If we take for example an internal combustion four stroke engine its basic design is almost the same as about a century ago since its invention but one thing is certain that the valve timing & ignition timing are extremely important for burning the fuel liquid or gas in an efficient manner.
Variable Valve Timing (V.V.T), Multi point electronic fuel injection( M.P.E.F.I) are few of the latest innovations but one thing is sure that the internal combustion engine efficiency did not ever went up the mark of45% maximum with respect to fuel spent and rest of about55% goes in a form of heat dissipation or a waste heat recovery system has to be installed to get an efficiency of86% to90% or even more in some cases.
The whole mechanism of engine lies on timing of combustion. The turning moment is maximum during the power stroke. The turning moment produced in this stroke is required to be distributed for the remaining strokes. For example:- The timing for a4 cylinder engine is 1-3-4-2.
It implies the power stroke will first happen in1st cylinder and then in3rd cylinder. After the power stroke happens in3rd cylinder, it moves to4th cylinder and then to2nd cylinder. If there is any delay in ignition timings, then it decreases the life of the engine.
Top Answer: Totally agreed, the theory of ignition is chemical reaction between the three elements of the fire trinagle which is fuel ( comustible material ) + heat + oxygen ... once we have a comustible material and oxyegen , if the temerature reaced to the degreee which is the ignition temerature , then the fire start, ... To stop fire , simply remove one of the traingle element ( eith ( fuel , or O2 or the heat) ...
Top Answer: 1- increasing engine temp (cooling system not work good) it leads to the gasket damaged
2- the cooler of cooling water and the engine oil is the same cooler (beige)
3- may be some oil leakage around the gasket
4- change in engine noise
5- the wariest case the engine temp. increased and the engine stop
Top Answer: Both are important , but its also depends on your budget. For Organic SEO you need to plan before6 months or more and for PPC you just need to start the campaign.There are many big organizations which are only Marketing through PPC because they have budget.
If you have done SEO (On Page Optimization) well then you don't need to pay more, because it will improve Quality Score of your ad with more impressions and low CPC.
By the way now a days Only Google can't help in Marketing , you also need to pay more attention to Social Media where you can find your targeted people.
