flat piston造句

In the later Evolution engine, a flat piston with a redesigned head was used.
It is a four-cylinder, four-stroke air-cooled flat piston engine typically between 93-130 hp ( 69.4-97 kW ) power output.
Within the cylinder head there is ( on the left side of the engine ) a recessed combustion chamber ( with a flat piston crown ), in which the exhaust valve and the spark plug are located while the remaining area ( on the right side ) forms a squish area that is intended to swirl the fuel-air-mixture in the combustion chamber.
This was a less efficient design than the later flat piston-to compensate, common modifications included " porting " the heads, namely removing material with a die grinder to achieve a more efficient combustion chamber, and " dual plugging "-namely drilling and tapping another spark plug into each cylinder head, and firing two spark plugs at the same time for a more efficient and cleaner burn.
