Description
The present invention relates to method and purposes, control spark-ignition internal combustion engine or compression ignition gasoline are related in particular aspects
Piston paint film in internal combustion engine(varnish)The method of formation, in terms of other in be related to the combination of additive as spark
Piston paint film in the fuel composition of igniting internal combustion engine or compression ignition gasoline engine controls the purposes of additive.The present invention
Further relate to control power output, fuel economy, engine scuffing, the method for piston ring sticking and gas blowby in engine.
In the running of spark-ignition internal combustion engine, blow-by gas enters engine oil pan from combustion chamber through piston face
Shell.Blow-by gas can carry fuel, lubricating oil, vapor and combustion product and can be deposited onto on piston metal surface.
Piston runs into high temperature on metal surface, and this causes these components to condense, be densified and partial oxidation paints sample material to be formed.Fuel
Chemical composition therefore be piston paint film formation speed and the order of severity in a factor.Piston paint film is more accumulate in it is low
Metal surface interstitial area(Piston friction surface district)In.
Piston paint film can reduce the performance of engine.For example, piston paint film can improve piston ring sticking, improve
A factor in gas blowby level, the engine scuffing level improved, the fuel economy of reduction and the power output of reduction.
Generally, using the formation of the additive control piston paint film in lubricating oil.According to US3784474 summary, contain
