Small displacement turbocharged engines flooded, 2.0 self-priming is really not as good as 1.5T engines?

With the increasingly stringent policies of various countries on emission standards in recent years, car companies have to continue to explore how to save energy and reduce emissions, in fact, in the end, there are two ways, or the displacement is unchanged and the thermal efficiency is improved. Or reduce the displacement, but the increase in thermal efficiency is so difficult, so reducing the displacement has become a helpless move, but the reduction in displacement also means that the power is reduced, in order to ensure the power output as much as possible, the small displacement turbocharged engine came into being. 1.5T turbo engine has become the main engine of many car companies more and more, so how much displacement self-priming engine is equivalent to 1.5T turbocharged engine?

Turbocharged engine compared to the same displacement of self-priming engine, tends to have a greater advantage in torque, the current 1.5T turbo engine, roughly equivalent to 1.8L-2.5L self-priming engine, due to the different technical levels of each car company, it is difficult to give an accurate number, such as the following models.

The 1.5T engine of the weakest chicken

At present, there are several third- and fourth-line independent car brands, including Southeast Automobile, Brilliance Automobile, Zotye Automobile, Landwind Automobile, etc., using Mitsubishi's turbocharged engine, including various magic versions. These engines can be said to be technologically advanced if placed 10 years ago, but in 2021, they can only be said to be weak chickens, and the weak power and fuel consumption are still high. For example, the TNN4G15T engine on the Zotye T300 is the 1.5T engine with the weakest chicken on the market, the maximum horsepower of 144, the maximum torque of 215 Nm, and the maximum torque platform is also very narrow, 2500-4500 rpm. As an analogy, toyota Camry equipped with a 2.0L engine, the maximum power of 131KW (178 horsepower), the maximum torque of 210 Nm, it can be said that Zotye's 1.5T engine, the parameters are not as good as Toyota's 2.0L self-priming engine, probably only equivalent to the same level of technology level of 1.8L self-priming engine level.

The most powerful 1.5T engine

Of course, there are also many eye-catching 1.5T engines on the market, and their parameters can be comparable to 2.5L self-priming engines. Taking Toyota's 2.5L engine as a reference, Toyota is one of the few car companies that still use self-priming engines on the main model, with a maximum power of 154 kW (209 hp) and a peak torque of 250 Nm

1. Honda's 1.5T engine

Honda 1.5T engine codenamed L15BL is applied on guandao, CRV, Accord and other models, with "intake and exhaust dual VTC", "in-cylinder direct injection" and "high response turbocharging" three technical characteristics, the parameters of this engine are very eye-catching, can burst out 193 horsepower, 243 Nm power, very close to Toyota's 2.5L self-priming engine. The maximum torque platform of 2000 to 5000 rpm is also relatively broad, and in terms of fuel economy, Honda's engine is even stronger, but in terms of smoothness, due to the intervention of the turbine, the smoothness is still inferior to Toyota's self-priming engine.

2. SAIC Blue Core 1.5T engine

On the new third-generation MG 6, we saw SAIC's latest 1.5T engine, which was jointly developed with GM, which can output up to 181 horsepower and up to 285 Nm of power, and officially claimed to have 350bar ultra-high pressure direct injection, ePower Control electronic control turbine technology, original high-performance enhancement kit and other technologies. This engine is completely comparable to or even surpass the 2.5L self-priming engine, and at 1500 rpm, this engine can output maximum torque, making the MG 6's low-speed explosive power stronger.

In addition to the above two engines, the 1.5T engines of Ford, Lynk & Co, Mercedes-Benz and other car companies also have a good power level. Although many self-priming parties insist that self-priming is king, but the trend of small displacement turbocharged engines is unstoppable, Toyota, Mitsubishi and other brands are already the only main engines on the market that adhere to self-priming engines, from the experience point of view, small displacement turbocharged engines, although in the absolute linearity of the power is not as good as the self-priming engine, but the maximum torque platform is narrower, the explosiveness of the power is better, more suitable for high-speed driving. At the same time, the wider torque platform also means that the turbocharged engine does not need to be very high to produce enough power, which helps with fuel economy. Of course, there are too many engines on the market, if you want to understand the performance of the specific 1.5T engine, you can pay attention to us, and then private messages to our brands and engine models, we will reply one by one.
