MZ300

Description

Yamaha engines have met international standards for fuel emissions. our high-tech engines feature low oil cut off levers, a variety of air cleaner / air intake variations suitable to engine application, hemispherical combustion chambers and valve angle set to proportion where economic power vs fuel consumption is of most importance. ||| Engine type: Valve configuration: OHV, Shaft type: Horizontal, Stroke: 4 stroke | General: Ignition System: T.C.I, Starter type: Recoil, L*W*H: 362 × 426 × 427 mm, Dry Weight: 26 kg, Fuel Tank Capacity: 5.8 Litres, Fuel Type: Gasoline, Oil Capacity: 1.0 Litres, Lubrication type: Splash, Auto Low oil cut off: x | Engine Specs: Displacement: 296 cm3, Net rated output (kW/hp): 7.5 kW, Net rated (hp): 10hp, Maximum Power (ps): 7.0 kW (9.5 PS) / 3600 rpm, Maximum Torque: 20.3 N m (2.0 kgf m) / 2400 rpm, P.T.O Shaft options: A2B Option : 25.4 mm (1’inch) Horizontal shaft, parallel keyed. E2 Option: male threaded. K2-50 Option: Taper shaft option. BR2B: 20mm shaft, parallel/keyed with 2:1 reduction engine at 3600 rpm., 2:1 Geared reduction options: -, Airfilter type: Silent Dual or Semi-Cyclone options., Cooling: Naturally aspirated ||| Clean P.T.O. face: The mounting face of the P.T.O. side, MZ engine is almost flat against applications. This will make customer easier to apply their product fit against our engine compared to others.
Variety of P.T.O. shaft, Meets latest emission standard in each country | Intake manifold: MZ engine mixture air goes into the cylinder having swirl. Mixture air needs to go into the cylinder uniformly. Also during compression and combustion, having swirl will increase the speed of plug spark spread through the mixture air. This increases the power, fuel consumption, and cleanliness exhaust emission. | Spark plug: Register plug for noise reduction. Standard equipped a resistance type SPARK PLUG The mounting face of the P.T.O. side, MZ engine is PR4ES. | Muffler: The adoption of a large muffler reduces the exhaust noise. | Decompression: When starting the engine, the compression pressure is reduced by forcing the exhaust valve to open, thus facilitating the start operation. | When stopping/starting the engine:: 1) The decomp weight pushes up the pin to push the lifter.
2) The exhaust valve is not opened or closed as the camshaft turns but forced to open. | Sleeve: Spiny sleeve is used. Since the engine block is aluminum, cast iron sleeve is fitted for more durability and less worn out. This sleeve is called spiny sleeve that has special shape. When aluminum and steel expands by heat, their expand rate is different(aluminum is more than steel). This difference will create air pockets but with spiny sleeve is keeps this level is very small. Spiny sleeve is shaped liked jigsaw puzzle and even if aluminum and steel expands in different ratio, the air pocket will not occur largely. This will help to radiate the engine inside heat transfer to sleeve, block, and fin and keep the engine temperature in more idealistic figure.
