It also warns that operation significantly above a continuous rating for extended periods can accelerate wear, while excessive underloading can create problems of its own. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That&#8217;s a much better mental model:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Correct load is good.

One published guide describes an A\/continuous rating as allowing rated load and speed up to 100% of the time, while intermittent categories progressively restrict allowable time at maximum horsepower.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So asking whether &#8220;80% load is too high&#8221; without identifying the engine rating is almost meaningless.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Eighty percent of what rating?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For how long?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At what ambient temperature?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At what altitude?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That&#8217;s the engineering question.<\/p>\n\n\n\n<h2 id=\"four-operating-histories-i-would-check-before-buying\" class=\"wp-block-heading\">\u0623\u0631\u0628\u0639\u0629 \u0633\u062c\u0644\u0627\u062a \u062a\u0634\u063a\u064a\u0644\u064a\u0629 \u064a\u062c\u0628 \u0639\u0644\u064a\u0651 \u0627\u0644\u062a\u062d\u0642\u0642 \u0645\u0646\u0647\u0627 \u0642\u0628\u0644 \u0627\u0644\u0634\u0631\u0627\u0621<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When we&#8217;re evaluating a used diesel, I want four records before I get excited about low hours.<\/p>\n\n\n\n<h3 id=\"1-total-fuel-burn\" class=\"wp-block-heading\">1. \u0625\u062c\u0645\u0627\u0644\u064a \u0627\u0633\u062a\u0647\u0644\u0627\u0643 \u0627\u0644\u0648\u0642\u0648\u062f<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Fuel burned is essentially a rough lifetime-work counter.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Not perfect.

duty cycle.<\/strong> Chronic underloading can also create undesirable operating conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So the objective isn&#8217;t &#8220;lowest possible
