How to start the engine
Several factors affect engine start, for example:
z The power of the batteries
z The performance of the starter motor
z The viscosity of the lubricating oil
z The installation of a cold start system
Diesel engines need a cold starting aid if they are to start in very cold conditions. Normally, your machine will
be fitted with the correct equipment for your region of operation.
Perkins engines can be equipped with various cold starting systems. For the 3.152 Series engines these
systems are:
Fuelled starting aid
An electrically operated device which ignites a specific amount of diesel fuel in the induction manifold in order
to heat the induction air.
Port heaters
These electrical devices are fitted in the induction manifold and heat the induction air. They are operated
automatically when the starter motor is engaged. When these devices are fitted, the start procedure for a cold
engine is the same as that given for a cold engine start without starting aids.
Start pilot
A hand pump is used to inject a cold start fluid into the induction manifold through an atomiser. The cold start
fluid ignites at a lower temperature than diesel fuel. The cold start fluid is contained in a separate reservoir.
Certain models use a push button to actuate a solenoid which releases the cold start fluid from an aerosol
container.
KBi
This system uses an aerosol container filled with a cold start fluid. The fluid is released by a solenoid, which is
operated by a push button. The cold start fluid is sprayed into the induction manifold through a nozzle. The
cold start fluid ignites at a lower temperature than diesel fuel.
Caution: If the engine has not run for several weeks, see Caution on page 5.
