To prevent leakage of combustion gases, this plug, which has no seals or rings, is expanded by action of the locking wheel which is connected to a drawbolt that exerts pressure on a dished and split washer inserted in the plug causing it to expand and clamp the plug in the bore. Check that any bubbles are purged at the zero tip and refill the tip, if necessary. Vapors harmful if inhaled. A water manometer may be substituted.

For volumetric blending, a set of two burets or accurate volumetric ware shall be used d6613 the desired batch quantity shall be collected in an appropriate container and thoroughly mixed before being introduced to the engine fuel system. The average standard deviation for each cetane number level has been multiplied by 2. A resonant condition affects the primary pressure within the system and can affect critical operating conditions.

ASTM D613 – Cetane Number

The exhaust rocker bushing must have a hole to permit pressurized oil to reach the distribution channel on the top rocker surface. The variable compression plug mechanism should be kept free-working, and easily adjusted. Warning—Chemical cleaning solutions asmt poisonous and may be harmful or fatal if inhaled or swallowed. Warning—The pump and timing gear box oil sumps are not connected to each other and the lubrication for the two is independent.

Hg have not been established. The care used in the inspection, adjustment, and especially the overhaul of the combustion chamber components is a major factor in achieving these aims. This handwheel reading scale extends from 0. Rotate the fuel injection timing micrometer so that the advance lever is at full advance nearest to d631.


D — 05 rate-micrometer is set to a typical operating position and the variable timing device lever is at full advance nearest to operator.

ASTM D – 18 Standard Test Method for Cetane Number of Diesel Fuel Oil

If a nozzle is faulty, it is often easily noted by the erratic operation and data scatter of the results obtained aetm the early stages of this procedure. The valve head shall be recessed at least 0.

Asstm px x x x x Add sufficient engine crankcase lubricating oil through the top hole to cause the level to rise to atsm height of the side opening. Any mated parts, such as delivery valve and seat or barrel and plunger assembly, must be kept together. Remove the locating screw from the drum and rotate the drum so that the zero graduation mark is in line with the selected reading from Table 1. Thus, all timing events are referenced to the flywheel crank angle degree readings which occur at a rise of 0.

Note the flow-ratemicrometer reading for reference. D — d6133 in the container of diesel fuel oil. Thank you for interesting in our services. Free Length rotator type Handwheel Assembly: Locate the screw hole in the drum which lines up with the handwheel hub hole and reinstall the locating screw. Discharge tubing diameter shall be as small as practical to 0.

The relationship of test engine performance to full scale, variable speed, variable load engines is not completely understood. Warning—Lubricating oil is combustible, c613 its vapor is harmful. Changing the point of mesh of the cam gear with respect to the crankshaft gear by one full gear tooth makes a 9.

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

Set the flywheel to a position at any point on the intake stroke. Warning—In addition to other precautions, read the compression pressure gage in whatever position it faces without twisting the gage and hose which can distort the readings. The setting should be checked each time the nozzle is disassembled and cleaned. Lubricate moving parts with Asfm 30 engine crankcase lubricating oil before assembly.


See Annex A4 for procedural detail. Flush lubricate the bearings if the unit is equipped with field lubrication fittings.

Oils containing viscosity index improvers shall not be used. Flow rate measurement must then be started almost immediately because the engine will be drawing fuel from the buret and the level in the buret will be falling.

Greater detail is available from the engine manufacturer. If any disassembly is attempted in the field, it should be performed by a qualified fuel injection equipment specialist. D6613 for electromechanical pickups, use of ultrasonic bath equipment has been demonstrated to be effective and heating of some cleaning solutions can also be beneficial.

When the engine is running, the solenoid overcomes the force of the spring and allows the rack to move into contact with the fuel flow rate micrometer. The actual compression ratio is not important but an indication of compression ratio which relates to cetane number is a useful guide for selecting reference fuels to bracket the sample of diesel fuel oil.

The variation in precision with respect to cetane number level for these data is best expressed by a linear regression of the values. Reagents and Reference Materials 8. The fuel switching shall thus be as illustrated in Fig.
