在炎热的夏季,工程机械都在高温、多尘条件下作业,如操作手不按要求使用、保养涡轮增压柴油机,会导致油耗上升、功率下降。为了保证涡轮增压柴油机在夏季有良好工况,要求操作手严格按照要求使用。(1)使用要求①启动增压柴油机后,应低速空转3～5min,必须待机油压力升高、达到一定温 In the hot summer months, construction machinery are working under high temperature and dusty conditions. If the operators do not use the valves as required, maintaining a turbocharged diesel engine will cause the fuel consumption to rise and the power to drop. In order to ensure that turbocharged diesel engines have good working conditions in summer, operators are required to use them strictly according to requirements. (1) Requirements ① After starting the turbocharged diesel engine, it should be idled for 3 ~ 5min at low speed, the pressure of the standby oil must be increased to a certain temperature
