1. 156FMI-A EngineThe following
advanced techniques are used for 156FMI-A engine:
New squeezing combustion chamber technique, first
innovated in China: An airflow movement is organized through
a squeezing gap formed between piston top & combustion
chamber to increase the turbulence intensity of airflow
in piston at TDC to optimize combustion process for attaining
the objectives of reducing fuel consumption & decreasing
emissions.Single-crankshaft balanced technique: A reciprocating
inertial force of 1st order is balanced to achieve a goal
of reducing engine vibration. In combination with fuel-air
cooling technique and Secondary Air Injection System,
the following targets are hit: less than 1.4L fuel consumption
per 100km, whole engine vibration reduced more than 70%,
power & reliability increased, emissions reduced to
EURO II.
2. 152QMIA
closed oil-bathed chain driving system is innovatively
adopted to replace a traditional CTV one, with fuel consumption
being reduced 50%, emissions reduced to EURO II.
3. 150mL~250mL series engines
for tricycle
The series engines for tricycle are of horizontal/vertical
type, forced water/air-cooled, 4-stroke, and equipped
with the following specialized designs:Single-axis balance
mechanism: a reciprocating inertial force of the first
order is balanced to reduce the whole vehicle vibration
& noise.4-speed transmission: A gear drive was adopted
to obtain a higher transmitting efficiency, to raise vehicle’s
acceleration performance.Differential mechanism: It can
drive two half-shafts at the same time, and can adopt
independent suspension to raise the vehicle’s stability
and passability.Reverse gear mechanism: It provides convenience
for the users.
4. 139F series general utility
gasoline engines
The 139F series general utility gasoline engines have
an advanced structure, particular lubrication system.
Two styles of engines with displacements of 38.2mL &
45mL were respectively designed.
5. 139FDz general utility
gasoline engine
This 4-stroke engine has a displacement of 35mL, a particular
lubrication system. It can work in a range of 360 degree,
specially suitable for the special demands for chain saw,
shearing machine & military generator.
