Starting aids, such as glow plugs, are usually installed on _______________.

AI Explanation
The correct answer is D) small diesel engines with electric motor starters. Starting aids, such as glow plugs, are usually installed on small diesel engines with electric motor starters to assist in starting the engine, especially in cold weather conditions. Glow plugs help heat the air in the engine's cylinders, making it easier for the engine to start and run smoothly. This feature is typically found on smaller diesel engines, rather than larger, direct drive diesel engines (option A), diesel engines designed to burn residual fuels (option B), or medium-speed, four-stroke cycle diesel engines (option C).
