Tech Corner: UCE Lubrication

Tech Tips

For the UCE engines I am starting a series covering some of the design aspects. We are starting with the lubrication system for no particular reason other than the fact that we got a really cool video and slide presentation from the factory today (shown below).

Royal Enfield was the first motorcycle with a dry sump oiling system. In short this meant that the crankcase was empty and the oil is stored in a tank (internal to the engine). Pressurized oil is fed to the critical components and drops into the crank crankcase where it is picked up by a second oil pump and sent to the head. In a wet sump system like the new UCE engines the crankcase is full of oil. When the engine starts a pump picks up the oil, pumps it through a filter and then directs it to different areas under pressure. Because the clutch and transmission are all part of the engine case they all run in the same oil. The real advantage is that in the UCE we can move a lot more oil under a higher pressure than we could in the oil machines.
