Abstract
The utility model discloses an engine forced intercooler which relates to a device used for cooling the temperatures of air-feeding of an engine. The utility model comprises a casing, an insulation layer, a compressor, a cooling pipeline, a separating board, a condenser, an air-storing drier and air inlet and an engine air-feeding pipe, etc. The utility model can forcedly cool the air-feeding of the engine and leads the temperature of the air-feeding to fall to about 5 DEG C, greatly raising both air density and oxygen entering the engine cylinder for burning. Therefore, the utility model has the advantages of complete burning, reducing oil cost, enhancing the power of engine and reducing exhaust emission and pollution to air.
Description
Technical field the utility model relates to a kind of device that the intake temperature of motor is cooled off.
The background technique motor relies on in-cylinder combustion to send power.Therefore, the fuel oil and the air that enter in the cylinder are two the most basic big key elements, and both want rational allocation, and burning could be fully, make the big and fuel oil province of power.
The input quantity of fuel oil or emitted dose can be controlled and regulate, and key is air.General motor is by natural aspiration, and air imbibed quantity is subjected to the restriction of engine aspirating system resistance, only can suck the tolerance (with a large barometer, inserting the percent volume to volume of cylinder) of 70-80%, so power is difficult to improve.
Need increase pressurized machine, making the air that enters cylinder is not to rely on natural aspiration, but is forced air is pressed into or " inserting " cylinder by pressurized machine, and air quantity is increased for this reason, and the amount of fuel of injection also can correspondingly increase.Make motor not only power improve greatly, and complete because of burning, the corresponding specific fuel consumption amount that reduced, smoke intensity also makes moderate progress.
The pressurized machine of Cai Yonging is the mechanical type pressurized machine the earliest.Many employings in modern age exhaust-gas turbochargers, it utilizes the engine back pressure ripple to promote turbine, drives the impeller gas compressor of the other end, comes " drum fills " air inlet, the motor that adopts this supercharging of internal combustion engine technology is boosting type, and power ratio natural aspiration type improves 20-40%; Also significantly descend than fuel consumption rate.But enter the air of cylinder, behind exhaust-gas turbocharger, because the influence of merit by compression, intake temperature increases substantially, and temperature generally reaches about 120 ℃ during full load.The temperature height, air density obviously descends, and oxygen content is few in the air, has limited the further raising of power, " charge inter cooling " technology occurred for this reason." charge inter cooling " is with the air intake of engine cooling water or automotive front end, passes " intercooler " (being heat exchanger), the intake temperature of the motor of supercharging carried out " middle cooling ".Water cooling can be cooled to intake temperature about 90 ℃, and Luftgekuhlte rotierende can be cooled to intake temperature about 50 ℃.Its temperature is still high, and the density of air is low, and the amount of oxygen that enters cylinder is still few.
The summary of the invention the purpose of this utility model is at above-mentioned present situation, aim to provide a kind of can will be the temperature of the air inlet of the motor of supercharging or motor natural inflow be cooled to motor positive drive type intercooler about 5 ℃.
The implementation of the purpose of this utility model is that motor positive drive type intercooler includes pressurized air import 1, engine air inlet tube 2 and cooler.Cooler is made of compressor 8, the refrigerant pipe 9, the dividing plates 5 that pass in the cooler casing 3.It is a loop that refrigerant pipe 9 is connected in series with condenser 6, air storage exsiccator 7, motor 8.Insulation layer 4 is arranged in the cooler casing.
Accompanying drawing is the utility model structural representation.
With reference to accompanying drawing, the utility model adopts by compressor 8, refrigerant pipe 9, is with the cooler casing 3 of insulation layer 4 as the positive drive type cooler.Cross or enter in the cooler casing from air intlet 1 through the turbocompressor supercharging from the air that air-strainer is sent here, after the refrigerant cools in housing in the cooling pipe 9 of coiling, the air that enters engine air inlet tube 2 is only about 5 ℃, well below 90 ℃ and 50 ℃.
Because only about 5 ℃, its air density is big for the air that enters engine chamber after forcing cooling, the oxygen content height that includes is many for the oxygen of oil inflame, makes oil inflame complete, has reduced oil consumption, has improved the power of motor.
The utility model can be with the air inlet of the motor of supercharging or the temperature of motor natural inflow are cooled to about 5 ℃, improved air density greatly, that is improved enter cylinder for the burning amount of oxygen, make burning fully, reduce oil consumption, improved the power of motor, reduce toxic emission, reduce atmospheric pollution.
