The running pressure of a liquid-cooled engine is controlled by a?
Coolant pressure begins to rise above 0psi as coolant temp increases. The pressure cap on the radiator or elsewhere will contain this rising pressure until it reaches the preset spec. written on the cap. Then a relief valve opens, and coolant is vented to the overflow or the ground to maintain pressure. Usually about 15psi.
Not necessarily but usually
Pressure raises the boiling point.By changing the atmosphere inside the radiator the coolant will boil at a different temp than normal atmosphere pressure outside the radiator.By running it without that cap, you lower the boiling point to what it would be as if you were just heating int up in a pot.
try to make sense next time
Within a mechanical governor, the speed demand lever creates a spring force working against a force based on engine speed.The balance of these forces controls the volume of fuel injected into the engine.Applying machine load to the engine slows the engine speed.
to dissipate the residual heat in the radiator it will shut off automatically
On some makes of vehicle, the engine fan is supposed to keep running after the engine is shut off, if it was operating on a long trip on a hot day, for example. Come back to the car in 10-15 minutes. If the fan is still running, you have a problem. If it has shut off, all is well.
Boiling temperature of any liquid depends on the vapor pressure.Hence pressure cap is employed in cooling system, so that the system works on given high pressure and release the excess pressure in case of pressure build up due to high temperature conditions.
Your 1988 corvette has 3 dead cylinders why. the engine runs. there is a great amount of pressure inside the engine when running remove oil filler cap and the pressure come out very strongly.?
You may have broken rings in the 3 dead cylinders allowing compressed air-gas mixture to enter the crankcase.
I would check the Cooling Fan Switch/Relay. Sounds like it is a bad switch and stays 'on' well after it is needed, if it is running the battery down.
Water is used to cool down the car engine.it has high specific heat capacity.It can absorb a large amount of heat without a high increase in temperature.it is cheap and can be obtained easily.
Internal combustion engines remove waste heat through cool intake air, hot exhaust gases, and explicit engine cooling.Engines with higher efficiency have more energy leave as mechanical motion and less as waste heat.Engine cooling removes energy fast enough to keep temperatures low so the engine ...
The cooling system is designed to be pressurized to prevent coolant from boiling.However, too much pressure will cause hoses and other components to burst and leak, so a system is needed to relieve pressure if it exceeds a certain point.The cap releases pressurized coolant into the coolant overfl...
Approx 195 degrees. Cooling fans usually come on around 210-215 degrees
Like a lot of other questions, the answer is, "It depends."Most fuel injection systems these days are "port fuel injection" in that the fuel injectors are located upstream of the intake valve. Different manufacturers use different pressures, but most are in the range of 2-4 atmospheres (200-400 k...
What component separates the high pressure and low pressure sides of the air conditioning system and acts as a metering valve to control the flow of refrigerant?
Expansion valve or orifice tube.That sounds like the expansion valve.
Need to know year, make, engine and model of the vehicle.
Expansion of liquids is much greater than that of solids.When a liquid is heated in a container, heat flows through the container to the liquid, which means that the container expands first, due to which the level of the liquid falls.When the liquid gets heated, it expands more and beyond its ori...
The 1995 Pontiac 3.1 liter engine recommended fuel pressure is 17 pounds per square inch. The fuel pressure can vary a pound or two, and still be acceptable.
Is there a safety switch when a 1995 3000gt looses oil pressure and runs out of oil and ruins the engine?
No. that's why there are oil guages & warning lights. Some driver interaction is required in car upkeep.
AdvantageIt keeps your engine cold.Air cooling is a method of dissipating. It works by making the object to be cooled have a larger surface area or have an increased flow of air over its surface, or both. An example of the former is to add to the surface of the object, either by making them integ...
It's probably an electric fan that reacts and works if the engine reaches a certain temperature. Sometimes that means keeping going for a while even after you shut down the car.
A motorbike with liquid cooled engines is smoother and more resistant to breakdown than air-cooled.A liquid cooled engine, since cooled by liquids, maintains a better control temperature.Air-cooled engines are fuel efficient, affordable and require lesser engine space than that of liquid cooled e...
To allow the coolant to reach higher temperatures, with out boiling. When a liquid is pressurized, it can exceed it's boiling point and remain liquid, but when the pressure is released (like removing the pressure cap) the liquid is instantly tuned into super heated steam.
Its supposed to increase efficiency and safety a lot. its not water based so it doesn't turn to steam like typical coolant. Typical coolant is under pressure to raise the boiling point so when an engine is hot and a hose breaks or a cap is removed, the pressure drops, also dropping the boiling po...
With a higher altitude, there is a lower air pressure. This is caused by gravity pulling the gas molecules of our atmosphere closer to its surface. when the molecules are farther away from the Earth's surface the gravitational pull is weaker thus making the atmosphere thinner higher up and thicke...
Rocker arms, in conjunction with the camshafts, do so. The camshaft has an egg pattern on it, and this pushes the rocker arms up and down. The rocker arms are connected to the valves, and this puts the fuel/air mixture into the engine, then takes it out again
Remote control cars use battery and some cars can run on just battery so, yeah.
Such a vehicle does not exist. However should one be built (unlikely) it would need to have a speed control (accelerator) and means of stopping (brakes) incorporated as with all vehicles.
Every morning there is a puddle of red liquid under your car up near the front of the engine What is it?
The red liquid is transmission fluid. Whether you have a manual or automatic transmission, Saturn used ATF for both. You should get you car to a mechanic to find the leak before it causes damage to your transmission.
Common-rail direct fuel injection is a direct fuel injection system for diesel engines.On diesel engines, it features a high-pressure (over 100 bar or 10 MPa or 1,500 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles).
Your check engine light is on all the time engine is running your temperature gauge does not move when driving the car and your cooling fan continue to run for several minutes after turning engine off?
Check your coolant level, FIRST. If it's ok then let the vehicle run for a few minutes and check to see in the radiator is warm by quickly touching your hand to it (shut the vehicle off first and make sure your hand isn't anywhere near the fan! The electric fans can start even when the vehicle is...
When a coolant container is part of a pressurized system can the cap be removed while the engin is hot?
Which cap ? The radiator cap or the coolant top up expansion container.
What is the problem when a new idle air control valve is installed and the engine runs at a high r.p.m.?
Could have been installed incorrectly and may have damaged the valve.The year, make and model vehicle would also help.
Is this a real question? The engine is what propels the car. The engine powers the transmission,transmission turns the wheels.

Try disconnecting the temperature switch where the upper radiator meets the head. If it remains running them it is probably the fan timer unit located under the dash to the left of the steering column.

Cut-in and cut-out pressures are maintained by the air governor, while tank pressure is largely the purge valve.
By fans, I assume it has more than one. One of these fans will run continuously when the A/C is on. The other fan should only run when needed to cool the engine down. In stop and go city driving in the summer with the A/C on, both fans may very well run continuously. At highway speeds, only the A...
The basic rule of thermodynamics is that heat goes from where it's hot to where it's not. The coolant in a vehicle takes (draws or sinks) heat from the engine, and this heats the coolant. The hot coolant carries off the heat, and then flows through the radiator. Air passing the elements of the ra...
Diesel engine speed is controlled solely by the amount of fuel injected into the engine by the injectors.Because a diesel engine is not self-speed-limiting, it requires not only a means of changing engine speed (throttle control) but also a means of maintaining the desired speed.
All liquids show the following characteristics: Liquids are almost incompressible. Liquids have fixed volume but no fixed shape.They have fixed volume but they do not have fixed or definite shape. Liquids flow from higher to lower level.Liquids have their boiling points above room temperatu...
Depends on the thermostat. Most vehicles run a 195 thermostat and the engine coolant temp runs between 195 and 225.
There is this gauge you can buy it screws right into the spark plug port and when you turn your motor over slightly not starting it but just bumping the starter when you get the internals of the motor at a certain point it will read the exact max pressure in your cylinder.
The best way to cool down an overheated car engine is to park the vehicle. Allowing the engine to cool down naturally avoids all potential hazards and it is also safer for the engine. If you must start the cooling process immediately, pour cool water over the radiator and upper and lower hoses.
Most vehicles locate that sensor close to the thermostat housing.
A gas fills its container, taking both the shape and the volume of the container.Liquids and gases are called fluids because they can be made to flow, or move.In any fluid, the molecules themselves are in constant, random motion, colliding with each other and with the walls of any container.
The compression ratio of a combustion engine is the relationship of the largest and smallest capacities of the combustion chamber. A higher compression ratio is advantageous because the engine operates more efficiently, extracting more mechanical energy from the fuel. Most gasoline-powered engine...
GM just declared bankruptcy.
Nitrogen Dioxide (NO2 ) is produced by the sparking of air, the Carbon Dioxide (CO₂) is produced due to the combustion of carbon in the hydrocarbon fuel.
Liquid Cooling As this liquid passes through the hot engine it absorbs heat, cooling the engine.After the fluid leaves the engine, it passes through a heat exchanger, or radiator, which transfers the heat from the fluid to the air blowing through the exchanger.
So that a car will not over-heat and blow up
it is ignited due to the high temperature caused by the pressure inside cylinder, when it is compressed.
Either the Carbourator (older cars) or the ECU (fuel injected)
It is use full in the right situation. If you're going down a long steep hill you should leave your car in 4th or 5th and let it cruise down the hill at its own speed. This saves the brakes and also lets you have a more controlled descent, if you have a large load in say for example a truck you...
No, if the coolant circulates too quickly it will not have time to cool down and re-cool the engine. The coolant would become extremely hot, and cause your engine to overheat and thus causing possible engine damage.
Depends on if it is naturally aspirated or not. If it is, then it will always be under vacuum. If it has forced induction (turbo, supercharger), then the pressure could be anything.
It could be a carburetor (old school) or the fuel injection system.
Look on your dash inside of your car. Next to your speedometer will be your tachometer. if it is on anything but zero, your engine is running.
The mean effective pressure is a quantity relating to the operation of a reciprocating engine and is a valuable measure of an engine's capacity to do work that is independent of engine displacement. When quoted as an indicated mean effective pressure or IMEP (defined below), it may be thought ...
No airflow through rad
Absolutley. Depending on the engine size varies the amount of fuel loss due to A/C use. If you hop in a cheap 4 banger and put on the A/C you will notice a certain stain on the engine and maybe an increase in RPM's. So it will cause you to use more fuel but not enough to worry about. Myth Buster ...
Your AC absorbs the heat from your indoor air and deposits it outside.To get rid of the heat, the outdoor unit (the condensing unit) has a fan that blows air over the warm refrigerant line.This creates a major problem for your air conditioner because if it can't get rid of the heat, it can't cool...
