The invention discloses an automobile energy-saving and efficiency-increasing
system, comprising an ECU
control circuit, a sensor, an expander ECU
control circuit, an engine air-entering and a pressure-increasing compensating mechanism, an engine liquid atomization compensating mechanism, an automatic intrusive
starter, a transient power compensating mechanism and an
electric machinery, wherein, the engine air-entering and pressure-increasing compensating mechanism, the engine liquid atomization compensating mechanism, the automatic intrusive
starter, the transient power compensating mechanism and the
electric machinery are controlled by the expander ECU
control circuit. The invention can improve transient required ratio precision between air and
fuel oil, transient transporting proportioning precision and the power of original automobile engine; the invention has the advantages of
fast start and acceleration; the engine liquid atomization compensating mechanism can be used for increasing the expansion pressure of a
combustion chamber after combusting, thereby the
kinetic energy of the engine can be correspondingly improved and large amount of
fuel oil can be saved when the engine outputs equivalent power; and the invention not only improves
engine power but also reduces
oil consumption, which is excellently characterized in that the purification degree of
exhaust emission is high and has the rate of economizing
gasoline which is more than 10%. The power is improved by more than 5% and the
environmental protection function is superior to the original state-IV Europe.
