QSK19 diesel engine electronic control fuel supply system an

<div class=:510- 700 horsepower ; the speed 1800-2100r/min . The diesel engine is widely used in northern China Heavy Duty Truck TR60 mine car .
diesel engine electronic control system is a sophisticated and complex system , the performance of the diesel engines have a significant impact , mainly diesel engine fuel economy and emissions have greatly improved . Diesel electronic control system to improve the performance of the car at the same time , diesel engine maintenance and repair become complicated.
electronically controlled fuel supply system composed of
QSK19 series diesel engine , electronically controlled fuel injection system consists of three basic component parts , namely: input (switches and sensors ) , ECM ( input signal analysis) and actuators ( control valve assembly in accordance with the ECM output signal action ) , shown in Figure 1 .

FL513 series air-cooled diesel engine air filter maintenance

<div class=Therefore, the required careful maintenance of air filters, which extend the engine life is very important.
into the tracheal flange and sealing of the joints to check, also belong to the range of air filter maintenance.
the life of the air filter core in a timely manner to exclude dust collector (see Figure 1-2) in the dust. If you do not rule out the dust, the cartridge will soon be blocked. Therefore, never allow the dust collector set full of more than half the dust. In the case of large dust content, every day should be a dust collector to clean up.
with dust emission valve air filter can cancel the maintenance, but must always clean up the valve for dust port for dust.
(1) dust collector cleaning
loosen the clamp 1, the dust collector 2 together went together to the end cap 3. Remove the end cap, pour out the dust from the dust collector. Reassemble in the opposite order. Note that the groove on the end cap on the dust collector flange aligned with each other (see figure, arrow); when the level of air filter installation should be made on the
(2) the maintenance of the air filter
must be noted that the maintenance of air filter maintenance indicator or control lights, frequent disassembly of the filter will damage the casing 6 and the cartridge 5 between the ring 7. Therefore, only when necessary to clean or replace filter. But at least replaced once a year or diesel severe smoke at any time to replace the air filter.
diesel engine downtime, maintenance indicator can clearly see the red air filter maintenance.
air filter maintenance 5 should be replaced after 5 times. Safety tube (11) air filter maintenance, also need to be replaced, but change at least every two years a safety tube.
after the end of the air filter maintenance, maintenance indicator light continue to flash, you must replace the safety tube.
(3) air filter cleaning
① temporary treatment: with the palm of your hand gently several times to beat the filter face or soft surfaces, dust vibration fall. Filter face shall not be damaged in this process.
② strong cleaning: do not exceed 0.5MPa dry air pressure of the filter purge until you purge clean. Note: The purge must not harm the filter paper.
③ liquid cleaning: adding an appropriate amount of pure detergent in warm water, the air filter into the water, swaying back and forth cleaning, and then again in water for cleaning, dry water can be used. Note: Do not use gasoline or hot water.
(4) after the air filter check
filter cleaning is completed, you should carefully check on the filter, if there are quality defects to be replaced.
after the end of the maintenance, the maintenance indicator disappeared zero, you can press the return button (Figure 2-2), the maintenance instructions to disappear. Otherwise, it should be re-maintenance.
