Engine knocking. In spark-ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but when one or more pockets of air/fuel mixture explode outside ...
An ignition interlock device or breath alcohol ignition interlock device ( IID or BAIID) is a breathalyzer for an individual's vehicle. It requires the driver to blow into a mouthpiece on the device before starting or continuing to operate the vehicle. If the resultant breath-alcohol concentration analyzed result is greater than the programmed ...
DOHC 4 valves x cyl. The M176/M177/M178 is a petrol V8 engine range designed by Mercedes-AMG, replacing the M278 and M157 engines, and is based on the M133 engine. [1] The engine has two BorgWarner turbochargers positioned between the two cylinder heads in a "hot-V" configuration. The fuel injection system uses Bosch's new piezo-electric direct ...
The firing order of an internal combustion engine is the sequence of ignition for the cylinders. In a spark ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated. In a diesel engine, the firing order corresponds to the order in which fuel is injected into each cylinder.
Wasted spark system. A wasted spark system is a type of ignition system used in some four-stroke cycle internal combustion engines. In a wasted spark system, the spark plugs fire in pairs, with one plug in a cylinder on its compression stroke and the other plug in a cylinder on its exhaust stroke. The extra spark during the exhaust stroke has ...
The Air National Guard intelligence unit involved in the massive classified documents leak by an airman last year has been recertified and will return to its mission on Saturday after months of ...
The GM L3B engine is a turbocharged four-cylinder gasoline engine designed by General Motors. It is an undersquare aluminum DOHC inline-four displacing 2.7 liters (165 cid) and tuned for strong low-end torque. In addition to GM's active fuel management, start-stop system, and variable valve timing, which are already featured on GM's other full ...
Polari, a jargon that began in European ports and evolved into a shorthand used in gay subcultures, influences much of today's slang in words like "zhuzh," "drag," "camp" and "femme."
