Due to the absence of common understanding among the naval architects,engine-builders and marine engineers,about the definition of marine diesel engine power rating,difficulties aroused by power deficiency in diesel-installations on board were frequently eneountered in service.This paper deals with diesel engine power rating from manufacturing and service point of view.The manufacturers should rate their engines into three ranks:maximum rating,nominal rating and over-nominal rating. The marine engineers should rate their auxiliary engines into two ranks,namely,normal service rating and overload rating,and their main propulsion engines into trial trip rating,maximum service rating and normal service rating.Scientific definifion of these ratings are explained and their empirical relati- ons are also given. The bases of nominal rating are standard ambiant atmospheric conditions and installation condi- tions.The author proposes that standard ambiant atmospheric conditions should be based on the mean conditions in the test shop of the most diesel engine factories throughout the country.However,the naval architects should rate their engines according to the particular conditions of the appointed navigation zone and the kind of service to be attained.Numerical data of ambiant atmospheric conditions and installation conditions proposed are:736mmHg.,20℃,70% humidity,and less than 150 mm WG vacuum in the intake air system,30～300mmHg back pressure in the exbaust system.The calculation method in practice for correcting nominal rating and specific fuel consumption according to the variations of ambiant atmospheric conditions differ largely one another.For non-supercharged diesel engines,new correction formulas according to constant fuel pump rack and constant fuel/air ratio respectively are recommended in the paper.The results of comparison of these proposed fornmlas with others in practice and also with published test data show that the recommended formulas are more reasonable,although the correction is still slighly too high. The ambiant conditions on board differ largely with those in test shop,so the determination of service rating depends upon the specification of ambiant atmospheric conditions in the machinery compartment.Three kinds of standard ambiant conditions in machinery compartment,for high sea,east- south sea and north sea-going ships respectively,are given in this paper.These numerical data are deter- mined by statistical method.In the determination of service rating,the influence of wear,rpm.,insta- bility and power reserve must be considered.Its empirical coefficients are introduced.Generally,the normal service rating for auxiliary engines is about 75～82% of the nominal rating from manufacturer and 70～99% for the main propulsion engines.

船用柴油機(jī)功率的定義在設(shè)計、制造和使用各方面缺少統(tǒng)一的理解,以致使用時常常出現(xiàn)柴油機(jī)功率滿足不了需要的問題。本文提出船用柴油機(jī)功率分級應(yīng)從制造及使用兩方面分別加以考慮:從制造方面可分為最大功率、額定功率和超額功率三級;從船上使用方面,驅(qū)動發(fā)電機(jī)的付柴油機(jī)可分為持久功率及超額功率兩級,而推進(jìn)用的柴油機(jī)則應(yīng)分為試航功率、最大使用功率和正常使用功率三級。本文給出了上述各種功率的科學(xué)定義和經(jīng)驗(yàn)比例。額定功率的標(biāo)定基礎(chǔ)是標(biāo)準(zhǔn)大氣條件和安裝條件,標(biāo)準(zhǔn)大氣條件的選擇原則應(yīng)根據(jù)國內(nèi)大部份柴油機(jī)車間的條件而定,而使用者別應(yīng)根據(jù)具體航區(qū)和船的用途重新標(biāo)定持久使用功率。本文建議的標(biāo)準(zhǔn)大氣條件為736毫米汞柱,20℃和70%濕度,并提出進(jìn)氣系統(tǒng)真空度不超過150毫米水柱、排氣背壓應(yīng)為30～100毫米汞柱。目前使用的各種額定功率及耗油率修正計算方法差別較大,本文對非增壓柴油機(jī)分別按每循環(huán)供油量不變及燃燒空氣過量系數(shù)不變兩種情況提出了新的修正計算公式。運(yùn)用本文介紹的公式計算結(jié)果與試驗(yàn)結(jié)果,比較表明本文建議的公式比較合理,但仍略偏于保守。船上機(jī)倉內(nèi)的大氣條件與工廠條件相差較大,投使用功率的選定應(yīng)以機(jī)倉大氣條件為準(zhǔn)。作者根據(jù)統(tǒng)計提出適合在遠(yuǎn)...
