Research Note 4-Feb-2008

PLACE:Engine lab AIM:start the engine

Do:
1 start the coolant water circulation system and coolant heating system. wait until the pump make noise like "peng!peng!"
2 oil temperature is 60度; coolant water temperature is 80 (set up,90度 reality)
3 borrow oscilloscope and connect with the spark system and fuel duration controler
4 turn on the computer

Problem:
1 the oscilloscope is not showing the real time 喷油时刻,喷油持续期,点火时刻
2 no ignition of engine, only the monitor rotating
3 the wrong pump and fuel is out
4 can't measure and control the 喷油时刻,喷油持续期
5 no reaction on pc

Analysis:
1 示波器连线有误,
2 喷油过浓或者过稀,以至于造成熄火或者失火miss fire
3 点火时刻不对
4 火花塞处有积碳

use the intake heater
the temperature is too low to start
