E10, a fuel mixture of 10% anhydrous ethanol and 90% gasoline sometimes called gasohol, can be used in the internal combustion engines of most modern automobiles and light-duty vehicles without need for any modification on the engine or fuel system. E10 blends are typically rated as being 2 to 3 octane numbers higher than regular gasoline and ...
Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.
Blow-by” gases are a mix of fuel oil and exhaust gases that push past the piston rings. Crankcase dilution is caused more when the lube oil is fresher. [3] Another cause of crankcase dilution is a slow or delayed injection cycle. [2] This causes the timing to be thrown off and the oil is most likely to enter the crankcase at this point.

For the past few decades though, most cars have been designed to tolerate up to 10% ethanol (E10) without problem. This includes both fuel system compatibility and lambda compensation [clarification needed] of fuel delivery with fuel injection engines featuring closed loop lambda control. In some engines ethanol may degrade some compositions of ...
Adding indirect injection keeps fuel spraying on the intake valves, reducing or eliminating the carbon accumulation on intake valves and in low load conditions, indirect injection allows for better fuel-air mixing. This system is mainly used in higher cost models due to the added expense and complexity. Port injection refers to the spraying of ...
The repair for this type of problem depends on the severity of the deposits. In milder cases, a mechanic may solve the problem by adding a can of fuel-injector cleaner into the gas tank. However, in some cases, the fuel injectors must be replaced. Deposits formed on the intake valves may be removed via walnut shell blasting.
Ethanol fuel has a "gasoline gallon equivalency" (GGE) value of 1.5, i.e. to replace the energy of 1 volume of gasoline, 1.5 times the volume of ethanol is needed. [4] [5] Ethanol-blended fuel is widely used in Brazil, the United States, and Europe (see also Ethanol fuel by country). [2]
