AutoBeta(AutoBeta.net)05/05 Report--

With the gradual maturity of turbocharging technology and the continuous introduction of policies to encourage small emissions, more and more automobile enterprises have focused on small displacement turbocharging. It can not only meet certain power requirements, but also maximize fuel consumption savings.

A few days ago, it was learned from an internal document of Dongfeng Nissan that Dongfeng Nissan Passenger Vehicle Company of Dongfeng Nissan Automobile Co., Ltd. had previously won the bid for the project of "Equipment Supporting and Power Connection of Huadu and Zhengzhou MR15DDT and 20DDT Projects". This means that Dongfeng Nissan will gradually replace the existing naturally aspirated engine with a new 1.5T engine code-named MR15DDT and a 2.0T engine code-named 20DDT.

At present, according to Dongfeng Nissan's models, except for the newer seven-generation Teana with 2.0T turbine engine, the rest of the models are equipped with naturally aspirated engines, including 1.6L, 2.0L and 2.5L. However, Nissan has also introduced the MR16DDT at the beginning of "MR" and is equipped with the previous generation of Trent and the current Infiniti and Nissan Juke, so this 1.5T engine will also use the same technology, the full name of the 1.5T in-cylinder direct injection turbocharged engine, of which "15" is 1.5L displacement,"DDT" is D: double overhead camshaft, D: in-cylinder direct injection, T: turbocharged.

Although from the perspective of these two engines, it is only a word difference. Among them, according to the comprehensive parameters of the current 1.6T engine, the maximum torque can reach 240 Nm;2400~5200 rpm, but due to the higher fuel consumption and cost, Nissan did not push this engine in China. However, the newly developed 1.5T engine will be more fuel-efficient than the 1.6T, and it will also have stronger power than the current 2.0L self-priming engine. It can also be compared to Honda's L15 series and Toyota's M15C series.

In addition, according to Dongfeng Nissan's earlier announcement of the winning bid, there is also a 1.3T engine code-named HR13DDT casting cylinder block, so Dongfeng Nissan's small-displacement turboisation will also include this entry-level 1.3T engine. Although the engine is not currently used in its models, it has been used in Mercedes-Benz A-Class, GLB and Dongfeng Renault. For this reason, with Dongfeng Nissan introducing 1.3T engine, it will also help to further reduce consumption tax, emission and fuel consumption data every day, as well as improve the power of its models, forming a high-low configuration with 1.5T.

In fact, Dongfeng Nissan, which is also the "Japanese Three Musketeers", seems to lag behind Honda and Toyota in turbine engines. After all, Honda and Toyota brands have already applied 1.0T and 1.5T engines and 1.2T engines to their mainstream models, while Nissan's mainstream models are still equipped with self-priming engines, and frequently encounter consumer complaints, so that their competitiveness is gradually lost. However, as Nissan gradually replaces the current mainstream self-priming engine with 1.3T and 1.5T engines, it may help it regain some market competitiveness.

According to the latest news at present, Nissan will soon launch the brand-new Qijun model and Xiaoke model will also be equipped with 1.5T and 1.3T engines respectively, and realize the first launch.
