Diesel Engines Diesel engines are everywhere; they are used in all sorts of vehicle platforms. From Volkswagen Jetta’s‚ to big eighteen wheel tractor trailer trucks. They provide more torque then a regular gasoline engine because of the long stroke of the piston. Most diesel engines make peak torque at very low rpm. Diesel engines do not have spark plugs. They develop combustion by heating up the air going into the cylinder‚ while the air is heated the fuel injector sprays into the bowl of

Chapter 11 Internal Combustion Engines 11.1 Introduction Internal combustion engines differ from external combustion engines in that the energy released from the burning of fuel occurs inside the engine rather than in a separate combustion chamber. Examples of external combustion engines are gas and steam turbines. The gas turbine power plant utilizes products of combustion from a separate combustor as the working fluid. These gases are used to drive the gas turbine and produce useful power. The
