MAN-88 – UK
GENERAL DESCRIPTION OF ENGINE
This engine is for propaedeutic series and for very young drivers and has been specifically
designed and developed for powering of kart, either for racing purposes and hobby, but
always on closed tracks.
During the design phase has been inspired to the technical solutions already adopted for
high-performance engines kart, to its simplicity of installation and use, related to a
parsimonious maintenance, in order to ensure the maximum durability and reliability of the
components, subject to compliance with the operational limits.
The engine is single-cylinder and uses the principle OTTO two stroke.
The cylinder and the crankcase are made in aluminium alloy.
The pressed-in lineris made of centrifuged cast iron, fully machined from a solid to ensure
the best stability and homogeneity of sliding.
The head is separated from cylinder and is secured to the cylinder with through studs.
The crankshaft is built and supported by ball bearings. It’s made of alloy steel, hardened and
tempered, as well as the connecting rod (which also undergoes a surface treatment of
copper plating), which rotates on roller-bearings on both sides.
The ignition system is of analogical type with discharge capacity, is powered by a flywheel
and a coil whose functions are to generate the spark energy required for a proper
management of goodwill, provide the references phase by a pick-up integrated.
The plant comprises a rotor-stator, a high voltage coil, which allow the control of the
advance.
The engine is equipped with a pull starter.
The engine is also equipped with a centrifugal dry clutch with low maintenance with
incorporated sprocket.
The carburettor type is a diaphragm (series Tillotson HS) includes an integrated fuel pump
and filter with the air manifold also.
The exhaust system, including in the supply, is already tuned and optimized to ensure the
best possible performance.
