There are two different methods to utilize exhaust pulse ; i.e. "Self cylinder impulse method" and "Other cylinder impulse method". The engine, to which the former is applied, has been equipped with exhaust pipes, and negative pressure occurs in the exhaust pipes during 120 deg-of crank revolution angle near top dead centre, the later utilizes the exhaust impulse caused by the adjacent fired cyinder. Theoritical brief method is developed for calculating the pressure change in the exhaust pipe. Design method and data, for the former type of engines and special expansion tanks to control exhaust pipe length, are given. Concerning the latter method, 2nd report is expected to be prepared.
