Abstract

The utility model discloses an engine low temperature starting preheating device. The device is provided with a heating body [1] which is provided with an installation hole [4] and is fixed on the motor body oil bottom shell. The characteristic is that the heating body [1] is provided with at least a group of heating component [3] and cycle water pipe [2]. The advantage is that the heating body firstly preheats the lubricating oil by the oil bottom shell of the motor, then preheats the cylinder head of the engine and the machine body via the cycle water pipe which is connected with the machine body and the cylinder head, thus the engine can be successfully started in cold winter. The device is especially suitable for the preheating before starting of the gasoline engine and diesel engine which are used in the north of our country.

Description

A kind of engine cold-starting Preheating unit

Technical field the utility model belongs to the additional device of motor, particularly a kind of engine cold-starting Preheating unit.

The startup of the present motor of background technique in the winter of cold needs preheating, because the design of motor itself need be heated by the device in the external world.Preheating methods such as the place employing steam that in early time, condition is good are more effective.Along with development, vehicle to get up, and particularly recent years, bicycle is more and more, and the method for this concentrated preheating can not satisfy the needs of each side.For this reason, various engine start pre-heating mean and device have been proposed.The oil sump of disclosed band oil preheating device in the Chinese patent 01268620.4 has wherein proposed the Preheating unit of oil sump, but does not have the preheating of proposition to body and cylinder head in this device.In some place, startup still is affected.Proposed the purpose of this utility model, task of the present utility model provides a kind of engine cold-starting Preheating unit for this reason.

This engine cold-starting Preheating unit of summary of the invention, this device has one and has on it by mounting hole [4] and be fixed on heating unit [1] on the engine body oil sump, it is characterized in that having one group of heating element [3] and circulating pipe [2] at least in heating unit [1] inside.Its advantage is that the oil sump that heating unit passes through motor at first is the lubricant oil preheating, by cylinder head and the body preheating to motor of the circulating pipe that is communicated with body, cylinder head, makes motor can start smoothly in the winter of cold then.Be particularly suitable for the petrol engine of northern China use and the preceding preheating of startup of diesel engine.

Appended drawings 1 is a plan view of the present utility model, and accompanying drawing 2 is A-A sectional views of accompanying drawing 1, and accompanying drawing 3 is flow charts of an application example of this device.The meaning that sequence number is in the accompanying drawings represented is: 1, heating unit, 2, circulating pipe, 3, electric heating element, 4, mounting hole, 5, oil sump, 6, cock of water drain, 7, body, cylinder head.

Embodiment is with reference to accompanying drawing, and the heating unit of this device [1] is fixedly mounted on the engine body oil sump [5] by mounting hole [4], and the oil sump of itself and motor is combined closely.At least have one group of heating element [3] and circulating pipe [2] in heating unit [1] inside.Heating element [3] preferably adopts electric heating element, for example has prevailing resistance wire or electrical bar good and extraneous electrical insulation.Electric heating element and extraneous power connection can adopt 220 volts civil power or power autonomous, also can adopt DC electrical source.The two ends of circulating pipe [2], an end connects the circulating cooling water pipe of engine body, cylinder head [7], and the other end connects the cooling water cock of water drain [6] of motor.After electric heating element [2] is connected power supply, the electric heating element heating, at first heat passes to oil sump [5], preheating lubricant oil by heating unit [1]; And then, circulating water in the circulating pipe [2] in the heating unit also is heated, under the effect of hot kinetic energy, and the very fast water cycle that forms heat at engine interior, make the body of whole motor, the position of cylinder head obtain preheating, just motor integral body has been carried out preheating.Pre-heat problem before the startup of the thorough like this motor that has solved winter, severe cold area.Adapting to all kinds of motors uses.

Claims

1, a kind of engine cold-starting Preheating unit, this device has one and has on it by mounting hole [4] and be fixed on heating unit [1] on the engine body oil sump, it is characterized in that having one group of heating element [3] and circulating pipe [2] at least in heating unit [1] inside.
