Turbo 100: por qué NO es el PureTech que todos temían | Motorparts

This week Stellantis presented the new Turbo 100 in Madrid, and I took advantage of the event to analyze it in person. The usual reaction to a 1.2-liter three-cylinder engine from the group is to assume it's just another evolution of the PureTech. The conclusion, after studying it thoroughly, is the opposite: this engine is not a continuation of its predecessor. In this video, I provide a strictly technical analysis of the third-generation EB2, without controversy, reviewing the solutions it applies in each of the areas that caused problems in previous engines: 🔧 The open deck block with a central island and the cast iron cylinder liners inserted into the mold during the aluminum pressurization process. 🔧 The 1:1 balance shaft and its role in controlling the primary forces of a three-cylinder engine. 🔧 The real source of the PureTech's oil consumption: the relationship between piston rings, soot, and the droplet-to-gas transition in cold direct injection. 🔧 🔧 The increase in injection pressure from 250 to 350 bar and its effect on droplet size and evaporation. 🔧 The variable geometry turbocharger and the Miller cycle: how the effective pressure is reduced at the end of the compression stroke and where the gain in pumping losses occurs. 🔧 DLC-coated piston rings, iron oxide piston skirt priming, and the square-section ring for thermal control. 🔧 The transition from a wet timing belt to a silent link chain system. 🔧 The rocker arm with a bearing between the cam and valve, and the general problems with the PCV valve. I conclude by answering the most frequently asked questions about this engine, including its reliability, with a technically sound verdict. For those who want to delve deeper into specific engines—why they fail and how they are rebuilt, without marketing hype—I am preparing engine content. If you're interested, leave your email and I'll let you know 👉 http://motorparts.es/ At Motorparts, we're dedicating this analysis to the Turbo 100, the new engine with which Stellantis is updating its entry-level range. The Peugeot Turbo 100 uses the PureTech Gen 3 engine, the third generation of the PureTech family, and it's important to understand it properly before lumping it together with the previous PureTech engine: the Stellantis Turbo 100 shares the same displacement and three-cylinder architecture, but the internal engineering is different. As a good example of a modern 3-cylinder engine, the third-generation Stellantis 1.2 PureTech incorporates a timing chain, a variable geometry turbocharger, 350 bar injection, and a Miller cycle. Those of you who follow the channel know that 3-cylinder engines face challenges in terms of balancing and thermal management, and this Peugeot EB2 engine—known internally as EB2LTED in its hybrid variant—addresses them with solutions that we review step by step in the video. The journey of this 1.2 PureTech engine begins with an open-deck block with a central island, passes through the pistons and rings, and reaches the cylinder head. If you're familiar with the PureTech 1.2 turbo, you'll clearly see what's different compared to the classic PureTech 1.2: this generation of Peugeot 1.2 is not the same 1.2 PureTech that caused such a stir. That's why we insist so much on separating generations when we talk about engine mechanics. Its commercial debut comes with the Peugeot 208: the Peugeot 208 Turbo 100 is one of the first models to receive this engine, as part of the strategy with which Peugeot and the Stellantis group are updating their gasoline lineup. For anyone interested in the Peugeot PureTech and the evolution of the Stellantis 1.2 PureTech, now is the time to understand the real technical difference. In short, the Turbo 100 represents an engineering leap forward compared to the previous PureTech engine. The Peugeot Turbo 100, and by extension, all Stellantis Turbo 100s, demonstrate that a well-designed 3-cylinder engine can overcome past problems. At Motorparts, we'll continue analyzing this and other engines, because understanding mechanics and engines—from the Peugeot 208 to the rest of the Peugeot 1.2 range—is what drives us. The Peugeot EB2 engine, the EB2LTED, the Miller cycle, and the PureTech Gen 3 family offer much more to explore, and this video about the PureTech 1.2 turbo is just the beginning. 👉 If you enjoyed the content, don't forget to subscribe, like, and share your opinion in the comments.
