Engine flooding was a common problem with carbureted cars, but newer fuel-injected ones are immune to the problem when operating within normal tolerances. Flooding usually occurs during starting, especially under cold conditions or because the accelerator has been pumped. It can also occur during hot starting; high temperatures may cause fuel ...
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.
Code mutation produces faults which are very similar to those unintentionally added by programmers. A refinement of code mutation is Code Insertion Fault Injection which adds code, rather than modifying existing code. This is usually done through the use of perturbation functions which are simple functions which take an existing value and ...
The BMW N43 is a naturally aspirated four-cylinder petrol engine which was sold from 2006 to 2013. It replaced both the BMW N46 and BMW N45 engines. [1] However the N43 was not sold in countries with high sulfur fuel, [2] therefore the N45/N46 engines remained in production alongside the N43.
Code injection is the malicious injection or introduction of code into an application. Some web servers have a guestbook script, which accepts small messages from users and typically receives messages such as: Very nice site! However, a malicious person may know of a code injection vulnerability in the guestbook and enter a message such as:

Indirect injection in an internal combustion engine is fuel injection where fuel is not directly injected into the combustion chamber. Gasoline engines equipped with indirect injection systems, wherein a fuel injector delivers the fuel at some point before the intake valve , have mostly fallen out of favor to direct injection .
Before the invention of precombustion chamber injection, air-blast injection was the only way a properly working internal air fuel mixture system could be built, required for a Diesel engine. During the 1920s, [ 2 ] air-blast injection was rendered obsolete by superior injection system designs that allowed much smaller but more powerful engines ...
