API Foreword
This standard is managed by the Production Equipment Standardization Committee of the American Petroleum Institute (API). This specification only stipulates the calibration procedures for reciprocating internal combustion engines used in oil fields, and does not provide the minimum requirements for quality or standard dimensions. Therefore, this standard does not allow the use of the American Petroleum Institute logo. The API RP7C-11F "Recommended Practice for Installation, Maintenance and Operation of Internal Combustion Engines" issued by the API's Publication Department is the relevant standard of this specification. The main contents of this standard include general recommendations and information on installation, daily, weekly and monthly maintenance inspections, and operating failures and cause analysis of various internal combustion engines used in different occasions. This standard takes effect from the date given on the cover, but can be adopted voluntarily from the date of publication. 1 Scope
Petroleum and Natural Gas Industry Standard of the People's Republic of China Specification for Internal - Combustion Reciprocating Engines for Oil Field Servkec
Specification for internal - combustion reciprocating engines for oil field servkec This standard specifies the test and calibration method for reciprocating internal combustion engines for oil field servkec. This standard is applicable to reciprocating internal combustion engines used in oil fields. SY/F 50311999
Replaces SY5031-91
The purpose of the test methods specified in this standard is to provide a unified benchmark for the comparison of similar equipment in terms of power, power requirements and recommended speed range. The test sequence does not include maintenance and durability factors, so caution should be exercised when comparing engines. The single-engine rating is only used for engines without external cooling systems. 2 Definitions
This standard adopts the following definitions.
z.1 Single engine, bare engine
An engine without other accessories except those essential for engine operation is called a single engine. Engine: All accessories required for normal operation should include ignition device, water pump, air filter, oil pump, governor, etc. 2.2 Power unit
The power unit consists of a single unit plus other equipment, such as air cooling fans, special water pumps, etc. When these equipment are included, specific data on design factors such as ambient temperature and power consumption must be given. 2.3 Maximum standard brake power maxiumstandardbrakehcsepxower At a certain speed, the maximum standard brake power refers to the maximum power that can be continuously output when converted to the standard state and under the conditions specified in the test procedure.
2.4 Maximum standard torque maxium standard torque At a given speed: refers to the torque corresponding to the maximum standard brake power at this speed. 3 Test requirements
3.1 Test engine
The design and installed parts and accessories of the test engine should be exactly the same as the engine delivered to the buyer: During the test, all the required parts should be installed in place and operate normally. 3.2 Adjustment
Before the test, the single engine or the supporting engine shall be pre-run for at least 2 hours to determine the best adjustment and to achieve the operating conditions consistent with this test standard. These conditions shall remain unchanged as much as possible during the subsequent test. During the entire test, the engine adjustment shall not be changed.
3.3 Inlet and exhaust port external connection
Inlet and exhaust port external connection See Appendix (Suggested Appendix) 3.4 Test Procedure
1) Standard condition refers to humidity of 29.4 (85T) and pressure of 99sPa (29.38:rHg) Approved by the State Administration of Petroleum and Chemical Industry on May 17, 1999 Implementation on December 1, 1999
SY:T 5031—1999
The test shall start from the lowest speed in the reverse range, and measure data in the entire speed range and continue. During the test, each data point shall be measured at least 3 times, every 5 minutes. During the observation period of 5 minutes, the speed deviation from the average speed shall not exceed ±1.25% of the average speed. The average value of the measured data shall be recorded as the test data. 3.5 Errors in engine oil, cooling water and intake air temperature During any operation period, the maximum allowable deviation of the average temperature of the outlet cooling water and engine oil is +2.8℃ (±5F). During any operation period, the temperature difference between the highest and lowest intake air temperatures shall not exceed 3.3℃ (6F). 3.6 Maximum braking power
Within the range of the lowest to the highest speed used by the oil III test, at least four speed points with roughly equal intervals shall be taken to determine the maximum braking power. When measuring the power at each point, the intake pipe vacuum and (or) pressure readings shall be recorded. See Appendix [Reminder] for the intake pipe vacuum-load curve of the self-priming internal combustion engine. 3.7 Fuel consumption
Within the range of the lowest to the highest speed recommended by the oil company, take at least four speed points with roughly equal intervals to determine the fuel consumption curve. The measurement of fuel consumption rate should be carried out in accordance with good conventional technical operation. The fuel consumption rate is expressed as follows: a) Natural engine: sl/(kw·h);
b) Diesel engine: (kw-h);
c) Gasoline engine: g/(kw-h).
The base lower calorific value of the fuel used in the test of diesel and gasoline engines is 42700kl/kgl, and the base calorific value of the fuel used in natural gas engines is 33720kl/m2 (9)5Ht1/). If the natural gas fuel does not reach the specified value, the calorific value of the fuel actually used can be recorded.

The fuel consumption rate will not be affected accordingly by changes in temperature and pressure. 4.1.3 Altitude and temperature conversion: For turbocharged engines, it is recommended to obtain these conversion data from the manufacturer. For naturally aspirated engines, the approximate values of altitude and temperature can be converted as follows: a) Above sea level, the standard braking power decreases by 3% for every 305m (1000ft) increase in altitude; b) When the ambient temperature is higher than 29.4℃ (85F), the standard braking power decreases by 1% for every 5.6℃ (10F) increase in temperature: Conversely, when the ambient temperature is lower than 29.4 (85F), the standard braking power increases by 1% for every 5.6℃ [10] decrease in temperature. 4.2 Maximum standard torque
The maximum standard torque at any given speed should be calculated from the maximum standard braking power at that speed. 5 Test report
