Automobile Exhaust system

Exhaust system is created to lessen the noise level as well as the pollutant content of the exhaust in order to diminish the effects on the environmental caused by the vehicles. In automobile, the exhaust system lead the gases created by internal burning engine form exhaust ports of its cylinders till the tailpipe and then out into the atmosphere. Compression and Vacuum: Engine compression testing requires extensive amount of time particularly when there is difficulty in removing the spark plugs and for its exact check, it really requires compression gauge. Engine will fail to start when there is not enough compression, therefore, for an engine to run it requires these things. The availability of sufficient compression to raise air temperature of air fuel mixture, engine should be high enough so that a spark can easily start adequate combustion process. Once the cranking vacuum is more than 3”, there is a great possibility for an engine to run as there is enough compression.
