The comfort performance of car seat is important factor while producing car seats, each layer of the car seat is tested separately on classical testing machines, which lacks the real car seat performance when all layers are sandwiched. The complication of car seat design and the testing method bring a great demand of portable device which can measure the comfort performance of the real car seat. In this research a novel portable device is designed which work with special heat flux sensor and the device is connected to computer by USB port and values of heat flux temperature of the water and temperature of the surface is provided by the software. Heat flux sensors measure the heat transfer through a surface, and are expressed in kw/m2. The software controls the heating plate adjustment using PID controller. The device is tested with real car seat and shows repeatable and reproducible results.

Flux Sensor

The development and evaluation of a novel hybrid method for obtaining heat flux measurements is presented. By combining the spatial and temporal temperature measurements of a heat flux sensor, the time response, accuracy, and versatility of the sensor is improved. Sensors utilizing the hybrid method are able to make heat flux measurements on both high and low conductivity materials. It is shown that changing the thermal conductivity of the backing material four orders of magnitude causes only an 11% change in sensor response. The hybrid method also increases the time response of heat flux sensors. The temporal response is shown to increase by up to a factor of 28 compared with a standard spatial sensor. The hybrid method is tested both numerically and experimentally on both high and low conductivity materials and demonstrates significant improvement compared with operating the sensor as a spatial or temporal sensor alone.

Natural Decomposition

Biogas is the term used for the gas made from the natural decomposition of Organic (plant or animal) materials. It is Produced when the materials are digested by bacteria in a situation where little or no air is present (anaerobic digestion). Biogas consisting of approximately two-thirds methane (CH4) and one-third carbon dioxide (CO2) burns well and can be used to provide energy in the form of heat or electricity. The main practical sources of biogas are sewage, animal manure and the organic materials in household refuse or industrial waste. Like other renewable energy sources, biogas is a stored form of solar energy (since it originates from plants which used the sun’s energy to grow). An experimental evaluation was carried out to compare the performance of an IC engine (SI) Using Biogas as fuel blended with petrol in different proportions to that of only petrol as fuel. The performance study carried out in a four cylinder SI engine shows that this can better be used as an automotive fuel with a comparatively much lesser cost than the conventional fuels. The results show that because of the low calorific value of biogas the thermal efficiency is lesser than that of petrol and remains same at low and high out puts. Same is the case for volumetric efficiency. Biogas is an excellent and economical fuel for both petrol and diesel engines. However the power obtained is less than that of liquid fuel. Biogas is a cheaper and better fuel for cooking, lighting and running engines.
