Abstract

The utility model relates to a high-speed starter for diesel engine in cold condition, comprising a crust, a wind door board, a wind door pivot, as well as a crank body. The main features is that the wind door pivot is the pivot platform structure to guarantee the locating credibility. It adopts the porous throttle in order to receive the goal to start easily and not effect the horsepower. Simultaneously the utility model is also has the advantages such as simple structure, easy adjustment, convenient function, labor saving in start, etc. So the utility model is an ideal starting aid welcomed deeply by the large of drivers.

Description

Low-temp. high-speed starter for diesel engine

The utility model relates to the device of diesel engine quick starting under the low temperature situation.

At present, some diesel engines of China exist in the problem of starting difficulty under the cryogenic conditions, most of tractor driver is that employing adds boiling water, the roasting car of naked light, air inlet is lighted a fire or pilots engine with ways such as primer fluids, do time-consuming like this, waste energy, befouling environment, labor intensity is big, easy breaking out of fire accident, Technological Economy is poor.Though at present 190 diesel engine air inlet restriction starters are arranged, it is adapted to 190 types, vertical or horizontal S195 serial diesel engine is inapplicable, this starter has certain influence to power simultaneously, and exist the air door location unreliable, easy to wear, influence problems such as starting performance.

The purpose of this utility model is exactly a kind of device that makes diesel engine be easy to start that provides at above-mentioned situation, not only make diesel engine starting reliably not influence power, but also be applicable to the starting of S195 diesel engine, thereby solved the problem of diesel engine in cold-starting.

Solution of the present utility model is to form and combustion principle according to the diesel engine mixed gas, on the diesel engine of different firing chambers and compression ratio, suitably adjust the ratio of its inflammable mixture, improve the concentration and the temperature of mixed gas in the cylinder, thereby reach the purpose that is easy to starting.

Detailed content of the present utility model is described below referring to accompanying drawing:

Diesel engine low temperature quick start of the present utility model comprises housing (1), air door plate (2), axle of the air door (3) and handle body (5), between handle body (5) and handle cover (8), spring (7) is housed, be connected by locating stud (4) between handle body (5) and the housing (1), as shown in Figure 1, feature of the present utility model is that axle of the air door (3) is the pillow block structure, guarantee that so not only the location is reliable, can not cause air door plate to move, deflection, thereby change air inflow, influence starting performance, simultaneously starting power is also had certain influence nor easy to wear.Air door plate of the present utility model has a plurality of throttle orifices on (2), between the edge of air door plate (2) and the housing (1) certain interval is arranged, since time of forming in cylinder of diesel engine mixed gas is short and compression ratio different with installation form about etc. characteristics, the utility model adopts the porous throttling and guarantees the air door plate edge and the certain uniform gap of housing maintenance, its purpose is in improving cylinder temperature and the mixture strength and the uniformity, also guarantee the required air inflow of fuel oil perfect combustion under nominal situation, thereby starting does not influence power easily.Four throttle orifices (9) are arranged on air door plate of the present utility model, and the aperture is 2.5 millimeters, and the gap the best between air door plate edge and the housing (1) is 0.35 millimeter.In the utility model, in order to satisfy S195 type, 195A diesel engine air inlet base pitch-row difference, the mounting hole (11) on the housing (1) is a waist garden shape, thereby satisfies the requirement of installing and using of this type of type.

As the S195 diesel engine being loaded onto the test of this starter:

Vehicle (number) 18 018

The open and close of starter working state

Maximum no load governed speed (rev/min) 2,105 2042

Minimum stable engine speed (rev/min) 468 415

Throttle position immobilizes

The stabile test rotating speed (rev/min) 1,920 1904

Measured power (horsepower) 11.4 11.5

Test fuel consumption (gram) 1.06 1.03

Test time (second) 1.00 0.95

Oil consumption rate (gram/horsepower-hour) 202.3 194.5

The diesel engine low temperature quick start that the utility model provides proves from above-mentioned test result: can obviously improve starting performance, it is more remarkable that its effect is installed on old machine, and can reduce oil consumption, do not influence power, thereby improved the service behaviour of motor, it is a kind of more satisfactory starting aid, simultaneously it has simple in structurely, installs easily, and is easy to operate, advantage such as laborsaving is subjected to numerous tractor drivers' welcome deeply during starting.

Description of drawings:

Accompanying drawing is represented structural representation of the present utility model.(1) housing wherein; (2) air door plate; (3) axle of the air door; (4) locating stud; (5) handle body; (6) lateral pin; (7) spring; (8) handle cover; (9) rivet; (10) throttle orifice; (11) mounting hole.

According to embodiment shown in the drawings, adopt technologies such as processes such as cast iron, steel are cast, dig, milled, car, punching press to assemble for S195 diesel engine low temperature quick start, be difficult for because of higher temperature and sharp pounding deformed damaged, axle of the air door adopts steel pin (6), (4) location, reliable performance, starting and in servicely can not open or close air door automatically, thereby influence starting and proper functioning, axle of the air door adopts up and down movingly, low pad is adopted in joint, housing two ends, seal sternlyer, do not influence starting performance and the service behaviour and the air filtering effect of locomotive.Starter boundary dimension is 92 * 83 * 20(millimeter), be installed between cylinder cover for diesel engine intake duct plane and the air-strainer inlet flange, connect with N8 * 40 stud bolts.Close chock plate during starting, being about to handle mentions and makes locating stud and housing disengaging half-twist, put down handle then, locating stud enters in the hole on the housing, this moment air just four apertures on gap between air door plate edge and the housing and the air door plate enter in the cylinder, because the air inlet sectional area ratio dwindled originally greatly, the air quantity that enters in the cylinder reduces, thereby the pressure ratio in the cylinder slightly reduced originally, air displacement reduces, improved the temperature in the cylinder, under the constant situation of oil mass, the concentration of inflammable mixture increases in spraying into cylinder, and temperature improves, simultaneously, because inlet stream speed is accelerated, the friction aggravation between the air molecule, eddy current is strengthened, further improved the condition that mixed gas forms, thereby reached the laborsaving purpose that is easy to starting, simultaneously, because the effect of damming, the air that enters in the cylinder reduces, the proportions of ingredients of inflammable mixture is suitably adjusted, and can suitably reduce fuel delivery, does not influence starting performance, meanwhile, because the starting time is short, starting speed reduces, under the constant condition of unit time fuel delivery, thereby can reduce the starting oil mass, reach the purpose of fuel-economizing.
