How are hydro-carbons formed in an automobile engine: Hydro carbons are formed due to the unburnt portion of fuel,emitted from the engine exhaust. Hydro-carbons are the only major pollutants, which release from carburettor and the engine crank case flumes in addition to the engine exhaust. Due to quenching the hydro carbons are formed in SI …

Effects of emission from automobile engines on human beings 1. Hydro carbon ——- lunge diseases. 2. Lead ———— blood cancer. 3. Carbon monoxide———— heart blood circulatory problem. 4. Nitrogen oxides———- asthma/bronchitis.
Merits and demerits of using hydrogen as a fuel Merits of using hydrogen as a fuel Hydrogen can obtained from various resources and it is highly available in the environment.and it can also get by hydrolysis of water. It causes less pollution due to complete burn of air fuel mixture. It has no carbon content. …
Thermostatic Expansion Valve This type of thermostatic is used in industrial and commercial refrigeration system. This is an expansion device, and it is also known as constant superheat valve. In this ther are many different types of elements presented like evaporator, adjusting screw, feeler bulb, diaphragm, spring, valve, strainer. Let, Pb- pressure in …
Evaporative condenser Evaporative condenser is nothing but the evaporative cooling. That means the water evaporates, when the water comes in contact with the refrigerant flowing in the condensing coil. Evaporative condenser consist of a condenser coil, pump to circulate water from the sump, eliminators, fan, spray header and it’s nozzles, and a float valve. …
Regenerative Air Cooling System. Regenerative Air Cooling System is the another modified form of simple cooling system and it is additionally presented with a heat exchanger. Regenerative air cooling is used when the cooling turbine discharge temperature of a simple system is more. And this types are mostly is used in supersonic aircraft and rockets …
Refrigeration: Refrigeration is used to maintain and to reduce the temperature below that the surrounding temperature. It is done by the process of removing heat from an object under controlled conditions. It is used to store the products at required temperature. Ice can be manufactured easily through refrigeration. Advantages of Liquid Gas Refrigeration: .This refrigeration …

Electrical type temperature indicator: Electrical temperature indicator is used to identify the changes occur in the temperature of a required medium, In this type of indicator unit it consist of an engine which has an insulated wire connected to the panel to obtain an exact temperature indication. by making all the connections perfect it is …
USES OF ANTI-FREEZES: It is used at some places that falls below zero degrees temperature. Due to zero degrees when the water from the cooling system enters in to the engine jackets and at certain stage, at zero degrees it gets freeze by this the engine parts may gets damage like cylinder blocks, pipes and …
Fuel feed system in diesel engines: In this process the air is taken into the cylinder and compressed during the compression stroke and fuel is directly passed through the combustion chamber with high pressure at the end of compression stroke.the fuel inside the chamber burns due to the compressed air or self ignition. For this …
