Abstract
The invention discloses an oil saving method for a diesel automobile, and its technical solution has key points of: transmitting engine speed variation information to a speed sensing device with movable component in the automobile operating course, using corresponding component action caused by speed variation to implement oil-feed or not-oil-feed dynamic spacing for the load control level of a diesel jet pump for controlling oil quantity, thus not consuming the oil in all ordinary working conditions (including level roads and slopes) of forced running by vehicle inertia. The invention is easy to implement and does not influence normal operation of a driver and normal running of the vehicle; it has obvious oil-saving effect, and can assure enough brake air and illumining electricity.
Description
Technical field
The present invention relates to the automobile energy-saving technology field, particularly a kind of oil-saving method of diesel vehicle.
Background technique
Automobile is after startup and when not travelling, and keeps the rotating speed that the motor minimum speed stably runs well and is called free idling; After the vehicle driving, because some special running statees of driving procedure, be called by the strong engine speed of carrying out sailing of the inertia of vehicle own and push away idling by force, the fuel consumption of motor when above-mentioned two kinds of idling operations is called the idling oil consumption.
Because different vehicle motors has different idling performance requirements, set the minimum idling speed fuel delivery of motor car engine, traditional method be at diesel injection pump special position with the spacing adjusting screw of the idling of special use to that fixed point is set is spacing in order to control load control lever this oil pump feed amount, that link with accelerator pedal, and after setting up that adjusting screw is fastening, be locked in setting; The position promptly is regarded as the forbidden zone once locking.
This traditional fixed point limit method of diesel injection pump idling fuel feeding is regarded as unique engine idle point limit method always, the deficiency of this method is to make motor can rely on the strong common operating conditions of carrying out sailing and need not oil consumption of the inertia of vehicle own all to want to consume the idling fuel oil in the vehicle drive process in a large number originally unavoidablely.
Summary of the invention
The technical problem to be solved in the present invention, provide a kind of vehicle is in operation all can rely on the strong common operating conditionss of carrying out sailing of the inertia of vehicle own to need not the oil-saving method of diesel vehicle of oil consumption.
In order to address the above problem, the present invention realizes with following technological scheme:
A kind of oil-saving method of diesel vehicle, put under the prerequisite of minimum fuel delivery having set the diesel engine idling, give the revolution speed sensing setting have movable link with the be in operation information transmission of engine speed change of vehicle, the respective members action that utilizes rotation speed change to produce, to the diesel injection pump in order to the control fuel delivery, the load control lever that links with accelerator pedal is implemented the fuel feeding and the dynamic state limit of fuel feeding not: in the vehicle drive process, when to put one's foot down, load control lever promptly moves to the oiling direction, engine speed increases, and movable link oppositely moves on to not fuel feeding position; When lifting the full pine tar door of accelerator pedal, load control lever is retired not fuel feeding position immediately, make diesel injection pump fuel cut-off, when engine speed drops to the idling point revolution of approaching setting, being in not, the movable link of fuel feeding position promptly moves on to the fuel feeding position to load control lever, make the diesel injection pump recover fuel feeding, thereby reach the purpose of saving the idling oil consumption.
Described and the corresponding movable link of rotary speed information can be the members of actuatings such as air pressure, hydraulic pressure, vacuum, electromagnetism, machinery and automatical control system: also can be that described any actuating mode and other described actuating modes make up the member of actuating.
The invention has the beneficial effects as follows: 1, simple in structure, implementing does not influence the normal running of driver and the cruising of vehicle easily; 2., the using process neutral gear that need not stop working slides, avoiding driver is to save the fuel oil violation operation: all can rely on the strong common operating conditions of carrying out sailing (comprising level road, slope) of the inertia of vehicle oil consumption not entirely own in the process of moving 3, can to make vehicle, ramp many more, steep more, long more (for example hilly countries, mountain area), its oil-saving effect is more for obvious: the motor that 4, pushes away rotation is by force still driving inflating pump and generator work, and sufficient brake usefulness gas and electric consumption on lighting are arranged.
Description of drawings
Accompanying drawing is a principle of the invention schematic representation.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in detail:
In the accompanying drawing, the engine speed sensing is provided with the movable link that has corresponding actions with respect to the rotary speed information that changes; The load control lever of diesel injection pump is controlled fuel delivery and is linked with accelerator pedal; Can keep the idling that the motor minimum speed stably runs well and put under the minimum fuel delivery prerequisite having set the diesel injection pump, give described revolution speed sensing setting with the information transmission of engine speed change in the vehicle operating, the respective members action that utilizes rotation speed change to produce is implemented the fuel feeding and the dynamic state limit of fuel feeding not to the load control lever of diesel injection pump; In the vehicle drive process, when to put one's foot down, load control lever promptly moves to the oiling direction, and engine speed increases, and movable link is oppositely retired not fuel feeding position; When lifting the full pine tar door of accelerator pedal, load control lever is transferred to not fuel feeding position, the instant fuel cut-off of diesel injection pump immediately; At this moment, because of the inertia of vehicle pushes away effect by force, motor is under different running environment conditions, rotating speed does not descend immediately, keeping not under the fuel feeding state always, when engine speed drops to the idling point revolution of approaching setting, this rotation speed change information is input to the revolution speed sensing setting, this setting drives immediately and is in the not movable link of fuel feeding position (being equivalent to movably idle adjusting screw), the load control lever that is in same position is moved on to the fuel feeding position, make the diesel injection pump recover fuel feeding in advance automatically, thereby reach the purpose of saving the idling oil consumption.
Described and the corresponding movable link of rotation speed change information can be the member of pneumatic actuation.
Described and the corresponding movable link of rotation speed change information also can be the member of hydraulic actuating.
Described and the corresponding movable link of rotation speed change information also can be vacuum actuated member.
