Carman scanFor EMS PROfesor
(2)After a current flowed,if a peak(voltage of surge) is low and discharging time is long:
Although electric discharge is well,it causes power reduction because discharging
electric energy (spark) gets weak and long so that combustion timing of fuel gets long
and flame spread leading to combust between fuel particles gets weak
a. Check status of plug (clearance of tip is too small)
b. Check compression pressure of cylinder is low
c. Check the mixture ratio is too rich
More detail refers to chap 6.”6.3 uniform ignition energy to each cylinder.
In 4 cylinder engine , If one cylinder has some troubles, the troubles are made in two cylinders at
the same time. Therefore when measuring wave with Carman scan, choose “one of NO1.and
NO3.” or “ one of NO2. and NO4.” then measure 2cylinders at the same time.
