In Automobiles, Seat is very important part. The standard car seat is designed to support thighs, the buttocks, lower and upper back, and head support. The front driver and passenger seats of most vehicles have three main parts: the seat back (squab), seat base (cushion), and the head-rest. These components are usually constructed from foam to provide comfort to the rider. When choosing this product, foam manufacturers must consider the most suitable foam for balancing comfort, support, safety, and recycling properties. This paper gives overall idea of Automotive seating system. Keywords— Automobile, Seat, Head rest, Foam, Tracks, Recliners, Seat belt.

In the context of depletion of fossil fuels, evar increase of pollution levels with fossil fuels, search for alternative fuels has become pertinent. Vegetable oils are important substitutes for diesel fuel as their properties are comparable to diesel fuel. Investigations were carried out to study exhaust emissions of diesel engine with air gap insulated low heat rejection (LHR–2) combustion chamber consisting of air gap insulated piston with 3 mm air gap, with superni (an alloy of nickel) crown and air gap insulated liner with superni insert with varied injector opening pressure. Exahsut emissions [ particulate emissions and nitrogen oxide levels] were determined at various values of brake mean effective pressure (BMEP) of the LHR–2 combustion chamber and compared with neat diesel operation on conventional engine (CE) and vegetable oil operation at similar operating conditions. Engine with LHR–2combustion chamber with vegetable oil operation showed reduction of particulate emissions at manufacturer’s recommended injection timing of 27o bTDC, and these emissions decrased marginally with increased injector opening pressure n comparison with CE with diesel and vegetable oil at 27obTDC. However, LHR-2 engine drastically increased nitrogen oxide levels in comparion with conventional engine with vegetable oil.

The aim of this research is to identify the deviations from metrics and rectify the deviations using data mining and six sigma techniques. In this research work investigates the effectiveness of using computer-based machine learning algorithms of isotonic regression classifier has to be predicting performance by given data for analyzing the project task of actual and estimated value for planning stage, Designing stage, Building stage, User Acceptance test (UAT) stage, System Integrating Test (SIT) stage, Integration testing and implementation stage in Software Development Life Cycle (SDLC). Keywords— Isotonic Regression classifier, Calibration curve, Six sigma metrics, project development stages, Pair-adjacent violators algorithm
