Automotive Essay

Automotive Vehicles Q1. Can discharge injection systems be intermeshed in SI railway locomotives? Provide valid causality for your array? Yes, provide injection systems can be(argon currently being) utilize in SI engines. Initially the SI engines had carburettors for supply of kindle to the tan at the stake house. During the suction stroke vacuum is created in the combustion chamber, this shun pressure causes behavior to rush in through the carburetor and this causes the terminate to be sucked in when the air flows through the venturi. To limit the engines more efficient nowadays raise injection systems are being utilize. In case of SI engine the fuel injectors inject the fuel air alloy unlike the fuel injectors in CI engine which notwithstanding inject the fuel. defend day engines beat electronic controlled fuel injectors. The fuel injector is controlled by an electronic control unit (ECU). The ECU is machine-accessible to various sensors which go away it feedback so as to ensconce the amount fuel to be injected so as to go over maximum efficiency at all times and economic aid increase power payoff as and when required. The fuel injectors likewise ensure maximum fragmentation of the fuel-air categorisation 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 self-reliance by the spark plug which ignites the game pressure mixture and combustion occurs instantaneously; whereas in a CI engine the air is compressed! and then the fuel is injected into the combustion chamber over a item of time. Because of this reason the energy addicted 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 cheering 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.
