Abstract

A diesel vehicle environmental-friendly device which uses waste heat to save energy and reduce emissions comprises an oil tank and an engine; an oil pipe is arranged on the oil tank and communicated with an oil pump on the engine; the engine is provided with an exhaust pipe; a water pump is arranged in front of the engine; a water outlet pipe and a return water pipe are arranged on the water pump; a heat blower and a heat exchanger arranged on the exhaust pipe are communicated between the water outlet pipe and the return water pipe, wherein, a heater is arranged in the oil tank; and the heater is communicated with the return water pipe and the water outlet pipe. The utility model makes use of the waste heat of the exhaust pipe to heat the diesel oil and the coolant and avoid the oil circuit of the diesel engine being plugged due to the diesel oil coagulation and crystallization at low temperature; at the same time, the utility model is conducive to full fuel combustion, which improves the engine efficiency and reduce pollutant emissions to achieve the energy-saving emission-reducing and environmental-friendly effect. The utility model makes the selection of low-grade diesel possible by the diesel vehicle under the same low temperature conditions, and has greater economic benefit.

Description

Motor Vehicle utilizes afterheat energy-saving to reduce discharging environmental protecting device

Technical field

UTILIZATION OF VESIDUAL HEAT IN technical field, especially diesel car that the utility model relates to the general vehicle discharging waste gas utilize afterheat energy-saving to reduce discharging environmental protecting device.

Background technique

Existing motor car engine is equipped with cooling system antifreeze liquid circulation means, this the device generally by water pump with liquid driven in the engine-cooling system, after outlet pipe by water pump upside or cylinder head upside enters warm-air drier, again in return pipe is got back to engine-cooling system.

At northern frore area, because of temperature low excessively, the diesel car motor can not reach optimum working temperature, and the generation oil inflame is insufficient, and output power is low, fail the phenomenons such as particulate emission increase that the fuel of perfect combustion condenses and form in the waste gas, even more serious is that diesel oil can solidify gradually, and the cured phenomenon of knot takes place, and stops up oil circuit, cause to engine oil deficiency or fuel cut-off, Motor Vehicle can't be worked.

In the real life, someone is with after the outlet pipe prolongation and turning round, from fuel tank, pass through again, diesel oil in the heated fuel oil case, its shortcoming is: Tail Pipe Temperature is restive, and Yin Gaowen and the diesel oil that makes direct bank tracheal wall are by roasting thick and rotten sometimes, when diesel oil is very few, gas also easily expands in the fuel tank, and especially outlet pipe is corroded and hole occurs, reveals thing and contacts very dangerous with fuel oil.

There also have the people that tailpipe is turned to be curved, allows waste gas directly spray to fuel tank, and its shortcoming is: the bad and surperficial accumulation of fuel tank of heating effect plays oil stain and spot, and easy-clear does not have peculiar smell, and it is dangerous to meet naked light.

Summary of the invention

The purpose of this utility model is to provide a kind of Motor Vehicle to utilize afterheat energy-saving to reduce discharging environmental protecting device, mounting heat exchanger outside outlet pipe, in fuel tank, establish heater, is that antifreeze liquid circulation means polyphone communicates with heat exchanger and heater with engine cooling, utilize the waste heat heating and anti-freezing liquid of motor engine exhaust gas pipe waste gas, use the diesel oil in the antifreeze liquid heated fuel oil case again, effectively overcome the above problems.

In order to achieve the above object, the utility model includes fuel tank and motor, there is oil pipe to communicate on the fuel tank with oil transfer pump on the motor, motor is provided with outlet pipe, motor the place ahead is provided with water pump, water pump is provided with outlet pipe and return pipe, be communicated with warm-air drier and the heat exchanger that is installed on the outlet pipe between the outlet pipe of water pump upside or cylinder head upside and return pipe, wherein, heater is installed in the fuel tank, there are water outlet and water intake in the heater two ends, are connected with outlet pipe with return pipe respectively.

In the described heater is hollow, the pipe of one or more connection, and there are water outlet and water intake in two ends, are connected with outlet pipe with return pipe respectively.

Described heater is apart from the fuel tank base plate more than 20 millimeters and be lower than sixth fuel tank height.

The utility model has following advantage:

1, the utility model utilizes the waste heat of outlet pipe, do not need the additional dedicated heating plant, heated the temperature of diesel oil and antifreeze liquid, avoided diesel car to solidify because of diesel oil at low-temperature, the cured phenomenon of knot taking place and stop up the oil circuit problem, be beneficial to fuel oil again simultaneously and fully burn, improves engine efficiency, reduce pollutant emission, reach the energy-saving, emission-reducing, environment friendly effect.

2, the utility model can reduce the temperature of outlet pipe, helps the work of engine exhaust stroke, improves the power and stability of motor.

3, the utility model makes diesel car select for use low trade mark diesel oil to become possibility under equal cryogenic conditions, has promptly improved economic benefit, reaches energy-saving effect again.

4, the utility model principle is simple, is easy to realize, has a extensive future.
