Toyota has been using turbocharged engines for 35 years, but in the past 20 years, Toyota rarely launches sedan models equipped with turbocharged engines. Until September and December 2016, the Toyota D-4T 1.2T turbocharged With the introduction of the new Corolla 1.2T engine and the launch of the Guangzhou GAC Toyota Ralink 1.2T model, Toyota is only officially opening the era of turbocharged cars as the main model in the Chinese market. There must be a surprise after a long time reunion. As the most compact turbocharged model of the Toyota D4 series, the D-4T turbocharged engine has the same advantages as the turbocharger with the same displacement in terms of power, fuel consumption, and environmental protection. Due to its outstanding performance in terms of power and fuel consumption, this turbocharged engine was highly praised for its "1.2T displacement but 1.8L power and 1.5L fuel consumption." In fact, such an evaluation is by no means an exaggeration. The Toyota D-4T 1.2T turbocharged engine incorporating many technological innovations is indeed evaluated in terms of power efficiency and fuel consumption. The 1.2T displacement is at a low speed (1500 rpm). Sub-) will be able to burst 1.8L displacement self-priming engine power, but at the same time the fuel consumption is only 1.5L self-priming engine level. The balance of such high-efficiency power output and economic fuel consumption can be just right, and it has a very close relationship with many innovative engine technologies used in the D-4T. Turbine hysteresis has been a key bottleneck for turbocharged engines. Because the turbocharger used in conventional turbocharged engines has a large volume and the turbine does not rotate smoothly at low speeds, it requires the turbine to intervene when the engine reaches a certain speed. Therefore, after the driver depresses the accelerator pedal, the turbine will not immediately intervene, but will need to wait for a moment before the power comes up. The throttle response speed is slow, and at low speeds, it cannot deliver sufficient power. In order to eliminate the lack of low speed power and slow response of the throttle due to turbo lag, the Toyota D-4T uses a miniaturized turbocharger to reduce the size of the turbine. The miniaturized turbine can be driven with only a small amount of exhaust gas. The turbine can also intervene quickly when the engine speed is low, and it can also provide strong power in the low speed range. Taking torque as an example, the Toyota D-T4 engine can achieve a peak torque of 185 Nm in the 1500-4000 rpm range, which is better than most high-power turbocharged engines, and the low-torque performance exceeds 1.8L. Naturally aspirated engine. While adopting a compact turbocharger, the D-4T also uses a water-cooled intercooler with a very high degree of freedom in layout, which minimizes the suction path and greatly shortens the throttle response time. Calling on the go to ensure the safety of new drivers while enriching driving pleasure. If the power goes up while the fuel consumption also increases, then the 1.2T D-4T turbocharged engine is also meaningless. The Toyota D-4T engine, while achieving high-efficiency power, controls fuel consumption to the most economical range. The fuel economy technology derived from the D-4 series plays an important role in this. The first is the turbine miniaturization technology we mentioned earlier. Due to the use of a miniaturized turbine, the D-4T can achieve the required rotational speed for turbine intervention without using a lot of fuel, saving fuel consumption. Followed by the comprehensive use of the famous Atkinson cycle and vertical vortex air intake. The Atkinson cycle design was adopted for the D-4T engine to reduce fuel consumption by changing the mechanical structure of the intake valve. At the same time as using the Atkinson cycle structure, D-4T also canceled the gas flow control valve on the basis of the cancellation of the injection manifold. The use of the shape of the intake port and the piston in the cylinder produced a longitudinal vortex, further enhancing the direct injection in the cylinder. The efficiency is called a fighter in a direct injection engine. Through the integrated use of turbo miniaturization design and Atkinson cycle + vertical vortex air intake, the Toyota D-4T turbocharged engine has successfully realized the efficient use of fuel, ensuring that every liter of fuel can be converted into highly efficient power. It also indirectly reduces exhaust emissions from the engine, protects the environment, and practices a highly efficient and environmentally friendly development concept.
