This SAE Standard establishes a vocabulary and definitions relating to the components used in fuel injection systems for compression ignition (diesel) engines. Definitions are separated into six sections by topic as follows: Section 3— Fuel Injection Pumps Section 4— Fuel Injectors Section 5— Unit Injectors Section 6— Governors Section 7— Timing Devices Section 8— High Pressure Pipes and Connections NOTE— When the word "fuel" is used in the terms listed it may be omitted providing there can be no misunderstanding.
This SAE Recommended Practice is applicable to all types of reciprocating engines including two-stroke cycle and free piston engines, and was prepared to facilitate clear understanding and promote uniformity in nomenclature. Modifying adjectives in some cases were omitted for simplicity. However, it is good practice to use adjectives when they add to clarity and understanding.
This SAE Standard was prepared by Technical Committee 1, Engine Lubrication, of SAE Fuels and Lubricants Council. The intent is to improve communications among engine manufacturers, engine users, and lubricant marketers in describing lubricant performance characteristics. The key objective is to ensure that a correct lubricant is used in each two-stroke-cycle engine.
This SAE Recommended Practice applies to the function of building reciprocating spark-ignition engines which are used in conjunction with standard and high-performance ancillary components in applications intended to achieve a minimum of 1 hp/in3. This document does not apply to rebuilt engines which may only be partially repaired with little or no machining, nor does it apply to second-hand or used engines.
Since the last edition of this report in 2013, the demand on automakers has been relentless in terms of improving fuel economy and reducing emissions, thus driving increased sales of forced induction systems. The use of pressure charging techniques has therefore expanded significantly. Recent years have seen the ascendancy of the turbocharger and its use by almost every major global manufacturer.
Off-highway CVTs A continuously variable transmission can improve the fuel efficiency of heavy-duty diesels by matching the engine's torque/speed to the applied load through the smooth torque multiplication of the transmission. Hydraulics for economics The design of a digitally controlled hydraulic fan drive from Denison Hydraulics is said to help diesel engines run leaner and cleaner. Telematics boosts productivity Advances in electronic technology enables equipment owners and operators to monitor not only usage, but location of equipment. A dumper on tracks Industrial vehicles featuring composite rubber-tracked drive systems have become increasingly popular over the past 10 years, carving out a respectable niche in many specialized industries.
