Design Air-cooed singe-cyinder 4-stroke Diese engine. Vertica cyinder. Light aoy diecast cyinder crankcase. Light aoy cyinder head. Forged crankshaft Light aoy piston for ow free forces of gravity. Labrication by pressurised circuation of oi, fine screen fitering in main fow. Vave contro by rocker, push-rods and tappets. Characteristics Engine Type Dimensions (mm) Länge Breite Höhe Direct injection. Compression :22. Good cod start performance. Fue orientated mixture preparation. Resut: exceent exhaust quaity. Speed reguation by spring-oaded governor. Proportionaity < 5% at / r.p.m. The contro cover houses the governor, the entire vave drive, the injector pump drive and the automatic decompression system and oi pump. Oi drain on both (narrow) sides of the engine. This gives free access of at east one drain position for amost a instaations. Dry air fiter with paper cartridge and integrated pre-ceaner. Cooing fan and AC generator incorporated in the fywhee (not sensitive to dust). 4 seperate engine feet permit mounting on uneven foundations. Differences of eve of up to mm can be corrected. Exhaust outet fexibe as regards both position and direction of exit

During your first instaation pease make sure that easy accessibiity of service and operating points is assured. The easier the accessibiity is, the sooner and more conscientous the engine wi be maintened. Pease convince yoursef personay that a serve and operation points are easiy accessibe before deivering your machine to the customer.

LED-dispay are mounted to the engine or wi be deivered upon request as swithboard-instruments with cabe (2m) oose. The engine is started and controed from this instrument box. Instrument box and cabe harness are part of the additiona equipment and suppied according to the number of eectrica safety features which are required. If the engine has to be started at temperatures beow - 5 C, engine must be fitted with a pre-heating system (gow pug) (additiona equipment). Further additiona equipments incude automatic start and stop, remote contro etc. Pease ask for drawings and wirings diagrams.
