If the engine is cold, or there is an excess amount of cooling around the cylinder, [1] the fuel oil will condense and have a higher chance to end up in the crankcase. [2] Another way that the fuel oil can end up in the crankcase is because there is too much wear on the piston compression rings. [1]
A lean fuel mixture or excessive amount of oxygen in the combustion chamber; An engine that is running hotter than normal due to a cooling system problem (low coolant level, slipping fan clutch, inoperative electric cooling fan or other cooling system problem) Auto-ignition of engine oil droplets (Can be solved by using an oil catch tank) [3]
The ignition source of a diesel engine is the heat generated by the compression of the air in the cylinder, rather than a spark as in gasoline engines. The dieseling phenomenon occurs not just because the compression ratio is sufficient to cause auto-ignition of the fuel, but also because a hot spot inside the cylinder (spark plug electrode ...
Since your car ($3,000) is worth much less than the 10x amount ($8,000), full coverage probably isn't the best value. It would mean spending $2,400 in premiums over just three years — nearly the ...
A vote to prohibit sales of gas-burning cars starting in 2035 will bring sweeping change to California's roads, but there's plenty of nuance in the fine print. California's coming gas car ban ...
Blow-by, as it is often called, is the result of combustion material from the combustion chamber "blowing" past the piston rings and into the crankcase. These blow-by gases, if not ventilated, inevitably condense and combine with the oil vapor present in the crankcase, forming oil sludge.
Between the drive there and back — and all the driving I did while I was there — I had to buy two tanks of gas. My car's fuel tank capacity is about 21 gallons so that would have typically set ...
In a gasoline engine, this inert exhaust displaces some amount of combustible charge in the cylinder, effectively reducing the quantity of charge available for combustion without affecting the air-fuel ratio. In a diesel engine, the exhaust gas replaces some of the excess oxygen in the pre-combustion mixture. [3]
