Abstract
For a diesel engine for psychro-environment, relate to power engine technical field.Outlet pipe end is provided with thermal energy converter one, is provided with thermal energy converter two in oil sump, and thermal energy converter one, thermal energy converter two are connected with water storage box respectively; Emission by exhaust pipe high-temperature tail gas out adds hot cooling water, and the cooling water after heating collected by water storage box, during engine cold-start, and the high-temperature-hot-water circulating-heating fuel oil in water storage box and lubricant oil; Suction tude is provided with electric heating wire; During engine cold-start, storage battery heating electric heating wire and cool air, electric heating wire raises the intake temperature of suction tude.The diesel engine that the utility model can realize under psychro-environment starts automatically, and reduce the wearing and tearing of motor, rational in infrastructure, automaticity is high, stable performance.
Description
Technical field
The utility model relates to power engine technical field, specifically a kind of diesel engine system used under psychro-environment.
Background technique
As everyone knows, diesel engine belongs to compression ignition internal combustion engine, the fuel diesel that diesel engine uses, diesel oil is sprayed into cylinder with very high pressure being compressed to budc, inflammable mixture is formed with the pressurized air in cylinder, then utilize compression high temperature at the end, make mixed gas ignition voluntarily.Due to formation and the ignition of diesel oil mixed gas, all require that the air entering cylinder has higher temperature and pressure after being compressed.Therefore, when the temperature of the surroundings is low, there is the problem of engine start difficulty in diesel engine unit, and when ambient temperature is low especially (-30 ~ 40 DEG C), if do not take assistant starting measure, motor even cannot start.
Automatic priming technique at low ambient conditions, especially one of the technical barrier of industry.At present, diesel engine unit starts at low ambient temperatures, except usually using low temperature storage battery, subzero engine oil and low temperature fuel oil, also needs to take some cold-starting ancillary methods.But operating cost is higher, be difficult to spread.
Summary of the invention
For overcoming the deficiency of diesel engine automatic priming technique at low ambient conditions, goal of the invention of the present utility model is to provide a kind of diesel engine for psychro-environment, comprehensive solution motor is under psychro-environment, and because intake temperature is lower, cooling water temperature is low, organism temperature is low, fuel oil temperature is low, under storage battery cryogenic conditions, electricity shortage etc. causes the problem that cannot normally start.
For achieving the above object, the end of the outlet pipe of the utility model diesel engine is provided with thermal energy converter one, is provided with thermal energy converter two in oil sump, and thermal energy converter one, thermal energy converter two are connected with water storage box respectively; Emission by exhaust pipe high-temperature tail gas out adds hot cooling water, and the cooling water after heating collected by water storage box, during engine cold-start, and the high-temperature-hot-water circulating-heating fuel oil in water storage box and lubricant oil.
The suction tude of described diesel engine is provided with electric heating wire; During engine cold-start, storage battery heating electric heating wire and cool air, electric heating wire raises the intake temperature of suction tude.
Compared with prior art, the diesel engine that can realize under psychro-environment starts the utility model automatically, and reduce the wearing and tearing of motor, rational in infrastructure, automaticity is high, stable performance.
Accompanying drawing explanation
Fig. 1 is structural representation sketch of the present utility model.
Embodiment
As shown in Figure 1, be provided with thermal energy converter 1 at the end of the outlet pipe 8 of diesel engine, thermal energy converter 1 is connected with water storage box 5.When diesel engine normally works, will produce a large amount of high-temperature tail gas, the high-temperature tail gas utilizing outlet pipe 8 to emit adds hot cooling water, and utilizes water storage box 5 to be collected by the cooling water after heating.
In oil sump 7, be provided with thermal energy converter 26, thermal energy converter 26 is connected with water storage box 5.When diesel engine cold start-up, utilize the high-temperature-hot-water circulating-heating fuel oil in water storage box 5 and lubricant oil, to solve the low temperature fuel oil of diesel engine in psychro-environment lower body and lubricant oil wax deposition problem.Meanwhile, the circulating water after thermal energy exchange can continue for the cooling water as diesel engine, to solve the too low problem of diesel engine body temperature under psychro-environment.
The suction tude 2 of diesel engine is provided with electric heating wire 3.When diesel engine cold start-up, by storage battery heating electric heating wire 3 and cool air, thus solve diesel engine under psychro-environment, because intake temperature is too low, piston is difficult to compression ignite gas mixture, causes starting failed problem.
