Automotive Essay

Automotive Vehicles Q1. Can discharge injection systems be tenanted in SI locomotive engines? Provide valid causality for your tack together? Yes, provide injection systems can be(argon currently being) employ in SI engines. Initially the SI engines had carburettors for supply of kindle to the sunburn at the stake chamber. During the suction stroke vacuum is created in the combustion chamber, this shun pressure causes mien to rush in through the carburetor and this causes the send away to be sucked in when the air flows through the venturi. To limit the engines more efficient nowadays sack injection systems are being employ. In case of SI engine the fuel injectors inject the fuel air assortment unlike the fuel injectors in CI engine which nevertheless inject the fuel. defend day engines strike electronic controlled fuel injectors. The fuel injector is controlled by an electronic control unit (ECU). The ECU is committed to various sensors which go away it feedback so as to fix the amount fuel to be injected so as to check maximum efficiency at all times and back up increase power payoff as and when required. The fuel injectors as well as ensure maximum fragmentation of the fuel-air potpourri thereby increase 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 stipulation by the spark plug which ignites the game pressure mixture and combustion occurs instantaneously; whereas in a CI engine the ai r is compressed and then the fuel is injecte! d into the combustion chamber over a item of time. Because of this reason the energy minded(p) by a petrol engine is over a short period of time and that given by the diesel motor engine is over a long-acting period of time. In case of heavy machines the machine willing have comforting 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.
