Automotive Essay

Automotive Vehicles Q1. Can discharge injection systems be sedulous in SI locomotives? Provide valid causality for your chastise? Yes, provide injection systems can be(argon currently being) apply in SI engines. Initially the SI engines had carburettors for supply of kindle to the enthusiastic at the stake domiciliate. During the suction stroke vacuum is created in the combustion chamber, this shun pressure causes communication channel to rush in through the carburetor and this causes the kindle to be sucked in when the air flows through the venturi. To limit the engines more efficient nowadays render injection systems are being use. In case of SI engine the fuel injectors inject the fuel air classification unlike the fuel injectors in CI engine which further inject the fuel. defend day engines capture electronic controlled fuel injectors. The fuel injector is controlled by an electronic control unit (ECU). The ECU is machine-accessible to various sensor s which go away it feedback so as to judge the amount fuel to be injected so as to image maximum efficiency at all times and abet increase power payoff as and when required. The fuel injectors withal ensure maximum fragmentation of the fuel-air miscellanea thereby change magnitude the efficiency. Q2. Why Petrol railway locomotive is not used for heavy machines/trains/applications? Petrol engines are fundamentally SI engines.

In SI engines the once the fuel-air mixture is compressed, a spark is assumption by the spark plug which ignites the game pressure mixture and combustion occurs instantaneously; where as in a CI engine the air is compressed and ! then the fuel is injected into the combustion chamber over a rate of flow of time. Because of this reason the energy presumptuousness by a petrol engine is over a short period of time and that given by the diesel engine engine is over a long-acting period of time. In case of heavy machines the machine willing have literal amounts of work to be done so it is preferred to have an engine which provides energy over a longer period of time therefore petrol engines are not used for these applications.
