what is cold starting of an engine?
93536
When Scientists and Engineers complete the building of a particularly new engine, the initial running test of this engine is termed as a "cold start", or basically the test run of the new engine.  Another interpretation is the initial starting of any engine from its cold state.  Therefore, at anytime an engine is initialize to start, the period from when the engine is cold and running is referred to as a "COLD START".  Since all machines normally becomes hot as it gradually reach normal operating temperatures. Some engines are given a cold start to initialize it, as it gradually reach normal operating temperature, only then are they given a load, or engaged to do work. Cold starting prepares the engine and its parts to reach normal operating temperatures so that all of the function and processes can run smoothly within the normal conditions and parameters that it is expected to operate on and further monitored by sensors to maintain its safe operation.\n~meow

A cold front is the boundary between two different air masses where cold air pushes warm air out of the way and brings colder weather, or just simply a gust of cool air.\n\nhope it helps. =]

I believe it's cooled to prevent pre-detonation of the fuel/air charge in the cylinder. So, if you send the hot gasses back into the manifold without cooling, you'll get knocking in the engine.

Good 4 tires and brakes, motor & transmission, chasis/frame, heater to keep you warm during cold winter, etc, the most important of all these is our brain to control it in safetely manner and enjoyable for the freedom on open road. Happy motoring. The Car Guy

I guess it can be done, but since your car isn't as well-insulated as your freezer, you'll need to change your AC and use a lot of power in order to do it. More power means a larger engine (more expensive) and more gas consumed (MORE expensive). You can also try buying a refrigerated truck and hanging out at the back.

Aside from finding it odd that it being a 'race car' wouldn't know the answer to this..\n\nReplace the 'anti-freeze' with Liquid Performance coolant or Engine Ice (about $10 a quart). Anti-freeze is a horrible conductor of heat, it's sole purpose is to lower the freezing point of the water it is mixed with. Freezing shouldn't be an issue on a 'race car'. Engine Ice will run cooler while still protecting the cooling system parts, Liquid Performance will run even cooler and offers freeze protection.\n\nReplace the thermostat with a lower stat, or remove it completely.\n\nNow, why is this a bad thing? Because, the computer that runs your car is designed with two 'modes'. One is the default 'limp' mode, which uses pre-programmed settings for timing, fuel, etc. It uses this mode anytime there is a problem, as well as before the system reaches operating temp. This temp is hard-coded into the ECM. Lowering the running temp of the engine below this point will cause the computer to resort back to 'limp' mode.\n\nIf the car is simply running hot, you could have:\nLow coolant or coolant mixed to 'rich'.\nclogged/restricted cooling system, either internal or external.\nbad thermostat (won't open or opens too slowly).\nbad radiator cap (won't hold pressure or holds too much).\nSlipping water pump belt.\nBad water pump (leaking, impeller worn/loose/etc).

The Stirling engine, also known as the hot air engine, is a heat engine of the external combustion piston engine type. Its invention is credited to the Scottish clergyman Rev. Robert Stirling in 1816 who made significant improvements to earlier designs and took out the first patent. He was later assisted in its development by his engineer brother James Stirling.\n\nThe Stirling engine works by the repeated heating and cooling of a sealed amount of working gas, usually air or other gases such as hydrogen or helium. The gas follows the behaviour described by the gas laws which describe how a gas' pressure, temperature and volume are related. When the gas is heated, because it is in a sealed chamber, the pressure rises and this then acts on the power piston to produce a power stroke. When the gas is cooled the pressure drops and this means that less work needs to be done by the piston to re-compress the gas on the return stroke, giving a net gain in power available on the shaft. The working gas flows cyclically between the hot and cold heat exchangers.\n\nThe working gas is sealed within the piston cylinders, so there is no exhaust gas, (other than that incidental to heat production if combustion is used as the heat source). No valves are required, unlike other types of piston engines.\n\nSee Wikipedia for more information, above courtesy of Wikipedia.

To reduce strain on the electrical system when starting the motor (needs that initial "kick" to get it going and would overload most systems).

One very important application for viscosity that affects much of the world is the rating of engine oils.  For example 10W30 engine oil behaves as though it has a low viscosity (10) while cold during startup but thickens due to the action of special polymers when hot (30).  This increases the flow of cold oil improving initial lubrication while reducing engine wear.  The specific oil viscosity grade selected may depend on the season and the minimum temperature expected (especially where bitterly cold).  This can be an important safety consideration allowing a sure start when the battery exhibits minimum power, preventing people from being stranded in the cold.  When I worked at Brookfield Engineering (long ago) they shipped viscosimeters all over the world for use in chemical plants including paint factories.

You don't make a fluid cold by passing a current through it; that's violate the laws of thermodynamics.  You make a fluid cold by throttling it (ie passing it through a narrow opening from high pressure to low pressure) and making it expand.

Most stock engines run 4 to 7 psi.

check your automatic choke. if your choke is engaged when your engine is warm, adjust your choke setting. also, old mustangs have a problem with leaky fuel lines, so check those.

About 36-40C idle 46C the most on load. You would be fine up to 60C but that would be not really an ideal temp for sure.

airplane: hot exhaust mixes with the extremely cold air, makes contrails, when it cools off it goes away\npan: water boils at a much lower temp than oil, if you got oil hotter it would sizzle too

They're called contrails, short for condensation trails. When a jet engine is running it heats up the air traveling through it.  On the ground it's not that noticeable.  Up in the atmosphere where jets fly, the temperature is way below freezing. The warm moist air condenses as it exits the jet engines and you can see the water vapor the same way you can see your breath on a cold day.
