Specific embodiment
The utility model is described in detail below with reference to specific embodiment shown in the drawings.But these embodiment party
Formula is not intended to limit the utility model, structure that those skilled in the art are made according to these embodiments, method or
Transformation functionally is all contained in the protection scope of the utility model.
Gasoline engine 100 shown in referring to Fig.1 is a preferred embodiment of the utility model, with the gasoline engine 100
For be illustrated.The gasoline engine 100 includes body, is arranged in the intracorporal cylinder 16 of machine, is arranged in cylinder 16 and reciprocally transports
The fuel tank of crankshaft 162, the electric starter 17 and storage gasoline that are arranged on body that dynamic piston 161 and piston 161 interlock
18,16 side of cylinder is set and is equipped with the carburetor 13 of inlet channel 11, the air cleaner of 13 side of carburetor is set
12, and the muffler 15 of 16 other side of cylinder is set.In 100 starting stage of gasoline engine, air after air cleaner 12,
Air-fuel mixture is mixed to form with gasoline in carburetor 13, air-fuel mixture enters by inlet channel 11
Into cylinder 16, air-fuel mixture burns in the combustion chamber of cylinder 16 pushes piston 161 to move.
Air cleaner 12 in present embodiment includes ceramic heating flake 123, be can be used in low temperature cold state
Under, the gas entered in cylinder 16 is heated in advance.Specifically, as shown in figure 3, air cleaner 12 includes shell 121
With pedestal 124, air cleaner 12 is interior to be equipped with cricoid filtering sponge 122.The outer peripheral edge of shell 121 be provided with lattice-shaped into
Port 1211, external air enter the inner cavity of air cleaner 12 after passing through filtering sponge 122 from air inlet 1211.
As shown in Figure 3 and Figure 4, filtering sponge 122 is substantially in that the cyclic structure of " mouth " font specifically filters sponge
122 through-hole 122d, the inner peripheral surface 122a towards through-hole 122d, the outer peripheral surface 122b opposite with inner peripheral surface 122a with middle part,
Medial surface and the lateral surface 122c opposite with medial surface close to charge air flow downstream.Between medial surface and lateral surface 122c
Distance definition is the width a for filtering sponge 122, and the distance between outer peripheral surface 122b and inner peripheral surface 122a are defined as filtering sponge
122 thickness b.Filtering sponge 122 adapts to the Internal periphery of shell 121, i.e. filtering sponge 122 can be embedded in along the direction thickness b
The rigging position of corresponding shell 121 filters sponge 122 in the width direction without departing from the outer profile range of shell 121.
The part within the outer peripheral surface 122b of filtering sponge 122 is arranged in ceramic frame heating sheet 123.Specifically, ceramic heating flake 123 had been both
It can be set between the outer peripheral surface 122b and inner peripheral surface 122a of filtering sponge 122, also can be set and filtering other than sponge 122
And at the center of air cleaner 12.If ceramic heating flake 123 be arranged in filtering sponge 122 outer peripheral surface 122b with
Between inner peripheral surface 122a, slot 1221 can be set on the medial surface or lateral surface 122c of filtering sponge 122, and slot 1221 is along mistake
The width direction for filtering sponge 122 extends towards another side.In this embodiment, on the medial surface for filtering sponge 122
It is provided with slot 1221, slot 1221 is recessed from the direction of the outside side 122c of medial surface.Ceramic heating flake 123 at least partly embeds
In slot 1221.Ceramic heating flake 123 is equally also substantially in the ring structure of " mouth " font.Further, it filters in order to prevent
Sponge 122 is ignited, and needs the filtering sponge 122 that burning point is high, and specifically, the burning point of filtering sponge 122 is not less than 120 DEG C, this
Polyurethane (PU) sponge is used in specific embodiment.Under low temperature cold state, outside air was passed through by air inlet 1211
Enter the inner cavity of air cleaner 12 after filter sponge 122, ceramic heating flake 123 adds the air by filtering sponge 122
Heat.Since the air velocity to be heated in air filter is slow, and the target temperature heated is low (normally no higher than 25 DEG C), therefore heats
Target temperature the burning point of filtering sponge 122 is much not achieved, so guaranteeing there is no the risk that is ignited of filtering sponge 122
The safety and feasibility of this scheme.Heated air is mixed with gasoline, can be effectively prevented from into cylinder 16
Gasoline in interior air-fuel mixture condenses on cylinder inner wall, ensure that in cylinder gasoline in air-fuel mixture
Concentration, make it easier to be lighted, gasoline engine 100 be easier started.
The following detailed description of starting process of the gasoline engine 100 under low temperature cold state.As shown in Figure 1 and Figure 2, initial
Under state, electric starter 17 is started after closing choke, electric starter 17 is moved with dynamic crankshaft 162, and then with piston 161
It is moved in cylinder.For four-stroke engine provided in this embodiment, in induction stroke, outside air is by air inlet 1211
Outer peripheral surface 122b along filtering sponge 122 enters air cleaner after filtering sponge 122 to the direction of inner peripheral surface 122a
In 122 inner cavity, air is heated by ceramic heating flake 123.Specifically, as shown in figure 5, ceramic heating flake 123 is arranged in slot
1221 middle position, there are gaps with slot 1221 inside and outside ceramic heating flake 123, and ceramic heating flake 123 is
Reticular structure has multiple leak holes, and outside air enters in slot 1221 from outer peripheral surface 122b, and ceramic in slot 1221
Heating sheet 123 heats, and heated air passes through inner peripheral surface 122a again and enters in the inner cavity of air cleaner 122, air
Trend is as illustrated by arrows 5.Then, heated air enters in carburetor 13, with gasoline be mixed to form have compared with
The air-fuel mixture of high-temperature, air-fuel mixture are entered in cylinder 16 by inlet channel 11.Due to air-
Air in fuel oil mixture is heated in advance, therefore is not in wherein after air-fuel mixture enters cylinder 16
Gasoline largely condense on 16 inner wall of cylinder, would not also cause the gasoline in the air-fuel mixture in cylinder 16 dense
Degree decline makes air-fuel mixture be easier to be lighted, and gasoline engine 100 is easier to start under low temperature cold state.
