Development of an ac system using waste heat of an ic engine

Air-cooled engine Cars and trucks using direct air cooling without an intermediate liquid were built over a long period from the very beginning and ending with a small and generally unrecognized technical change. The study shows the availability and possibility of recovery of the waste heat from internal combustion engine using Stirling engine.

In the turbine the steam pressure and temperature is lowered as the internal energy of the steam is converted to work. The industry term for the antifreeze mixture is engine coolant. The peak delivery is 10 million pounds per hour or approximately 2. Finally, other concerns may dominate cooling system design.

For all practical purposes this steam has negligible useful energy before it is condensed.

This is called a condensing turbine. For example, most cars and trucks use liquid-cooled engines, while many small airplane and low-cost engines are air-cooled.

The viscosity of oil can be ten times greater than water, increasing the energy required to pump oil for cooling, and reducing the net power output of the engine.

For vessels, the seawater itself is mostly used for cooling. Energy losses of internal combustion engine. Air-cooled engines may also vary their cooling capacity by using more closely spaced cooling fins in that area, but this can make their manufacture difficult and expensive.

In such cases, the heat from the CHP plant is also used as a primary energy source to deliver cooling by means of an absorption chiller. The instantaneous compression volume.

For example, the RU MHD generator in Moscow heated a boiler for a conventional steam powerplant, whose condensate was then used for space heat. Another method to recover exhaust heat is by the use of the Stirling engine technique. Steam supply and exhaust conditions.

Engines with higher efficiency have more energy leave as mechanical motion and less as waste heat. The capital and operating cost of high pressure boilers, turbines and generators are substantial.

Gas turbine CHP plants using the waste heat in the flue gas of gas turbines. Engine cooling removes energy fast enough to keep temperatures low so the engine can survive. Cogeneration systems linked to absorption chillers use waste heat for refrigeration. Thermally enhanced oil recovery TEOR plants often produce a substantial amount of excess electricity.

A typical engine coolant radiator used in an automobile Coolant being poured into the radiator of an automobile Today, most automotive and larger IC engines are liquid-cooled.

On the other side the main disadvantages and limitations can be concluded as long start-up time at cold starting, typically not self-starting, and finally being quite large and heavy.

Or they are designed, with or without extraction, for final exhaust at back pressure non-condensing. A CHP plant can either meet the need for heat heat driven operation or be run as a power plant with some use of its waste heat, the latter being less advantageous in terms of its utilisation factor and thus its overall efficiency.

After isolating the pump problem, cars and trucks built for the war effort no civilian cars were built during that time were equipped with carbon-seal water pumps that did not leak and caused no more geysers.

Cooling system regulation includes adjustable baffles in the air flow sometimes called 'shutters' and commonly run by a pneumatic 'shutterstat ; a fan which operates either independently of the engine, such as an electric fan, or which has an adjustable clutch; a thermostatic valve or just 'thermostat' that can block the coolant flow when too cool.

The subject of boiling engines was addressed, researched, and a solution found. Stirling Engine Effective Factors Usually the design point of a Stirling engine will be somewhere between the two limits of 1 maximum efficiency point and 2 maximum power point.

A more modern system might use a gas turbine powered by natural gaswhose exhaust powers a steam plant, whose condensate provides heat. Internal combustion engines remove waste heat through cool intake air, hot exhaust gases, and explicit engine cooling.

Steam may return to water as it mixes with other coolant, so an engine temperature gauge can indicate an acceptable temperature even though local temperatures are high enough that damage is being done.

After generating electricity, these plants pump leftover steam into heavy oil wells so that the oil will flow more easily, increasing production. In contrast, passing air over several hot objects in series warms the air at each step, so the first may be over-cooled and the last under-cooled.Internal combustion engine cooling uses either air or liquid to remove the waste heat from an internal combustion small or special purpose engines, cooling using air from the atmosphere makes for a lightweight and relatively simple system.

Abstract. This paper investigates the potential of utilizing the exhaust waste heat using an integrated mechanical device with internal combustion engine for the automobiles to increase the fuel economy, the useful power, and the environment safety.
