Foreword

a. This recommended practice is under the joint jurisdiction of the API committee on Standardization of Rotary Drilling Equipment and the API committee on Standardization of Production Equipment.

b. The purpose of this recommended practice for installation, maintenance, and operation of internal-combustion engines is thereefold, viz.:

1. To present information of a general nature pertaining to their installation of a general nature pertaining to their installation and to emphasize installation recommendations for specific types of service, observation of which is often over looked.

2. To present maintenance check-off lists for daily, weekly, and monthly maintenance of such engines.

3. To present trouble-shooting recommendations with which the causes of most common engine troubles can be determined. This publication does not purport to be a detailed instruction manual; and, in cases where additional information is required on a particular piece of equipment, the manufacturer should be consulted.

4. To present (see Appendix A) recommendations for the elimination of fire and explosion hazards.

c. The information presented under installation and maintenance has been classified as:

1. Applicable generally to all types of internal-combustion engines in all types of service.

2. Particularly applicable to engines in drilling or semi-portable plant service.

3. Particularly applicable to engines in oil-well pumping, oil-pump, or similar service where the engines ma or may not be under daily observation. Both multiple-cylinder and single-or two-cylinder engines are considered in the latter category.

d. A related specification issued by the Division of Production, American Petroleum Institute, is:

7B-11C Specification for Internal-Combustion Engine and Unit-Type Radiator Coolers for Oil-Field Service. Covers methods of test for rating internal-combustion engines and unit-type radiator coolers for oil-field service.
