The oil circuit component and diesel engine put.
Background technology
Diesel engine is burning diesel oil to obtain exergonic engine, although diesel engine has the thermal efficiency
And the advantages that better economy, but because its fuel is diesel oil, diesel oil is big compared with gasoline viscosity, so, when temperature is relatively low
When, diesel oil can be made the problems such as thick solidifying, wax deposition, obstruction oil pipe occur so that diesel engine can not start.
In order to solve the problems, such as that cold snap causes diesel car to start, in the prior art typically using following two
Mode is realized；The first, changes the relatively low diesel oil of condensation point；Second, diesel oil oil way heating unit is added in diesel oil oil circuit.
Wherein, the scheme cost for changing the relatively low diesel oil of condensation point is higher；It is well known that according to national standard (GB252-87), light diesel fuel rule
Lattice are divided into 10,0, -10, -20, -35 and -50 six trades mark by condensation point, and are required according to GB252-2000 standards, from light diesel fuel
The trade mark should be in accordance with following principle：No. 10 light diesel fuels are applied to the diesel engine for having pre-heating device；No. 5 light diesel fuels are suitable for relative risk
Area use of 10% lowest temperature more than 8 DEG C；No. 0 light diesel fuel is applied to the lowest temperature that relative risk is 10% at 4 DEG C
Area use above；- No. 10 light diesel fuels are applied to the area of the lowest temperature that relative risk is 10% more than -5 DEG C and used；-
No. 20 light diesel fuels are applied to the area of the lowest temperature that relative risk is 10% more than -14 DEG C and used；- No. 35 light diesel fuels are applied to
Area use of the lowest temperature that relative risk is 10% more than -29 DEG C；It is 10% most that-No. 50 light diesel fuels, which are applied to relative risk,
Area use of the low temperature more than -44 DEG C；According to above-mentioned standard, Northern Part of China whole winter is to make diesel engine just
Often work, will use-No. 20 or-No. 35 diesel oil, this cost is huge.It is so most of using in diesel oil oil circuit at present
The mode of middle addition diesel oil oil way heating unit solves the above problems.

Hot type.Wherein, additional heat type is the outside that heater is arranged on to fuel tank, oil pipe, coarse cleaner, thin Cleaner, by extroversion
Interior heating, although this mode of heating security is preferable, its thermal efficiency is low, firing rate is slow, battery electric energy consumption is big,
Shorten the service life of battery.And interior hot type, it is that quick-heating type heater is directly inserted into each component of oil circuit, its
Although overcoming the problem of additional heat type heater firing rate is slow, this kind of fast heat apparatus, it is necessary to heater at several seconds
It is interior to produce larger heat so that diesel oil wax deposition moment melts, such as improper use, easily produces asking of dissolving diesel oil oil pipe
Topic, have a strong impact on the safety of automobile.
