i was hoping for more of a discussion than answers......
this is to do with my uni project which is on engine testing.
i have 2 fuel injectors on each head of the engine (very old engine) and theres supposed to be 2 the same pressure.... and 2 faulty ones at different pressure.
anyway ive done the testing and im a bit stuck. i have data in a sophisticated system at uni and some things dont add up.
for a start the pressures/energy avalailable in the injectors are not equal. this is for the signature in the testing.
the injector pressure was both set using a test bed. but it seems the injector on no1 cyclinder has less energy present and smaller pressure values, where as the other injector has higher values than it should.
basically what im hoping to hear from you guys would be.....
this is due to
1) fuel flow...... the mass flow rates arent identical so nor will the readings be.
2) 2 injectors are never alike.....
3) temperature of the engine plays a part in the fuel flow/combustion.
4) one injector will compensate for the faulty injector
so people whove done calculations on fuel flow/know about fuel flow do you have any info for me as to how fuel problems arise??
