Embodiment 1

[0026] The present invention is designed with a new type of diesel engine starter for the existing method and the device difficult to meet the operation of the cold zone roller paver, and the operation timing fuel consumption is designed. The engine achieves a simple and reliable start of the cold zone operation by adopting measures such as valve decompression starting devices, piston nano treatment and cylinder gap, and achieves the solid self-lubrication function of the piston while reducing wear, reducing engine oil and diesel consumption. In addition, the apparatus and measures increase cost, the starting current is reduced, extend the life of the start motor and the piston.

[0027] like figure 1 As shown, the present invention discloses a diesel engine activation device based on the cold zone operation, including a pressure plate 2, a two-way electromagnet 4, a cylinder junction 7, and a valve 6, and the bidirectional electromagnet 4 is connected to the bottom surface of the...

Embodiment 2

[0034] Embodiments of the present application also provide a startup method, which uses the starting device in Example 1, and specifically includes the steps of:

[0035] Step 1, monitor the status and speed of the engine. In this step, monitoring can be monitored by monitoring or by the paver itself by the controller set in the engine.

[0036] Step 2, when the engine is started, the stopper 10 is in the first position to turn the valve 6 to open the reduced start boot.

[0037] Step 3, when the engine speed exceeds the set threshold, the stopper 10 is in the second position so that the valve 6 is turned off to achieve decompression start. In this step, the set threshold of the engine speed is set as needed, which can be set to 250 revolutions, 300 rpm, 350 rot, etc., when the engine starts, the speed will increase rapidly, and the set threshold is preferably rapidly promoted. The minimum of 250 rpm is 250 rpm.

Embodiment 3

[0039] Embodiments of the present application also provide an paver that can take the starting device in Example 1. The paver can be well implemented in the cold zone, saving oil and fuel consumption during construction work, extend the life of the piston and starting the motor.

Abstract

The invention discloses a diesel engine starting device and method based on cold region operation and a paver. The device comprises a pressing plate, a bidirectional electromagnet, a cylinder sleeve and an air valve, wherein the bidirectional electromagnet is connected to the bottom surface of the pressing plate, and a wiring device for electrifying the bidirectional electromagnet is connected to the pressing plate; a piston is arranged in an inner cavity of the cylinder sleeve, and the air valve communicates with an upper area defined by the cylinder sleeve and the piston; the output end of the bidirectional electromagnet is connected to a stopper, the bidirectional electromagnet is used for controlling the stopper to be located at a first position or a second position, and the stopper stretches out at the first position to prevent a rocker arm from returning so as to open the air valve; and at the second position, the stopper retracts, and the rocker arm returns to close the air valve. According to the device, the problem that a diesel engine is difficult to start due to a large load is solved, and as starting resistance is reduced, a peak current of a starting motor is also reduced, and the service life of the starting motor is prolonged.

Description

Technical field [0001] The present invention relates to the field of paver, and in particular to diesel engine starters, methods, and paver based on cold zone operations. Background technique [0002] At present, most of the roller pavers have more hydraulic systems, during the cold zone, due to the increase in the viscosity of the oil, it is difficult to activate, and the fuel consumption is high in operation, especially the oil consumption is high. In order to solve the problem of launching in the cold zone, most manufacturers use the method of heating of intake and coolant, or with a housing box or coupling with a hinged function, first cut off the power at startup, and start smoothly. However, these methods are not good starting effect, that is, waiting for the heating time, or too high, reliability and poor, need to find a simple and low cost solution, and low fuel consumption during operation, especially engine oil consumption Reduce. Inventive content [0003] It is an ob...
