In the face of growing environmental pollution, auto companies are trying to solve the new environmental protection standards that have been introduced. Many car companies are working hard on small-displacement engine models. On the one hand, to comply with the user's demand for low fuel consumption, on the one hand, it is based on the existing engine to promote better dynamics. Many people choose vehicles to be comfortable with the sense of smoothness and comfort of a ride. How can one choose the right car for a small-displacement engine? The following will introduce you to the performance of several popular small-displacement engines that are currently on the market. Let's take a look at a three-cylinder engine. First of all, for the majority of netizens, Ford’s 1.0T engine is only a three-cylinder engine, but Ford’s many models have already proven its strong strength. The technical strength of Ecoboost makes the engine stand out in terms of stability and overall output. The maximum power and maximum torque reach 125 horsepower and 170 Nm respectively. Although netizens ridiculed this small-displacement engine, the fuel consumption is still high, even with low displacement, but its direct injection in the cylinder, independent camshaft variable valve timing and improved boost technology make the fuel consumption of the 1.0T Carnival 1.5L is still low. Let's take a look at Mitsubishi's 1.2L engine, code-named 3A92, with a maximum horsepower of 78Ps and a maximum torque of 100Nm. The numbers are unpretentious, but they are extremely fuel-efficient and durable, and if they are introduced domestically, they are expected to have a place. Finally, let's take a look at BMW's 1.5T three-cylinder engine. BMW installed a balance shaft on the bottom of the three-cylinder engine to reduce vibration and noise. The vertical layout also alleviated the body vibration to some extent. Although there are only three cylinders, the compression ratio is also improved to 11:1. BMW is BMW after all! Ford 1.0T Ecoboost Turbocharged Engine After introducing the three-cylinder engine, let's take a look at the four-cylinder engine now! 1.2T turbocharged engine is the main thrust of the public engine, this model of the engine Volkswagen's more models, replacing the 1.6L self-priming models, this engine maximum horsepower 110Ps, maximum torque of 175Nm, excellent power performance, and lower fuel consumption. There is also Volkswagen's 1.4T engine, which can satisfy most people's demands for sports performance. However, if there is congestion in the urban area, there will be no advantage in fuel consumption. In addition, Honda's 1.5T four-cylinder engine in the same model performance amazing, powerful power is not the only advantage, this engine 5.4L 100 km fuel consumption is believed to meet many people's fuel economy requirements. Finally, Toyota 1.2T four-cylinder engine is mentioned. This engine core technology is well-placed, with a maximum power of 85kW and a maximum torque of 185Nm. Compared with other self-priming engines, VVT-i technology provides powerful fuel economy performance. Guarantee. Volkswagen 1.2T 4-cylinder turbocharged engine Not only joint venture brands are constantly introducing and optimizing their small-displacement engines, but also domestic brands are doing their best. With the ever-increasing environmental protection requirements, these small-displacement engines will respond more and more to the situation and develop rapidly.
