Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the heat exchanger passing into the lubricant oil of motor exhaust and engine lubricating oil circuit is set, thus motor exhaust and engine lubricating oil can be utilized to carry out heat exchange, engine lubricating oil can be made to heat up, the viscosity of engine lubricating oil rises with temperature and reduces, suitable engine lubrication oil temperature can reduce the friction between lubricant oil inside and motor parts, thus reduces fuel consume; Meanwhile, can also guarantee that lubrication is in the optimum state, to reduce the wearing and tearing of motor, improve engine life.
2, the interior heat-exchanging piece of grease channel of establishing is arranged in exhaust gas channel, tail gas can be made to carry out heat exchange by the omnibearing lubricant oil with flowing through in heat-exchanging piece, thus fully effectively utilize the waste heat of tail gas.
3, multiple heat exchange unit is set, to shunt lubricant oil, can realizes heating faster.
4, heat exchange unit is enclosed by two heat exchanging plate, is convenient to manufacturing, long narrow water conservancy diversion chamber lubricant oil can be made to obtain evenly heating.
5, heat exchanging plate arranges the roundabout curved raised portion of band groove, can increase heat exchange area.
6, another heat exchanging plate arranges the reentrant part corresponding to ridge, and restriction tail gas passes through from the gap between ridge and reentrant part, extends the tail gas currency, to utilize the heat energy of tail gas more fully.
7, heat exchange housing arranges tail gas bypass and flow control valve, can improve the level of integration of device, reduces assembly space and assembly process.
8, use tail gas heating lubricant oil, greatly can shorten warm-up times, thus reduce the discharge of CO and HC, effectively reduce the discharge of urban pollutant.
