Warning—Chemical cleaning solutions are poisonous and may be harmful d63 fatal if inhaled or swallowed. Check that any bubbles are purged at the zero tip and refill the tip, if necessary. Restricting the pickup hole by pressing a cloth not paper wiper against the opening will aid in removing satm entrained water. Calibration and Engine Qualification 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 calibration marks on the buret are in 1 mL increments so that fuel flow rate is easily measured by noting the time required for engine consumption to lower the buret fuel astj by a specific number of mL. Connect a piece of plastic tubing to the fuel line air trap connection and submerge the other end of this tube in a small container of diesel fuel oil such that bubbling in the container may be observed when appropriate.
The piston should be used to square the ring in the bore about 1 in. X613 quieting ramps are flat spots in the contour which occur at 0. Determine this point by several trials noting the flywheel crank angle for each to establish an average point.
However, depending on the severity of testing, the process may need to be performed asrm frequently and some testing facilities make it a practice to install a cleaned and checked injector prior to each unit startup. The care used in asym inspection, adjustment, and especially the overhaul of the combustion chamber components is a major factor in achieving these aims.
Turn the injection timing micrometer clockwise as viewed from in front of the engine to decrease the indicated number of degrees of advance. Piston Pin to Bushing Clearance The solution should be kept at this temperature for approximately 30 min and drained. Note the flow-ratemicrometer reading for reference.
ASTM D – 01 Standard Test Method for Cetane Number of Diesel Fuel Oil
The selected fuel is delivered to the fuel pump adtm and fills the fuel sump or gallery. This is a trial and error procedure whereby the pressure is checked by use of the injector tester after each screw adjustment accompanied by relocking of the locknut B.
Warning—In addition to other precautions, compression pressure testing using a compression pressure gage should be completed in as short a period of time as possible to avoid the possibility of combustion occurrence due to the presence of any small amount aatm oil in the gage or combustion chamber. Referenced Documents purchase separately The asgm listed below are referenced within the subject standard but are not provided as part of the standard.
During this period each exchange sample was rated twice on the same day by the same operator on one engine in each of the Member ashm. Analyzed graphically, the respective sample standard deviations were plotted versus cetane number. When an interference angle approach is utilized, lapping may be performed but extreme care must be taken to exert very light pressure to prevent creating a groove in the valve face.
Users of this standard are expressly advised that d6613 of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Changing handwheel setting changes the ignition delay period. Low handwheel readings correspond to high compression ratio conditions while high handwheel readings reflect low compression ratio conditions.
If the unit ast placed on an industrial building floor of reinforced concrete approximately mm or 8 in.
ASTM D613 – Cetane Number
Crankshaft Journal Diameter 2. Vapors may cause flash fire. Vacuum shall not exceed mm 10 in. Waukesha Engine Division Part Numbers are included in parenthesis after the items where appropriate. D — 05 with commercial glycol-based antifreeze added in sufficient quantity to meet the boiling temperature requirement shall be used when laboratory altitude dictates.

If any disassembly is attempted x613 the field, it should be performed by a qualified fuel injection equipment specialist. A typical spray pattern is illustrated in Fig.
Bottom delivery from the buret is from a straight tubing bib which is connected by plastic tubing to a three-way valve similar d13 that shown in Fig. Balancing Shaft, 2 required A. Flush lubricate the bearings if the unit is equipped with field lubrication fittings.
Do not touch the critical lapped surfaces with bare fingers because body acids can cause undesirable etching. Commercial injector nozzle testers which include a aztm pressure cylinder, fuel reservoir and pressure gage are available from several sources as common diesel engine maintenance equipment.
Complete the cranking so that the flywheel is positioned at top-dead-center on the compression stroke to minimize the load on the absorption motor when the engine is started. See Appendix X2 for a suitable procedure to determine if resonance exists. Scrupulous cleanliness must be observed to prevent dirt or moisture from causing damage.
Calculation of Cetane Number Please help us to share our service with your friends. See Annex A4 for procedural detail.
See Specification E Connecting Rod Assembly BA Any cetane number ending in exactly 5 in the second decimal place shall be rounded to the nearest even tenth number; for example, round Secondary reference fuels are supplied in bulk containers of 5 or 55 U.
