OTTO CYCLE



The cycle which was introduced by Dr. A.N.Otto a german scientist is called otto cycle.Now a days pertol and gas engines follow this cycle.This cycle consists of the following four processes:

                                                        1.Two reversible adiabatic or isentropic processes,and
                                                        2.Two constant volume processes                                                        

Process1-2:
                 Process 1-2 is the isetropic compression process.During this process,the pressure increases from p1 to p2 and temperture increases from t1 to t2 but the volume decreases from v1 to v2 and entropy remanis constant

Process 2-3
                 process 2-3 is a constant volume heat addition process during this process this pressure,the increases from p2 to p3 the temperture increases from t2 to t3 and the entropy increases from s2 to s3

BRAKE PERFORMANCE TEST OF AN AUTOMOBILE | BRAKE SERVICE LAWS AND REGULATIONS WORLD WIDE

Automotive Service Technicians and Mechanics Brake Performance Test of an Automobile The brake performance test of FMVSS 105 defines the minimum needs for the brake system on any vehicle driven on the road. The technician should know a bit about the performance test, not for the sake of being able to quote government regulations. Parts of the test define the kind of performance a brake system should deliver after the vehicle serviced. The brake performance test divided into eighteen stages and begins with a new set of brakes on a test vehicle. The first stage is to install the test instruments on the vehicle and verify that they operate correctly. The vehicle then goes through the test called “first effectiveness test”. This test is performed with new brake linings before they have had a chance to burnish in. Rules and Regulations for driving an automobile The vehicle makes six stops from 30 mph and six stops from 60 mph. One of the stops from 30 mph made in 57 feet or less. One s...

What Is Mechanical engineering ?

Mechanical engineering is the discipline that applies the principles of engineering, physics, and materials science for the design, analysis, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the design, production, and operation of machinery. It is one of the oldest and broadest of the engineering disciplines. The engineering field requires an understanding of core concepts including mechanics, kinematics, thermodynamics, materials science, structural analysis, and electricity. Mechanical engineers use these core principles along with tools like computer-aided design, and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others. Mechanical engineering emerged as a field during the industrial revolution in Europe in the 18th century; however, its development can be trac...
