Definitions
- the present invention relates to a lubricating oil composition for internal combustion engines.
- the present invention relates to a lubricating oil composition for automobile engines
- the present invention relates to a lubricating oil
- composition for the internal combustion engines that is excellent in fuel efficiency, oil consumption control and detergency.
- crankcase lubricating oil A problem with crankcase lubricating oil is that the lubricating oil is liable to escape from the crankcase due to so-called blow-by gas .
- the blow-by gas or such a gas / lubricat ing oil mixture is preferably recycled to the engine rather than being discharged to the atmosphere. In some engines, such recycling is carried out by injecting the blow-by gas into an air intake system of the engine so that the lubricating oil burns in piston chambers. Recycling of blow-by gas solves the problem of emissions, whereas it may cause problems such as formation of deposits in the air intake system. For example, when the deposits form in an air compressor, the compressor does not work well and is further susceptible to damage. Also, for
- viscosity characteristics by using friction modifiers to contribute to friction reducing performance, and by using viscosity index improvers to reduce agitation resistance and to maintain an oil film at high
- An object of the present invention is to provide a lubricating oil composition for internal combustion engines for further improving the invention according to JP2017119787 , the lubricating oil composition having a higher viscosity index and oil film retentivity so as to cope with advancing downsizing and high
- the present invention relates to a lubricating oil composition for internal combustion engines, comprising:
- a base oil composition containing a GTL base oil as a main component, and having %Cn of 14 to 25% and an aniline point of 120 to 126°C;
- a comb-like polymethacrylate based viscosity index improver having a weight average molecular weight (Mw) of 400,000 or more
