Crankcase dilution occurs when the fuel oil from the engine gets into the lube oil of the engine. This can be caused by the walls being wetted due to the fuel condensing in the cylinder. 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 ...
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 ...
A Ford Excursion SUV next to a Toyota Camry compact. Sport utility vehicles (SUVs) have been criticized for a variety of environmental and automotive safety reasons. The rise in production and marketing of SUVs in the 2010s and 2020s by auto manufacturers has resulted in over 80% of all new car sales in the United States being SUVs or light trucks by October 2021.

These blow-by gases, if not ventilated, inevitably condense and combine with the oil vapor present in the crankcase, forming oil sludge. Excessive crankcase pressure can furthermore lead to engine oil leaks past the crankshaft seals and other engine seals and gaskets. Therefore, it becomes imperative that a crankcase ventilation system be used.
This variant of the Camaro was included in Time magazine's list of "The 50 Worst Cars of All Time"; Dan Neil said of it, "As the base engine for the redesigned 1982 Camaro (and Pontiac Firebird), the 2.5-liter, four-cylinder “Iron Duke” was the smallest, least powerful, most un-Camaro-like engine that could be and, like the California ...
In early June, Toyota announced the recall of nearly 100,000 Tundra pickups and about 3,500 Lexus luxury SUVs to fix a problem that could cause their engines to lose power while driving.
It can be mistaken for lubricating oil in some cases, but it consists of the "heavy ends" of the diesel fuel which do not burn when combustion temperature is too low. The heavier, more oily components of diesel fuel contain more stored energy than a comparable quantity of gasoline, but diesel requires an adequate loading of the engine in order ...
Motor oil, engine oil, or engine lubricant is any one of various substances used for the lubrication of internal combustion engines. They typically consist of base oils enhanced with various additives, particularly antiwear additives , detergents, dispersants , and, for multi-grade oils, viscosity index improvers .
