ASTM D613 – Cetane Number

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 of oil in the gage or combustion chamber. As an example, an engine located where the barometric pressure is mm Hg would be expected to have a compression pressure of approximately kPa 6 20 psi.

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 pump gallery also connects to the flow-rate buret through an air trap which is fitted with a drain valve. Any cetane number ending in exactly x613 in d63 second decimal place shall be rounded to the nearest even tenth number; for example, round To adjust, loosen the locknut and change the length of the connecting screw appropriately and then relock the nut.

Inspect the big end bearing shells and replace if wear d63 indicated. See Appendix X3 for handwheel assembly reworking instructions. Valve Seat Inserts, Intake and Exhaust: Tighten the lock nut hand-tight to hold the key in place.

Except for electromechanical pickups, use of ultrasonic bath equipment has been demonstrated to be effective and c613 of some cleaning solutions can also be beneficial. The engine is belt connected to a special electric power-absorption motor which acts as a motor driver to start the engine and as a means to absorb power at constant speed when combustion is occurring engine firing. Your comments will receive careful consideration at a meeting of the responsible technical committee 1, which you may attend.

The parameters which shall be indicated are as follows: Piston Pin to Bushing Clearance Warning—Do not allow the fuel pump to run dry, except during the momentary periods required to switch from one fuel to another, because the fuel pump is partly dependent on fuel for lubrication.

This releases the mechanism and permits the larger handwheel to be turned so that the d13 compression plug can be properly moved in or out of the precombustion s613. Height of the foundation should be minimized so that the fuel sample reservoirs are at an elevation for safe pouring of fuel oil by operators of average height without the use of a raised platform or step in front of the engine.

Paul Avenue, Waukesha, WI A water manometer is a satisfactory alternative. Opening the valve should drastically change the exhaust discharge configuration while the engine is operating at standard conditions asttm determine if there is an effect.

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

Engine speed when combustion is occurring shall not be more than 3 rpm f613 than that for motoring without combustion. A typical buret is illustrated in Fig.

However, the relationship to the performance of such materials in full scale engines is not completely understood. Record the resulting ignition delay values for each of the reference aetm blends.

For more detailed information regarding sstm hazards, refer to the appropriate Material Safety Data Sheet MSDS for each of the applicable substances to establish risks, proper handling, and safety precautions. If pitting or corrosion of these components is observed, the parts should be replaced.

The variable compression plug mechanism should be kept free-working, and easily adjusted.

Manually rotate the crankshaft through several revolutions so that the cylinder is centered. The selected fuel is delivered to the fuel pump inlet and fills the fuel sump or gallery. Install d6613 cylinder over the piston so that it is seated on the cylinder base gaskets.

Engine operation on the purge sequences will afford sufficient time to completely displace the fuel in the line from the injection pump to the injector. Continued D — 05 A3. The cetane method test procedure requires that all fuels operate at a asfm ignition delay period and therefore changes in handwheel setting are necessary.

It is screwed in and out of the head by the handwheel to effect changes in compression ratio.

This setting is made at the factory and there is no provision for field adjustment.
