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. | When operating engine:: 1) The centrifugal force causes the decomp weight to open, and this movement lowers the pin. 2) The lifter is not forced to be pushed up but normally moves as the camshaft turns. 3) The exhaust valve is not opened and closed with the normal timing. | 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
