Do you need a boost compensator?

What is the purpose of a boost compensator?

The boost compensator is so designed as to adjust a fuel injection amount in proportion to a boost intake pressure or a boost pressure supplied to the engine from the supercharger.

What does a fuel compensator do?

A boost compensator for controlling the position of a control rack of a fuel injection pump to supply fuel to an internal combustion with a supercharger in response to a boost pressure to be applied to the engine is described.

How do you test a boost compensator?

Remove your boost sense line between your intake manifold and the top of your injection pump (be sure to plug the hose). If you notice a difference then your compensator is probably working OK, if you don’t notice any change then your compensator isn’t working correctly and isn’t allowing your pump to open right up.

What is an aneroid compensator?

Aneroid (boost compensator) adjusts fuel pre boost. Fuel screw delivers fuel at boost. You can adjust the boost compensater diaphram to get more fuel with boost as I did with mine.

How does a boost compensator work?

Boost Compensators

A ‘Compensator’ is designed to modify the pump in a 3D fashion dependent on this extra flow/pressure the turbo provides. … This increases the amount of fuel delivered depending on the boost pressure pushing down on it. Without the boost compensator tuning on a turbocharged engine would be very limited.

What is a boost diaphragm?

Boost diaphragms are used to automatically increase the fuel supply as the turbo pressure increases. Symptoms of a split diaphragm are usually loss of power and possibly pressurising of the fuel tank. Some early pumps used a vacuum advance mechanism which also utilised a rubber or leather diaphragm.

What is engine compensator?

The intention of the compensator is to smooth out the rough pulses that the engine creates under certain load situations (think about when you lug the engine and it bucks back and forth) and prevent them from being transmitted through the drivetrain.

Can you tune a diesel engine?

Modern diesel engines have many computerised components, which allow a mechanic to easily adjust their settings. That’s why so many people love diesel vehicles because they can match your personal requirements. Tuning is done through the diesel ECU (Electronic Control Unit) and is relatively fast and straightforward.
