This document describes research on compressed air engines. Compressed air engines compress and store air at high pressure, then use the stored pressurized air to power pistons instead of combusting fuel. Researchers have studied ways to improve efficiency, such as modifying piston designs and using multi-way valves. One study achieved an output power of 1.92 kW, torque of 56.55 N-m, and maximum efficiency of 25% using a 0.5L engine operating at 2MPa supply pressure. Compressed air engines reduce emissions by replacing fuel combustion and have potential applications in transportation and industrial machinery.

mechanism to generate electricity using rack, pinion and speed increasing gear box and generator
and store compressed air with the help of piston cylinder compressor arrangement. Whenever the
vehicle is allowed to pass over the speed breaker dome, it gets pressed downwards. As the springs are
attached to the dome, they get compressed and the rack, which is attached to the bottom of the dome,
moves down in reciprocating motion. Since rack has teeth connected to pinion there is conversion of
reciprocating motion of rack in to rotary motion of pinion, but the two gears rotate in opposite

1) The document discusses the design and analysis of an engine that runs on compressed air for vehicles. It aims to reduce pollution by using compressed air instead of gasoline or diesel.
2) The engine was tested on a kinetic K4 100cc petrol engine by modifying the camshaft to open and close the intake and exhaust valves simultaneously to allow continuous flow of compressed air. This allowed the vehicle to run at up to 30kph.
3) Compressed air vehicles have potential advantages of being lightweight, cheap to operate, safe for flammable environments, and zero emissions. However, challenges remain in increasing their performance and range. Several companies are working to develop compressed air cars commercially.
This document discusses compressed air engines. It describes how a compressed air engine works by using compressed air instead of combustion to power the engine. The compressed air is stored in high-pressure tanks and expands to move the pistons, similar to how combustion moves pistons in a gasoline engine. Compressed air engines are more eco-friendly than gasoline engines as they do not involve fuel combustion or emissions. However, they have less energy storage capacity than gasoline engines due to the properties of compressed air. The document also outlines the components, specifications, working principles and advantages/disadvantages of compressed air engines.
The document discusses the design and analysis of an engine for compressed air vehicles. It begins with an introduction to compressed air vehicles and how they work using stored compressed air instead of combustion. The engine design is modified from a typical 4-stroke internal combustion engine, with changes to the piston, cylinder, and camshaft to operate on compressed air. Experiments were conducted modifying a 100cc petrol engine to run on compressed air, achieving speeds up to 30kmph. The document outlines the basic operation of a 4-stroke engine and discusses modifications made to the camshaft profile to optimize the engine for compressed air. It also summarizes the results of other studies on compressed air engines and vehicles. Expected benefits are that compressed air vehicles would
The document discusses modifying a 4-stroke engine into a compressed air engine (CAE) that runs on compressed air. It describes the layout of the modified CAE, which includes a compressed air tank, throttling valve, piston engine, and exhaust. The modified 2-stroke engine takes in compressed air from the tank through the throttling valve into the engine cylinder to power the piston from top dead center to bottom dead center, generating useful work output. Testing was performed on the modified engine to analyze the effectiveness of running it on compressed air.
This document provides an overview of the revised process for Assessment and Accreditation of higher education institutions by the National Assessment and Accreditation Council (NAAC) in India. Some key points:
- The revised process aims to make the accreditation process more robust, objective, transparent, scalable and ICT-enabled, while reducing its duration.
- It involves a Self-Study Report submitted by the institution, followed by an online assessment involving both system-generated scores (about 70%) and peer judgement (about 30%).
- NAAC's core values for assessment include contributing to national development, fostering global competencies, inculcating values, promoting technology use, and the quest for
This document provides an overview of the revised process for Assessment and Accreditation of higher education institutions by the National Assessment and Accreditation Council (NAAC) in India. Some key points:
- The revised process aims to make the accreditation process more robust, objective, transparent, scalable and ICT-enabled, while reducing its duration.
- It involves a Self-Study Report submitted by the institution, followed by an online evaluation (about 70% weightage) and peer assessment (about 30% weightage) to determine an overall score.
- Guidelines and manuals have been revised separately for universities, autonomous colleges, and affiliated/constituent colleges to suit their unique characteristics and needs.
The document provides guidelines for accredited higher education institutions to establish an Internal Quality Assurance Cell (IQAC) and submit Annual Quality Assurance Reports (AQARs). It outlines the objectives, functions, benefits and composition of the IQAC. Key responsibilities include developing quality benchmarks, collecting feedback, documenting best practices, and preparing the AQAR. Institutions must submit the AQAR online annually via their NAAC portal. The revised format aligns with NAAC's new accreditation framework and will help institutions strengthen quality culture and databases for future assessments.
