16-01-2008 Recently,
an announcement of reward by Yutong caused a great disturbance in bus and coach
industry, which was saying that 10000 Yuan was compensated if Yutong bus installed
with heat management system for engine could not save oil obviously. Many were
surprised and were curious about such a system. Now let's unveil the mystery about
how could it save oil? Everyone
knows that quality, drag coefficient of body, engine technology and driver habit
and skill are the main elements to help autos to save oil. And current auto oil
saving technologies are considered in two groups, one is to use all advanced technologies
to save oil based on existing gas motor or diesel motor, and the other is focusing
on new energy resources. And Yutong takes the advantage of the first technology
to install a set of heat management system for controlling the temperature to
save oil. What
is heat management system for engine? Researchers from Yutong post doctor workstation
found engine only can save oil when it works under optimum temperature, so they
fixed a frequency conversion air condition to control inner temperature in order
to make optimum temperature. The
heat management technology consists of two systems, including aptitude control
of cooling system and aptitude control of fan system. The cooling system keeps
temperature around 90 degrees, which is a reasonable that makes engine exerts
the biggest energy. And fan system controls heat elimination, otherwise, controlling
the frequency of fan due to it also consume energy itself when it works, so if
the fan moves reasonable and is mastered by the system, it also can save some
energy resources. 'Supposed
an auto runs 800 kilometers, it will cost 432000 Yuan a year, and if we use the
heat management system for engine, we will save 1% to 5% of total cost, equivalent
to 21600 Yuan a year, that is amazing' they said. The
system has no side effect, yet it reduces abrasion of engine, making base oil
burning completely. All above are the economy efficiency Yutong's clients will
obtain in the future, Editor:William
