Abstract

A cold starting boosting air filter belongs to the field of an engine starting technology. In order to provide help for the cold starting of an engine in winter and meet the demands in different environments, the invention designs two schemes; specifically, the scheme I is that the air filter is mainly divided into a filter chamber and a hot air chamber, a filter core is arranged in the filter chamber, the left side of the filter core is directly communicated with an air inlet, the right side of the filter core is connected with an air path, a heater is arranged on the air path, and the hot air chamber is arranged on the heater and is communicated with an air outlet connected with the air inlet of the engine; the second scheme is that the air filter is divided into left and right parts, the left side is the filter chamber, the right side is a heating chamber, the filter chamber at the left side is directly communicated with the air inlet, the heating chamber at the right side is provided with the heater and is communicated with the air outlet connected with the air inlet of the engine, and the benefits of the second scheme are that air enters the air filter from the air inlet and is sucked into a cylinder of the engine after being heated by the heater, so the temperature of the air compressed in the cylinder is improved and help is provided for the cold starting of the engine.

Description

Help the cold air-strainer that opens

Technical field

A field of engine start technology.

Background technique

In winter, the cold starting in motor morning is the most headachy something, particularly the northern area in and the world of ice and snow not good enough in vehicle condition.Temperature drops to the severe cold of subzero twenty or thirty degree, and a lot of people usually carry on a shoulder pole because of engine start in morning difficulty the work that missed.Therefore, motor cold start-up in winter difficulty always difficulty a lot of drivers and other internal-combustion engine user.For ato unit quickly above-mentioned in the situation that, people have invented starting power supply.The use of starting power supply can be actuating motor sufficient power supply is provided, and the dependence to battery while reducing engine start can turn round with long period and larger power actuating motor, for ato unit is created better condition.Even but like this, the factor of the difficulty in starting that low temperature causes is not eliminated or is improved.The startup of motor is still very painstaking, and this does the disadvantage that also has it, and for example it can greatly increase the wearing and tearing of actuating motor and produces effects and not bery desirable; The reason of motor cold start-up in winter difficulty is many-sided and is complicated, and technically, people are also for it has taked a lot of measures.But have one by people, to be ignored, never people proposed the factor of solution always.When that is exactly winter, the air temperature that cylinder sucks is too low, causes in cylinder, and the high-pressure air being obtained after piston compression or the temperature of mixed gas are too low equally, does not reach ignition condition and causes difficulty in starting.Why easily start that to have a chief reason be that temperature is higher summer, the high-pressure air that the air of higher temperature or mixed gas obtain after compression in cylinder or the temperature of mixed gas are much higher during than winter, more easily meet ignition condition, so relatively easily starting.Obviously, the temperature of the high-pressure air in cylinder or mixed gas is directly connected to whether meeting of ignition condition.So the air that cylinder sucks or the temperature of mixed gas are too low is a very important reason that causes starting difficulty.Yet in the prior art not for this factor technological scheme.

Summary of the invention

In order to offer help to the cold start-up of motor when the winter, the measure that the present invention takes is in air-strainer, air to be heated, to improve the intake temperature of motor.The technological scheme that can meet this requirement is a lot, and for cater to the needs of varying environment simultaneously, the present invention has designed two cover technological schemes.Their concrete structure is: one. heat-storaging air-strainer, is mainly divided into filter chamber 2 and hot gas chamber 4 air-strainer.Filter core 3 is housed in filter chamber 2, the straight-through suction port 1 in the left side of filter core 3, filter core 3 the right are communicated with air flue 7.Air flue 7 is heater 5 above, and heater 5 is hot gas chamber 4 above.Hot gas chamber 4 is communicated with air outlet 6, air outlet 6 connecting engine suction ports, as shown in Figure 1; Two. Instant heating type air-strainer, filter core 3 is divided into left and right two parts air-strainer, and the left side is that filter chamber 2 and the right are heating chamber 8, the straight-through suction port 1 in filter chamber, the left side 2, the right heating chamber 8 is equipped with heater 5 and is communicated with air outlet 6, air outlet 6 connecting engine suction ports, as shown in Figure 2.

The benefit of doing is like this that air enters air-strainer from suction port 1, after filter core 3 filters, by heater 5, is heated, and is then inhaled in the cylinder of motor.Because air is heated before entering cylinder, the temperature after it makes air compressed in cylinder improves greatly, has improved the condition of igniting, for cold start engine has brought rare help.

embodiment

Help cold start-up air-strainer to be mainly divided into heat-storaging and Instant heating type two kinds.Heat-storaging is applicable to the wild environment with battery powered small-power power supply, the Instant heating type indoor environment that is applicable to having large power supply power supply, and they respectively have advantage.Heat-storaging is exactly with small-power power supplying and heating, by hot gas chamber 4 hot gas store for when starting once.Due to its less demanding to power supply, so be particularly suitable for battery powered wild environment; Instant heating type dependence electric network source is with high-power power supplying and heating, thus it need not wait for, while can generate heat, start, reduce burden and injury to starting battery.Simultaneously because power supply is sufficient, number of times that can heat supply and time are unrestricted etc.

These two kinds of forms help the cold structure that opens air-strainer respectively: one. heat-storaging air-strainer, is mainly divided into filter chamber 2 and hot gas chamber 4 air-strainer.Filter core 3 is housed in filter chamber 2, the straight-through suction port 1 in the left side of filter core 3, the right of filter core 3 is communicated with air flue 7.Air flue 7 is heater 5 above, and heater 5 is hot gas chamber 4 above.Hot gas chamber 4 is communicated with air outlet 6, air outlet 6 connecting engine suction ports, as shown in Figure 1; Two. Instant heating type air-strainer, filter core 3 is divided into left and right two parts air-strainer, and the left side is that filter chamber 2 and the right are heating chamber 8, the straight-through suction port 1 in filter chamber, the left side 2, the right heating chamber 8 is equipped with heater 5 and is communicated with air outlet 6, air outlet 6 connecting engine suction ports, as shown in Figure 2.

Heat-storaging helps the cold working principle that opens air-strainer to be: air enters air-strainer from suction port 1, after filter core 3 filters, enters air flue 7.Before engine start, first connect the power supply of air-strainer internal heat generation device 5, when heater 5 energising, it can heat the air in air-strainer.The air of the inside is heated rear rising and is stored in hot gas chamber 4.When engine start, by the hot air after heater 5 heating, be inhaled into the cylinder of motor.Because air is at this moment heated to higher temperature, it,, by pressurized air in cylinder or the temperature of mixed gas are improved greatly, has improved the condition of igniting, for cold start engine has brought rare help.

Instant heating typely help the cold working principle that opens air-strainer to be: air enters air-strainer from suction port 1, after filter core 3 filters, enter heating chamber 8.The power supply of connecting air-strainer internal heat generation device 5 in ato unit, heats immediately to the air in air-strainer.At this moment, by the hot air after heater 5 heating, be inhaled in the cylinder of motor.Because air is at this moment heated to higher temperature, it,, by pressurized air in cylinder or the temperature of mixed gas are improved greatly, has improved the condition of igniting, for cold start engine has brought rare help.
