Q. What is an INJECTOR PRESSURE in heavy vehicles?
Why it is used?
A. Injector pressure i s the pressure at which the fuel can
be injected into the vehicle. In heavy vehicles, injector
pressure is 220 kg/cm square. It is used to set up the
standard fuel injection in the vehicles. With the help of
injector pressure we can calculate the amount of fuel
needed, through the following formula:
Est. Horsepower x B.S.F.C / No. of injectors x duty cycle
= lb/hr per injector
cc = lb/hr x 10.5
