How do you turn up a CAV injection pump?
How do you adjust the fuel of a Cav pump? Turn the engine until you reach the curb, then return to the side through the notch. Loosen the two screws by one or two turns, then adjust the fuel with the small notch. In the direction of rotation towards the lean, move away from the direction of rotation to enrich it.
How do I advance my injection pump timing?
Some of the most common ways to advance the timing are:
- Program the ECM. The engine control module is a computer that analyzes information to control your boat’s performance.
- Modify the Fuel Injection Pump.
- Replace the Camshaft.
- Swap Out the Cam Gaskets and Followers.
How do I adjust my fuel timing?
Fuel pump timing can be adjusted by simply adjusting number of shims to the pump base. Add or remove required shims to set required injection timing. For some engines you may also required to manually adjust the relative position of cam with respect to crankshaft to do the job.
What is a CAV fuel filter?
Diesel & Petrol Fuel Filter manufactured by Delphi ‘CAV’. An agglomerator filter which offers efficient fuel filtration via a paper filter element. Water is collected in a clear glass base and drained via a screw in plug, without having to dismantle the unit. Suitable for diesel fuel only with standard element.
What is advance ignition timing?
Ignition timing advancing means that the spark plugs are firing earlier in the compression stroke, farther from TDC. The air and fuel mixture in the combustion chamber doesn’t burn right away. Ignition timing advancing might be needed to allow time to get everything ignited.
Does advancing timing increase horsepower?
The major benefit to advancing the timing of a vehicle’s ignition is increasing the horsepower of an engine. Advancing the ignition timing helps raise the high-end power while reducing the low end. It also helps get the spark past the ignition delay and run at peak power.
What is a CAV pump?
The C.A.V. Fuel Injection Pump is a cam-operated spring return plunger pump of the constant-stroke one pump element per cylinder type. Normally, it is offered as a one-cylinder unit, so that for multi- cylinder engines it is necessary to provide one pump per cylinder.
