Failure Investigation Report on Different Components of an Automotive Engine
This paper presents an investigation report of different components failure which affect the performance of an automobile engine. The premature breakage of a four cylinder diesel engine block, crankshaft, camshaft, crankshaft bearing, camshaft bush, engine oil pump was reported. It is found that the failure of each component having the same reason for its failure as reported from different place. Thus it affected the performance of the vehicle and it is very expensive for the customer to replace the damaged parts for several times. In this paper, we presented detailed analysis of the causes for the failure along with preventive suggestion to maintain the engine for better performance.
Improvement in Millipore and Implementation of Pneumatic System for Burr Removal
Each component or a part which is nature or arranged by human has an end period or disillusionment time. We as masters influence an average endeavor to find the life to time and make various arrangements to diminish the failure and augmentation the life time. Machining is improved the situation screws, Cylinder heads, Cylinder block, crank cases, cover cases and crank & Main Bearing (MB) Caps. Throwing is improved the situation cam shafts and motor external bodies. Every part component has a remarkable request of handling. It takes after and request of either throwing or manufacturing and machining. Furthermore, in view of the tainting in the motor, the motor keeps running with a considerable measure of issues like wear & tear, Huge clamor, Friction, Vibration and so on, of interior parts of the motor. These burrs are the main consideration for the sullying caused in the motor get together. Because of this client disappointment is going high. To control this specific strategy are taken after and kept up.
Development of Technique to Measure Stress on Connecting Rod during Firing Operation
When measuring the stress generated on connecting rods during operation with a strain gauge there are technical problems in taking the signal wires outside of the engine. As a means to solve this problem, the authors have developed a wire take-out method which consists of a steel wire to hold the signal wire and a tensioner to give tension to the steel wire. The adoption of this technique made it possible to measure the stress on connecting rods at a high speed range exceeding 10,000rpm, which has been impossible before. The results of analysis obtained by the wire take-out method revealed that speed ranges exceeding 10,000rpm generated a high frequency fluctuation due to the bending vibration of the connecting rod.
