Since the reform and opening up, China has always upheld development concept of science technology, under trend technology globalization, a large number foreign automobile engine been gradually introduced into production China’s industry. In this paper, author mainly discusses application microcontroller in speed measurement system, will also explain from perspective embedded system.

In this paper, we present an extension to the TSALB problem (Time and Space constrained Assembly Line Balancing) with ergonomic risk restrictions. This ergonomic risk is defined from the task durations and their categories regarding to the risk factor for the workers. A study is presented through a case linked to an engine assembly line in the Automobile industry, considering variable demand.

Engine oils are widely used for lubrication purposes in automobile and related industries. Viscosity Index (VI) improver has found its largest commercial applications as additives to engine oils. Examples are power steering fluid, aircraft piston engine oils, modern internal-combustion engines, turbine engine oils (stationary and aircraft), and industrial gear oils. Viscosity Index improvers ar...

In this paper FPGA is used as the master chip to design the new fourphase sensorless BLDC(brushless direct current) motor control system of automobile engine cooling fan. The design uses BEMF zero-crossing detection algorithm and the hardware modular design approach, while the open-loop circuit adopted to raise the frequency and voltage and the digital phase-shift circuit based on FIPS algorith...

This paper discusses a method for fault detection and isolation (FDI) in continuous dynamic systems. A key aspect of this approach is the coupling of a qualitative diagnosis engine and a monitoring system that computes symbolic feature values through a signal-to-symbol transformation on the continuously sampled measurement data. Signal analysis techniques with a sound statistical basis are empl...

Abstract—This paper explain the primary balancing of single cylinder engine and optimizing the counter balancing mass to reduce the unbalanced forces coming on the crankshaft. After optimizing, the effect of primary balancing is validated. After primary balancing, the vibration is measured on the engine at various locations. Balancer shaft is designed for the unbalanced forces exist after prima...

Abstract When checking and cleaning whether there is carbon deposit in the cylinder of gasoline engine, it often time-consuming laborious, process complicated. Once disassembly assembly not place, its service life will be affected. with carburizing agent agent, difficult to fully contact wall, so effect poor easy leave chemical composition engine. In this paper, some common ways engine are stud...

contamination of soil and air due to hydrocarbon is a global issue and bioremediation providesprobably the best way to remediate the contaminants. the current study shows the biodegradation of crudeoil, diesel and used engine oil by a newly isolated bacillus cereus strain drdu1 from an automobile engine.hydrocarbon degrading strains were screened on bh (bushnell and haas broth) agar supplemente...
