Question

Two small engine technicians are disassembling the engine shown in Figure A-9. After observing the engine components, both technicians say that this engine has a splash-type lubrication system. Technician A says that the engine uses a dipper that's attached to the connecting rod to splash oil from the crankcase onto its components. Technician B says that engine uses a slinger that's driven by the timing gears to splash oil onto its components. Which of the following statements is correct?

Answer 1

A splash-type lubrication system uses what the Technician A says : that the engine uses a dipper that's attached to the connecting rod to splash oil from the crankcase onto its components. In the engine, dippers on the connecting-rod bearing caps enter the oil pan with each revolution to produce the oil splash. A passage is drilled in each rod from the dipper to the bearing to ensure lubrication.
