7、h the new SAE Technical Standards Board Format. Abbreviations have changed to Section 3. All other section numbers have changed accordingly. This manual was originally prepared under the auspices of the SAE Ignition Research Committee by the Spark Plug Rating Engine Standardization Panel of the Airc
8、raft Piston Engine Ignition Subcommittee. In 1974, the Spark Plug Rating Engine Standardization Panel was placed under the jurisdiction of the SAE Electrical Equipment Committee. This manual defines the standard engine to be used in determining spark plug preignition ratings. The engine is known as
9、the SAE 17.6 Cubic Inch1Spark Plug Rating Engine. The background of its design, development, and applications is contained in SAE publication SP-243. 1With the advent of the metric system, the metric notation should be 288.6 cc for the ending displacement. However, since the WHUPLVquite familiar in
10、the industry, it will be retained in that form. SAE INTERNATIONAL J2203 Revised FEB2014 Page 2 of 76 In addition to describing the engine, this manual deals with maintenance and overhaul instructions for the engine. Appendices providing engine manufacturing tolerances, replacement limits, and engine
11、 bill of materials are included. The manual also includes the procedure for rating spark plugs. The 17.6 engine has been used for many years in the spark plug industry to classify spark plugs by their preignition rating. Correlation of these ratings among the various test agencies has been accomplis
12、hed with limited success primarily due to engine variations. This correlation difficulty prompted the Aircraft Piston Engine Ignition Subcommittee of the SAE Ignition Research Committee to investigate methods of standardizing and improving this engine. The Ethyl Corporation (which originated the 17.
13、6 engine) consented to the incorporation of improvements in the engine by SAE. The Spark Plug Rating Engine Standardization Panel, which was established to standardize and improve this engine, consists of persons who are closely associated with the use or manufacture of the engine. The sum of their
14、individual experiences and the many special projects conducted by the panel have been gathered into this manual. Conformance with the engine description and rating procedure included in this manual and the diligent following of the Maintenance, Overhaul, and Operation instructions will result in mor
15、e uniform spark plug rating data from each engine and a closer rating correlation between engines. This manual will be revised periodically to reflect engine improvements that have been developed and thoroughly evaluated. Comments, advice, or recommendations concerning the manual or the engine that
16、it defines will be welcomed by this panel and should be sent to SAE Headquarters for consideration. This Edition of the manual includes only the 5750 / 16047 series engine since it is the newer design and in use at many of the spark plug companies. The older type 5000 series was covered thoroughly i
17、n a previous edition of the manual (publication date, July 1964). The 5750 / 16047 series engine (Figures 1a and 1b) differs from the 5000 series in that it incorporates a Lanchester-type of balancing system consisting of two counter-rotating, chain-driven, counterbalancing shafts, rotating at crank
18、shaft speed, to dampen the unbalanced portion of the connecting rod and piston assembly. NOTE: Shown for illustrative purposes only.

CYLINDER ASSEMBLY The cylinder assembly cons
34、ists of a cast iron barrel assembly and a detachable cast iron cylinder head assembly; the latter including integral rocker arm housings and covers completely enclosing the valve gear. The barrel assembly has a removable, centrifugally cast iron cylinder sleeve mounted in a cylinder housing and is a
35、ttached to the head by ten 12.7 mm (1/2 in) diameter bolts that extend the length of the barrel. Coolant transfer from barrel jacket to head is through ten holes drilled in the head and communicating with water passages between the cylinder sleeve and the jacket. The head is located on the upper end
36、 of the barrel by a pilot extension on the barrel. The combustion chamber is sealed by a copper ring gasket that is compressed to a predetermined thickness when the ten bolts are tightened. The combustion chamber is hemispherical in shape with the axis of the two valves intersecting at the center of
37、 the sphere. Valve seat inserts for both valves are expanded in the head. The cylinder head for both the older 5573 integral type (Figure 2) and the newer 16001 insert-type (Figure 4) will be described. On the 5573 type, two tapped holes for spark plugs are provided on opposite sides of the dome and
38、 in a plane at right angles to the plane through the valves. The included angle between the holes is 110 degrees. Standard combinations of spark plug thread diameters and reaches are shown on Table B1 in Appendix B. SAE INTERNATIONAL J2203 Revised FEB2014 Page 8 of 76 NOTE: The thermal plug used dur
39、ing spark plug rating is installed in one of the spark plug holes and contains a chromel-alumel thermocouple having a response rate of 7-1/2 s for a change from ambient room temperature to 620 C 28 C (1150 F 50 F) when dipped in a molten tin bath at 815 C 5.6 C (1500 F 10 F). The thermal plug temper
40、ature has a 4.5 s (max) travel time for the range of 18 to 860 C (0 to 1500 F). FIGURE 2 - INTEGRAL TYPE HEAD (PART # 5573) FIGURE 3 - INSERT TYPE HEAD (PART # 16001) SAE INTERNATIONAL J2203 Revised FEB2014 Page 9 of 76 The 16001 head, which is now standard, incorporates spark plug boss inserts that
41、 are mounted into the cylinder head with six 8 mm (5/16 in) studs. This spark plug insert is sealed into the combustion chamber and from the atmosphere with two 2ULQJV7KLVSURYLGHVDVHSDUDWHZDWHUMDFNHWIRUWKHVSDUNSOXJERVVIURPWKH cylinder and head water jacket. This insert makes it possible to change fr
42、om one size of spark plug to another size in a matter of minutes without disturbing the cylinder, cylinder head, or piston, which was necessary in the former 5573 head design. With the 16001 type head, the single thermal plug remains installed at all times. The cylinder sleeve is of generally unifor
43、m thickness from top to bottom, except for a small outer flange near the lower end of the sleeve. This flange engages a steel ring flange that seals the sleeve to the cylinder housing and the head by gaskets and the same ten bolts that hold the barrel assembly to the head. The inner surface of the c
44、ylinder is knurled before finish honing; and after final honing, the surface is treated with Parco-Lubrite or other similar process to improve cylinder durability. Coolant enters the lower end of the cylinder housing at the timing gear end and leaves the assembly at the top of the head between the r
45、ocker boxes. Coolant for the spark plug boss insert in the type 16001 cylinder head enters the insert jacket immediately below the insert and leaves the insert jacket directly above the insert. The cast iron rocker arms, providing an 8 mm (5/16 in) valve lift for a 6.33 mm (1/4 in) lift of the camsh
46、aft, are equipped with needle bearings operating on floating case-hardened solid steel rocker shafts, secured by cover plates bolted to the rocker box housings. Each rocker has a roller at the valve end and an adjusting screw at the push rod end. The valve gear is lubricated by pressure oil from the
47、 valve tappets, through a hole in the adjusting screw, with affords splash lubrication, supplemented by additional exhaust valve lubrication effected by projecting the push rod housing 12.7 mm (1/2 in) into the exhaust rocker box. The valves, one intake and one exhaust, have valve stem diameters and
48、 lengths considerably greater than those generally provided for the valve head diameters used. Each valve is operated by two valve springs that provide satisfactory operation up to and including 3200 rpm. 5. CRANKCASE ASSEMBLY The gear end is considered the front end of the crankcase and the flywheel end, the rear of the crankcase. The crankcase consists of an extremely rigid iron casting w
