The advantages of diesel engines has been known for many riders, fuel-efficient, low-speed torque, easy maintenance, reliability, long life and so much more than the gasoline engine to reach the heights. Among them, the torque advantage of the most prominent. The displacement of domestic Europa de 2.0T generation diesel engine, maximum torque of 310N \ m, to achieve the level of 3.0L gasoline engine. High torque for diesel cars has brought a large number of loyal followers. Here let us look at the mystery of diesel engine with high torque output.

    As we all know, the engine torque from the piston acting in the course of the energy generated by the driving force of the piston and cylinder from the combustion of fuel the rapid expansion of the volume of air generated strong pressure. In other words, diesel engine "air" and "injection" together determine the engine torque advantage.

    From the works of view, is the pressure of diesel engine using natural methods, and the gasoline used to light the way of comparison, can support greater air compression ratio. In general, the gasoline engine compression ratio of 12:1 was already very advanced, while the diesel engine's compression ratio can be achieved very easily as high as 20:1. High compression ratio of air quality to support more fuel in combustion, increase power levels, while high pressure inside the cylinder high torque and power can create the conditions for the output.

    In order to play advantage of high compression ratio engine, a new generation of diesel engine turbocharger technology, by more air into the cylinder, to enhance the compression ratio and thus enhance the purpose of torque. However, the use of turbo technology in the early stage of turbo lag has been facing problems, that is in the car at the initial stage, the exhaust driven turbo small enough to work, but this time as a naturally aspirated torque output. To address this problem, Europa Germany began to use variable geometry engine technology (VGT), by continuously adjusting the angle between the turbocharger turbine inlet, to protect the engine can be in any case showing strong momentum.

    Advantage of a new generation of high torque engines also benefit from advanced fuel injection system. Take Europa German engine equipped with a new generation of electronically controlled high pressure common rail fuel injection (CRDi), because the high pressure hydraulic pump controlled separately, so the injection pressure can reach 1600bar level, better fuel atomization. Moreover, high-pressure common rail system through the ECU also realize the fuel injection pressure, injection timing and the precise control of fuel injection quantity to substantially enhance the full degree of burning, this is precisely the basis for generating high torque.

    Variable geometry turbocharger (VGT) and high-pressure common rail technology (CRDi) of the intervention, the advantages of high torque makes the diesel engine has been fully realized. Test data show that the new generation of diesel engine and gasoline engine emissions compared to the same power can be increased by 50% while energy consumption is reduced by 30%.

    With the soaring energy demand and the surge in car ownership, how the pursuit of power and the "people, cars, environment," sustainable development to find a balance between the see, has become the auto industry had to face the issue, and diesel-powered is the best direction.
