Which are the reference fuels for knock rating of S.I. Some modern diesel engines no longer require a glow plug.Ħ. The compression ratio is high enough to combust the diesel without the aid of sparkplugs Answer Most diesel engines will have a ‘glow’ plug, this gives of enough heat to help get the engine started, the heat generated from the first few revolutions together with the compression from the piston is enough to ensure the engine keeps running. roots/screw or centrifugal), some early uses superchargers were driven directly off the crank shaft.ĥ. Supercharging usually refers to belt driven compressor (I.E. Supercharging is a method of increasing an engine’s power output, by forcing air into the engine under greater than atmospheric pressures. Scavenging is process of flushing out burnt gases from engine cylinder by introducing fresh air in the cylinder before exhaust stroke ends. What are the Advantages and Disadvantages of using LPG in Car?
The gas produced in this reaction rapidly expands forcing the piston down the cylinder on the power stroke.Ģ. Chemical energy is released when the fuel-air mixture is ignited by the spark in the combustion chamber. The internal combustion engine converts chemical energy into useful mechanical energy by burning fuel.
