There is rotational, have HRB bearing (
)
Jiaxing bearing the author teaches you how to select the internal combustion engine oil.
Jiaxing bearing group sales co. , LTD. (
The company)
Is jiaxing bearing factory set up in the spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong cash supply ability.
How to select the internal combustion engine oil: (
1)
According to the characteristics of the internal combustion engine and vehicle, namely choose oil load and speed.
Load of high speed low, for example, some large bulldozers, cranes, and drill, etc. , generally choose larger lubricating oil viscosity, such as SF40, CD50, light load of high speed, such as cars, jeeps, small power equipment generally choose smaller viscosity lubricating oil, such as SG15W / 40, SF30, etc.
(
2)
According to the internal combustion engine work hard.
Such as diesel engine is a temperature higher than 230 - ring area
-
250 ℃, strengthening coefficient greater than 5, supercharged diesel engine oil with CD or more oil, such as CD40, SG/CD40, etc.
Gasoline engine according to the compression ratio and whether there is a crankcase positive pressure ventilation, exhaust gas recirculation, and selection of engine oil such as catalytic converter, the compression ratio, the greater the selection of engine oil level is higher, with the above attachment, generally choose SG more oil.
(
3)
Oil capacity and power ratio is also choose oil factor.
Oil capacity and power ratio is also choose oil factor.
Large capacity of the oil is not hard to product quality requirements, high quality demand of small oil capacity of oil.
General European production engine is small in size, big power, requires the use of high quality oil, such as SHSJ.
(
4)
According to the region, season, the temperature selected oil.
Winter cold area, should choose low viscosity, low pour point oil or multistage oil, such as the northeast region in China, can choose SF10W / 30, SH5W / 30, etc. ;
Higher temperature area throughout the year, such as hainan, guangdong, can choose the oil of high viscosity, such as SF40, CD50, etc.
(
5)
According to the abrasion of engine oil.
The new engine should choose smaller viscosity oil (
Considering energy saving)
, and wear large, cylinder wall and piston clearance big engine should choose larger viscosity (
Consider seal)
