Abstract
The utility model discloses an air-inlet heating device of a single-cylinder diesel engine, comprising an air inlet passage, wherein the air inlet passage comprises an air filter (5), an air inlet pipe (4), a cylinder cover (1) and a cylinder; air enters the cylinder through the air filter (5), the air inlet pipe (4) and the cylinder cover (1); the air-inlet heating device is characterized in that an air heating device is added on the air inlet passage of the diesel engine; and the air heating device comprises an air heater (3) arranged in the air inlet passage between the air filter (5) and the cylinder cover (1), and a power supply which supplies power to the air heater (3). In the utility model, when the diesel engine is coldly started, the air heater is connected with the power supply to carry out preheating; when the air passes by the air heater, the air is heated so as to raise the temperature of the air entering the cylinder; therefore, the diesel engine is convenient for cold starting under low temperature.
Description
Technical field
The utility model relates to a kind of diesel engine intake heating equipment, especially a kind of single cylinder diesel air-intake heating mechanism.
Background technique
Present single cylinder diesel is natural aspiration, and air passes suction tude by air-strainer, directly enter cylinder, especially winter, temperature was lower, and cool air directly enters cylinder, cause the interior temperature of cylinder lower, diesel engine starts difficult unusually under this condition.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of air-intake heating mechanism, to overcome single cylinder diesel owing to the low shortcoming that is difficult to start of intake temperature, improve the temperature and the cold start-up efficient of air inlet and firing chamber, improvement further improves the power character of diesel engine and cold starting performance by the unfavorable factor that environment caused.
For achieving the above object, the utility model provides a kind of single cylinder diesel air-intake heating mechanism, comprise the air inlet passage, described gas-entered passageway comprises air-strainer 5, suction tude 4, cylinder head 1, cylinder, air enters cylinder through air-strainer 5, suction tude 4, cylinder head 1, installed an air heater apparatus on the single cylinder diesel gas-entered passageway additional, described air heater apparatus comprises the air heater 3 that is installed in the gas-entered passageway between air-strainer 5 and the cylinder head 1 and is the power supply of air heater 3 power supplies.When diesel engine starting, earlier with power supply opening, with air heater 3 preheatings, then with diesel engine starting, air heats by air heater 3 by air-strainer 5 and suction tude 4, enters cylinder and the burning of diesel oil mixed aerosol through the air that heats by cylinder head 1.
The power supply of powering for air heater 3 is that single cylinder diesel starts power supply 2.Can for air heater 3 power supply be set separately.
The utility model has been realized when diesel engine cold start, earlier air heater 3 is connected power supply and carry out preheating, when air process air heater 3,,, be convenient to diesel engine cold machine under the lower situation of temperature and start with the air temperature that raising enters cylinder with air heating.
Description of drawings
Fig. 1 is a single cylinder diesel air-intake heating mechanism schematic representation.
Wherein: 1, cylinder head 2, startup power supply 3, air heater 4, suction tude 5, air-strainer 6, air heater mounting point second 7, air heater mounting point third
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1: single cylinder diesel of the present utility model comprises air-strainer 5, suction tude 4, cylinder head 1, parts such as cylinder, on the gas-entered passageway between air-strainer 5 and the cylinder head 1, installed an air heater 3 additional, air heater 3 is connected with startup power supply 2, energising can be generated heat, air heater 3 can be installed between suction tude 4 and the cylinder head 1, also can be installed in the air heater mounting point second 6 between suction tude 4 and the air-strainer 5, also can be installed in the air heater mounting point the third 7 of suction tude 4, no matter adopt which kind of mode, as long as just air is heated by air heater 3 smoothly can.
When diesel engine starting, will start power supply 2 earlier and open, air heater 3 preheatings, then with diesel engine starting, air heats by air heater 3 by air-strainer 5 and suction tude 4, enters cylinder and the burning of diesel oil mixed aerosol through the air that heats by cylinder head 1.
In a word, the utility model single cylinder diesel air-intake heating mechanism, on the basis of former single cylinder diesel structure, do not need big change, only install an air heater additional, and be connected with the startup power supply, the cold machine of single cylinder diesel that has promptly effectively solved long-term puzzlement people is difficult to start this difficult problem, send to Gospel for the user under cold conditions, work, solved the difficult problem that single cylinder diesel had not for many years solved always.This product is applicable to: any use single cylinder diesels such as three-wheeled motor car, low-speed truck, tractor, generator, boats and ships are as the place of power.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
