Eaton Char-Lynn Motor – Gdi Motor: What Are The Advantages?
The GDI Motor is a hot spot in the research and development of foreign internal combustion Motors in recent years. Experts believe that the emergence of direct injection technology of gasoline Motors has made automobile Motor technology a new era. It has replaced the traditional gasoline and diesel Motors in the 21st century and has become an ideal power unit for cars.
The GDI Motor research began in Germany. As early as the 1950s, Germany had a direct-injection two-stroke gasoline Motor loading market, and even loaded onto the prestigious SL-class Mercedes-Benz sedan, but it quickly disappeared. Later, German designers, whether Mercedes-Benz, BMW, or Volkswagen, took a frowning attitude toward direct gasoline injection. Because according to the test, they thought that the Motor was running poorly, the car could hardly be opened, and the exhaust gas problem could not be solved, so it stopped.
Development of GDI Motors.
The development of the GDI Motor can be described as being in Germany, but in Japan. The successful development of Mitsubishi Motors’ GDI Motor has caused the world’s automakers and Motor manufacturers to lag behind, so the world’s car industry has set off a boom in the development and utilization of GDI Motors. Since then, the development of gasoline Motors has taken another step, which will also promote the development of the world automobile industry.
The Eaton Char-lynn Motor describes the technical features of the GDI Motor:
Achieve low fuel consumption
In the ultra-thin burning, the injection time is before the ignition stroke, and the air density in the cylinder is high. The fuel is easily atomized after being injected through the high-pressure nozzle; and due to the action of the piston curved top, the mixture is vortexed and presented. The layered distribution, that is, the concentration of the mixed gas near the spark plug portion when the mixed eddy current is ascending, and the concentration away from the spark plug portion is low. When the concentration of the mixture near the spark plug is high, the fire is first ignited. When the temperature is increased, the temperature in the cylinder is increased, and the portion with a low concentration of the mixture can be continuously and stably burned. Figure 5 shows the process of gas mixture formation.
Achieve high power output
When the Motor is running at a large load, the Motor is required to have a large lifting power. The GDI Motor uses the vertical intake air to reduce the intake resistance, and the direct injection of the fuel in the intake stroke cools the intake air, thereby improving the intake efficiency. Due to the direct injection in the cylinder, the fuel is vaporized in the combustion chamber, and the heat of vaporization is heated. Cooling the inhaled air increases the density of the air; at the same time, the gasification of the gasoline in the cylinder also cools the combustion chamber, thereby reducing the tendency of the Motor to knock, so that the compression ratio can be increased when designing the Motor .
