Type of start injector fitted to vehicle depends on engine
type. Identification number (last three digits of part number)
is stamped on side of injector .
Injection time is controlled by thermal timer
B
19 ET: injection time is also controlled via an impulse
relay which causes extra
fuel to be injected during warm
stqrts.
Impulse
relay engages injector after approx. 1.5 secs.,
after which : injection 0 .1 secs . - pause 0.3 secs. -injection
