来源:http://www.lutongqixiu.com/ 日期:2019-07-17 发布人:admin
  《汽车发动机性能试验方法》规定了汽车发动机在台架上所进行的动力性、经济性及其他重要性能的试验方法。它适用于汽车用往复式内燃机,包括四冲程及二冲程、水冷及风冷、增压及非增压的汽油机和柴油机。具体包括下列11项性能试验。
  The Test Method of Automobile Engine Performance stipulates the test method of power, economy and other important performance of automobile engine on the bench. It is suitable for automotive reciprocating internal combustion engines, including four-stroke and two-stroke, water-cooled and air-cooled, supercharged and non-supercharged gasoline engines and diesel engines. It includes the following 11 performance tests.
  ①一般性起动试验。评定发动机一般起动性能。
  (1) General starting test. Assess the general starting performance of the engine.
  ②柴油机怠速试验。评定柴油机怠速稳定性。
  (2) Idle speed test of diesel engine. Evaluation of idle speed stability of diesel engine.
  ③汽油机怠速试验。评定汽油机怠速稳定性及怠速排放量。
  (3) Idle speed test of gasoline engine. To evaluate the idle stability and idle emission of gasoline engine.
  ④功率试验。评定发动机在全负荷下的动力与经济等性能。
  (4) Power test. Evaluate the power and economic performance of the engine under full load.
  ⑤负荷特性试验。在规定转速下,评定发动机部分负荷的经济性。
