Description
INDEPENDENT INSTALLATION
TO KEEP WARM AND ECONOMIC OPERATION OF THE LOCOMOTIVE DIESEL ENGINE
The invention relates to an installation used to keep warm the diesel engine of the locomotive ensuring its economic functioning. The installation is independent from the energy sources of the locomotive (accumulator batteries or traction diesel engine) and from the external power sources (electric supply network or static generator set).
It is known that keeping warm the locomotive diesel engine is achieved using external energy sources or, if they lack, by the continuous operation, at idle or intermittently of the engine, through manipulation by an operator.
Current warm keeping systems of locomotive diesel engine have the following disadvantages:
- Diesel locomotive is dependent on the presence of external sources of energy, during long stationary or in the shed, which is difficult to achieve in terms of railway operation;
- In the case of warm self-maintaining of the traction diesel engine, wear and high fuel consumption are very expensive leading to growth of the costs for railway transport and maintenance and also to the increase of the environmental pollution;
- The presence of the driver or operator to supervise warm-keeping of the traction diesel engine increases costs and induces some subjectivism in the operation mode;
- When the locomotive is operating and a long stationary is imposed by the operation schedule, in addition to keeping warm the traction diesel engine, there are required more other necessities such as: heating / air conditioning of the driving cab, providing compressed air for the train brakes etc. All these are achieved by diesel traction diesel engine operating at idle speed.
The process of maintaining the locomotive ready for operation is in reality more complex because it must include primarily keeping warm the traction diesel engine and heating the driving cab, but also keeping the accumulator battery charged when the locomotive is operating. Thus the locomotive is ready for hauling the train.
The technical problem solved by this invention is the optimization of keeping warm the traction diesel engine, extending the concept of „keeping warm" to the accumulator battery and the driving cab. The invention also provides all the necessary conditions to start the traction diesel engine any time for the railway operation regardless the locomotive is active or inactive (long stationary or in the shed) and also meets the following conditions:
1. Energy source must not dependent on external sources or on these existing on the locomotive, must not impose limitations to the transport operation and must keep warm the locomotive in all situations;
2. To provide functioning of the other auxiliary services for the locomotive when it is stopped in operation schedule or when it is at long stationary in order that the diesel engine has optimum parameters able to start in all situations;
3. To have minimum fuel consumption, to be easy to handle and to reduce pollution produced by the locomotive during railway operation.
The independent installation to ensure keeping warm and economic operation of the locomotive diesel engine, according to the invention, comprises an auxiliary diesel engine acting an three-phase synchronous generator, an voltage adapter particular for different types of locomotives, an electric or thermal heater mounted into the cooling system which heats the coolant, a low power water pump that ensures the permanent circulation of the coolant while maintaining it hot, a system of temperature sensors that controls the heating to be kept within optimum temperature limits of the coolant prescribed by the engine manufacturer.
The installation, according to the invention, depending on the operating mode of the locomotive (active or long stationary or in the shed) can be operated manually by start - stop switches mounted in the driver's cab, or automatically according to the coolant temperature through a temperature sensor.
The installation, according to the' invention, comprises a PLC (programmable logic controller) for control and monitoring of the operation, a recorder and a display for visualization the functioning parameters thus providing automatic control of the operation of the whole process without the need for human intervention. Surveillance and data collection of the functioning of the installation are automatically transmitted to a central dispatcher who coordinates the transport activity.
The installation, according to the invention, simultaneous provides keeping warm the traction diesel engine and the charging of the locomotive accumulators batteries so that the locomotive is ready for operate at any time.
The installation, according to the invention, may be completed by the application of the invention proposed by the invention documents A/00838/25.08.2011 (registered to Romanian State Office for Inventions and Trademarks), using for this purpose the same temperature sensor, automatic device for control and monitoring of the operation, recording and transmitting the operating parameters to a central dispatcher.
The invention presents the following advantages:
- Reduces fuel and oil consumptions;
- Reduces the wear of traction diesel engine and of the auxiliary services of the locomotive;
- Reduces the polluting effect of traction diesel engine exhaust gas by reducing its idling time;
- Removes the danger of forming ice plugs in the exposed areas of the cooling installation during the cold season;
- Represents a complete installation for keeping ready for operation the diesel locomotive because it ensure two functions: first, it maintains traction diesel engine warm and also the heating / air conditioning of the driving cab and second, the charging of the accumulator batteries;
- The total quantity of heat radiated by the auxiliary diesel engine remains into the locomotive car-body helping to keep it warm;
- Removes human subjectivity in the process of keeping warm the diesel engine by implementing an automatic system of command, monitoring, recording and communication;
- Extends the time between two maintenance inspections of the diesel engine and locomotive auxiliaries services;
- Extends the life of the accumulator battery by reducing the overload necessary to start the diesel engine because this is already warm, and the accumulator battery is charged during warm maintaining period.
- Uses the advantages of "Installation for increasing the efficiency of traction diesel engine", according to the invention documents A/00838/25.08.201 1 (registered to Romanian State Office for Inventions and Trademarks).
