CN202718759U - Automatic input controller for engine cleaning agent - Google Patents

Abstract

The utility model relates to an automatic input controller for an engine cleaning agent. The automatic input controller comprises a singlechip, an electromagnetic valve, a liquid level meter and an engine controller, wherein the electromagnetic valve, the liquid level meter and the engine controller are respectively connected with the singlechip; the rotary speed signal of an engine is acquired by the engine controller and then is transmitted to the singlechip, and the output of the cleaning agent is controlled by controlling the starting and stopping frequencies of the electromagnetic valve by the singlechip. As the quantity of the cleaning agent input into the engine is determined according to the rotary speed signal, the gummy matter and dust in the engine can be efficiently removed without detaching the engine. The automatic input controller provided by the utility model is simple in structure, flexible and convenient in operation, and can reduce the accident rate when the engine is repaired.

Description

The automatic input control device of engine washing agent

Technical field

The utility model relates to a kind of auto parts machinery, specifically the automatic input control device of a kind of engine washing agent.

Background technique

In the Vehicle Driving Cycle, because the carbon distribution that forms after the colloid in the fuel oil and the burning causes that fault is more common, though defect is little very harmful.Want to get rid of these faults, the colloid in just necessary decarbonizing and the gasoline, but the method that present many vehicle repairing factories generally adopt is still cleaning behind the engine stripping again.This method, it is expensive not only to waste time and energy, and effect is unsatisfactory.More can't remove the colloid in fuel tank and the fuel tank.Also be not suitable for simultaneously the motor of current automobile.Because current motor car engine is to assemble by strict technological requirement under the dustless super stationary ring of constant temperature border.If ressemble after the disassembly, cleaning, its power, sealability can't be compared with original performance again.

The model utility content

The purpose of this utility model just provides the automatic input control device of a kind of engine washing agent, to solve colloid and carbon distribution problem not easy to clean in the motor.

The utility model is achieved in that the automatic input control device of a kind of engine washing agent, includes:

Single-chip microcomputer is connected with solenoid valve, level meter and engine controller, is used for adopting the tach signal of motor and the liquid level signal of detergent container, and sends keying signal to solenoid valve;

Engine controller is connected with described single-chip microcomputer, is used for sending tach signal to single-chip microcomputer;

Solenoid valve is connected with described single-chip microcomputer, is used for being undertaken by the keying signal that receives the single-chip microcomputer transmission opening and closing of detergent container; And

Level meter is connected with described single-chip microcomputer, is used for sending to single-chip microcomputer the liquid level signal of detergent container.

The utility model gathers the tach signal of motor by engine controller, then sends single-chip microcomputer to, and is controlled the output quantity of detergent by the frequency of the keying of Single-chip Controlling solenoid valve.Because the amount of the detergent of input motor decides according to tach signal, so need not to dismantle colloid and the dust stratification that motor can be able to be removed engine interior efficiently.The utility model is simple in structure, and flexible operation is easy, the accident rate when having reduced engine maintenance.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Among the figure: 1, single-chip microcomputer, 2, engine controller, 3, solenoid valve, 4, level meter.

Embodiment

As shown in Figure 1, the utility model includes single-chip microcomputer 1, is used for sending to single-chip microcomputer 1 level meter 4 of the liquid level signal of detergent container, the keying signal that receives single-chip microcomputer 1 transmission carries out the solenoid valve 3 of the opening and closing of detergent container, sends the engine controller 2 of tach signal to single-chip microcomputer 1.Wherein, solenoid valve 3, level meter 4 and engine controller 2 are connected with single-chip microcomputer 1 respectively.Level meter 4 is positioned in the container of depositing detergent, is provided with solenoid valve 3 at this container to the delivery port place of the conveying detergent of motor.Gather the tach signal of motor car engines by engine controller 2, then send single-chip microcomputer 1 to, and by the frequency of the keying of single-chip microcomputer 1 control solenoid valve 3, realize the control of detergent output quantity.
