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 compare to others. 

Variety of P.T.O. shaft

Meets latest emission standard in each country

AAir cleaner

Various air cleaner selection

Silent semidry type

Low dust condition 

Stationary engines such as pump and generator rice-planting machine

Silent dual type

Intermediate dust condition

Harvesting machines (binder, harvester)
Caring machines (tiller, etc.)

Semi-cyclone type

Severe dust condition

Construction machinery・・late, rammer, etc.・・br> Harvesting machines・・inder, harvester, etc.・・br> Caring machines・・arth-scattering machine・・/p>

Semidry type

Low dust condition

BIntake 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窶冱 spark spread through the mixture air. This increases the power, fuel consumption, and cleanliness exhaust emission.

CSpark 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 窶廝PR4ES.窶・/p>


The adoption of a large muffler reduces the exhaust noise. The tail screen is also adopted to MZ125 and MZ175.

EBalancer [MZ360]

MZ engine has one balancer on 360. Big capacity single cylinder engine is able to get larger vibration. In order to cure this, balancer is needed. 
Balancer shape, style, and quantity depend on each company窶冱 way of thinking.


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.


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 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.

HExhaust valve

High heat resistant SUH3 steel is used. But since exhaust valve expose to more than 700 degrees Celsius instantly, at the valve face where it meets valve seat has stellite coating. Also, whole valve surface has tufftride finish in order to increase the hardness. Together when this tufftride finish is polished, friction of surface becomes very low which makes valve to move smoother against guides.
