We all know that diesel engines, in principle, work in the same way as gasoline engines do. Both kinds of engines are internal combustion engines, but each of them has its characteristic features. Now let us compare the diesel engine with the gasoline engine. Firstly, the explosive mixture of the gasoline engine is provided by a carburetor, but in the case of the diesel engine the supply is affected by an injection or “jerk” pump which forces a “shot” of fuel into each cylinder in turn according to the correct firing sequence. Secondly, the fundamental difference between gasoline and diesel engines is that in the gasoline engine the source of the heat for igniting the charge, namely, an electric spark, is generated outside the engine, and is taken, as it were, into the waiting charge at the required instant. In the diesel engine the source of heat for igniting the charge is created within the engine by compressing pure air to a degree that will initiate combustion and then injecting the fuel at the right time in relation to the movement of the crankshaft. According to the paragraph, which statement is true? A. Diesel engines have the same characteristic as gasoline engines do. B. Diesel engines don’t have the same characteristic as gasoline engines do. C. Both A and B.
