What is the fuel pump timing in diesel engine?

What is the fuel pump timing in diesel engine?

A fuel pump timing is nothing but the timing at which fuel is injected into the cylinder. This time is ideally from 10-20 BTDC ( Before Top dead center ) to 10-20 ATDC ( After top dead center ). A TDC is the the top dead center or simply speaking the top most position in cylinder a piston can move to.

How do you check the timing on a fuel pump?

By removing deflector from fuel pump

1. Take out deflector on both sides of the fuel pump.
2. Put hand torch on one side of pump and mirror on the other side.
3. The light from torch will be visible on the mirror.
4. Turn the engine so that the unit to be check is toward the TDC of compression (at plunger upstroke)

How will you check and adjust the injection pump timing?

You can check the injection timing by measuring the injector pump’s stroke at TDC using a dial indicator.

How do you check the zero setting on a fuel pump?

ZERO SETTING means, the fuel plunger helix should be inline with the spill port so that there is no injection. This is ensured while assembling the rack in the sleeve of the plunger. One gear of the sleeve is slightly cut which should go in between the two cut gears of the rack, which ensures zero setting.

What kind of horsepower does a Nissan SD33 have?

Revisions included the use of three piston rings instead of five, piston oil squirters and spin-on oil filter instead of a paper cartridge type. The Nissan SD33 produced 70 kW (95 PS, 94 HP) and 220 Nm (22.4 kg-m; 162 ft-lb) of torque.

What are the bear bearings on a Nissan SD33 motor?

Bearings are a precision type, steel-backed trimetal shell. The Nissan SD33 motor has an aluminum alloy piston for high strength, lightweight and good heat conductivity; three compression and two oil control rings (before 1983) and two compression and single oil control ring (after 1983), they are chrome-plated for long service life.

What is the compression ratio of the SD33T?

The cylinder bore is 83 mm, piston stroke is 100 mm and the compression ratio rating is 21.6:1. The SD33T has a one-piece high-strength cast iron cylinder head, special cast-iron valve inserts are shrink-fitted. It has high-quality cast iron camshaft, lobes are specially processed to improve hardness and durability.
