Bottom delivery from the buret is from a straight tubing bib which is connected by plastic tubing to a three-way valve similar to that shown in 6d13.

ASTM D – 01 Standard Test Method for Cetane Number of Diesel Fuel Oil

Significance and Use 5. Engineering asstm technical support for this function is required, and the user shall be responsible to comply with all local and national codes and installation requirements.

The setting should be checked each time the nozzle is disassembled and cleaned. When making replacements always r613 a complete mated assembly. Balancing Shaft, 2 required A. The injector nozzle can be a very critical factor and this should be the first item checked or replaced to achieve rating compliance. For more specific warning statements, see Annex A1. Set the flywheel to a position at any point on the intake stroke. Clockwise rotation of the handwheel viewed from in front of the engine increases C.

A slight shifting of the handwheel to achieve slot lineup will not affect the indexing. Check this setting using an injector nozzle bench tester, each time the nozzle is reassembled and after cleaning. This standard has been approved for use by agencies of the Department of Defense. Replace the cylinder if the internal diameter at the area of maximum wear is more than 0.


Note astn injection-timing-micrometer reading for reference.

Hg have not been established. Warning—Do not allow the fuel pump to run dry, except during the momentary periods required to switch from one fuel to another, because atm fuel pump is partly dependent on fuel for lubrication.

The average standard deviation for each cetane number level has been multiplied by 2.

The interval between top overhauls varies and depends primarily upon the severity of the conditions x613 which the unit is operated. An American National Standard Designation: Inspection for possible nozzle pintle drip as well as spray pattern should be observed when making this setting.

The lift specification is the same as for the intake valve.

ASTM D613 – Cetane Number

Work Item s – proposed revisions of this standard. D — 05 Designation: A commercial multifunctional water treatment material should be used in the coolant to minimize corrosion and mineral scale that can alter heat transfer and rating results. The fuel switching shall be as illustrated in Fig.

Typically this inspection could be part of a top overhaul.

Measure with the flywheel at rest and then with the flywheel lifted using an appropriate lever, if the difference in the measurements exceeds 0. The cetane method test procedure requires that all fuels operate at a specified ignition delay d163 and therefore changes in handwheel setting are necessary.


Wash each part in a clean diesel fuel oil and wipe it with a clean, lint-free cloth.

An angled passage, 0. Before removing the suction bulb, quickly move the selector-valve to a position between the tank marks. If the points do not fit an easily defined smooth curve, the injector nozzle is probably suspect and may require further cleaning maintenance or replacement. The adjustable-length valve push-rods shall be set so that the valve rocker adjusting screws have adequate travel to permit the final clearance setting.

Changing the point of mesh of the cam gear with respect to the crankshaft gear by one full d6133 tooth makes a 9. Warning—Lubricating oil is combustible, and its vapor is harmful. Use of a ring compressor tool over the piston rings is advisable despite the cylinder chamfer.

The exhaust rocker bushing must have a hole to permit pressurized oil to reach the distribution channel on the top rocker surface.
