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 ...
Tell-tale (automotive) A group of tell-tales showing lights for "brake fluid", "stop lamp" and "check engine". Graphical tell-tales. A tell-tale, sometimes called an idiot light[ 1] or warning light, is an indicator of malfunction or operation of a system, indicated by a binary (on/off) illuminated light, symbol or text legend.
The engine temperature on modern cars is primarily controlled by a wax-pellet type of thermostat, a valve that opens once the engine has reached its optimum operating temperature. When the engine is cold, the thermostat is closed except for a small bypass flow so that the thermostat experiences changes to the coolant temperature as the engine ...
A heater core is a radiator -like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core, a heat exchanger between coolant and cabin air. Fins attached to the core tubes serve to increase surface area for heat transfer to air that is forced past them by a fan, thereby ...
Even with these in place, the SCADA system is reported to have detected only 19% of leaks, and the CPM system only detecting 10% of leaks. [ 2 ] [ 1 ] The primary purpose of leak detection systems (LDS) is to help pipeline controllers to detect and localize leaks.
Ford Model T engine. Side view of the Ford Model T engine. [ 1] The Ford Model T used a 177 cu in (2.9 L) sidevalve, reverse-flow cylinder head inline 4-cylinder engine. It was primarily a gasoline engine. It produced 20 hp (14.9 kW) for a top speed of 45 mph (72 km/h). It was built in-unit with the Model T's novel transmission (a planetary ...
The patient should remain in the ice bath until their body temperature falls to 102.2 degrees. Then, they can be transported to the hospital. Preparing for heat illness in a warming world
The temperature at which a chemical ignites decreases as the pressure is increased. Substances which spontaneously ignite in a normal atmosphere at naturally ambient temperatures are termed pyrophoric. Autoignition temperatures of liquid chemicals are typically measured using a 500-millilitre (18 imp fl oz; 17 US fl oz) flask placed in a ...
