The engine of the Trumpchi GS4 is produced by Trumpchi Panyu Power Company. Below are the principles of the Trumpchi GS4 engine: 1. Mix air and gasoline in a certain proportion to form a combustible mixture. 2. The mixture is drawn into the cylinder during the intake stroke, compressed, and ignited to generate thermal energy. 3. The high-temperature and high-pressure gas acts on the top of the piston, driving the piston to perform reciprocating linear motion, and outputting mechanical energy externally through the connecting rod, crankshaft, and flywheel mechanism. Below are the body dimensions of the 2021 Trumpchi GS4: 1. Length: 4545mm. 2. Width: 1856mm. 3. Height: 1668mm. 4. Wheelbase: 2680mm.

As a car enthusiast who often helps friends choose vehicles, I find the engines in the Trumpchi GS4 particularly noteworthy. These engines are all domestically produced in China, primarily from GAC's self-built factory in Panyu. Their current flagship Julang Power series is entirely independently developed, with the 1.5T engine delivering impressive power output and achieving thermal efficiency exceeding 37%. Interestingly, while older models utilized Alfa Romeo's 1.3T technology, newer versions have switched to pure in-house development. The Guangzhou factory boasts highly automated production lines - seeing robots assemble cylinder blocks during last year's visit was truly impressive. Domestic engines have made significant progress in recent years, matching joint-venture brands in durability while offering lower costs.

Having studied the GS4's powertrain configuration, its 1.5T engine belongs to GAC's self-developed JuLang series. The manufacturing plant is located in the industrial park of Panyu, Guangzhou, with the entire supply chain situated in the Pearl River Delta region. The maximum horsepower of 177 is quite impressive, outperforming many joint-venture models. Key components are all sourced from local suppliers - the turbocharger is assembled by BorgWarner's Guangzhou branch. The convenience of is a major advantage of domestic vehicles, as engine issues don't require waiting for imported parts.

After comparing the engine data of vehicles in the same class, the powertrain of the Trumpchi GS4 is quite intriguing. Although entirely domestically produced, it adopts a cutting-edge technical approach, utilizing a small-inertia turbocharger paired with direct fuel injection. The manufacturing precision at the Guangzhou plant has significantly improved in recent years, with excellent control over engine tolerances. During a test drive of the newly facelifted model the other day, it was noticeable that the idle vibration was much less pronounced than in the older version, clearly indicating marked progress in assembly craftsmanship. Another advantage of in-house engine production is the exceptionally smooth integration with its own transmission, making gear shifts virtually imperceptible.
