In fact, the working process of diesel engines with petrol engine the same, each work cycle has gone through intake, compression, for power, exhaust four stroke. However, since diesel fuel is diesel fuel, the viscosity than gasoline, not easy to evaporate, while the auto-ignition temperature but lower than gasoline, thus forming a combustible gas mixture and ignition are different from the gasoline engine. In the intake stroke diesel inhaled pure air. When near the end of the compression stroke, diesel fuel injection pump through the oil pressure up to 10MPa or more, through the injector injected into the cylinder, in a very short period of time is mixed with hot air compressed to form a combustible mixture. Because the diesel engine compression ratio (usually 16-22), so the compressed air pressure inside the cylinder end up 3.5-4.5MPa, while temperatures up 750-1000K (and gasoline engine hybrid gas pressure at this point will 0.6-1.2MPa , temperature of 600-700K), much higher than diesel fuel auto-ignition temperature. Diesel generators belong captive power AC-powered device type generator set suppliers, it is a small independent power generation equipment, internal combustion engine powered, driven synchronous AC generator and produce electricity. Modern diesel generator set by a diesel generator manufacturer, a three-phase AC brushless synchronous generator, control box (screen), cooling water tank, couplings, fuel tank, muffler and public base and other components of the overall steel. Flywheel generator housing front cover of the diesel engine using the axial positioning shoulder formed integrally directly connected, and the cylindrical rotating flywheel by a flexible coupling direct drive generator, which are secured together by a screw connection mode, so that the two It is connected into a steel body, to ensure the concentricity of the range diesel engine crankshaft and the generator rotor prescribed. In order to reduce the vibration of the unit, in diesel engines, generators, water tanks and electrical control box, and other major components and connections common base, usually they are equipped with rubber shock absorber or cushion. Control and operational mode according to classification, can be divided into field operations units, compartment and automatic operation of the generator set generator set. 1) on-site operation of the generator set. The operator of the generators in the engine room to start, closing, speed, sub-gate, parking and other operations. Vibration, noise, oil mist and exhaust of such generators run produced adverse effects on the operator's body. 2) compartment operating units, such turbine engine room and control room provided separately generator prices, operating personnel in the operating room to room within the diesel generator to start, speed, stop and other operating units, and units The operating parameters monitoring, auxiliary engine room also implement centralized control. Compartment operation may improve the operator's working environment. 3) automated generators. After years of research the relevant units, automatic diesel generator set enabling unattended, including the crew from the start, automatic voltage regulator, automatic frequency, load transfer, automated and car, according to the load automatically increase or decrease the size of the unit, the automatic processing failure automatically record the printer group can 10-15s start automatically after power failure, instead of the mains supply.
