EOS Quattro
The EOS QUATTRO is the 2nd generation of the EOS 4-stroke engine range. It delivers smooth and progressive power, a low noise level and very low fuel consumption. The EOS QUATTRO engine is a lightweight single-cylinder, 4-stroke, 4-valve engine with a decompression start system.
The decompression system releases 70% of the compression during the starting sequence. This makes the engine easy to start. As soon as the engine starts, the decompression system switches off automatically. EOS QUATTRO is a 2-piece, completely CNC-milled crankcase engine made of aluminium. The engine has a displacement of 276 cm³ and has 4 valves driven by an overhead camshaft with chain drive. The lubrication system is driven by an oil pump and provides constant oil pressure regardless of oil temperature or engine speed.
Our EOS QUATTRO cylinder is NICASIL coated and precision machined for increased wear resistance. The crankshaft is fitted with oversized bearings, specially balanced to ensure long life. The propeller drive of the engine is via a clutch further with a Poly-V 16 ribbed belt.
The EOS QUATTRO is suitable for foot-launch PPG, Trikes, Microlights and Delta Trike
