9.3) Lubrication system
9.3.1) Lubrication
Generally the engines are designed to run on a mixture of gasoline
and 2 % oil.
For preparation of fuel-oil mixture refer to section 10.2.2.
9.3.2) Oil injection lubrication of ROTAX 503 UL DCDI, 582 UL DCDI
and 582 UL DCDI mod. 99
The oil pump (1) driven by the crankshaft (2) via the pump gear
(3) (or via cross shaft at 582 UL DCDI and 582 UL DCDI mod.99)
feeds the engine with fresh oil. The oil pump is a piston type pump
with metering system. Via diffuser jets in the intake cover
respectively intake socket each cylinder is supplied with exactly
proportioned quantity of Super two-stroke oil. The oil quantity is
defined by the engine r.p.m and the oil pump lever position. This
lever is actuated via a Bowden cable connected to the throttle
cable. The oil comes to the pump from an oil tank by gravity.
▲ WARNING: In case of fresh oil lubrication, the carburetors
are fed with pure gasoline (no oil/gasoline
mixture).
◆ NOTE: Figure shows version 503. Oil pump is driven by
pump gear.
