1.电控柴油机必然发展的原因(1)排放法规为了减少机动车对大气的污染,各国都制定了越来越严格的排放法规。开发和生产的发动机应符合曰益严格的排放标准,这成为各生产商的首要目标。目前,欧洲对公路机动车已经开始执行欧洲4号排放标准,美国和日本也都开始执行类似的标准。对非公路机动设备,如工程机械、发电机组、矿用车、林业机械、农业机械、轮船等,欧美等国 1. Electronically controlled diesel engine inevitable development reasons (1) emission regulations In order to reduce the vehicle’s atmospheric pollution, all countries have developed more stringent emission regulations. Engine development and production should meet the increasingly stringent emission standards, which became the primary goal of each manufacturer. At present, European road vehicles have started to implement the Euro 4 emission standard, and similar standards have also started to be implemented in the United States and Japan. On non-road mobile equipment, such as construction machinery, generating units, mining vehicles, forestry machinery, agricultural machinery, ships, etc., Europe and the United States and other countries
